DOT NET Interview Questions - DotNetSpider

software development model you will follow. Definitely depending on client and project
scenarios it’s the project manager’s responsibility to choose a development cycle.
SDLC (System Development Life Cycle) is overall process of developing information
systems through multistep process systems from investigation of initial requirements
through analysis, design, implementation and maintenance. The days are gone when one
COBOL programmer used to analyze, test and implement software systems. Systems
have become complex, huge team members are involved, architects, analyst, programmers,
testers, users etc. To manage this number of SDLC models have been created.
Following are popular models which are listed:-

Waterfall Model.
Spiral Model.
Build and Fix model.
Rapid prototyping Model.
Incremental Model.
This section we will go in to fair depth of different SDLC models.
Water Fall Model
This is the oldest model. It has sequence of stages; output of one stage becomes input of
other.
Following are stages in Waterfall model:-
√

√
System Requirement: - This is initial stage of the project where end user
requirements are gathered and documented.
System Design: - In this stage detail requirements, screen layout, business
rules, process diagram, pseudo code and other documentations are prepared.
This is first step in technical phase.
Implementation: - Depending on the design document actual code is written
here.
Integration and Testing: - All pieces are brought together and tested. Bugs are
removed in this phase.
