    Technology Assessment of Herbal Products Industry in Sri Lanka
    (SSRN, 2021-06-29) Silva, N; Perera, H. S. C; Perera, L. C. D.T
    Production of herbal product is not only a local business but also has global market opportunities. Therefore manufacturing with proven quality and consistency is an important aspect. The manufacturers should gain technological competence to ensure authenticity and efficacy, complying the quality and safety regulations, enhanced productivity and efficiency. In the competitive market environment technology assessment is a tool which can be used in projecting future trajectories of technology as well as current performance level of the organization. Out of the available models and frameworks for technological assessments, this study has used inputs from two models namely, the Technology Audit Model by Garcea – Areola and Outline of Innovation Management Audit by Tidd et al. these inputs have been used to develop a single model that can be effectively adaptable to herbal products industry. There are two main objectives of the study. Firstly, develop a model which includes guide lines for technology assessment of the herbal products industry in Sri Lanka. Secondly, assessment of the level of technology position of LNP Ltd using the model and presenting recommendations for future improvements. To accomplish the objectives, the study has identified five broad areas of technology, namely Technological Environment, Technological Strategy, Innovations and Technology Development, Technology Component and Technology Transfer, against which the LNP Ltd has been analyzed. A check sheet to cover these elements has been used to guide through the assessment process. The elements using a three of the point scale ranging from High to Low (High -3, Low-1). The score of 3 for each element will represent the industry standard practice against which the other practices are measured.

    Factors affecting successful implementation of lean manufacturing tools and techniques in the apparel industry in Sri Lanka
    (SSRN, 2011-04-27) Silva, N; Perera, H. S. C; Samarasinghe, D
    Lean Manufacturing is a business strategy which was originated and developed in Toyota Motor Company, Japan. It is useful in identifying waste associated with processes. As a result companies can improve their productivity and quality and can achieve a competitive advantage over others. Lean Manufacturing was originated in automotive industry and then later on spread to many other industries in both developed and developing countries. In implementing this concept Toyota has introduced and developed many tools and techniques which can be used effectively. In Sri Lanka, apparel sector is the leader in implementing Lean Manufacturing. However a little research work is carried out in regarding its suitability. Therefore in order to fill this empirical gap, this research is an attempt to identify factors such as suitable methods of implementation, order of implementation, challenges, how to overcome those challenges and benefits of implementing Lean Manufacturing concepts in the apparel sector of Sri Lanka. The study first undertook literature review in the field of Lean Manufacturing. Then it developed broader research questions and administered them to fifteen apparel manufacturers in Sri Lanka using personal interviews and observations methods. The sample firms were selected judgmentally. In analyzing the data descriptive statistics and qualitative techniques were used. The result of the study revealed factors such as implementation strategies, order of implementation, challenges, how to overcome those challenges and benefits have influenced the successful implementation of Lean Manufacturing in mass production apparel industry. Since Lean is new to most of the Sri Lankan apparel manufacturers, the full benefit is not yet achieved. But current situation suggests that the industry can go forward with Lean.
