PSP Quality Measures

COQ

A/FR = Appraisal_coq / Failue_COQ

la meta es que sea 2. Dedicarle el doble a Appraisal

Appraisal

Costs are the codest of inspecting for defects.

In PSP: design and code revie

defect prevention

Identificar y resolver causas

failure

Tiempo de compilacion y pruebas

PSP: it is compile and thes time

Defect Removal Leverage

DRL(phase/UT) = (defects/hour for phase_X) / (defects / hour for unit_test)

DRL(phase/UT) is the DRL for phase X with respect to unit test.

the usual base is UT

defects removed per hour by a process step

Yield

PSP review rates

doucments: 4 pags / hour

200 LoC/ hour

Potential Control Parameters

review rate is the most useful to improve Yield

defects found per size unit

defects found per hour

Ex. size units reviewed / hour

Yield (proceso)

Without a name 'process yield' = phase yield beforo compile and test

Process Yield is the % of defects injected before a phas that were found *before* that phase

Yield (for phase)

Defects found / (Defects_found + not_found)
