Q
DEFINITION OF PROBLEM
A
- Feasibility is considered
- initial look at existing system to find improvements
- stage begins with initial brief investigation by systems analyst
- benefits and limitations of current
3
Q
INVESTIGATION AND ANALYSIS
A
- Input= feasibility report
- Methods for investigation: questionnaires, interview, meeting, document analysis, observations.
- stage results in user requirements
4
Q
DESIGN
A
- Follows requirements specification
- methods of data capture designed including length, type & val
- prep, input & storage considered
- prototype created so end users comments can be gathered
5
Q
IMPLEMENTATION
A
- uses design spec, and puts it into place
- when coding is created for inputs, processes and output
- creates working software that can be tested
6
Q
TESTING
A
- testing for bugs or errors in the code
- testing to see if the system meets all of the user requirements
7
Q
INSTALLATION
A
- placing finished product into use via a strategy: parallel, phased, pilot, direct
- staff training can be done using the tested and completed software
- data transferred into new system
8
Q
DOCUMENTATION
A
- Given to end user do be referred to when needed
- Includes: detailed program spec, recovery procedures, user manual, operating procedures
- program spec for maintenance
- security details for rights to software
- can provide reference material for training
