Structured planning functional decomposition diagrams

Structured Planning: Functional Decomposition Diagrams

Process Modeling:

DFDs

Data Modeling: ERDs

Structured Design: Structure Charts

Logic Specification:

Decision rules within DFD processes

Code Generation:

A Central Repository


Structured planning functional decomposition diagrams

  • What you want in a Case Tool

  • Good Diagramming Tools

  • Consistency Checking Across Levels (i.e.within DFDs)

  • Consistency Checking Across Tools (i. e. DFDs to ERDs)

  • Automatic Generation of Diagrams (i.e. get ERD skeleton from DFD or vice versa)

  • Code Generation

  • Why Organizations Adopt Case:

  • Provide new systems with shorter development time.

  • Improve productivity of the SDLC process

  • Improve the quality of the SDLC process

  • Improve worker skills

  • Improve portability of systems

  • Improve management of SDLC

  • Why Organizations Reject Case:

  • High cost of purchasing CASE

  • High cost of training personnel

  • Low organizational confidence in the IS department

  • Lack of standard methods in the organization

  • Viewing CASE as a threat to job security

  • Lack of confidence in usefulness of CASE products
