3.7SBTM vs Ad-Hoc Testing
| Aspect | SBTM | Ad-Hoc Testing |
|---|---|---|
| Structure | Charter + time box + notes | None |
| Reproducibility | Session notes allow reconstruction | "I found this bug somehow" |
| Accountability | Metrics show coverage and effort | No visibility into what was tested |
| Skill development | Debriefs improve technique over time | No feedback loop |
| Management reporting | Session counts and bug rates | "We tested for two days" |
SBTM does not constrain creativity — it channels it. The charter gives direction without dictating every step.
