Introduction Nowadays, one of the essential foundations in the manufacturing industry is undoubtedly industrial machineries and systems. The growing trends in productivity and efficiency of production as well as achieving international standards, particularly in the domestic and global competitive environments may not be imaginable without time management in Benchmarking: An International Journal Vol. 25 No. 7, 2018 pp. 2230-2247 © Emerald Publishing Limited 1463-5771 DOI 10.1108/BIJ-05-2016-0072 Received 26 May 2016 Revised 25 June 2017 Accepted 7 August 2017 The current issue and full text archive of this journal is available on Emerald Insight at: www.emeraldinsight.com/1463-5771.htm 2230 BIJ 25,7 application and operation of industrial machineries and production systems, and cost management in reducing maintenance expenditures and downtimes (Rostamiyan, 2006). Due to the advancement of technology in recent years, operation, maintenance and repair of machineries and systems, particularly in terms of technical protection and optimization of physical assets have gradually changed. Organizations are now more aware of the efficiency of technology in system failure prevention, because these failures can be a warning of production stop, loss of customers and reduction of market share, personnel unemployment, etc. According to Tavakkoli-Moghaddam et al. (2009), organizations are required to improve their understanding of an appropriate maintenance program and implement the program to remain competitive in the market. The literature shows organizations must consider that damages and downtimes of machineries and industrial installations are not an issue that can completely be prevented. However, less attention has been paid to developing planning techniques that can assure reliability across the value chain (Fraser et al., 2015). It is important because the lack of reliability in systems imposes pressure to organizations to improve overall business performance. For this reason, the relevant literature on maintenance emphasizes the utility of systems such as computerized maintenance management system (CMMS), reliability centered maintenance (RCM) and Total Productive Maintenance (TPM) may increase reliability (Fernandz et al., 2003). New trend of Maintenance activities is moving to a very complex environment known as repair engineering which requires organizations to look at the systems from a broader perspective. The main features of this trend is likely to be rapid expansion of outsourcing and requesting a broader cooperation from exploitation personnel, as discussed in the maintenance methods, TPM and implementation criteria. As discussed in the literature, it is projected that in near future, CMMS would undertake a greater role in the management of maintenance and repair activities in more effective and efficient ways (Garg and Deshmukh, 2006; Uysal and Tosun, 2012). In fact, the CMMS plays a fundamental role in solving the problem of huge amounts of data accumulated in the organization, although, due to the difficulties inherent in their structures, the use of this data is not always possible (Litprot and Palarchio, 2000). Homsi (1995) determined that a prerequisite for successful implementation of TPM is a CMMS to be utilized for managing maintenance information and implementing procedures of CMMS. Bohoris et al. (1995) discussed how Land-Rover as one of the leading companies in the UK utilizes TPM by implementing a CMMS. They found the implementation steps of TPM, the difficulties encountered, and the usefulness and necessity of a CMMS for the successful implementation of TPM in Land-Rover (Bohoris et al., 1995). Labib (2004) investigated the characteristics of CMMSs to identify their demands and current deficiencies in manufacturing industry. An implication was to identify the need for information to aid maintenance, followed by justifications for current deficiencies in existing off-the‐shelf CMMSs. Similarly, Ahuja and Khamba (2008) examined factors influencing the implementation of TPM practices in the Indian manufacturing industry, and to devise an overall maintenance strategy for overcoming obstacles to successful TPM implementation. Ying (2008) analyzed TPM and RCM synergic relationship using their benefits and barriers in a system and constructed the CMMS. An integrated system can combine the RCM analysis process, the situation of implementing TPM and the plant assets information together to attain the purpose of changing the maintenance strategy dynamically based on the plant’s operation condition. Rahim et al. (2014) examined the TPM as a significant technique to improve the maintenance management of production equipment. Also, they dealt with the relationship between TPM and existing techniques in maintenance management such as CMMS. Lopes et al. (2016) presented an ongoing project aiming to develop a CMMS for a manufacturing company and reviewed the requirements specification of a CMMS using a case study research. Further, they described the crucial phases of a project, including the 2231 Computerized maintenance management system identification of requirements and the specifications of the system, to show how the CMMS applied and reflected its effectiveness and efficiency (Lopes et al., 2016). The application of information technology certainly provides the possibility of