There are five generic process framework activities: 1. A software process model is an abstract representation of a software process. In this section a number of general process models are introduced and they are presented from an architectural viewpoint. In this phase, requirements are gathered from the customer who wants to develop the software. Iteration, which was taken to subsume 'backtracking', 'rework', 'repetition' and so on, seems to be central to the software process; selecting it as a main topic allowed intensive consideration of many of the key problems that face software engineering. Writing code in comment? When you work with an Iterative Development model, the starting point doesn’t need a full requirements specification. After getting the requirements, the system analyst analyses the requirements that whether the requirement can be fulfilled or not. Data objects and attributes are identified, and existing data structure are reviewed for quality. This is an attempt to translate a set of requirements and program/data models that were laid down in the “ requirements document ” into a well designed and engineering software solution. Explain what a software is and describe the software engineering layers. Hence, the product got ready step by step.
