requirement analysis is a key constituent of the development cycles,
emphasis here is laid on visualizing the user needs vis-à-vis
technical requirements to be able to offer best possible solution and
also provide for traceability of the requirement changes during the
course of project execution. The primary motive here is to elaborate
on cascading effects of functional changes over the other development
phases like design and testing. This stage also involves exhaustive
study of the client processes, bottlenecks and intended objectives and
suitably documenting the same. The deliverables for this stage are a
Functional Requirements Specification document (FRS) and a System Requirements
Specification document (SRS). The above mentioned documents act as a
benchmark for the project objectives for the client as they map needs
into functional/ system / design aspects providing for a comprehensive
cross - reference. The logical conclusion of this stage is a pre-cursor
to actual software development phase.
stage involves identifying the architectural requirements of the project.
This is achieved in three stages firstly by identifying the components
of the proposed system, secondly the necessary interface requirements,
thirdly the necessary techniques/ algorithms/procedures that need to
be deployed for each of the components. The first> deliverable of this
stage is a Software Design document (SDD) consisting of architectural
diagrams, data models, interface descriptions, algorithms etc. The other
artifact of this stage would be a Hardware Design Document (HDD) consisting
of block diagrams, schematics, bill-of-materials etc as the case may
be. This phase may have as an option development of a prototype demonstrating
the functional capabilities of the proposed design.
stage involves identifying the priorities and implementation sequence
for each of the components of the proposed system. The criteria employed
here are necessarily to optimize on the time requirements and better
project management. This phase also brings out the latent associations
of various components and leverages on the experience of similar development
cycles undertaken in the past. The version control and configuration
management mechanisms are applied at this stage. The deliverables here
are a user manual and technical reference manual as decided by the nature
of system being developed.
phase contains test case design, test execution and results capture.
There are five different kinds of tests typically deployed Unit tests,
integration tests, validation test, system test and performance testing.
Artifacts are two documents Engineering Test Plan (ETP), test results
document as the case may be.
