In the production Excel/VBA tool, users entered product specifications through a dynamic form, and the engine automatically applied the decision tables to generate the required UI-component configuration. Follow-up fields appeared according to conditions expressed in a small notation. The roughly 32 KB VBA engine evaluated these definitions alongside the mapping rules. Broad defaults and specific exceptions could coexist in a decision table, using wildcard matching and right-side overrides to give specific cases precedence over general rules. I developed four versions of the tool and included an embedded tutorial for colleagues maintaining the libraries and decision tables. The team could generate configurations through the form and update the shared logic through the libraries after my internship.
