“Explain the software process and different models involved in this process.” This is MI0024 SMU MBA question assignment. The question has been taken from Software Engineering for Information System (IS) of SMU MBA MI0024. I have decided to write the assignment question after Branch and Bound Technique to solve an I.P.P. problem.
In the recent years, there has been a significant emphasis on “process maturity.” 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 SEI uses an assessment that results in a five point grading scheme.
To solve actual problems is an industry setting, a software engineer or a team of engineers must incorporate a development strategy that encompasses the process, methods, and tools layers. 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.
This problem solving loop applies to software engineering work at many different levels of resolution. It can be used at the macro level when the entire application is considered, at a mid-level when program components are being engineered and even at the line of code level.
Software Process Models:
The Linear Sequential Model: Sometimes called the classic life cycle or the waterfall model, the linear sequential model suggest a systematic, sequential approach to software development that begins at the system level and progress through analysis, design, coding, testing and support.
The Prototyping Model: Often, a customer defines a set of general objectives for software but does not identify detailed input, processing, or output requirements.
The Incremental Model: The incremental model combines elements of the linear sequential model with the iterative philosophy of prototyping.
The Spiral Model: The spiral model, originally proposed by Boehm [BOE88], is an evolutionary software process model that couples the iterative nature of prototyping with the controlled and systematic aspects of the linear sequential model.
The RAD Model: Rapid application development (RAD) is an incremental software development process model that emphasizes an extremely short development cycle.
The intent of software engineering is to provide a framework for building software with higher quality. Software engineering is a discipline that integrates process, methods and tools for the development of computer software.
