Editorial draft available to read. Factual and language review is pending. Examples are illustrative.
Decision and scope
Frequently changing commercial rules need controlled configuration. Identify the parameters, allowed ranges and effective dates that business owners genuinely manage. Do not turn every piece of application logic into an option: invariants protecting consistency still need a clear definition and reliable checks throughout the system.
Illustrative example
Illustrative example: a company changes payment terms for selected customer segments. An administrator prepares a new table, compares representative quotations and schedules its effective date. Existing quotations retain the rule version used when they were calculated, while new quotations use the applicable published version.
Acceptance check
Test incompatible values, overlapping effective periods and reversal of a mistaken publication. Require appropriate review for changes affecting amounts or approval authority. Accept the configuration when authorized people can update it without editing code and historical results still have a reproducible explanation.
Key takeaways
- Accept the configuration when authorized people can update it without editing code and historical results still have a reproducible explanation.
