• Software process maturity is the extent to which a specific process is explicitly defined, managed, measured, controlled, and effective • Prescriptive Process Models Process Models - Generic process framework (revisited) - Traditional process models - Specialized process models - The unified process Since a working model of the system is displayed, the users get a better understanding of the system being developed. The feedback is collected in an organized manner and used for further enhancements in the product under development. A software process model is an abstract representation of a process that presents a description of a process from some particular perspective. The changes accepted are again incorporated in the new Prototype developed and the cycle repeats until the customer expectations are met. Confusing or difficult functions can be identified. Some examples of the types of software process models that may be produced are: 1. It can also be defined as a simplified representation of a software process. A software assessment (or audit) can be of three types. This includes the initial development of software and its maintenance and updates, till desired software product … Specialized process model There are 4 types of Specialized process model : 1.5 SPECIALIZED PROCESS MODELS. Waterfall Incremental Spiral Discuss the chief programming team approach. A Vertical prototype on the other side is a detailed elaboration of a specific function or a sub system in the product. To accomplish this task agility is required. First, a basic prototype with all the existing pages is presented in the HTML format. A software process model is a specified definition of a software process, which is presented from a particular perspective. Any software process must include the following four activities: 1. For example, the assessment team must be led by an authorized SEI Lead Assessor. To overcome these drawbacks of Waterfall model, in the mid-1990s the Agile Software Development model was proposed. Software prototyping is used in typical cases and the decision should be taken very carefully so that the efforts spent in building the prototype add considerable value to the final software developed. During specification, more knowledge about the problem may be required which can again trigger the elicitation process. This type of prototyping uses very little efforts with minimum requirement analysis to build a prototype. Software Process, Perspective and Specialized Process Models: One of the primary duties of the manager of a software development project is to ensure that all of the project activities follow a certain predefined process, i.e. The advantages of the Prototyping Model are as follows −. The SDLC aims to Software Evolution The process of developing a software product using software engineering principles and methods is referred to as Software Evolution. These activities may involve the development of the software from the scratch, or, modifying an existing system. Prototypes can have horizontal or vertical dimensions. Each process model follows a Series of steps unique to its type to ensure success in the process of software development. When the assessment target is the organization, the results of a process assessment may differ, even on successive applications of the same method. Evolutionary model is a combination of Iterative and Incremental model of software development life cycle. Software project management has wider scope than software engineering process as it involves communication, pre and post delivery support etc. Vertical prototypes are technical in nature and are used to get details of the exact functioning of the sub systems. A software process assessment is a disciplined examination of the software processes used by an organization, based on a process model. Software process models have been developed since 1968. Then thereafter many successive iterations/ versions are implemented and delivered to the customer until the desired system is realized. These builds are provided in iterations. They … It consists of three sequential phases. While, the workarounds are used to give the same look and feel to the customer in the prototype developed. A software process model is an abstraction of the actual process, which is being described. Software Processes is a coherent set of activities for specifying, designing, implementing and testing software systems. READ MORE on www.tutorialspoint.com Software Engineering — Software Process and Software Process Models (Part 2) Here the degree of implementation and their effectiveness as substantiated by project data are assessed. A project’s quality, timeframes, budget, and ability to meet the stakeholders’ expectations largely depend on the chosen model. Each process model follows a Series of steps unique to its type to ensure success. At least, one team member must be from the organization being assessed, and all team members must complete the SEI's Introduction to the CMM course (or its equivalent) and the SEI's CBA IPI team training course. Incremental prototyping refers to building multiple functional prototypes of the various sub-systems and then integrating all the available prototypes to form a complete system. Process maturity becomes relevant when an organization intends to embark on an overall long-term improvement strategy. Software project assessments should be independent assessments in order to be objective. This means that any phase in the development process begins only if the previous phase is complete.
