Developing a performance measurement system for apparel sector lean manufacturing organizations in Sri Lanka
(2015-09-01) Perera, PST; Perera, HSC; uom.lk, HSCP
Performance measurements systems were rarely adapted to changing manufacturing environments. Lean is one such practice aiming at productivity improvements. Non-cost performance improvements resulting from lean makes the inadequacy of traditional measurements for evaluating performance. Sri Lankan apparel manufacturers adapt lean manufacturing to meet global business challenges. However a study has not been done to develop an appropriate performance measurement system for lean environment in Sri Lankan apparel sector lean practicing companies. This study develops such a model from literature review and interview. Finally it is validated with the existing models.

Environmental performance evaluation in supply chain
(2015-09-01) Perera, PST; Perera, HSC; Wijesinghe, TM
Environmental performance evaluation is an area of growing concern among the worldwide community. Consequently, measurements to evaluate environmental performance are of great importance. However, lack of a quantifiable model to study the environmental performance is a problem in this area. This study therefore attempts to quantify the environmental performance of supply chain of a manufacturing company, which requires evaluation of many criteria. Therefore, selection of environmental performance measures leads to a multi-criteria decision making problem. As a result, analytical hierarchy process is selected to develop the model and is solved with Expert Choice software. Finally the proposed model is applied to a case study company to identify the key areas of environmental performance of the company’s supply chain and to assess various product categories manufactured under those key areas.

Factors affecting effective lean implementation: a case study of a tyre manufacturing company in Sri Lanka
(2010) Perera, HSC; Perera, PST; Raveendra, LM
The lean manufacturing system is an integrated set of principles, practices, tools, and techniques which addresses the root causes of the operational problems. It ensures that the customer receives the product with required quality, price, and delivery performance while maximizing company's competitive advantage and shareholder value When lean system is successfully implemented production will he run smoothly without huge inventory. It was found that the companies had not reaped the expected benefits by implementing lean all the times. Studies reveal that the benefits are limited by the environmental context and the organizational contingencies. Therefore this study focuses on identifying the factors affecting the lean implementation using case study approach A conceptual model was developed from the facts drawn from the literature and it was tested with a manufacturing organization which had implemented the lean concept. Core team members who directly involved during the implementation process were interviewed. A questionnaire was designed based on the information gathered from the core team members and the literature It was distributed among 100 executives to collect data. They were randomly selected from those who participated in lean implementation process. Principal component analysis and descriptive statistics were used to analyze data using Statistical Package for Social Sciences (SPSS'). Results disclosed the factors which drove the lean implementation process and those that prevent effective implementation. I he outcome of this study would help other

Impact of business process reengineering and customization success enterprise resource planning implementation
(2016-10-05) Perera, HSC; Perera, PST; Gunawardhane, MKS
Enterprise Resource Planning (ERP) systems which are developed based on the industry best practices integrate all the business functions of an organization. Reduction of operating costs, efficiency improvements, and processes standardization are the benefits expected by ERP. However, some business managers question these benefits as they have bad experiences with ERP implementation. As a result, governing factors of ERP implementation have been investigated by many researchers. It was identified that ERP customization and resistance to change required by Business Process Reengineering (BPR) as major influencing factors. Thus this study investigated how BPR and customization involved during the implementation process affected the expected outcome of ERP system. The study adopted quantitative methodology with survey approach. Conceptual model was developed and variables were operationalized from the literature. Customers of ERP systems of SAP and IFS were taken as the target population and sample was drawn using stratified random sampling method. questionnaire was used for data collection. Face validity of the questionnaire was checked with experts’ opinion. It was e-mailed to a key person involved in the ERP implementation of each company. Descriptive and inferential statistics were used for data analysis. It was found that interdepartmental integration, end- to- end information tracking, up- to- date information, speed up transactions, and cost reduction as the major expectations of the companies to implement ERP. However achievement to expectation ratio of perceived benefits was poor. Organizations experienced higher level of customization and lower level of BPR during ERP implementation process. BPR was positively and customization were negatively correlated to the perceived benefits. Therefore companies should implement BPR along with ERP project and adapt to ERP practices rather than customizing it.
