Introduction
In this blog, we will discuss the prerequisites in software requirement engineering. In software development, the most important thing is an idea and after that, we do requirement elicitation for that idea and then we define pre- and post-requirement for that software idea. In requirement elicitation, the most important thing is quality requirements because these requirements help us in the software construction process and make the project successful. The worst thing in the software development process is to revise development projects two to three times. Before beginning any project, we must be sure about prerequisites, and after checking that all the permits have been obtained and make sure that all the requirements are obtained then move to the next step of the software development life cycle (SDLC). The term Measure Twice and cut once is very important in software development because Measures all the prerequisites first and then starts the development process.
Importance of Prerequisites
In Software development, the prerequisites are very important because if any organization or individual programmer wants to develop a high-quality software product, they must ensure prerequisites and high-quality practice. Such practice emphasizes the beginning of the project.
- If you emphasize these practices at the end of the project, then you emphasize system testing where many people think and ensure quality assurance.
- If you emphasize these practices in the middle of the project, then you emphasize construction practices where the development team starts designing and developing the project.
- If you emphasize these practices at the start of the project, then you need a proper plan for the development process and need high-quality requirements for high-quality products.
Determine the system you are working On.
In Software development, the prerequisites are very important because if any organization or individual programmer wants to develop a high-quality software product, they must ensure prerequisites and high-quality practice. Such practice emphasizes the beginning of the project. Before the start of development determines the project, you are working on what is the nature of the project like life-critical information critical. Determine the time frame and budget for that project. Before beginning any project, we must be sure about prerequisites, and after checking that all the permits have been obtained and make sure that all the requirements are obtained then move to the next step of the software development life cycle (SDLC).
Cause of Incomplete Planning.
- A big project requires more efficient planning for making the project successful likewise a small project also requires 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 revision is the worst part of development.
- Incomplete Requirements may lead a project to be Unsuccessful.
- Before beginning any project, we must be sure about prerequisites and after checking that all the permits have been obtained and make sure that all the requirements are obtained then move to the next step of the software development life cycle (SDLC) if you forget something in the first stage of software development then your project may lead to an unsuccessful project.
Problem Definition Prerequisites
In Software Development the prerequisites are very much important for long-term projects as well as short-term projects. But before the start of any project identify the problem that may cause the project to lead to the failed software product. Example:
- Incomplete Planning? Poorly define the project scope
- Ineffective leadership? Fail to identify the assumptions
- Fail to track the progress. ? Lack of detailed documentation.
- Fail to track requirements
- Fail in the selection of the right technology.
- Inaccurate measurement of time and budget.
- Cultural terms in global terms.
- Lack of datil in project planning.
Requirement Engineering Prerequisites
Complete Planning
A big project requires more efficient planning for making the project successful likewise a small project also requires 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 revision this is the worst part of development.
Efficiently define the project scope
In the Requirement Engineering process of defining the project, the scope is very much important because if you define the scope of the project as poorly or incomplete scope your project leads to unsuccessful
Effective leadership
In software development the if project leader is ineffective and poorly manages the project improperly defines the iteration of completion of a 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
Track the progress.
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.
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 updating the software product.
Full track requirements
Software requirement engineering is a 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
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
- 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.
Detailed project planning.
- A big project requires more efficient planning for making the project successful likewise a small project also requires 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 revision this is the worst part of development.
- Incomplete Requirements may lead a project to be Unsuccessful.
- Before the beginning of any project, we must be sure about prerequisites and after checking that all the permits have been obtained and make sure that all the requirements are obtained then move to the next step of the software development life cycle (SDLC) if you forget something in the first stage of software development then your project may lead to an unsuccessful project
Amount of time you spend on Requirement Engineering
In Software Development the prerequisites are very much important for long-term projects as well as short-term projects. But before the start of any project determine the amount of time you spend on the requirement engineering process as well because software development time and budget are very important for the completion of a successful project.
- 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.
- If you emphasize these practices at the end of the project, then you emphasize system testing where many people think and ensure quality assurance.
- If you emphasize these practices in the middle of the project, then you emphasize construction practices where the development team starts designing and developing the project.
- If you emphasize these practices at the start of the project, then you need a proper plan for the development process and need high-quality requirements for a high-quality product
