2、nt: Portable Computer System (PCS) Software is Not Developed Concurrently With Primary International Space Station (ISS) Flight Software Leading to Inadequate Multiple Element Integrated Testing (MEIT)Lesson(s) Learned: Due to the rapid pace of ISS assembly launches and the many and varied resulting
3、 configurations, Multi-Element Integration Testing (MEIT) with operational loads of Portable Computer System (PCS) software is limited and, in some cases, may only be accomplished in the brief time allocated for regression testing.Recommendation(s): Strive to accelerate scheduled releases for PCS so

Be prepared to delay schedules, if necessary, to assure that MEIT testing and astronaut training with the flight loads of PCS software are thorough and complete.Evidence of Recurrence Control Effectiveness: Code M - Concur: Every attempt is made to accelerate software releases where it can b

Schedules will be delayed where necessary to ensure that all necessary testing and training is conducted prior to launch.Provided by IHSNot for Re
