SAND 2007-6454C 14 Benefits Utilized Systems Engineering approach – used a process to develop a process –The more precision you have in a process, the better you can institutionalize the process effectively Functional architecture clarified the relationships between tasks and enabled good cohesion Understand the relationships of the inputs and outputs to the phase /gates –Create clarity in tasks and document deliverables (artifacts) needed at each phase –Prevent unnecessary, non-value added tasks –Clear understanding of roles and responsibilities Balanced the tasks (leveling) and assure they rollup to the right level Visual representation of the relationships between tasks and gate outputs in subsequent phases Established connectivity to artifacts and activities – making sure the behaviors are tied to the structure of the process Flow and intent of process is more explicit and understandable when represented graphically

SAND 2007-6454C 15 Conclusions / Next Steps Conclusions It is critical that you follow format and structure that will enable the model to be executable –Understanding the fundamental model structure was critical for complex process Assuring completeness was key in developing the next level of the model Understand the value of static versus dynamic model Next Steps Model is still being tested and will continue to build on the key artifacts and elements in other phases Pilot executable on specific elements of the process for upcoming development program
