Development Goals in Evoking a Core SETD Methodology

Form a library of Core SETD Methodologies• On demand availability

– Prescribes the development effort □ Identifies development commonalities □ Identifies development nuances/issues

• Enhances/streamlines development• Minimizes impacts to library owner

– Engineering organization□ Reuse processes when possible

– Engineering culture – Time, effort and cost

22

Step 1• Establish a classification of Systems

Step 2• Define a methodology in effective System Development

– Specific instances of system development types Step 3

• Create a SE development methodology for each specific instance based on priori knowledge

Step 4• Continually, improve the SE development methodology with posteriori

knowledge
