The Seven Phases Of SDLC

The planning phase involves aspects of project and product management. This may include:
- Resource allocation (both human and materials)
- Capacity planning
- Project scheduling
- Cost estimation
- Provisioning
The outputs of the planning phase include: project plans, schedules, cost estimations, and procurement requirements. Ideally, Project Managers and Development staff collaborate with Operations and Security teams to ensure all perspectives are represented.
The needs and expectations of stakeholders are identified, and the software requirements are defined.
This may include:
- Identifying the needs and expectations of stakeholders
- Defining software requirements
- Creating user stories, use cases, or requirements documentation
- Conducting user research and user testing
Creating a detailed design of the software, including the architecture, user interface, and technical specification.
This may include:
- Creating a detailed design of the software, including the architecture, user interface, and technical specifications
- Identifying and addressing any potential design challenges
- Creating wireframes, mockups, or prototypes
Where the actual Software is built and coded.
This may include:
- Writing code and building the software according to the design
- Integrating any necessary third-party libraries or frameworks
- Conducting unit testing
The Software is tested to ensure it meets the requirements and is fit for its intended purpose.
This may include:
- Testing the software to ensure it meets the requirements and is fit for its intended purpose
- Conducting functional testing, performance testing, and user acceptance testing
- Identifying and addressing any bugs or errors
The Software is deployed to the end- users and made available for use.
This may include:
- Installing the software on the intended systems or platforms
- Configuring the software for the target environment
- Training users and providing documentation
Ongoing support, updates, and enhancements to the software, as well as troubleshooting and problem-solving as needed. The product will be retired when it’s end of life is reached
This may include:
- Ongoing support and troubleshooting for the software
- Making updates and enhancements to the software as needed
- Planning for the end-of-life of the product and retirement plan.
