Fact findind technique
Fact Finding Technique(FFT):
There are mainly four fact should be collected:
- Data: The raw material used to create useful info.
- Process:The activity that carry out the mission.
- Interfaces:How the system interacts with people.
- Geography:Where data is stored, processes and inteface happen.
There are 7-fact finding techniques by which we collect fact for our projects:
- Studying & Sampling of existing documentation forms and files:
- organisational chart,History of projects suggestions note, customer comlaint
- companies mission,objective &strategic plan
- Policies,previous system studies &designs
- Manual&computerized databases
2. Research &site visits:
- Read computer journals,Rference books
- Internet
- Case-studies
3. Observation of the work environment:
- A technique where the system analyst either participates or watches a person perform activities to learn about the system.
4. Questionaries:
- Collect information and opinions.
- what benefits do you think the system might bring?? rating??ranking???
5. Interviews:
- Collect information from individuals face to face
- find facts,verify facts,classify facts
- Identity requirements
6. Joint Application Development(JAD):
- Group meetings that get the the end users,managers &analysts together.
7. Rapid Application Development(RAD):
This technique allows analysts to quikly create mock forms and tables to simulate the
implemented system and users suggests the changes to the prototype.
Siginificance of FFT:
Tools,such as data and process model documents facts and conclusions are drawn from facts. if facts are not collected tools can't be used effectively and efficiently.
