2.4.2 NASA Systems Engineering Capability Pre‐Assessment Plan

Abstract

Over the past several years, several events [Ref 1] have led NASA to re-examine how it engineers systems. As a result, NASA initiated a Systems Engineering Excellence Initiative in 2001, and established a Systems Engineering Working Group (SEWG) to form and implement a common framework for engineering systems within NASA 1 .The common framework is based on the development and sustainment of a state-of-the-art level of competence in systems engineering, measurable in three specific areas; Concepts and Processes; Knowledge and Skill of Workforce; and Tools and Methodologies. The framework must also include a method of providing continuous assessment and improvement.Cursory review led a SEWG sub-group (The Assessment Subgroup) to conclude that utilization of a recognized maturity model, such as the Software Engineering Institute's (SEI) Capability Maturity Model Integrated (CMMI ® ), would provide the means for ensuring continuous assessment and improvement of the framework.Prior to launching a CMMI ® assessment of systems engineering at all ten NASA Centers (estimated to cost in excess of $500,000), the Assessment Subgroup proposed to conduct a pre-CMMI ® assessment (hereafter referred to as a pre-assessment) to evaluate the current level of competence of systems engineering throughout the Agency, and determine whether or not CMMI ® should be implemented.1 This effort is sponsored by NASA's Office of the Chief Engineer.

7.2.2 Learning from Lessons Observed–Mitigating Resistance to SE Process Change

“…There were many models from which to choose. (Sheard 1997a(Sheard , 1997b (Sheard 2001a) As confirmed by (Andary 2004), capability maturity models (CMM) 7 and business process models need to be carefully evaluated with a pre-defined objective criterion aligned to the goals of the change activity. The process model evaluation criteria were from those who used process models and expert-consultants.…”