optimizing preventive repair activities. Often, only after complementation of installation, users may understand that their new system does not fully meet their requirements. In fact, prospective users must be prepared to express what they expect from the CMMS, although they are not commonly able to evaluate an objectivejudgment and choose suitable software. This study attempts to fill this gap by proposing a conceptual model as how CMMS and relevant supportive organizational factors can affect the TPM. This study contributes to expand knowledge on the mentioned issue, as it has been neglected in previous research. More specifically, this study helps further research to look thoroughly at the implementation of CMMS in different contexts by identifying uncertain aspects of the CMMS and relevant supportive organizational factors and evaluating its relationship to the TPM. It is important because investigations on relationships among these three variables (CMMS, relevant supportive organizational factors and TPM) may reveal how an organization would rely on systematic and rigorous implementation of maintenance strategies to advance its organizational objectives and ensure competitiveness over the long term. 2. Theoretical framework 2.1 Computerized maintenance management system (CMMS) CMMS are using increasingly in control and maintenance management for machineries in servicing and producing in different industries. The principals of CMMS were used for the first time in the hospital maintenance systems in which machinery malfunction may have serious impacts of human life (Saharkhiz et al., 2012). Currently, companies consider the importance of maintenance management systems as a tool for enhancing the total performance in their systems (Enciso-Medina et al., 2011; Tätilä et al., 2014; Hooi and Leong, 2017). The emergence of smart devices in past few years has caused the popularity of these systems in different industries such as healthcare, automobile and aircraft (Shahin and Ghazifard, 2013; Tripathi and Tripathi, 2013; Irizarry et al., 2014). A CMMS is a software program designed to assist planning, management and administrative functions required for effective maintenance and repairs. Bagadia (2006) categorized these functions in production, planning and reporting work orders, developing record tracking and recording parts of transactions. According to Tretten and Karim (2014), a CMMS is not only a control tool of maintenance, but also, it is to ensure high quality of outputs by utilizing appropriate maintenance activities over time. Seemingly, one of the most significant benefits that a CMMS can provide for manufacturing industries is that it helps the organization to focus and investigate good repair experiences. Generally, the current CMMSs have been presented as modular configuration to ensure greater flexibility and good compatibility in various fields of production (Mather, 2003; Braglia et al., 2006). As the technical skills of maintenance and repair employees became better over time, the respect to such systems as an interesting option becomes more important. That is, investments on CMMSs in large and advanced organizations are increasingly growing. Technically, these systems are designed in a manner that provides significant support for documentations control through ISO 9001:2008 (Sivaram et al., 2012; Kedaria and Deshpande, 2014; Tretten and Karim, 2014). Many of the existing CMMSs have the same efficiency, and common components which are provided by many CMMS software applications (Saharkhiz et al., 2012). The application of a CMMS can create many advantages for an organization. One of the greatest benefits is to remove manual paper works and to monitor system activities leading to improved productivity (Ramachandra et al., 2012; Shahin and Ghazifard, 2013). It is noteworthy that the functionality of a CMMS is the ability to collect and store 2232 BIJ 25,7 customized information in the required form, as requested by the user (Uysal and Tosun, 2012). A CMMS does not assist for maintenance decisions, rather provides customized information for managers of operations systems to effectively influence service delivery and efficiently remain the system long-lasting. Generally, the advantages of the implementation of a CMMS can be seen as follows (Bagadia, 2006): • maintaining optimum device performance by reducing downtimes and resulting in a longer-lasting machinery; • diagnose the imminent problems rather than detecting the errors while happening, whereby resulting in less failures and customer complaints; • achieve a higher level of planned maintenance activities that allow more efficient use of personal resources; • influence enablers that better anticipate inventory management and purchase of spare parts for removing the deficiency and minimizing existing stocks; and • maintain optimum performance of the device by reducing downtimes and resulting in a longer lifetime of the device. 2.2 Relevant supportive organizational factors A critical review of previous studies on factors affecting the success of maintenance, repair and computerized systems shows five effective supportive organizational factors (Ang et al., 2001; Rouibah et al., 2009; Aref et al., 2013). These five factors include resource allocation, decision-making structure, senior management support, employees’ involvement and effective training. Each of these factors is briefly described below. 