7) Description of the final report - ANS-Test and Evaluation Master Plan (TEMP)
Evaluation using analytical models (CAD, CAE,CAM, CAS) -- In conceptual design phase -
ANS-Analytical Evaluation
ENGINEERING T&E
• Evaluation of engineering models, service test models, system components, breadboards,
mock-ups, and rapid prototypes
• Verify basic performance and physical design characteristics
• Design changes are still low cost
○ ECP - Engineering Change Proposal
• In Prelim Design and Destial Design & Development - ANS-Type 1 Testing
DEVELOPMENTAL T&E
• Evaluation of prototype and early production models
• Qualification of the system (temp cycling, chock and vibration testing i.e. "Shake and Bake")
• Qualification: the process of demonstrating whether or not a system (or component) is
capable of satisfying
• Ex. McKinney Climatic Laboratory (Eglin AFB, FL)
• In Detail Design & Development - ANS-Type 2 Testing
SYSTEM INTEGRATION & TEST
• Production models evaluated at designated test sites
• Testing of production representative items in an operationally representative environment
• First tests of the fully integrated system
• Objective -- verify the TPMs and customer needs are satisfied
During Production and/or Construction Phase - ANS-Type 3 Testing
OPERATIONAL T&E
, • Testing performed when system is in the operational utilization and support phase
• Objective -- assess and improve system in operational use (change maintenance policies,
support for modifications, study for repair rates, aircraft block upgrades etc.) - ANS-Type 4
Testing
Tests accomplished to verify individual system performance characteristics. - ANS-Performance
Tests
Temperature cycling, shock and vibration, humidity, wind, salt spray, dust and sand, fungus,
acoustic noise, pollution emission - ANS-Environmental qualification
Tests are conducted to determine material characteristics relative to stress, strain, fatigue,
bending, torsion - ANS-Structural tests
Tests are accomplished on one more system elements to determine MTBF, MTBM -
ANS-Reliability qualifiaction
Tests are conducted on one more system elements to assess the values for mean active
maintenance time - ANS-Maintainability demonstration
Tests are often accomplished to verify compatibility among the prime equipment, test and
support equipment, test and support equipment, and transportation and handling equipment -
ANS-Support equipment compatibility tests
Tests are often accomplished to verify the relationships between people and equipment, people
and software, the personnel quantities and kill levels required, and training needs -
ANS-Personnel test and evaluation
Verification of operational and maintenance procedures is often accomplished - ANS-Technical
data verification
Verification of operational and maintenance software is accomplished. This includes software
units (CSUs), computer software configuration items (CSCIs) - ANS-Software verification
varification of various elements of the proposed supply chain with the applicable elements of
system is accomplished. Packaging and handling methods, warehouse and storage methods, -
ANS-Supply chain element compatibility tests
identify as early as possible where incompatibility may exist and where additional design activity
may be required - ANS-Compatibility tests with other elements within the higher-level SOS
structure
The probability that a system or product will perform in a satisfactory manner for a given period
when used under specific operating conditions - ANS-RELIABILITY
