Following the anomaly that occurred during the December Boeing Starliner Orbital Fight Test (OFT), NASA and Boeing formed a joint investigation team tasked with examining the primary issues, which occurred during that test. Those issues included three specific concerns revealed during flight:
An error with the Mission Elapsed Timer (MET), which incorrectly polled time from the Atlas V booster nearly 11 hours prior to launch.
A software issue within the Service Module (SM) Disposal Sequence, which incorrectly translated the SM disposal sequence into the SM Integrated Propulsion Controller (IPC).
An Intermittent Space-to-Ground (S/G) forward link issue, which impeded the Flight Control team’s ability to command and control the vehicle.
Som så många har misstänkt så har Boeing problem med att skriva mjukvara

There was no simple cause of the two software defects making it into flight. Software defects, particularly in complex spacecraft code, are not unexpected. However, there were numerous instances where the Boeing software quality processes either should have or could have uncovered the defects. Due to these breakdowns found in design, code and test of the software, they will require systemic corrective actions. The team has already identified a robust set of 11 top-priority corrective actions. More will be identified after the team completes its additional work.

In addition to these reviews, NASA is planning to perform an Organizational Safety Assessment of Boeing’s work related to the Commercial Crew Program. The comprehensive safety review will include individual employee interviews with a sampling from a cross section of personnel, including senior managers, mid-level management and supervision, and engineers and technicians at multiple sites.
SpaceX har redan gått igenom ovanstående genomgång. Tanken var att Boeing skulle få samma behandling redan då men av olika skäl tyckte dom det var för dyrt att lägga fem miljoner dollar på den genomgången.
