  1. GCSS-J Best Agile Practices

  2. GCSS-J Program Overview Joint Logistics Environment: Visibility of logistic processes, resources, and requirements • Where is it? • How will it get here? • When will it get here? • Web-based system (NIPR / SIPR) managed by DISA • Retrieves authoritative data on facilities, units, ships, aircraft, etc. • Provides decision support tools to analyze, manipulate and display the data • Users collaborate to integrate combat support data • Users represent Maintenance, Supply & Services, Health Service & Support, Movement Services, Civil Military Engineering & Personnel Mngmt • Began as Rapid Improvement Team (RIT) -Dec 2001 • Working Release 7 - “agile” for approx 2 yrs LTG Gainey, JS/J4 Ops Sponsor: “I want capability delivered in dog-years!” 2

  3. SPRINT SPRINT GCSS-J Scrum The Sprint Cycle Initial Planning DiscoveryPlanning Sprint Planning Sprint Review Daily Scrum Release Planning Product Backlog Sprint Backlog Production Ready Feature • Currently supporting 2 releases per year (goal is 4) • Multiple (3-5) Sprints per release • Development Sprints are one month in duration • Sprints are NOT fielded but available for users on the First Look Site Scrum is an agile software development framework 3

  5. Evaluation Structure Critical Operational Issues Mission Based: Traced to Joint Capability Areas (JCAs), levels 1-3 COI 1 . . . Measures of Effectiveness / Measures of Suitability Mission Based: JCAs Level 4-7, or OV-5 system’s activity model MOE 1.1 MOE 1.1 . . . Measures of Performance Task Based: Traced to Universal Joint Task List (UJTLs), or User input – tasks they perform MOP 1.1.2 MOP 1.1.3 MOP 1.1.1 . . . Measures of System Attributes Technical Measures: • Key Performance Parameters (KPPs) • Critical Technical Parameters (CTPs) • Key System Attributes (KSAs) MOSA 1.1.2.a MOSA 1.1.a Majority of Evaluation Structure can be “Solution Agnostic”

  6. Evaluation Structure (cont.) Joint Capability Areas (JCAs)/Universal Joint Task List (UJTL) MOE = Measure of Effectiveness

  7. Interoperability Integrated within Evaluation Structure Task MOPs Mapped to External Interfaces • Each Interface is mapped to the mission tasks (MOPs) that require effective end-to-end data exchange to be successful • If a data exchange is NOT • Timely • Accurate • Complete • Useable • Effective in determining which of the interfaces are truly ‘critical’ for mission accomplishment Task MOPs = Mission Tasks may FAIL during testing or post-fielding So if GDSS doesn’t meet Interoperability criteria, then four mission tasks (MOPs) could be affected - Information exchanges are correlated to the tasks they support. - A single interface may provide different information exchanges for different tasks. - Some tasks are mission critical, some are not (determined by users).

  8. Assessing Risk to Determine Level of Test 0 0 2 Minor Change / Fix Minor Change / Fix 2 • Functional Reqmts (FR) developed for each User Story • FR’s associated with Functional Areas, and categorized • Low risk items for use-case testing (users not needed) • High risk items for Op Mission Thread testing (users needed) • Design of Experiments (DOE) employed to determine key factors and effects of varied environmental conditions Example: Maintenance and Supply Services FR 125 FR 127 FR 126 Maintenance 1 No change from last release: no testing required New Capability Enhancement Risk: Moderate Requires OMT testing Supply/Services 0 0 New Capability Enhancement Impact on Mission Likelihood of Failure Query Tool Joint Decision Support Tools Functional Area Display/Map Collaborate Predict Moderate 1. Maintenance 1 Minor 2. Supply/Services No Change Risk: Minor Use-case test only New Enhanced Minor OMT Tests Focused on Higher Risk Areas 8

  9. Best Practices • Early Involvement • Users and Testers • Collaborate on issues, metrics, data elements, conditions • Develop mission-based evaluation structure • Readily accommodates emerging user stories and functional reqmts • Risk-based • Level of Test determined by risk associated with how s/w change impacts the affected tasks/activities • “Right sizes” test scope = less burden on operational user test • Mission-focused • Founded in Joint doctrine (JCAs, JPs, UJTLs) • Links information exchanges to tasks/missions • Answer the “so what” to decision makers

  10. Best Practices • Continuous Monitoring • Continuous data collection on operational system • Reliability , Availability, Maintainability • Information Assurance • Integrated team (DIA & JITC) scans continuously throughout development • Annual assessment of hosting facility • Remote Data Collection • Use of Defense Connect Online to observe and record user actions

  11. Lessons Learned • Requirements & the JCIDS Process • requirements evolve based on warfighter needs • agility to modify the evaluation plan (COI, MOE/S, MOP) for every GCSS-J increment/release • TES / TEMP • Not a good fit for Agile programs • cannot write detailed descriptions of test events, objectives, scope, as we currently do • shift emphasis to test plan (release) or test cases (sprint) • Does not include key stakeholders endorsements (JS/J6 and DAA) • Embedded Instrumentation • automation essential to Agile methods • requires built-in instrumentation to support lifecycle testing • Test Integration at Sprint Level • all test disciplines (dt, ot, iop, sec) • Test windows too small for a statistically relevant RAM evaluation • Information Assurance (IA) evaluations in hosting facilities