2.2.1 Resource allocation. One of the factors affecting the success of information systems is allocating sufficient resources. Ein-Dor and Segev (1978) suggested that resources such as money, qualified manpower and time are required for success in projects. Allocating adequate resources to information systems activities leads to an increase in organizational commitment and overwhelming organizational barriers (Beath, 1991). 2.2.2 Decision-making structure. Decision-making structure indicates the degree of control or authority to decide in the organization and the participation of employees in decision-making relating to the information systems (Hage and Aiken, 1969). A decentralized decision-making structure is one of the factors facilitating the implementation of IT systems in large and complex organizations (Boynton et al., 1994). Since the organizational structure establishes organizational processes and decision frameworks, a highly centralized organizational structure is likely to be more successful in the application of information systems (King and Sabherwal, 1992). Such justifications prove that the decision-making structure is a factor that affects the success of information systems. 2.2.3 Senior management support. Senior management support describes organization’s top-level managers’ participation in the information systems activities ( Jarvenpa and Ives, 1991). King and Teo (1996) acknowledged that senior management support facilitates the successful development of strategic information systems applications, while a lack of support prevents the strategic application of information systems. Similarly, Cho (2007) investigated the effect of leadership on the success of information systems and indicated that the leadership supports improved information systems in organizations through creating favorable circumstances and encouraging employees to use them at work. 2.2.4 Employees’ involvement. Organizations seek flexibility in response to a growing trend of the application of advanced technology at workplace. It is clear that organizations must consider employees’ involvement in decision-making processes as an essential way to 2233 Computerized maintenance management system acquire a broader knowledge at work to better identify and understand organizational requirements in information systems. Latham et al. (1994) claim that employees’ involvement has a motivational effect on their employees’ satisfaction and commitment, leading to an increase in their responsibility toward maintenance of the machineries that they work with and eventually resulting in continuous success of TPM in organizations. Similarly, a research by Ahuja and Khamba (2008) revealed that an increasing in employees’ involvement often leads to lower costs of procurement, maintenance and production and optimized layers of different business sectors of anorganization. 2.2.5 Effective instruction. There is no doubt that the effectiveness of instruction can improve the quality of information systems, but it requires complex situations for the organizations to meet significant changes rationally in accordance with adopting information systems to facilitate organizational achievements. However, organizations are required to consider the way that the applied instruction is needed to be prepared, implemented, analyzed and assessed, to increase its effectiveness and efficiency. Thiagarajan and Zairi (1997) contended that instruction is the second most important factor (after commitment) for the successful implementation of TPM in an organizational context. So, employees must be essentially trained for understanding the effective implementation of TPM. 2.3 Total productive management As a pioneer of total productive management in 1940s and 1950s, Japan strived to practically take advantage of theories and assumptions of preventive maintenance (PM) to optimize equipment maintenance systems through establishing Japanese culture with elements of teamwork, cooperation and responsibility, which was later known as the TPM approach (Ramesh et al., 2008). This innovative approach was rapidly globalized and consequently supported by industry owners (Sharma and Singh, 2015) to reduce costs of maintenance and increase functionality of systems (Figure 1). TPM is a program with focus on innovative methods of machinery maintenance and repair in the entire process. This program is developed to improve production, reduce production time and increase employee satisfaction (Fraser, 2014; Upadhye et al., 2009; Ramesh et al., 2008). Successful implementation of TPM in organizations is not only a subject to outlining the procedures and techniques required to implement it, but also it should also benefit from the intangible effects of TPM’s foundational philosophy such as good impression to customers about the company, its products’ quality and reliability (Ahmed et al., 2005). Kumar et al. (2014) examined the relationship between TPM program and manufacturing performance in the Indian manufacturing industries to: determine the benefits obtained from the TPM implementation; identify common indicators; and explore the common expectations of the system while implementing TPM program. This relationship is presented in coordination with management and employees’ involvement (see