The activities of this phase translate the system design produced in the Design Phase into a working information system capable of addressing the information system requirements. The development phase contains activities for requirements analysis, design, coding, integration, testing, and installation and acceptance related to software products. At the end of this phase, the system will be ready for the activities of the Integration and Test Phase.
These activities consist of several tasks that are the responsibility of the developer. The developer shall place the outputs under the Configuration Management Process and perform change control in accordance with it. The developer shall also document and resolve problems and non conformance found in the software products and tasks.
The developer shall select, tailor, and use those standards, methods, tools, and computer programming languages that are documented, appropriate, and established by the organization for performing the activities of the Development Process.
Plans for conducting the activities of the development phase should be developed, documented and executed. The plans should include specific standards, methods, tools, actions, and responsibility associated with the development and qualification of all requirements including safety and security. Separate plans may be developed. The detailed project Work Breakdown Structure (WBS) developed during the Planning Phase should be expanded to incorporate the WBS structure into each module or software configuration item to be developed.
human-factors engineering (ergonomics), interface, operations, and maintenance requirements; the design constraints and qualification requirements. The system requirements specification shall be documented.
architecture shall identify items of hardware, software, and manual -operations. All the system requirements should be allocated among the hardware configuration items, software configuration items, and manual operations.
requirements
Establish and document software requirements, including the quality characteristics specifications described below.
This process may be employed by any two parties, where one party (reviewing party) reviews another party (reviewed party).
CONCLUSION
The systems development phase is made of up a series of stages. These must be accomplished sequentially, if a successful development of an information system is to be conducted for any organization.y
