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
Implementation for
Evoking a Core SETD Methodology
 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

 Development roadmap readily in
place and available
 SETD not reinvented each time
• Tailoring whim
– Experience based
– Knowledge based
 Each improvement updated in
library
 Establishes SE Industry credentials
•
•
