Operational Requirements Document

Operational Requirements Document

Select a system of your choice (e.g., aircraft, automobile, Web site, or the service of a bank or restaurant business), and do the following in 3–5 pages:

• Develop the operational requirements document (ORD) for that system.
• Based on the operational requirements, develop the maintenance concept for the system.
  • Construct the necessary top-level operational and maintenance flows.
  • Identify repair policies.
  • Apply quantitative effectiveness factors as appropriate.

As described in the text, effectiveness factors are system requirements that are specified as figures-of-merit (FOMs), such as the following (Blanchard & Fabrycky, 2006):

• Cost or system effectiveness
• Operational availability
• Readiness rate
• Dependability
• Logistic support effectiveness
• Mean time between maintenance (MTBM)
• Failure rate
• Maintenance downtime
• Facility utilization (in percent)
• Operator skill levels

Given the functions that the system you have chosen will perform, how effective or efficient is it? How are these factors related to the mission scenarios? Any flow charts or block diagrams should be pasted on a Word document and not as separate files.
