TESTING CPF MAINTENANCE CONTRACT STATED: “TESTING SHALL BE AT THE SAME LEVEL AS THE CPF PRIME CONTRACT”
NAVY VERSION 1. 0 PROBLEMS • REQUIREMENTS • WORK SPLIT BETWEEN SITES • POOR PLANNING • FACILITY SCHEDULING • VERSION RELEASE DOCUMENT
NAVY VERSION 1. 0 PROBLEMS (CONT) • • • RELEASING AUTHORITY CONTRACTOR TESTING AT SEA TESTING NUMEROUS DEFECTS STAFFING/EXPERIENCE LEVELS NO MEANINGFUL METRICS COLLECTED
SUCCESS OR FAILURE? • POLITICALLY FACILITY WAS JUDGED TO BE A SUCCESS • STANDING UP THE FACILITY – SUCCESS • PRODUCING THE FIRST IN-SERVICE BUILD – FAILURE
CHANGES TO FACILITY • REQUIREMENTS GROUP STOOD-UP • CONTINUOUS IMPROVEMENT GROUP ESTABLISH • INDEPENDENT TESTING GROUP ESTABLISHED • INCREASED STAFFING FOR SMa. RT
CHANGES TO FALICITY (CONTINUED) • MINI-SYSTEM INSTALLED • AUTOMATED CONFIGURATION MANAGEMENT • CLOSER TIES TO REQUIREMENTS GROUP DEVELOPED • TRANSITION OF SOFTWARE TO INSERVICE AUTHORITY • FACILITY REORGANIZED

SOFTWARE SYSTEMS ENGINEER RESPONSIBILITIES • ASSESS IMPACT OF SOFTWARE AND SYSTEM CHANGES • COORDINATE SYSTEM STUDIES AND INVESTIGATIONS • REVIEW TEST PLANS AND TEST PROCEDURES • OBSERVE ALL FORMAL TESTS
QUALITY ASSURANCE • QUALITY MANAGEMENT – DOCUMENT, V & V SOFTWARE PROCESS – INCREASE PROCESS CAPABILITY AND MATURITY – RAISE QUALITY AWARENESS AND PROVIDE TRAINING – CONTINUOUS IMPROVEMENT
QUALITY ASSURANCE (CONTINUED) • QUALITY CONTROL – VERIFY ALL DEFECTS AND ENHANCEMENTS ARE DOCUMENTED AND TRACKED – WITNESS SPR CLOSURES, DELTA, AND SYSTEM TESTS – MONITOR SOFTWARE BUILDS AND DELIVERY PREPARATION
CONTINUOUS IMPROVEMENT HIGHLIGHTS • REQUIREMENTS REVIEW • PEER REVIEWS • TRAINING – 247 HOURS PROGRAMMERS – 173 HOURS TESTERS • NEW VERSION RELEASE PROCESS • INCREMENTAL BUILDS • NEW TESTING PROCESS
SOFTWARE TEST PROCESS Development Testing Program Debug SPR Closure Beta Site Testing Version Testing Operational Evaluation Survivability Test Beta Site Testing Delta Test Shipboard Alongside Testing System Test Shipboard At Sea Testing
BETA TESTING • OCCURS ON A CONTINUOUS BASIS • CFNOS AND CFNES INVOLVED • DEFECTS ARE DOCUMENTED – ATTEMPT TO REPRODUCE ON PREVIOUS VERSION • FREE PLAY
VERSION TESTING • VERSION SURVIVABILITY TEST – COMPARES SYSTEM PERFORMANCE WITH PREVIOUS VERSION PERFORMANCE – FULLY AUTOMATED – FOCUSES ON MISSILE THREAT PROFILES, TEWA PROCESSING – REPORT PRODUCED AND REVIEWED
DELTA TEST • INTEGRATION TESTING • WHITE BOX FOCUS • DEMONSTRATES ALL CHANGES FUNCTION CORRECTLY IN THE SAME BUILD • TEST REPORT PRODUCED/REVIEWED
SYSTEM TEST • NORMALLY STATIC • FOUR PHASES – EW/ASW – AWW/RADAR – FULL LOAD TRACKING – OVERALL (8 HRS) (2 HRS) (6 HRS) • REPORT PRODUCED/REVIEWED
TESTING IMPROVEMENT S • TEST CELL ENHANCEMENT STUDY – FULLY DOCUMENT PROCESS • • • DEVELOMENT AND USE OF METRICS FORMALIZATION OF PEER REVIEWS AUTOMATED TESTING DEFECT REPORTING DEFECT DATA COLLECTING TESTING/PROGRAMMING TOOLS
CONCLUSION • • • INITIAL TESTING POOR TRYING TO DO TOO MUCH AT ONCE TESTING PROCESS NOW IN PLACE OBTAINING REPEATABLE RESULTS FINE TUNING PROCESS STAGE
