  22. 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

  23. 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
