- Reused % is reused size as a percentage of total program size.
- New Reusable % is new reusable size as a percentage of added and
modified size.
- Enter the test and total defects/KLOC or other appropriate measure.
- Enter the planned, actual, and to-date yield before compile.

Program Size - Enter plan base, deleted, modified, reused, new reusable, and total size

from the Size Estimating template.
- Enter the plan added and modified size value (A + M) from projected
added and modified size (P) on the Size Estimating template.
- Calculate plan added size as A + M-M.
- Enter estimated proxy size (E) from the Size Estimating template.
- Enter actual base, deleted, modified, reused, total, and new reusable
size from the Size Estimating template.
- Calculate actual added size as T-B + D-R and actual added and modified
size as A + M.
- Enter to-date reused, added and modified, total, and new reusable size.

Time in Phase - Enter plan total time in phase from the estimated total development

time on the Size Estimating template.
- Distribute the estimated total time across the development phases
according to the To Date % for the most recently developed program.
- Enter the actual time by phase and the total time.
- To Date: Enter the sum of the actual times for this program plus the
to-date times from the most recently developed program.
- To Date %: Enter the percentage of to-date time in each phase.

Defects
Injected

- Enter the total estimated defects injected.
- Distribute the estimated total defects across the development phases
according to the To Date % for the most recently developed program.
- Enter the actual defects by phase and the total actual defects.
- To Date: Enter the sum of the actual defects injected by phase and the
to-date values for the most recent previously developed program.
- To Date %: Enter the percentage of the to-date defects injected by
phase.

Defects
Removed

- Enter the estimated total defects removed.
- Distribute the estimated total defects across the development phases
according to the To Date % for the most recently developed program.
- To Date: Enter the actual defects removed by phase plus the to-date
values for the most recent previously developed program.
- To Date %: Enter the percentage of the to-date defects removed by
phase.
- After development, record any defects subsequently found during
program testing, use, reuse, or modification.

Defect-Removal
Efficiency

- Calculate and enter the defects removed per hour in design review,
code review, compile, and test.
- For DRL, take the ratio of the review and compile rates with test.
- Where there were no test defects, use the to-date test defect/hour
value.
