Which quality approaches, methods and tools would you propose to mitigate each of the following factors ?

1. Errors in ground-based computer simulations of how modest spacecraft thruster firings were projected and subsequently carried out aboard the spacecraft throughout its interplanetary route to Mars remained unreported.

2. In comparison to the earlier Mars Global Surveyor mission, the operational navigation crew was not fully briefed about the intricacies of the way the Mars Climate Orbiter was aimed in orbit.

3. A last, optional engine firing to boost the spacecraft's course relative to Mars before arrival was proposed but not carried out for a variety of interrelated reasons.
4. The project's systems engineering function, which is responsible for tracking and double-checking all interconnected aspects of the mission, was insufficiently robust, which was exacerbated by the first-time handover of a Mars-bound spacecraft from a group that built and launched it to a new, multi-mission operations team.
5. Some project engineering groups' communication channels were unprofessional.
6. The small mission navigation team was oversubscribed, and its work was not peer reviewed by independent experts.
7. Personnel were not sufficiently trained in areas such as the relationship between the mission's operation and its detailed navigational characteristics, or the process of filing formal anomaly reports.
8. The methodology for verifying and validating certain engineering requirements and technological interfaces between specific project groups and the project's primary mission contractor was insufficient.
