The Triangular Life Cycle Model

  • Phil Robinson
Conference paper
Part of the Communications in Computer and Information Science book series (CCIS, volume 55)


The waterfall life cycle model suffers from a number of problems but in spite of this, it continues to be the most widely used life cycle model. A different life cycle approach is proposed that emphasizes the product life cycle rather than the project life cycle, quality management priorities rather than project management priorities and views of quality rather than views of the project schedule. A quality management tool based on different views of quality is used to identify the “gaps” that inevitably exist between a user’s needs, the requirements specification and the product that is delivered. This is followed by a brief discussion of how these “gaps” can be closed.