Figure 2). Solving software and employee problems is more difficult than applying TPM techniques, as human subjects in most cases require much time and more effort to be familiarized with and adopt the systems (Shirose, 1992; Tajiri and Gotoh, 1992). Run to failure PM developed TPM developed in Japan TPM brought to the USA TPM 19801970–19801960–19701950–19601940 Figure 1. Chronology of TPM 2234 BIJ 25,7 3. Hypotheses development and conceptual model 3.1 CMMS and TPM In contemporary highly challenging environment, CMMS plays a major role in the management information systems for competitiveness as it stores a large amount of data, information, previous maintenance cases and best practices including machinery track numbers, failure modes, diagnosis methods and maintenance solutions (Tajadod et al., 2016; Wan et al., 2017). Thus, achieving business productivity in maintenance systems must be treated as a strategic asset for industries to create world-class-manufacturers (Brah and Chong, 2004; Ahuja and Khamba, 2008; Ahuja, 2011). An organization’s performance in terms of TPM is significantly impacted by using appropriate information technology such as enterprise resource planning, manufacturing execution system, content management systems and CMMS ( Jonsson, 2000; Lai and Yik, 2012; Aboelmaged, 2014; Wan et al., 2017). In academic research, CMMSs have been investigated to manage information systems and knowledge and maintenance productivity (Stephens, 2010; Lopes et al., 2016; Fraser et al., 2015). For example, Rastegari andMobin (2016) indicated that a CMMS can support maintenance productivity by tracking the movement of spare parts, allowing operators to report faults faster; improve communication between operations and maintenance personnel more reliable; develop PM schedules on time; provide maintenance managers with information to have better control over their departments; and offer accountants information on machineries to enable capital expenditure decisions to be made. Investigating on a number of 558 companies that applied CMMSs, a research by Campbell et al. (2010) revealed that the studied companies, could improve their maintenance productivity up to 28.3 percent, reduce their equipment downtimes by 20.1 percent, save up to 19.4 percent of resources costs and reduce inventory maintenance and repair by 17.8 percent, in an average payback period of 14.5 months. The results of the study by Campbell et al. (2010), therefore, show the importance of the implementation of a CMMS in a maintenance productivity context. According to Fernandz et al. (2003), if a maintenance strategy is to be productive, it must be supported with CMMSs as a powerful tool necessary for obtaining information from raw data and supporting the decision-making process. Similarly, Bohoris et al. (1995) demonstrated the use of a CMMS can be an important contributor enabling a better organized TPM implementation by providing prompt and accurate information. Based on the relevant literature, hence, the following hypothesis is proposed: H1. A CMMS positively relates to the effectiveness of TPM. 3.2 Organizational factors and TPM Considering the literature discussed above, organizational factors, if applying appropriately, can provide many benefits for the TPM program (Mckone et al., 1999; Ahuja and Khamba, 2008; Abdallah, 2013). For example, Wang (2006) showed that organizational capabilities 1. System T P M 2. Measurement 3. Autonomous Maintenance 5. Continuous Improvement 6. Culture 7. Training 8. Plant Design4. Housekeeping Defined Objectives Source: Carannante et al. (1996) Figure 2. Eight strategic steps towards TPM 2235 Computerized maintenance management system can facilitate TPM practices across a variety of dimensions (total effectiveness, total maintenance system and total participation of all employees). It is thus understandable why many companies must develop organizational strategies as a source to facilitate obtaining and using TPM so that they can remain competitive (Singh and Ahuja, 2012; Méndez and Rodriguez, 2017). The existence of flexible decision-making structure along with the top management support, employees’ involvement, training and integrated maintenance strategies with total quality management, TPM practices can has a positive impact on the competitive position of companies and operational performance (Simões et al., 2011; Muchiri et al., 2014; Piechnicki et al., 2015; Modgil and Sharma, 2016). According to Poduval et al. (2015), TPM implementation will successful if employees stay motivated and committed. Based on a case study in plants in Germany, likewise, Konecny and Thun (2011) found that organizational supportive level has a positive impact on TPM. Based on these findings in the literature, hence the following hypothesis is proposed: H2. Related supportive organizational factors positively relate to the effectiveness of TPM. 3.3 Organizational factors and CMMSs A review of the previous studies shows that there exists a consensus that organizational factors are critical to the success of CMMSs (Marquez and Gupta, 2006; Aboelmaged, 2014; Lopes et al., 2016). Regarding the need for information to aid maintenance management, organization factors including resource allocation, decision-making structure, senior management support, employees’ involvement and effective training build up a link