Explain the software development life-cycle

Software development is the process of creating and maintaining the computer software. It is a set of instructions given to the computer for performing a specific task.

The life cycle of software is the procedure or process of developing software. This life cycle contains six steps.

These are the steps of the software development life cycle.

• Analysis and planning
• Requirements
• Designing
• Development
• Testing
• Releasing
• Maintaining

1. Analysis and planning

In the process of creating software, at this stage, the developer produces a list of required things. In this phase, the developers stayed connected with the stockholders and company owners and gather information about their requirements. The software makers target the products and then assess their functioning, financial source potential, cost production, and end-user requirements.

In this step, software developers decide what they can use! What they can avoid! They align the work list that what to do at the first step then on the second step then further.

When you are done with an analysis and planning then you can step into the next phase.

2. Requirements

The information gathered during the planning and analysis process must be effectively translated into requirements for the software development team during this section. A software requirement specification a use needs document, a requirement matrix document, and a few of the significant papers that are developed using this procedure.

A professional developer first makes a listing of any company owner’s requirements and local customers’ demands. They can not start work on the designing phase until they have the detail of all requirements of the clients.

3. Design

This is the phase of software design and appearance. This phase includes the design of the system, selection language, setting of templates, and providing a platform.

After ending the planning and analyzing needs now the time is to select the design for your software. Suggest to the software developer or designer what type of software appearance you are demanding.

The developer manages the interface, algorithms, and flow of data with the database design.

The interface of the user and the experience of the user these two applied in the designing stage. You can provide guidance face-to-face about your desired user interface and able to communicate in an effective manner. Software design also focuses on color patterns. You can design the structure as you need or desire. Adobe is the best tool for it.

The developer team is allowed to check the final appearance of the software and also give permission to make further adjustments without rewriting the whole code or program.

4. Development

It is the beginning of the project’s real development phase in this step the development team members break down software modules and translate the software demands into the product’s code. It is a time-consuming stage. So that the software developers are aware of your expectations and you can monitor your progress at this stage, it’s critical to have a clear timetable and set of milestones.

After ending the designing section the team of software development software goes through the development phase. It is the phase of production programming codes for systems programs. It is often called the sensitive stage of software development it can make your software the best and if went wrong disruption can take place as a result. This is the stage of turning the plans into actions.

5. Testing

Crucial for quality assurance. In this process, after developing the software the developers put the software into different tests. These tests are used to measure do the planning is executed in the correct way! Does software fulfill the requirements? Is the design right and attractive?? Also, check if any mistake happens in the developmental phase.

Basically in this section, the developer focuses on identifying the bugs and flaws if he found any issues then they fix them before sending them to marketplaces.

Sometimes these testing can take place in a virtual setting and sometime in automated or with robots. This testing includes performance testing, functional testing, security testing, unit testing, usability testing, and acceptance testing.

6. Releasing phase

After testing the whole software it is time for the software developers to release the software for local users and send it to the market. There should be a proper schedule made by the developers to release it. Schedule including date of releasing time of releasing and select the target audience. For example, if you are going to introduce some features target a few clients and if you are going to launch a brand of software target a worldwide audience.

7. Maintenance

It is the last step in the software life cycle. In this stage software development authorities always monitor the performance of launched software to find the errors and bugs. If the user is facing an issue it helps in reducing it. The software maintenance team always works for enhancing the performance of the software.? By introducing new features for the software these maintenance teams keep the software on track and free from bugs.

8. Software development lifecycle models

There are five models of the software development lifecycle.

1. Agile Model

Focus on identifying the software errors early but provide a solution when the user gives instructions.

2. Waterfall Model

It focuses on project management structure, but there is less flexibility for adjustment after a phase is over, it best works for small, clearly explain projects.

3.Iterative Model

This model can work with a small amount of resources required. Focus on enhancing the system version. Manage risks easily.

4. Spiral Model

Best for complex projects but can be expensive. It blends the iterative model’s repeated cycle with the waterfall model’s linear flow.

5. Big Bang Model

It is not good for big projects but can be effective for practicing projects, and for mini projects which only contain two to three developers.

Conclusion

In conclusion, the discussion was about the process planning, analysis of requirements, designing the software, implementation, software testing, releasing or deployment, and maintenance of software phases that make up the software development lifecycle. Software development models ais the model’s chain which helps in maintaining software from risks and works to achieve the software goals. For long-term success, it is a cyclical procedure that assures the development and advancement of high-quality software products while also accomplish customer demands.
