During this phase, the system is designed to satisfy the functional requirements identified in the previous phase. Since problems in the design phase could be very expensive to solve in the later stage of the software development, a variety of elements are considered in the design to mitigate risk. These include: Identifying potential and defining mitigating design features. Performing a security risk assessment. Developing a conversion plan to migrate current data to the new system. Determining the operating environment. Defining major subsystems and their inputs and outputs. Allocating processes to resources. Preparing detailed logic specifications for each software module. 9.2.4 Development Effective completion of the previous stages is a key factor in the success of the Development phase. The Development phase consists of: Translating the detailed requirements and design into system components. Testing individual elements (units) for usability. Preparing for integration and testing of the IT system. 9.2.5 Integration and Test Phase Subsystem integration, system, security, and user acceptance testing is conducted during the integration and test phase. The user, with those responsible for quality assurance, validates that the functional requirements, as defined in the functional requirements document, are satisfied by the developed or modified system. OIT Security staff assesses the system security and issue a security certification and accreditation prior to installation/implementation. Multiple levels of testing are performed, including: Testing at the development facility by the contractor and possibly supported by end users