with CMMSs to offer simplified data collection and formalized modules for the analysis of maintenance data management (Labib, 2004; Rouibah et al., 2009; Aref et al., 2013). Organizationalfactors are a highly relevant issue in a production environment where the way how to manage a large number of machineries is so much critical and hence the need for achieving a CMMS is very significant (Marquez and Gupta, 2006). Empirical evidence relating to the maintenance systems supports that organizational framework is associated with CMMS in manufacturing organizations ( Jantunen et al., 2010; Uysal and Tosun, 2012). Testing the technological-organizational-environmental model, Aboelmaged (2014) concluded that e-maintenance technology readiness in manufacturing organizations are mainly influenced by technological and organizational determinants. With respects to the maintenance systems, Sacco (2014) emphasized the utilizing an appropriate organizational structure and implementing an effective training program may lead to a significant increase in sharing information across the organization and improving the overall CMMS performance. Therefore, the following hypothesis is proposed: H3. Related supportive organizational factors positively relate to CMMSs. Considering the aforementioned points and the factors affecting the TPM, we seek in this research to investigate the impact of these factors on TPM through developing a conceptual model (Figure 1), since the awareness of their impacts (organizational factors and CMMS) may contribute to better planning in order to improve the effectiveness of TPM in manufacturing systems (Figure 3). 4. Methodology 4.1 Sample and participants The data were collected from a sample of professional and skilled employees working in different manufacturing companies in Iran through distributing questionnaire through verbal, mail, fax and internet during January to March 2014. Approximately 206 of those working in manufacturing plants (60 companies) were invited to participate in the study. 2236 BIJ 25,7 Of the 206 distributed questionnaires, 133 questionnaires were returned. From them, 125 questionnaires were considered suitable and valid for data analysis. Also, confirmatory factor analysis (CFA) was used to confirm the construct validity of the questionnaire and results verified the validity of the questionnaire. Cronbach’s α was used to determine the reliability of the questionnaire. Table I shows the questionnaire’s variables, factor loadings and Cronbach’s α.

Reliability and validity analysis 2237 Computerized maintenance management system 4.2 Measures Data collection was done through a survey questionnaire with five-point Likert scales (Table AI). The items were identified by reviewing the relevant literature (Raouf et al., 1993; Rouibah et al., 2009; Cheng, 2011; Cuaa et al., 2001; Konecny and Thun, 2011; Amzat and Idris, 2012; Hazen et al., 2014), previously conducted empirical research and interviews with experts. A questionnaire was developed based on a review of theoretical foundations. The procedure of developing and implementing questions is at first based on customizing the items related to each variable. Considering the role of experts in management sciences, organizational behavior, industrial psychology and marketing, some items were also formulated in accordance with the atmosphere of Iran’s manufacturing companies. In doing so, a primary copy of the questionnaire was distributed among a sample of 30 production experts and necessary modifications were made based on their comments. Figure 4 illustrates the research methodology used in this study. Finally, after distributing and collecting the questionnaires, the obtained data were analyzed using SPSS18 and Amos20 software. Structural equation modeling (SEM) was used to validate the conceptual model and test the hypotheses. In SEM, the adaptation of the research data and the conceptual model is investigated to see if the fit is good and, on the other hand, to test the significance of the relationships in the fitted model.

Research methodology 2238 BIJ 25,7 5. Findings Following the two-step approach recommended by Anderson and Gerbing (1988), we first examined the measurement model to test reliability and validity. Then we examined the structural model to test research hypotheses and model fitness. First, we conducted a CFA to examine the convergent validity and discriminant validity. To determine the extent to which the indices are acceptable for measurement models, all measurement models must be separately analyzed at first. In doing so, three measurement models which were related to the variables are separately tested. The total fit indices of measurement models are presented in Table II. According to Table II, it can be concluded that the measurement models are totally fit. In other words, general indices verify that the data clearly supports the models. After reviewing and confirming the measurement models in the first step, the fit of the research conceptual model was tested in the second step. Total fitness indices of the conceptual model are presented in Table III. As shown in Table III, all indices were consistent with the acceptable fit level. So, it can be concluded that this model fits well with the data, and hence, the conceptual model can be considered for hypotheses analysis (see Figure 5).

