To understand the current state, health and efficiency of an organization, evaluation based on an organizational diagnostic model are vital. There have been a number of framework and models developed for this purpose which serves as a general rule, but they lack accuracy in certain industries due to its characteristics and scope. This paper critically analyzes previous models, highlighting its definition, advantages, disadvantages, applications and comparison between them. Recognizing factors that contribute to the performance of construction/engineering companies, the authors propose a new diagnostic model which is more suited to this industry. The new diagnostic model addresses issues of culture at work while redefining the scope of every pillar involved in previous diagnostic models. It is a revelation of an evaluation platform for all companies within the same industry, which allow further studies on sustainability framework to be developed on top of this platform.
