Make the calculation reproducible.
In the Portfolio scenario walkthrough, two vacant units at $1,500 asking rent produce $3,000 of monthly exposure. A visible formula is sufficient. A language model would add no value to that arithmetic.
Let language tools assist reviewable work.
A language model may help summarize a bounded set of documents, classify text, or draft an explanation. Preserve the source passages and dates, check consequential claims, and keep unsupported conclusions out of the decision record. Tool selection depends on privacy, access, evaluation, and human review requirements.
Use constraints when resources compete.
A capacity decision needs an objective and explicit limits. The capacity scenario compares all feasible allocations of two products. Changing the objective or available hours changes the chosen plan in a way the visitor can reproduce.
Keep the operating record intact.
Whatever method fits, its output should travel with its inputs, assumptions, limits, reviewer, and intended decision. The model is one component of that system. Acceptance and follow-through give the result somewhere useful to go.
