Systems Development Tools and Techniques
Prototyping
A systems analyst can describe and simplify and information system by using a set of business,data,object, and process models.
Computer-Aided Systems Engineering (CASE) Tools
-Early working version of an information system.
-Speeds up the development process significantly .
-Can be an extremely valuable tool.
Modeling
-A systems analyst can describe and simplify an information system by using a set of business,data,object and process models.
Systems Development Methods
Structured Analysis
-traditional systems development technique
-Uses the systems development life cycle to plan, analyze , design, implement and support an information system.
Objected-oriented (o-o) analysis
-combines data and the processes that act on the data into things called objects.
-Systems analysts use O-O to model real-world business processes and operations.
Joint Application Development and Rapid Application Development
-JAD -Team based fact finding.
-RAD -compressed version of the entire process.
Other development methodologies
-In addition to structured analysis and O-O methodologies, you might encounter other systems development techniques.
-Microsoft Solutions Framework (MSF) documents the experience of its own IT teams.
