(Software) Delivery Performance
delivery lead time
deployment frequency
change fail rate
time to restore service
\Delta t_{lead} = \underbrace{\Delta t_{design} + \Delta t_{validate}}_{\text{hard to measure!}} + \Delta t_{delivery}
\nu_{deploy}
P(fail) = \frac{\sum_{rollback}}{\sum_{change}}
\Delta t_{recovery} = t_{fix} - t_{failure}
lead time
\Delta t_{delivery} = t_{deploy} - t_{commit1}
batch size
reliability
fast
safe
OrganizationalCulture
Westrum Model
Generative
(performance oriented)
- High cooperation
- Messengers trained
- Risks are shared
- Bridging encouraged
- Failure leads to inquiry
- Novelty implemented
Bureaucratic

- Messengers “shot”
- Responsibilities shirked
- Bridging discouraged
- Failure leads to scapegoating
- Novelty crushed
