Respondents were the employees of 62 manufacturing firms of Thailand whom opinion has been taken through structured questionnaire. SPSS and AMOS are used to analyze the data through confirmatory factor analysis and structural equation modeling. Results have affirmed that IOT capability can enhance sustainability performance while all three dimensions of IOT enabled supply chain integration have shown significant positive mediating role in the relationship between IOT capability and sustainability performance. This study is unique due to its novel outcome of sustainability performance which was not previously tested with IOT capability. The results have implications not only for manufacturing sector but can also facilitate policy making too. Key Words: Internet of Things, IOT Capability, Supplier Integration, Customer Integration, Internal Integration and Sustainability Performance 1. Introduction Performance of a firm does not merely depend on its efficiency, but also on the market where it operates. Performance is the basic tool of knowing how well a company is doing or how adverse is its condition [1].
