The software process model plays a key role in software development some of the key roles are given below.
Complete Planning
Software process models provide the complete planning for the software project. A big project requires more efficient planning for making the project successful likewise small projects also require planning but if at the start of the project you made a mistake and miss any prerequisites then your project will require two to three times of revisions the worst part of development.
Define complete the project scope
The software process model defines the complete project scope. In the Requirement Engineering process defining the project, the scope is very much important because if you define the scope of the project poorly or incompletely scope your project led to unsuccessful.
Effective Team leadership
The software process model defines the different steps of the software development process in each step different teams work to gather for the successful delivery of the project. In software development the if project leader is ineffective and poorly manages the project improperly defines the iteration of completion of the project is unsuccessful and useless at the end of the project.
Successfully identify the assumptions
In software development, if you failed to define the assumption about the project then your project in the end will be useless.
Example:
The project will work on Android Based Mobile Technology
The project will work in presence of Wi-Fi, 3G, or 4G technology.
Tracking the project progress.
Software process models provide the complete project process trail. In software development, if you failed to track the full progress of the project then your project, in the end, will be useless.
Detailed documentation.
The software process model provides the complete documentation of the project from start to end. In software development, documentation is a very important phase in which we write software documents like SRS document Design Document in later stages of development we use reverse engineering techniques then we use these documents for the updating the software product.
Track requirements
In every software project model Software requirement engineering is the very important phase of the software development process or simply Software development life cycle (SDLC). This phase is used to translate the unclear and incomplete idea of the customer into complete precise and formal specification this document is very must important and act as a bridge between the Customer, User, and Developers. Therefore, the importance of software requirement engineering is very much important for the development of effective and efficient software products.
Selection of the right technology.
The software process model at the start of the project guides us that which technology is best for our project. In software development, if you failed in the selection of technology which technology is best for the development of the project then it may also lead to the project being unsuccessful.
Accurate measurement of time and budget.
The software project model provides the exact time frame and information about finance required for the development.
If the time exceeds the completion of the project, then your project and development process leads to an unsuccessful project.
If the budget exceeds the completion of the project, then your project and development process leads to an unsuccessful project.
