2、 management and modeling tool was the primary investigation management tool for the Columbia accident investigation; however, acceptance of the tool was not consistent across investigative groups because some investigators considered it a developmental tool rather than an operational tool.Descriptio
3、n of Driving Event: Investigation Organizer (IO) - is a Web-based pre-decisional collaborative information management and modeling tool designed to support mishap investigation teams. IO provides a centralized information repository that can be used by a distributed team of investigators to store di
4、gital products relevant to an ongoing mishap investigation. It was used by the Columbia Accident Investigation Board (CAIB) to connect data from various sources to the storyboard that the Board used to guide its investigation. IO was developed, maintained and hosted at NASA Ames Research Center (ARC
5、). IO maintainers, Ames Research Center civil servants and contractors, pull required data electronically from the NASA-provided Process Based Mission Assurance (PBMA) database to populate the IO fault tree. IO representatives were placed within each investigation group of the CAIB. Documents, digit
6、al photographs/video, links were uploaded to the IO database to support the engineering/management investigation logic tree. The logistics “footprint” of IO-trained personnel was extensive.Lesson(s) Learned: Although Investigation Organizer was the primary investigation management tool for the Colum
7、bia accident investigation, it was not initially utilized across all investigative groups within the CAIB. It had been previously used on only one other investigation, the loss of the CONTOUR spacecraft. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-
8、Acceptance of the tool was not consistent across groups. Some investigators complained that the Board was being forced to use a developmental tool in an operational environment.Recommendation(s): a71 Move the IO tool from a development environment to an operational environment to gain acceptance a

The ARC IO personnel should expect to support logistics/training during investigations unless the tool can be made easier to use.a71 Codify IO use in t
