2、e Description of Driving Event: The geography of KSC facilities does not lend itself to ease of team unity. The launch control center control rooms, from which systems engineers conduct tests, are a considerable distance from the OPF where technicians perform work on the vehicle. The remoteness of t

3、he two facilities impedes communications between engineers and technicians. As the program plans new control rooms and equipment, these new rooms could be located in the OPF between the two bays. Having the engineers in close proximity to technicians and the vehicle would improve the overall efficie

4、ncy of orbiter processing.Lesson(s) Learned: 1. Remote location of control rooms creates a natural barrier to communications and observation of work.2. Inconsistent or misleading use of nomenclature that does not conform to the OMI may cause confusion for technicians as they perform OMI procedures.3

5、. Technicians are so well versed in “good shop practice“ that inadvertent capping has occurred to purge and vent ports.4. Unfinished PRs that require disconnecting wires to other systems create operations constraints which may be transparent to systems engineers.Recommendation(s): Provided by IHSNot

Locate new control rooms within the facilities they service, centralizing the test team in one location for optimum performance.2. Review and correct orbiter and GSE displayed nomenclature to maintain consistency with

7、 OMIs.3. Educate all employees on the importance of communicating all problems and unusual occurrences during tailgate meetings or with a shop-wide awareness.4. Establish a procedure to notify system engineers that removal of electrical grounds will be a constraint to testing and system operations.E
