If you are a pioneer in the development of software then it is important that you learn the Requirement Management Cycle before beginning of development. This will give you an idea of ways to increase your success rate, since there are only 16 percent chances of software success without the requirement management. The life cycle of software performs certain procedural steps which help to achieve the software development goals. Understanding the life cycle of software is significant, so that we can understand where the requirement management fits.
It is imperative to follow the steps involved in the life cycle of software development as these steps are designed to ensure the successful development of software or any application or a product or may be a device. Complete life cycle is combination of different phases which form different life cycle models. In this article we’ll explain the stages of software life cycle.
- Requirement Gathering
In any form of software development the first step is gathering requirements. Let’s say you need to build a business application. Now you have the requirements distributed into different forms but they aren’t written properly. It means that you have to review every process and every detail of your business for the requirement inventory creation. Once the inventory of requirement is generated in the form of papers this means that we got something. The first step is essentially to gather requirements as many as possible, without the analysis. Gathering of the specifications will give us an abstract outline of the basic project proposal. This procedure is called as zero stage. It leads to cultivate different stages over it. The resultant of stage zero will form the base for the project’s scope and vision.
Requirement analysis plays a key role in the development of successful product. The cause for two in every three failures of any software is the flaw in the analysis process. You have gathered a lot of requirements and now all the requirements need to be screened. You’ll dig deep to filter out the real requirements in analysis phase. Each specification from the inventory will be evaluated one by one and will be classified as being either declined or picked. The classification process will be based on certain predefined roles which will standardize the requirements. You will get every rule correlated with the area, and the rules can be controlled by validations, logical laws, or an internal mechanism caused by choosing something. You have received filtered requirements after the analysis process has been completed. The analysis process defines the project foundation and 37 per cent raise the success rate.
Analysis phase will remove the unrealistic goals that will be difficult to process and will refine the procedure for defining sharp and achievable goals. This process is related to the people who provide the requirements and is the second most important step even before considering any software development.
We have, until this point, obtained all the specifications related to the development of particular software. Analysis phase contributes to the design phase and the technical individual steps into practice here. The technical person will generate design based on the requirement gathered during the process of analysis. Following the requirements outlined in the analysis process, designer will be able to complete the design step by step. The analysis phase refers to the design phase as a road-map and any mistake in the analysis phase can also cause problems here.
When the design is finished then the project is handed over to the developer and he codes to make the design work. He develops various algorithms depending on the problems needed to handle. He develops the operational schema for the entire application and if this is incorrect then it is due to the inaccuracy of analysis phase. So it is clear that the streamlined requirement analysis can lead to a product that is perfect by increasing project success ration both on budget and on time.
After the development system is complete, and therefore it needs to be tested so that we can verify that the requirements have been met as per the analysis phase. Software testing is the application assessment toward user-gathered requirements and system specifications. The documentation or requirement specification produced in the analysis phase plays a benchmark for the verification of developed model via testing.
Throughout all these software development life cycle stages requirement analysis phase is playing a key role. This reflects a light on the importance of the software requirement specifications in the software development and if the requirements are not met then software failure occurs. That’s why it’s so important and the first two phases of SDLC are associated with 37 per cent of software failures.
Thus our product has reached to its last destination after successfully passing through all the steps and that is deployment. In the life cycle of software development this step is linked to the distribution of finished product to the user who requested it to be developed. In case it is consumer software then this stage is referred to the rolling completed software out to consumers. Now the consumer can build user manuals for the delivered software which will explain how to use it and then implement a solution.
For you to understand that this is the procedure that ReqStudio handles, this all discussion has been introduced. The tool is designed to gather all the requirements and then perform analysis. After the analysis it will help to evaluate the estimated cost and time for the product. This is a very simple and effective execution procedure which makes the requirements tangible, understandable and achievable. The main objective of this is to derive refined requirements through it.
So when you use our tool, you’ll find out that all the above steps will be done via ReqStuido.
