Description
Divide completedCommitted by positive committed for reliability.
Capacity accounting compares available supply with commitments, reservations, or demand. Negative residuals can expose overload while zero capacity requires a distinct undefined utilization state.
Divide completedCommitted by positive committed for reliability.
When to use this tool
Use Commitment Reliability One Period Ratio when you need a transparent resource or workload capacity term.
How to use the tool and how it works
- Enter committed, completedCommitted, unplannedCompleted. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read reliability, totalCompleted. Use the output convention below.
Divide completedCommitted by positive committed for reliability. Add unplannedCompleted only to totalCompleted.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| committed | Committed | Required. Safe integer; minimum 1. |
| completedCommitted | Completed Committed | Required. Safe integer; minimum 0. |
| unplannedCompleted | Unplanned Completed | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| reliability | Reliability | Required. Finite number. |
| totalCompleted | Total Completed | Required. Safe integer. |

}Limitations and assumptions
- Completed committed work cannot exceed commitments; unplanned output does not increase reliability and scope or work size is not evaluated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Validate calendars, skill constraints, and concurrent demand with the actual resource plan.
