Software Development

   
     
  Software Development is a process to understand the need of customer and develop a software that fulfill all requirements as well as it should be user friendly so that all new user take interest to use the new software.

ANALYSIS:-
During this phase, analyst produces technical documentation containing business requirements and their technical solutions. During this phase, application architecture is also designed while considering the functional and non-functional requirements. This phase may include studying existing system and identifying GAP analysis. This GAP analysis will identify the key areas which require improvements. In such cases analysis requires more time.

DESIGN:-
The Conceptual Design stage is where an identified need is examined, requirements for potential solutions are defined, potential solutions are evaluated and a System Specification is developed. The System Specification represents the 'technical requirements' that will provide overall guidance for system design. Because this document governs all future development, the stage cannot be completed until a Conceptual Design Review has determined that the System Specification properly addresses the motivating need.
Key steps within the Conceptual Design stage include:

  • Need Identification
  • Feasibility Analysis
  • System Requirements Analysis
  • System Specification
  • Conceptual Design Review

IMPLEMENTATION:
Reducing a design to code may be the most obvious part of the software engineering job, but it is not necessarily the largest portion. An important (and often overlooked) task is documenting the internal design of software for the purpose of future maintenance and enhancement. Documentation is most important for external interfaces.

TESTING:
The various components of the system are integrated and systematically tested. The user tests the system to ensure that the functional requirements, as defined in the functional requirements document, are satisfied by the developed or modified system. Prior to installing and operating the system in a production environment, the system must undergo certification and accreditation activities.

MAINTENANCE:
The system operation is ongoing. The system is monitored for continued performance in accordance with user requirements, and needed system modifications are incorporated. The operational system is periodically assessed through In-Process Reviews to determine how the system can be made more efficient and effective. Operations continue as long as the system can be effectively adapted to respond to an organization’s needs. When modifications or changes are identified as necessary, the system may reenter the planning phase.
