(Emerald Publishing, 2022-12-01) Kendangamuwa, J.K; Senanayake, T.V; Jayasundara, I.H; Botheju, I.U; Madhavika, W.D.N; Weerarathna, R.S
This study primarily looks at how operation flexibility focused capability impacts supply chain risks in the Sri Lankan courier sector in the industry 4.0. This is meant to measure both the good and bad effects that operation flexibility focused capability has had on Sri Lankan courier companies. This research gives the reader, some important information and ideas that they can use to reduce any negative effects or improve their ability to innovate in logistics. Also, this study will look into a number of ways to reduce supply chain risks caused by operation flexibility focused capability. This research paper discusses about how operation flexibility focused capability impacts on the company side, risks on the customer side, and the environment side risks. Also, based on the research model and hypothesis, researchers estimated that operation flexibility focused capability has a statistically significant effect on company side risks, customer side risks, and environmental side risks. A thorough review of the literature and a questionnaire survey with managers and executives in the Sri Lankan courier industry were used to collect data for the research paper. A sample population of 60 courier companies were selected from the Registrar of companies and based on the morgan’s table, 52 courier companies were selected as the sample size. Simple random sampling was used as the sampling technique to derive the sample size. Smart PLS (Partial Least Square Method) version 4 was used to validate the sample data collected for the research paper through an empirical analysis of the questionnaire survey data.

The misleading fallacy of, higher the chemical fertilizer higher the yield therefore, better the income be. Have triggered in an over usage of chemical fertilizer more than the recommend standard. This has created in a self-pressuring situation among farmers in developing countries. This vulnerability occasionally leads into a decision-making situation where both life and death are seen as viable options. Hence in order to safeguard the farmer, with the aims of educating these disobedient farmers, through the process of validating the existing chemical fertilizer standard. This research was carried forth in Sri Lanka, for the paddy farmer. The data were collected in a data triangulation, where a controlled experiment, two series of interviews and two sets of questioners were utilized. Both, quantitative as well as qualitative data and, primary as well as secondary data were collected. Depending on the nature of the data collection instrument, an experiment, thematic, descriptive and a correlation analysis were performed through statistical software applications. Further, a yield and a soil test was performed for the controlled experiment plots. By adjusting the parameters accordingly, this study could be used as a model by other countries, regions or crops. Finally concluding on a policy implication, to eliminate or reducing the chemical fertilizer over usage in developing countries. Further avenues for a managerial implication where the Balance of Payment could be used to positively stimulating a developing countries Gross Domestic Product to achieve sustainable economic growth in the long run are discussed.

Sustainable Supply Chains of Sri Lankan Manufacturing Organizations: A Study on Operational Excellence Models During the COVID-19 Pandemic
(researchgate.net, 2022) Nagendrakumar, N; Malsinghe, M.T.D; Gunathilaka, M.H.A; Bandara, I.P.C.D; Wijerathne, A.I; Madhavika, W.D.N
This paper presents an investigation on operational excellence (OpX) models of sustainable supply chains (SSCs) in Sri Lankan manufacturing organizations during Covid-19 pandemic. This investigation consists of multiple case studies of Sri Lankan manufacturing organizations in following industries: rubber and plastic products, wearing apparels, paper and paper products. Based on a pre-existing OpX model, six Critical Success Factors (CSFs) were identified in terms of SSCs. This research was conducted as an exploratory case study where data is collected through in-depth interviews, company websites/reports. By using a deductive approach, findings of CSFs effecting behaviour of OpX models are displayed. Thematic and Content analysis on the behavior of OpX models in SSCs are non-generalizable beyond this research. The findings display the organization in respect to wearing apparels has a more sustainable approach to better manage their OpX model and more strategic Upper Echelons to gain better strategic outcomes before/during Covid-19 pandemic. The profile of a manager was vital in interpreting OpX models in their organizations. The study outcomes can inform organizations to prime their OpX model for a crisis of Covid-19 magnitude. The effects may be generalized further to other industries. The study describes connectivity of Upper Echelons Theory to OpX models and contributes to literature through a demonstration of CSF behaviours in OpX models of SSCs during the Covid-19 crisis.
