PSP2 Plan Summary Instructions

Purpose To hold the plan and actual data for programs or program parts.

General - Use the most appropriate size measure, either LOC or element

count.
- “To Date” is the total actual to-date values for all products
developed.
- A part could be a module, component, product, or system.

Header - Enter your name and the date.

- Enter the program name and number.
- Enter the instructor's name and the programming language you
are using.

Summary - Enter the added and modified size per hour planned, actual,

and to-date.

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 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 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 - 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.