Total fitness indices of the survey 2239 Computerized maintenance management system After reviewing and approving the model, the two partial indices of critical ratio (CR) and p were used to test the significance of the hypotheses. CR is a value which is obtained by dividing the “estimation of regression weight” by “standard error.” According to a significant level of 0.95, the CR must be out of (−1.96, +1.96). If a CR is inside this interval, the parameter of the model is not considered as a significant ratio. The hypotheses with regression coefficients and the values of partial indices of each hypothesis are presented in Table IV. As seen in Table IV, with respect to the absolute value of the critical ratios which are greater than 1.96 and the p-values which are less than 0.01, the regression coefficients are impressive and support the research hypotheses. Of the three hypotheses, all have positive impacts. The results obtained from AMOS20 software showed that the structural model of the research has a good fit and the overall fit of the model is acceptable (CMIN/df¼ 2.25, RMSEA¼ 0.032, GFI¼ 0.97, AGFI¼ 0.95 and CFI¼ 0.98). All measured path coefficients have significant values (po0.001). Reviewing the literature and previously conducted studies confirmed the results to be expectable, with positive and significant relationships between organizational factors and direct CMMSand TPM. As indicated in Table IV, the relationship between CMMS and TPM is significant ( β¼ 0.66, CR¼ 5.41). This finding supports H1. CMMS is a computerized maintenance management tool. This tool is used to enter, approve and plan the information about the maintenance and repair activities and the related costs and times. In fact, the main task of a CMMS is provision and this system is a tool for managing and improving maintenance and repair activities for equipment, facilities and machines in organizations. As a result, methods and criteria should be defined to evaluate the personnel’s skills and their participation in different branches of TPM so as to encourage those with higher levels of skill and participation. Additionally, the effects of organizational factors on TPM is positive and significant ( β¼ 0.52, CR¼ 4.73). These finding indicates that H2 is supported. Thus, an environment should be provided in which the personnel are courageous to participate in maintenance activities and needed supports are done by maintenance groups. The personnel should have the ability to identify partial defects and remove them, and the organization should let them comment on defects identification and analysis. Finally, the path coefficient from organizational factors to CMMS is positive and significant (β¼ 0.54, CR¼ 5.06). According to these finding, H3 is supported. In this regard, company’s managers help reduce costs through supporting the CMMS which finally increases the company’s ability to compete with its rivals. Also, implementing a CMMS in a company collects the produced knowledge effectively and helps increase human resource efficiency which in turn indirectly reinforces the company’s competing power against other competitors. 6. Discussion and conclusion This study aimed at developing and validating a conceptual model on relationships among CMMSs and relevant supportive organizational factors and TPM. More specifically, Hypothesis Path β CR Result H1 CMMS → TPM 0.66*** 5.41 Supported H2 OF → TPM 0.52*** 4.73 Supported H3 OF → CMMS 0.54*** 5.06 Supported Note: ***po0.001 Table IV. Regression coefficients and results of hypotheses test 2240 BIJ 25,7 result of H1 indicated that the principle of CMMSs can positively relate to the effectiveness of TPM. This result is in line with research by Rastegari and Mobin (2016) and Campbell et al. (2010). Similar to the research of Rastegari and Mobin (2016), our finding in H1 showed that assist planning, management and administrative functions can develop PM schedules and offer real time PM schedules to better identify malfunctions across the systems. H2 indicating the relationship between supportive organizational factors and the effectiveness of TPM was also supported. Consistent with research by Poduval et al. (2015) and Konecny and Thun (2011), our finding for H2 illustrated that organizations must utilize a flexible decision-making framework through participation of both top management and employees to ensure integration across the system and identify potential risks prior to happening. These risks are important as they may increase the system costs over time. Similarly, H3 was supported in which its finding showed that supportive organizational factors are related to CMMSs. In line with research by Aboelmaged (2014), Jantunen et al. (2010) and Uysal and Tosun (2012) that highlighted technological factors applied across the organization can facilitate implementing the integrated maintenance strategies and allow both management and employees to establish an appropriate decision-making process for the purpose of the analysis of maintenance data management, our finding also showed that this relationship can help simplify data collection, application and sharing across the systems to ensure system reliability in data analysis. While the application of CMMS and TPM has been considered as