Gap analysis in supplier sustainable development-with a case study in healthcare service

Abstract

The objectives of this study are threefold: to identify the three factors of supplier sustainability; to calculate the gap ratio of the three factors; and to prioritise the gaps in terms of their importance ratings. For this purpose, a healthcare service supplier has been investigated as a case study. Base on literature review, the indicators of the three factors of supplier sustainability of healthcare service have been identified and confirmed using content validity analysis. Then, by calculating the expectation and perception of indicators, the gap of the three factors of supplier sustainability has been computed and finally, the gaps have been prioritised in terms of their importance ratings. Findings indicated that the supplier under study had a negative gap in all of the indicators of the three factors of sustainability and its highest and lowest gaps were related to the economic and environmental factors, respectively. © 2020 Inderscience Enterprises Ltd.
