NDIA SE Architecture Committee 25 June 2012 Agenda: General Info – Nothing new Task # 4 Status (S. Dam) Task # 8 Status (R. Carson)
2
Task # 4: Is the use of authoritative DoDAF-like architectures critical for a successful systems integration effort? (Navy). Reusable architectures/environments, system hierarchies. (AF) SED: define “architecture” context and task plan. Establish architecture committee.
3
Situation –Industry and others observation is that use of DoDAF is 1.Often disjointed from program technical work and/or performed in duplication with a programs’ other systems engineering efforts, which can result in limited utility of the DoDAF data and artifacts; 2.Appropriate application of DoDAF in conjunction with bigger picture SE efforts is often misunderstood; and 3.Lack of documented, measurable benefits of a unified architecture framework standard and it’s applicability to future DoD program and mission success. –Increased industry and DoD awareness and understanding of how architecture is an integral part of the systems engineering process to enable model based design, and a defined path forward to address current DoDAF limitations Proposal –Identify recommendations for: Should the DoDAF be mandatory? Where should the DoDAF be used? Where should it not be used? Adjustments needed to current DoDAF path including topics of standards, tools, etc How DoDAF should be integrated into larger SE efforts, including what DoD guidance is needed in this area Suggested alternatives to DoDAF Areas for future continued investigation 3

Presentation Title: Use of DoDAF for Systems Integration: An NDIA SE Division Architecture Subcommittee Update (Submitted Ref. #14830) Abstract: In April 2012 NDIA SE Division formed a committee to address the question: “Is the use of authoritative DoDAF-like architectures critical for a successful systems integration effort?” A number of issues related to DoDAF were discussed, including: 1) industry and others observation is that use of DoDAF is often disjointed from program technical work and/or performed in duplication with a programs’ other systems engineering efforts, which can result in limited utility of the DoDAF data and artifacts; 2) appropriate application of DoDAF in conjunction with bigger picture SE efforts is often misunderstood; and 3) lack of documented, measurable benefits of a unified architecture framework standard and its applicability to future DoD program and mission success. To address this question, it was determined that we need to increase industry and DoD awareness and understanding of how architecture is an integral part of the systems engineering process to enable model based design, and define a path forward to address possible current DoDAF limitations. A proposal was developed to: a) identify recommendations for adjustments needed to current DoDAF path including topics of standards, languages, tools, etc.; b) describe how DoDAF should be integrated into larger SE efforts, including what DoD guidance is needed in this area; and c) recommend priorities for ongoing architecture framework standards (e.g., IDEAS Group, OMG UPDM) and innovations (e.g., Ontology working groups, INCOSE MBSE activities). This presentation will present preliminary results of this investigation. 7

Submitted Abstract New Opportunities for System Architecture Measurement The United States Government Accountability Office, the United States Department of Defense ((Carter, 2010) and (Thompson 2010)), and industry (NDIA 2010) have all made the case for better measurement in support of program success. Last year’s NDIA System Development Performance Measurement working group report (NDIA 2011) attempted to define a broad set of leading indicators building on the Practical Software Measurement (PSM) and INCOSE System Engineering Leading Indicators (SELI) Guide (INCOSE 2010). The workshop conducted as part of the NDIA study identified System Architecture as a high priority area for a leading indicator but was unable to identify suitable candidates. Objectives for architecture measurement were described as “Evaluates the architecture from the perspectives of quality, flexibility, and robustness, stability, [and] adequacy of design rules.” The report chartered further activity as a need ”to identify a consistent, common measure of architecture quality in the current community of practice to include as a consensus recommendation.” To address this residual need, an architecture measurement working group has been formed with participation from companies representing INCOSE, NDIA, and PSM. The introduction of architecture modeling tools and their evolution has created opportunities for defining meaningful measures. This paper reviews previous measurement literature and process standards to identify measurement concepts applicable to “architecture”. The process activities and outputs of the System Architecture processes defined in ISO 15288 and the INCOSE Handbook were reviewed and along with the measurement concepts defined in Carson (2011) and Olson (2008). Classes of measurement include quality and completeness of architecture, and work progress measures vs. planned work. The emphasis is on identifying measures that can serve as leading indicators and predictors of program impacts. Measures derived from Rechtin and Maier (1997) heuristics are also examined in this context. Measures related to US Department of Defense Architecture Framework (DoDAF) viewpoints are also examined. The results were compiled and a set of potential measures defined. The measures are documented using the PSM methodology. General techniques are proposed that take advantage of the opportunities afforded by the current architecture modeling environment to provide a basic measurement plan for architecture including leveraging existing measurement concepts found within the SELI. The result is a comprehensive tailorable suite of measures that can provide decision-making data to program managers and program leaders.
