Analyses and life tests are not budgeted and planned for.
Life testing is not integrated with other developmental test activities nor completed before design release.
Realistic life test environments are not developed based on actual operational mission profile environments.
Failure data from life tests is not analyzed in sufficient depth to determine root causes.
Accelerated testing techniques are not well understood and proven.
Procedures are not in place to feed back results of life test efforts to the design program.
