3、ngle NASA system on February 1 that could meet the requirements set for the Columbia Accident Investigation Board (CAIB) and Columbia Task Force (CTF). The Process Based Mission Assurance - Enhanced Security (PBMA-ES) system, using a proven COTS “engine“ was rapidly deployed within a dedicated stand

The system provided immediate secure, web-based operability of key functionality to support a mobile, in-the-field, investigation activity including, action tracking, calendar, do
5、cument management, and database capabilities. Neither the CAIB, the CTF, nor the PBMA management team could reasonably anticipate or identify all of the requirements at the beginning of the investigation (both functional and interface) needed to support the investigation. The requirements “critical
6、needs“ continued to evolve from the initial request for “action tracking,” i.e., customization of JSC form 564, to web links, to full text search, to advanced library support capabilities. In addition, particularly early-on, there existed a continuous, often tension-filled negotiation process betwee
7、n the needs of the multi-headed customer(s) (CAIB) and the IT-security community. The absence of clear IT security policies exacerbated the requirements change process. Finally, the degree and complexity of library management requirements, as driven by Department of Justice (DOJ), did not emerge unt

9、licy disconnects, and ultimately frustrated customers who were looking for immediate implementation of their desired changes. Lesson(s) Learned: Real-time, crisis-mode systems engineering can never capture all potential future requirements. You do the best that you can and make the best decisions yo
10、u can with the information you have at the time. The overarching lesson learned is that NASA needs to have a web-based, Mishap Investigation Support System (MISS) in-place and operational, “locked and loaded“ on hot standby to support major mishaps. The system must fulfill the requirement set identi
11、fied in the next section. It is equally important to have a designated (hot standby) management team ready to support the myriad of operational requirements and customization needs that one can expect to emerge. In the final analysis, the experienced PBMA management team provided the necessary suppo
12、rt to implement the dynamically evolving CAIB requirements. Recommendation(s): Establish a NASA baseline information technology Mishap Investigation Requirements Set (MIRS) to include the following elements: a71 MISS Management Team: Experience dictates that a management team be available to quickly

14、al activitiesa72 Work group administrationa71 Financial/resource managementa71 Sustaining engineering and operationsa71 Collaborative Environment: Use a web-based, fully integrated, COTS knowledge management system application to provide immediate field support for the investigation team (i.e., memb
15、ers, contacts, calendars, task management, web-links, etc.). A COTS product will ensure best-available, market-driven capabilities are available to support mishap investigation Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-teams.a71 Independence/Po
16、rtability: Expect to confront the issue of accident board independence and ensure that the MISS is established as a stand-alone hardware/software infrastructure behind a NASA firewall but portable so that it can be easily moved to any NASA Center.a71 IT Security: A well-defined and documented NASA I
17、T security policy applicable to all systems is essential. Recommend baselining NASA system host-center firewalls, secure socket layer encryption, and a secure but usable single factor user-authentication policy. A generic but tailorable IT security plan should be in place for the hot standby system.
18、a71 Hardware/Software Infrastructure: Use a commercial-like, multiple-web server front-end to ensure a high level of reliability and operability.a71 Interfaces: Identify mandatory interfaces for compatibility with other support tool sets. Establish interface control agreements as part of MISS develo
19、pment. Interface control testing should verify interoperability.a71 Library Services / Massive File Manipulation and Data Archiving: Co-locate the web servers with standalone archive/library servers if it is deemed necessary to perform frequent massive file upload, download, and manipulation. It is
20、inefficient and time consuming to transfer massive files via the internet.a71 Expect to Customize/Change Management: Experience suggests that no system can meet all potential requirements that may evolve during an investigation. Anticipating the need to customize, the MISS management team must have
