Description of Driving Event:
Consistent User Involvement in Software Development Process
Lesson(s) Learned:
Several software developments are on the critical path for launch and operation of the ISS. While some software elements have had the early involvement of a multi-disciplinary team that includes users and operators, many have not. The lack of user involvement results in increased schedule and safety risk to the program.
Recommendation(s):
The ISS program should follow a concurrent engineering approach to building software that involves users and other key discipline specialists early in the software development process to provide a full range of perspectives and improve the understanding of requirements before code is developed.
Evidence of Recurrence Control Effectiveness:
NASA concurs with the recommendation. The US portion of the ISS is structured around an Integrated Product Team approach. This approach did, and does, include specialists from users and operators during all phases of development. The international partner's development is followed closely by subsystem and operations working groups to enhance system understanding and involvement by system experts, crew, and operations personnel.
