Requirement
The data-analysis platform must allow a new analysis module, such as an NLP step for unstructured social-media data, to be added through defined extension points without broad changes to existing import, visualization, or export modules.
Acceptance Criteria
- Integration effort and blast radius: in a module-integration exercise, a new analysis module that uses the standard module interfaces is connected end-to-end within <= 4 h of engineering effort, while requiring code changes in <= 2 existing modules outside the extension itself; source: exercise report and pull-request diff review; horizon: each major release.
- Compatibility and stability: after integration, >= 95% of the top 20 representative analysis flows using the new module complete successfully, and analysis flows that do not use the new module show <= 2% increase in error rate and <= 5% increase in p95 runtime; source: automated integration suite and benchmark report; horizon: each module-integration exercise.
- User activation and gate: a trained analyst enables the new module in a standard workflow within <= 30 min using product documentation only; if any threshold above is missed, release of the changed extension mechanism is blocked within <= 1 business day; source: usability exercise log and release gate record; horizon: each module-integration exercise.
