How to select the Software Model for the Software project?
Every Software model provides the software development cycle that helps us to efficient and effective development. By using the Software development process model, we can get the requirements to form the customer very effectively. The software process model provides an effective way of requirement management. The software Process model defines the product business modeling. It provides the testing environment throughout the development cycle. It provides the complete details of the project by documenting all the processes during development. Selecting the software product is a challenging task in the software development process. Select the process model according to the nature of the software product given below. We will discuss how we can select the right software process model in the right way.
But the question is when to use the software process model. The answer to this question is given below.
Step 1. Learn about SDLC Models
The software development life cycle is the process followed within a Software Organization. It is the detailed process that describes how to develop, maintain and replace the software product. Before Using the SDLC Process, you should have a clear understanding of the SDLC Model and experience in how to use the SDLC Modes in software development.
Step 2. Assess the needs of Stakeholders.
Defining requirements is the most important part of the software development life cycle. The process to gather the software requirement from customers and then analyzing those requirements and documenting them is called requirement engineering or requirement elicitation. If the feasibility report is positive from all aspects, then we start the requirement elicitation process. In this process, we start requirement engineering. We use different techniques to get requirements about the project. We discuss the feature and functionalities of the system and identifies the user and stakeholders. We must study the business domain, stakeholders' concerns and requirements, business priorities, our technical capability and ability, and technology constraints to be able to choose the right SDLC against their selection criteria.
Step 3. Define the criteria
Some of the selection criteria or arguments that you may use to select an SDLC.
- Is the SDLC suitable for the size of our team and their skills?
- Is the SDLC suitable for the selected technology we are using and implementing a solution?
- Is the SDLC suitable for clients' and stakeholders' concerns and priorities?
- Is the SDLC suitable for the geographical situation (Distributed Team)?
- Is the SDLC suitable for the size and complexity of our software?
- Is the SDLC suitable for the type of projects we do?
- Is the SDLC suitable for software engineering capability?
- Is the SDLC suitable for project risk and quality insurance?
Step 4. Decide
When you define the criteria and the arguments you need to discuss with the team, you will need to have a decision matrix and give each criterion a defined weight and score to each option. After analyzing the results, you should document this decision in the project artifacts and be aware of it with related stakeholders.
Step 5. Optimize
You can always optimize the SDLC during the project execution. You may notice upcoming changes do not fit with the selected SDLC. It is okay to align and cope with the changes. You can even make your own SDLC Models, which are optimum for your organization to the type of project you are involved in.
