Stages of Software Development

The stages of software development models describe phases of the software cycle and the order in which those phases are executed. Each phase produces deliverables required by the next phase in the life cycle. Requirements are translated into design. Code is produced according to the design which is called the development phase. After coding and development, the testing verifies the deliverable of the implementation phase against requirements. The testing team follows the Software Testing Life Cycle (STLC).

There are six stages of software development they are as follows.

• Planning
• Analysis
• Design
• Development
• Testing
• Maintenance

Planning

It is the planning of the perfect plan, calculating the strengths and weaknesses of the project development of software is meaningless. planning kicks off a project flawlessly and affects its progress positively.

Analysis

This phase is the main focus of the project managers and stakeholders. Meetings with managers, stakeholders, and users are held in order to determine the requirements like; Who is going to use the system? How will they use the system? What data should be input into the system? What data should be output by the system? These are general questions that get answered during the requirements gathering phase.

Design

Once the analysis is complete, the step of designing takes over, which is basically building the architecture of the project. System Design helps in specifying hardware and system requirements and also helps in defining overall system architecture. The system design specifications serve as input for the next phase of the model.

Development

The actual task of developing the software starts here with data recording going on in the background. Once the software is developed, the stage of implementation comes in where the product goes through a pilot study to see if it’s functioning properly.

Testing 

The testing stage assess the software for errors and documents bugs is there is any. During this phase, all types of functional testing like unit testing, integration testing, system testing, acceptance testing are done as well as non-functional testing are also done.

Maintenance

Once the software passes through all the stages without any issues, it is to undergo a maintenance process where it will be maintained and upgraded from time to time to adapt to changes.
