Software Development Life Cycle

For Application Software development a methodology is using. Which is called systems development life cycle (SDLC), also referred to as the application development life-cycle. There are step by step process to development the project effectively. This process is using for all type of development Software Development, Web development, Mobile App development and others application software development. Please find the step wise process.

1. Project Planning, Preliminary analysis

The purpose of phase 1 is to conduct a preliminary analysis of software requirement Like propose alternative solutions for more effective solution of the Requirement, It also help to reduce the cost of product, describe costs and benefits of application and submit a preliminary plan with recommendations.

2. Systems Analysis, Requirements Definition

In this phase we defined the project goal, functioning of Application. It is the process of identifying the all facts and requirements for development, identifying problems and recommending improvements to the system. Analyzes end-user requirements, needs and also removes any inconsistencies and incompleteness in these requirements.

3. Systems Design

In this phase we create the blue prints of the application and describes required features, functioning and operations in detail, Creating screen layouts, business rules, process diagrams, data digram, pseudo code and other documentation.

4. Development

This is the real coding phase. In this phase we divide the application in module and develop the application.

5. Integration and Testing

In this phase we integrate all module bind together into a special testing environment, then checks for errors, bugs and interoperability and all testing methodology.

6. Acceptance, Installation, Deployment

This is a final stage of application development. In this stage the application is put for production and runs for actual requirement.

7. Maintenance, Evaluation, Disposal

This is the Evolution and Maintenance phase of application. Changes, Addition of functionality and updating in application occurs in this phase, If some requirement occurs for moving the hardware and software or making the transition to a new system. The purpose is discard or destroy information, hardware and software that is being replaced.
