Macro System Paradigms - Developer

l In house development

  • Company knowledge, workflow, processes, cases
  • Motivation, Acceptance

l External development

  • Expertise, efficiency for documentation,

implementation and validation

  • Less user-friendly, enhancement barriers

Macro System Paradigms - Models

l Design Models

l Waterfall Model

(Requirements, Design, Implementation, Verification, Maintenance)

l V Model

(Concept, Architecture, Detailed Design, Test & Verifications)

l Rapid Prototyping l Agile Programming

e.g. Extreme Programming (XP)

(Frequent Loops)

Rollout – Motivation of Users

  • User-friendly
  • Support, training, documentation, intuitive parameters
  • From-Ourselves-For-Ourselves
  • Implementation / Specification
  • Embedding in enhancement cycle
  • Change request lists (easy to address)
  • Confidence into the system
  • No black box
  • “Fun” part
  • Management support
  • Enable / force learning time
