The implementation phase
Is the process of defining how the inforrmation system should be built
Ensuring that the information system is operational
Used that information system meets quality standard
The major steps
involved in this phase are
Implementation
conversion
Acquizition of hardware, software and services
End user Training
System documentation
Steps
System
The cost
The hardware and software
Required for running the system must be made fully operational before implementation.
Is built and tested to ensure that it performs as designed
Fixing bugs can be immense, testing is one of the most critical steps in implementation
Conversion
Is also one of the most critical and expensive activities in the system development life cycle
User training
Main topics of such type of training are
System documentation
How to process the data
How to take out the reports
How to enter the data
The new system may get installed but without proper training of users, it may not be of good use
How to execute the package
Program is planned and the required training given to users.
Helps users to appreciate the new features of the new system and helps build trust and appreciation for the new system.
Needs assessment is done to understand the training needs of the users.
Provide all documentation necessary to effectively operate and maintai the system
Evaluates the effectiveness of the system
Includes all technical documentation delivered during the project.
Types of implementation
Phased
Parallei
Direct cut over
Pilot
Involves the previous system to
be eliminated.
The old system is no longer available.
functional and operational.
Involves both systems together over a
period of time
Helps to test the new system without
losing data
Allows users to familiarize themselves
Old system remains as a backup
Gradual introduction of the new
system
The previous system is
progressively discarded
Conversion is easier for the user
The new system is installed for a small number of users
Helps ensure the functionality of the new system
Programmer and customer can evaluate the system
