In order to be competitive through globalisation and free trade agreements, Small Manufacturing Enterprises must provide a high quality products at a competitive price at the right time. But inadequate resources of the enterprises have prevented them to remain competitive. Therefore they need to innovate and find new ways to overcome these challenges. Collaborative Manufacturing Network (CMN) is a way forward to address these challenges. However, the process of collaboration is not a simple process. Instead, it is a complex and very dynamic process since there are many factors involved that need to be considered for the establishment of a successful collaboration. Many researches have been conducted in this area of CMN, but there are still numerous unsolved problems identified. Decision making issues and formulating business collaboration model in a context of CMN are two such issues. This research tries to identify the problems faced in a CMN environment, stress on the importance of building a model based on the consideration of aspects involved in a CMN and then identifying model for decision making process in a CMN Environment.
