Concurrent engineering is a product development approach which requires collaborative multidisciplinary team environment with effective communication. The nature of approach determines the information needs of the project team. The flow of information can be of various types such as Sequential, Partial Overlap, Parallel, and Coupled. Among these types, Coupled is the more realistic process of simultaneous engineering, where information transfer is essential and involves iteration. Concurrent engineering involves free flow of information among team members and vague or partial information helps for follow up and overlapping tasks.The states of evolving information are: null, vague, partial and complete. As vague or partial information can represent valuable orientation for overlapping tasks, it is very essential to represent this state of information. None of the existing models have any room to represent the states of such information.This paper reports a detailed study on existing methodologies related to data quality and comparison of the methodologies. |
