Program Plan Intro
Systems development life cycle (SDLC):
- The seven phases in SDLC includes:
- Planning phase
- The planning phase includes creating a goal statement for project.
- It defines a high level plan for intended project.
- It sets the scope of project.
- The project plan denotes a formal, approved document that would manage and control entire project.
- A project manager creates a project plan and ensures that project finishes within given deadline and budget.
- Analysis Phase
- In analysis phase the firm would analyze business requirements.
- It refines goals of project into defined operations and functions of intended systems.
- The business requirements denote specific business requests made by system so as to successfully complete project.
- The requirements management denotes process of managing changes to requirements in business.
- A requirements definition document would prioritize all business requirements based on importance order.
- Design phase
- The design phase creates description for system features and operations.
- It includes following items:
- Screen layout
- Business rules
- Process diagrams
- Pseudo code
- The graphical user interface (GUI) denotes an
information system interface.
- Development phase
- The development phase transforms detailed design documents into actual system.
- During this phase, the team defines
programming language for development. - A scripting language may provide interactive modules to website.
- Object oriented languages may group data into objects.
- Testing phase
- The testing phase keeps all project modules under testing environment for elimination of bugs and errors.
- It verifies that system meets all requirements mentioned in analysis phase.
- Bugs denote defects in information system code.
- The test conditions denote steps that must be performed and expected result for each step.
- Implementation phase
- The system is placed into production, detailed documentation is performed.
- The users begin actual operations in business within system.
- Maintenance phase
- The organization performs corrections, changes and up gradations to ensure that system meets requirements.
- Corrective maintenance would make system changes to flaws in design, errors in coding or issues in implementation.
- Preventive maintenance would make system changes to reduce chances for system failure in future.
- Planning phase
