How do you verify that software applies the intended commercial rules?
Connect reviewed terms to explicit inputs and decision logic, test boundary cases, and retain the rule version that actually governed each result.
Translate reviewed terms into explicit decisions
Start with a specific software decision, such as whether an order line qualifies for an agreed price. Identify the governing document version, covered items, units, effective dates and required inputs. Have the responsible commercial owner resolve ambiguities, with legal interpretation handled by qualified counsel where needed.
Microsoft’s purchase-agreement documentation shows how system behavior depends on commitment type, validity period and pricing policy. For example, a configured fixed-price policy can break an order line’s agreement link when the line price changes. Such details belong in the implementation specification.
Separate extracting text from adopting its interpretation and encoding a rule. Keep unresolved meaning out of executable defaults. Record who approved the interpretation and which supported software behavior implements it. Successful document ingestion establishes only that the information entered the system.
Test the rule’s boundaries and interactions
OMG’s Decision Model and Notation provides a language for specifying business decisions and rules, including decision tables. The useful discipline is explicit input conditions and outcomes that business and technical reviewers can inspect together. Using a notation does not establish the legal meaning of an agreement.
Prepare independently reviewed examples at each boundary: before and after an effective date, inside and outside the covered item group, and on either side of a quantity condition. Include missing values, incompatible units and two rules that appear applicable. State the intended outcome for every case.
Check how precedence and exceptions work across the complete decision. A plausible result from one rule may conflict with another condition. Give unresolved combinations a review state and preserve the input values used, so a later correction can identify which decisions require reconsideration.
Reconcile live application when inputs or terms change
Microsoft documents confirmation history for purchase agreements and links to order and invoice lines contributing to fulfillment. Examine what your chosen system records automatically and which actions create history. A configurable feature should be verified in the actual operating process.
Retain the applied rule version with a sample of live decisions. Compare the result with the approved examples and investigate differences in item identifiers, unit mappings, dates or overrides. Recheck affected cases when these inputs change, rather than relying indefinitely on the original setup.
For each revision, identify its intended start, existing work it affects and the person authorized to resolve exceptions. Test the change before wider use and preserve prior results. Software verification should establish faithful application of approved rules while leaving unresolved commercial interpretation visible.
