RAD Model Rapid Application Development (RAD) is an incremental software development process model which is a “high-speed” adaptation of the linear sequential model in which rapid development is achieved by using component-based construction. If requirements are well understood and project scope is constrained, the RAD process enables a development team to create a “fully functional …

Evolutionary Software Process Mode: Evolutionary software models are iterative. They are characterized in manner that enables the software engineers to develop increasingly more complete version of a software. That is, initially a rapid version of the product is being developed and then the product is developed to more accurate version with the help of the …

Prototyping Model Often, a customer defines a set of general objectives for software but does not identify detailed input, processing, or output requirements. In other cases, the developer may be unsure of the efficiency of an algorithm, the adaptability of an operating system, or the form that human/machine interaction should take. In these, and many …

Linear Sequential Model/Waterfall Model/Classic Life Cycle The linear sequential model, sometimes called the classic life cycle or the waterfall model, suggests a systematic, sequential approach to software development that begins at the system level and progresses through communication, planning, modeling, construction and deployment. The following given figure illustrates the linear sequential model for software engineering. …

Problem Solving Loop : All software development can be characterized as a problem solving loop in which four distinct stages are encountered: status quo, problem definition, technical development, and solution integration.             Status quo represents the current state of affairs, problem definition identifies the specific problem to be solved, technical development …

Software Process Model :  To solve actual problems in an industry setting, a software engineer or a team of engineers must incorporate a development strategy that encompasses the process, methods, and tools layers and the generic phases.  This strategy is often referred to as a process model. A process model for software engineering is chosen …

CMMI (The Capability Maturity Model Integration):  The Software Engineering Institute (SEI) has developed a comprehensive model predicated on a set of software engineering capabilities that should be present as organizations reach different  levels of process maturity. To determine an organization’s current state of process maturity the CMMI uses two ways, (i) as a continuous model …

Software Process:  Process defines a framework for a set of Key Process Areas (KPAs) that must be established for effective delivery of software engineering technology. This establishes the context in which technical methods are applied, work products such as models, documents, data, reports, forms, etc. are produced, milestones are established, quality is ensured, and change …

The work associated with software engineering can be categorized into three generic phases, regardless of application area, project size, or complexity. Following flowchart encompasses the phases. Three Phases of the Generic View of Software Engineering: 01. Definition Phase:  The definition phase focuses on “what”. That is, during definition, the software engineer attempts to identify what …
