This document discusses Joint Application Development (JAD), Joint Requirement Planning (JRP), and Computer-Aided System Engineering (CASE) tools. It describes the typical participants in a JAD session and JRP meeting. It also outlines the advantages and disadvantages of using JRP to develop requirements for complex systems. Finally, it provides an overview of CASE tools, including examples of types of tools, how they support the development process, and their potential advantages and disadvantages.

2. JOINT APPLICATION DEVELOPMENT(JAD)

3. JAD PARTICIPANT
 The typical participant of JAD session are;
1. Leader
2. Manager
3. User
4. Sponsor
5. System Analyst
6. Scribe
7. IS staff

5. JOINT REQUIREMENT PLANNING(JRP)
 JRP is a process whereby highly structured group meetings
are conducted for the purpose of analyzing problems and
defining requirements.
 JRP is a subset of a more comprehensive joint application
development or JAD technique that encompasses the entire
systems development process.

6. JRP PARTICIPANT
 JRP participants are similar to that of JAD.
1. Manager
2. User
3. facilator
4. Sponsor
5. System Analyst
6. Scribe
7. IS staff

8. ADVANTAGE OF JRP
 Easy to find the requirement of complex system.
 More focus on requirement to develop best system or
complete system for an organization.

9. DISADVANTAGE OF JRP
 Extensive training is required for JRP as it is a group form

10. COMPUTER-AIDED SYSTEM ENGINEERING(CASE) TOOL
 Case Tool are the software programs that helps the
development team to do their jobs more efficiently and more
effectively.
 These tools support the drawing and analysis of system
models.
 Some case tools also provide prototyping and code
generation capabilities.
 Examples : Oracle's designer 2000, Rational's Rose,
Platinum's Erwin, etc.

11. TYPES OF CASE TOOL
 There are various types of case tools used for various
purposes.They are;
1. Diagramming tools
2. Computer display and report generator
3. Analysis tools
4. A control respiratory
5. Documentation generator
6. Code generator

12. ENVIRONMENT HAVING CASE

13. TYPES OF CASE TOOLS
 Sometimes CASE tools are classified in to following
categories due to their activities:
1. UPPER CASE Tools
2. LOWER CASE Tools
3. INTEGRATED CASE Tools

14. UPPER CASE TOOLS
 They support the analysis and the design phase. They include
tools for analysis modeling, reports and forms generation.

15. LOWER CASE TOOLS
 They support the coding phase, configuration management,
etc.

16. INTEGRATED CASE TOOLS
 It is known as I-CASE and also supports analysis, design and
coding phases
