                                    Elements of a DoD Strategy for
                                        Software Engineering
               • Support Acquisition Success
                          – Ensure effective and efficient software solutions across the
                            acquisition spectrum of systems, SoS and capability portfolios
               • Improve the State-of-the-Practice of Software
                 Engineering
                          – Advocate and lead software initiatives to improve the state-of-the-
                            practices through transition of tools, techniques, etc.
               • Leadership, Outreach and Advocacy
                          – Implement at Department and National levels, a strategic plan for
                            meeting Defense software requirements
               • Foster Software Resources to meet DoD needs
                          – Enable the US and global capability to meet Department software
                            needs, in an assured and responsive manner

        Promote World-Class Leadership for Defense Software Engineering

               1. The impact of requirements upon software is not consistently quantified
                  and managed in development or sustainment. “SW Requirements”
               2. Fundamental system engineering decisions are made without full
                  participation of software engineering. “SE/SW Integration”
               3. Software life-cycle planning and management by acquirers and
                  suppliers is ineffective. “SW Sustainment”
               4. The quantity and quality of software engineering expertise is
                  insufficient to meet the demands of government and defense industry.
                  “Human Capital”
               5. Traditional software verification techniques are costly and ineffective
                  for dealing with the scale and complexity of modern systems.
                  “SW Testing”
               6. There is a failure to assure correct, predictable, safe, secure execution
                  of complex software in distributed environments. “SW Assurance”
               7. Inadequate attention is given to total lifecycle issues for COTS/NDI
                  impacts on lifecycle cost and risk. “SW COTS / NDI / Reuse”

                   Software Industrial Base Study – July 2007
              There is a choke-point in availability of top-tier software
                      managers, architects, and domain experts.
      Supply of sufficiently trained SW developers is inadequate near-term.
       • Software Acquisition Training and Education (SATEWG)
                    – Chartered February 2008 by USD(AT&L) to add software competencies to

                    – Recent accomplishments:
                       − Developed software competency framework,
                       − Established SPRDE software competencies
                       − Gap analysis of SATEWG competency framework and DAU’s
                         Software Acquisition Management courses
                       − Current focus is on PM, Contracting and Test career fields

                           Software Sustainment Challenges

               • Software intensive systems encourage*:
                          – Build-a-little, test-a-little, field-a-little risk reduction
                          – Incremental and spiral development efforts
                          – Concurrent planning, development and sustainment activities
               • No longer a natural ‘break point’ where software
                 development can be transitioned to a
                 sustainment organization
                          – Technical capability of Government sustainment organizations
                            reduced due to acquisition reform
               • Planning for software sustainment now a lost art
                          – Acquisition programs no longer produce MIL-HDBK-347 Computer
                            Resource Life Cycle Management Plans

                              Better planning needed to partition software work
                             among multiple developers and increase competition

                           Summit/Workshop – Sep 2009
               • Purpose: “Recommend policy and guidance
                 changes to emphasize robust software T&E
                 approaches in Defense acquisition.”
               • Speakers from Government, Industry and
                 Academia
               • Conducted workshops on:
                          – How much software T&E is enough
                          – Software T&E involvement across the lifecycle
                          – Emerging paradigms: SOA, SoS, Security
               • Workshops specifically addressed:
                          – Policy & guidance, Human capital, RFP language,
                            SW T&E tools
               • NDIA Software Experts and DT&E sub-committee
