Explain the V-Model?

Answer Posted / arulselvi.a

Development starts with information gathering. After the
requirements gathering BRS/CRS/URS will be prepared. This
is done by the Business Analyst.

During the requirements analysis all the requirements are
analyzed. at the end of this phase S/wRS is prepared. It
consists of the functional (customer requirements) + System
Requirements (h/w + S/w) requirements. It is prepared by the
system analyst.

During the design phase two types of designs are done. HLDD
and LLDD. Tech Leads will be involved.

During the coding phase programs are developed by programmers.

During unit testing, they conduct program level testing with
the help of WBT techniques.

During the Integration Testing, the testers and programmers
or test programmers integrating the modules to test with
respect to HLDD.

During the system and functional testing the actual testers
are involved and conducts tests based on S/wRS.

During the UAT customer site people are also involved, and
they perform tests based on the BRS.

From the above model the small scale and medium scale
organizations are also conducts life cycle testing. But they
maintain separate team for functional and system testing.
