Understanding the Software Development Life Cycle — IT Certificate
• Feasibility study.
• At minimum, the outcomes of the systems concept development phase should include a
documented feasibility study and a cost-benefit analysis.
Planning
During the planning phase, a project management plan and other planning documents are
developed, including the basis for acquiring the resources needed to achieve a solution.
• Multiple tools are used with multiple interfaces.
• Separate tools are used for different types of changes.
• Tools are managed across diverse and/or multiple geographic locations.
Requirements Analysis
During the requirements analysis phase, user needs are analyzed and user requirements are
developed. A detailed functional requirements document is then created. Outcomes from this phase
include business and functional requirement documents.
Design
During the design phase, detailed requirements are transformed into a complete, detailed systems
design document. The focus of this document is on how to deliver the required functionality. The
outcome of this phase is a technical design document.
Development
During the development phase, a design is converted into a complete information system.
Development also includes:
• Acquiring and installing the system and its environment.
• Creating and testing databases.
• Preparing test case procedures.
• Preparing test files.
• Coding, compiling, and refining programs.
• Performing the test readiness review and the procurement activities.
Outcomes of this phase include:
• A developed system ready for testing.
• User test scripts and plans.
Integration and Testing
During the integration and testing phase, a demonstration to show that the developed system
conforms with requirements, as specified in the functional requirements document, must be
completed. Integration and testing are conducted by quality assurance staff and users, and test
analysis reports are produced.
