Examples of thresholds include the following:
• Project-wide thresholds could be established to involve senior management when
product costs exceed 10 percent of the target cost or when Cost Performance
Indexes (CPIs) fall below 0.95.
• Schedule thresholds could be established to involve senior management when
Schedule Performance Indexes (SPIs) fall below 0.95.
• Performance thresholds could be set to involve senior management when
specified key items (e.g., processor utilization or average response times) exceed
125 percent of the intended design.