an important management principle that can provide strategic and operational benefits, adoption of these techniques has yet to be seen as a considerable rate in manufacturing companies. Thus, it is necessary to find out about the effectiveness of applying CMMS and related supportive organizational factors on the effectiveness of TPM so as to create a positive attitude toward these principles in operational performance of an organization. Building upon this theoretical objective, this study has enhanced and developed a research model to test the impact of related supportive organizational factors on CMMS and TPM in manufacturing companies in Iran. The current study’s framework provides a good starting point for analyzing and investigating appropriate factors that may affect the performance of manufacturing industry thereby, in comparison with previous research, this study developed a unified integrated model that evaluate the relationships between CMMSs, related supportive organizational factors and the effectiveness of TPM. Many organizations receive services from domestic and external environment producing software applications for automation of their business processes which may dissatisfy them from these services in majority of cases. The main reason for this dissatisfaction is because of a lack of appropriate evaluation and analysis regarding the related processes and investigation of requirements for the automation, as well as, a lack of software evaluation in order to find out the way in which they can fulfill the identified requirements. In fact, the effectiveness of these software applications is supported by organizational factors including allocating the resources, senior management support and the organizational culture and structure. 6.1 Managerial implications This study offers several managerial implications. First, the use of principle of CMMSs in manufacturing organizations may reduce maintenance costs. Top management is therefore, required to ensure all resources such as human capital, social capital and financial capital are considered prior to establishing a CMMS. Managers must consider the role of employees in achieving a CMMS. In this case, organizational trainings and interventions may help better prepare employees to adopt the principle of a CMMS. This in turn needs financial support in which all machineries should be evaluated for maintenance and possible repair in both short and long term. Second, managers are required to immediately look forward to seeing how to increase the organizational 2241 Computerized maintenance management system productivity as the application of a CMMS requests so much financial support over time. As a result of this, third, management would be able to improve the industrial average savings resulting from the initiation of a functional predictive maintenance program: reduced the number of errors, reduced downtime, increased service life and availability of components, preventive remedies, reduced expenditures of the parts and workforces, integrated technical diagnostics in maintenance management, improved product quality, improved safety of workforces and working environment, increased employee self-esteem in decision making, increased energy savings. The present study may help the maintenance managers or line managers on shop floor to understand the various aspects of organizational factors, CMMS and, consequently, how do they affect the TPM practices. Effective CMMS and TPM help to make an eye on the day to day operations processes and its maintenance requirements for business excellence. 6.2 Limitations and research directions Since the objectives of the present study have been accomplished, it is required to state its limitations. First, the study has mostly focused on medium- and high-tech industries. So, the results cannot be generalized for low-tech industries, because challenges and effective factors in low-tech businesses are different. Second, the study has only considered manufacturing companies in Iran. Therefore, it is necessary to study multinational companies and expand the research scopeto include more international partners. Third, the information required for the study has been collected during the growth step of applying CMMS and TPM. As these principles are accepted more extensively, following the effect of their applications on the effectiveness of the organization will be more rational. In addition, all the data have been collected cross-sectional, thus the variables and their results may be limited to a specific period. Future research may follow the progress of consequences of applying CMMS and related supportive organizational factors from the growth to maturation. We recommend further research to investigate the effects of applying the RFID technology on the effectiveness of TPM and performance in manufacturing sectors, as we believe that technological innovations can facilitate the adoption of CMMS and TPM in an organizational context. Despite the methodological perspective in this study consists of a quantitative approach, we would expect a significant tendency toward applying qualitative research methods in this field, as the role of human resources and/or social capital may be sooner or later seen as an enabler of TPM.
