2、 and use of multiple systems cause additional delay and tax the IT support staff.Description of Driving Event: Columbia accident investigation personnel were required to learn database tools with which they were unfamiliar, adding inefficiencies in Board and Task Force startup time.Lesson(s) Learned
3、: Database tools that most people are unfamiliar with will cause delays in initiating investigation. Multiple systems, implemented to satisfy specific needs, cause additional startup delay and tax the time of IT support staff.Recommendation(s): a71 Develop an appendix/annex to the Contingency Action
4、 Plan (CAP) and annually update the definition of critical tool requirements based on established selection criteria. A criteria-based tool selection process was not used resulting in a tool being procured whose capabilities were not fully understood by the primary Board and TF users.a71 Avoid real
5、time, verbal, or informal tool requirements as they will be treated by the developers as requirements that they can freely interpret and make judgments on without consultation with users, ultimately resulting in product deliveries that do not meet expectations.Provided by IHSNot for ResaleNo reprodu

7、ata from the investigation will be archived.a71 Do not permit contractors to define and manage the Board and Task Forces IT requirements. This becomes a financial driver for them.a71 Separate database administrator function and general task force IT support (SRs, user configuration set-up, etc.).a71
8、 Identify a candidate database and data management tools that could be implemented quickly. The data management tool and approach should meet the anticipated availability, security, firewalls, capacity, and on-site/off-site access requirements for supporting a major mishap investigation without sign
9、ificant modification or development.a71 Make a data management tool/approach a part of the NASA CAP, and review annually at a minimum.a71 Avoid having the same information in too many places, as data will diverge.a71 Brief the Board Chairman and Board members upon arrival regarding their electronic
10、tools and advise them not to bring in new systems to be force-fit with systems initially laid in by NASA IT administrator.
