Business Rule Extraction Agent: what goes in, what the agent does and what you get

What it does

When a legacy system is replaced, nobody can say what it really does, such as why some orders skip approval or how a discount is capped. This agent reads the code, stored procedures, old specs and manuals and lists each rule in plain words with where it was found. For each rule, it builds sample data that should trigger it and runs the data through a test copy of the system to see if the rule really holds. Rules that do not behave as written are flagged. For unclear or conflicting ones it drafts a question for the right stakeholder and waits for the answer. After each reply it updates the rule catalog and retests. The analyst approves the catalog. Edge case: code says discounts cap at 15 percent, but the system applies 20 percent for one customer group.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

A rule is confirmed when a test shows the system behaves as the rule says and a stakeholder agrees it is correct.

  • Mark a rule as mismatched if the test result differs from the code
  • Ask a stakeholder when two sources conflict
  • Never retire a rule without an owner's confirmation
  • Group rules by process area

Make it yours

An example run

What happensIn an order system, code capped discounts at 15 percent. The agent ran 12 sample orders and found wholesale customers got 20 percent. It marked the rule as mismatched and asked the sales manager. She said 20 percent was an old deal for wholesale only. The agent split it into two rules, retested with 6 orders, and the analyst approved.
