CURRENT POSITION • DCS Process Improvement Lead at AWL PRESENTATION OUTLINE • • • • • • Fundamental Overview of A Process NAVAIR BPI Study 1998/1999 F/A-18 AWL Overview Overview of CMMi Overview of Airspeed Conclusion WHAT IS A PROCESS? PROCESS n., a logical organization of people, procedures, and technology into work activities designed to transform information, materials, and energy into a specified result. A high level view of how work is accomplished. Information, Materials, energy Specified Result 90 80 70 60 East West North 50 40 30 20 10 0 1st Qtr 2nd Qtr 3rd Qtr 4th Qtr WBS 1.

[i.e., Product or process or policy, etc.] PROJECT LEVERAGE AREAS There are three major determinants which affect the success or failure of a program. These are Product cost, schedule and Quality. The leverage areas are depicted in the triad. While each area is important, process is the unifying factor in the three. PEOPLE PROCESS TECHNOLOGY WHY IS A PROCESS IMPORTANT? • Process provides a methodology for intelligently and efficiently integrating people, tools, procedures and technology • People usually are only as capable as they are trained to be so • Working harder and longer hours are not the solution • But working smarter and more efficiently using processes is the Solution • Technology applied without a supporting infrastructure is disaster. It could bring the expected benefits if the people are trained and if a process is applied judiciously. PROCESS MANAGEMENT ASSUMPTIONS • The ultimate assumption verified by the military and commercial sectors is that the QUALITY of a system is highly influenced by the QUALITY of the process used to Design, Development and Maintain the system. • The cost, performance and delivery of systems will all be improved when processes are defined and used consistently across the project. NAVAIR BPI STUDY 1998 • Study initiated to improve our business practices under the leadership of NAVAIR head, Admiral Lockhard. • Darrell Maxwell and Carl Hall co-chairs on Best Practices Initiative (BPI) Software Development Strategy Core Processes Team CP5-1 with Admiral J. Dyer manager. • One year to visit commercial and military sectors and determine a solution to improve our SSA business practices. Briefing given to NAVAIR in Feb. 1999. • I will present a portion of our committee’s research and findings today. Site Visit Best Practices Utilize the Software Engineering Institute Capability Maturity Model (SEI- CMM). Process improvements defined by the SEI-CMM Levels (1 through 5) results in 30% productivity increase for each level improvement. Test costs shift from 50% of the total costs to 30% by improving from a Level 3 to a Level 5 organization. 30% reduction in defects for each Level improvement. People are motivated to improve by Senior Management commitment and vision. An initial investment and reinvestment up to 5% of the S/W product cost in process improvement initiatives. Improve by using corporate leadership teams (SEPG’s, PAT’s, and SEC’s) to motivate and encourage the development of processes and procedures. Integrate Systems and Software Engineering processes together. Organizations with similar maturity levels work better together. System Strategies for Tomorrow’s Success Process Focus TEAM will reduce the cost of software development and maintenance through the use of disciplined processes that are defined and implemented by both TEAM and contractor organizations. Organization/Capabilities Focus TEAM will optimize and maintain the best skills mix within government and industry, develop and maintain the core system software expertise within TEAM, and eliminate redundancies among the various system software entities. The system software organization will be flexible and responsive to the fluctuating marketplace. Workforce Focus TEAM will develop a corporate culture characterized by excellent communications, knowledgeable leadership, and commitment to employee professional and personal growth. Empowered employees use policy, documented guidance, and defined TEAM processes supported by training, in the fulfillment of their job responsibilities. Our TEAM places value on, and works to maintain, work force continuity in core capabilities. Guiding Principles • Committee used 4 principles: 1) Organized abandonment of: Products, Services, Processes, Markets, & distribution channels 2) Organize for systematic, continuing improvement 3) Organize a systematic and continuous exploitation, especially of its successes, the organization has to build a different tomorrow on a proven day 4) Organize a systematic innovation, that is, to create the different tomorrow that makes obsolete and, to a large extent replaces even the most successful products of today • These Disciplines are not just desirable, they are conditions for survival Probability of Success 120% Product Success 100% 80% 60% SEI 1 & 2 Success 40% SEI 3,4, & 5 Success 20% 0% 0 1 10 100 1000 10000 SW Size (Function Points) (1) Capers Jones, Becoming Best In Class, Software Productivity Research, 1995 briefing (2) 1 Function Point = 50 SLOC ADA, 40 SLOC C++, 320 SLOC Assembly 100000 STRATEGIC GOALS • • • • • • • • Goal 1.1 – Implement the SEI CMM across all team software organizations Goal 1.2 – Utilize Software Suppliers that are evaluated at Software CMM Level 3 or higher Goal 2.1 – Establish Team Software Development Center of Excellence.

In turn, employees accept responsibility to play an active role in their growth. Goal 3.2 – Improve Workforce Continuity in Software Expertise F/A-18 AWL OVERVIEW 75% of Naval Aviation 90% of Naval Aviation Now 2006 F/A-18s will be flying well into the second quarter of the 21st Century Over 1300 aircraft, and still in production F/A-18 IPT MISSION • • • • MISSION “…To improve the warfighting capability of U.S. Navy, U.S. Marine Corps and Foreign Military Sales F/A-18 & EA-18Gs.” CHARTER Transform an operational need into a description of system performance parameters Develop a system configuration through the use of an iterative process of definition, synthesis, analysis, design, test, and evaluation Integrate technical parameters and ensure compatibility of all physical, functional, and program interfaces in a manner that optimizes the total system definition and design Integrate reliability, maintainability, safety, survivability, and human engineering, into a total engineering effort to meet cost, schedule, and performance objectives SCS LIFE CYCLE PHASES AWL PRODUCTS • System Configuration Sets • Additions to, and modifications of, over 10 million lines of software code • Acquisition Products - stand alone RDT&E projects • • • • • New technology radars Improved infrared sensor for air-to-air and air-to-ground combat Reconnaissance system Improve existing radars for air-to-air and air-to-ground combat Plus additional, similar projects • Weapon Integrations • • • • • JDAM - All weather, GPS guided, precision bomb JSOW - Glider with bomblets Sidewinder (all-aspect, infrared guided, air-to-air missile) Stand-Off Land Attack Missile Enhanced Response (cruise missile) And many more • Fleet Response • System problems and new, unpredicted threats • 7 Foreign Military Sales customer requirements THE AWL IN DETAIL The Advanced Weapons Lab, China Lake -- where Sensor / Smart Plane / Smart Bomb combinations are developed, and wired together to test their real-world, realtime performance - including full-scale, in-lab mock-ups prior to flying. Now, let’s unpack that statement… Full-scale – because it takes a nanosecond (.000000001) for an electron to travel along 1 foot of computer cable. And, in digital warfare, nanosecond precision is essential. So, you must test with full-scale distances between sensors, plane, and bombs. In-Lab Mock-ups – because in-flight testing costs more than 25 times as expensive as in-lab, mock-up tests. Sensors – because these “eyes and ears” are our current technological edge. Smart Planes – because air power is the US’s preferred tool for power projection. Smart Bombs – because they’re more precise and limit collateral damage. Combinations – because there are nine sensors, seven airframes, and many kinds of weapons available to accomplish various missions. Wired together – because it takes integrated software to make the sensors, plane, and bombs talk to each other. Test real-world, real-time performance – because it’s all just theory until this happens, and it only happens at China Lake. WIRED TOGETHER i.e., an example of Weapons and Systems Integration Every eyeball , lightening bolt , and brain , represents a piece of software code written and tested in fullscale, in-lab mock-ups at China Lake.
