System Analysis & Design, Phase IV SDLC 4
Objective of Phase IV: The System Development Process
Phase IV of the SDLC is the
The implementation phase is the
development of all parts of the system, including software, documentation, and the new
operating procedures, that were designed in the design phase.
To be successful in the
implementation phase we will manage the programming, assign the tasks based on the
experience of the staff, and coordinate these activities according to the schedule.
We will use
test planning, which determine different methods of testing based on what part of the system we
need to evaluate.
These methods are unit testing, integration tests, systems tests, and acceptance
It is very important to fix any bugs in the system prior to utilization; the cost of trying to
fix errors after the fact is much greater.
The documentation needed consists of both system
documentation, and user documentation.
Three types of user documentation are needed.
Reference documents, are used to perform a specific task and are usually in the form of online
Procedure manuals are used to perform business tasks, and tutorials on how to use the
Finally, we will documentation navigation controls.
These are indexes, links to other
pages, table of contents, and other intelligent agents to help users to perform functions,
commands, and explain terms used in the new system.
The implementation phase is the transition to the new system.
We will develop a migration
plan, which tells us specifically what activities are performed and by whom.
strategy will be selected describing what parts of the system will be switched over, when its to
take place, and how much of the system to convert at a time.
We will focus on training the
individuals to use the system, and set up a system support to help people use the system.
