What is the importance of Process Model in development of Software System? Explain Prototype Process Model.
Importance of Process Model
The process model is the abstract representation of process.
Also known as Software development life cycle (SDLC) or Application development life cycle Models
Process models prescribe a distinct set of activities, actions, tasks and milestones (deliverables) required to engineer high quality software.
Process models are not perfect, but provide roadmap for software engineering work.
Software models provide stability, control and organization to a process that if not managed can easily get out of control.
Software process models are adapted (adjusted) to meet the needs of software engineers and managers for a specific project.
Prototype process model
Prototyping model is appropriate when
Customers have general objectives of software but do not have detailed requirements for functions & features.
Developers are not sure about efficiency of an algorithm & technical feasibilities.
It serves as a mechanism for identifying software requirements.
Prototype can be serve as “the first system”.
Both stakeholders and software engineers like prototyping model
Users get feel for the actual system
Developers get to build something immediately
It works as follow
Communicate with stockholders & define objective of Software
Identify requirements & design quick plan
Model a quick design (focuses on visible part of software)
Construct Prototype & deploy
Stakeholders evaluate this prototype and provides feedback
Iteration occurs and prototype is tuned based on feedback
Problem Areas
Customer demand that “a few fixes” be applied to make the prototype a working product, due to that software quality suffers as a result
Developer often makes implementation in order to get a prototype working quickly; without considering other factors in mind like OS, Programming language, etc.
Advantages
Users are actively involved in the development
Since in this methodology a working model of the system is provided, the users get a better understanding of the system being developed
Errors can be detected much earlier
