Content - Assumptions & Constraints.

Best for: The premises section of a proposal or business case, disclosing the assumptions behind a financial model for investment review, agreeing constraints before a project kicks off, and the evidence slide placed right after a numbers slide built on estimates

Use: Use it when a proposal or business plan has to disclose what its numbers and dates depend on. The left column holds assumptions that are still unverified and could move the outcome (repeat rate, hiring pace, flat unit costs); the right column holds constraints already settled and out of scope for negotiation (budget cap, contractual deadline, headcount ceiling, regulation). The typical home is immediately after a financial or schedule slide built on estimates, closing the question of what those numbers rest on before it is asked. Each assumption can carry a verification chip and each constraint a provenance chip, which answers the obvious Q&A question in advance.

Avoid: Use outline-scope-boundary when the split is what the talk will and will not cover: that is the boundary of the presentation, while this is the set of conditions the plan needs to hold. Use problem-risk-matrix to grade risks by likelihood and impact or to pair each risk with a countermeasure, chart-sensitivity-tornado to show how far the numbers swing with each assumption, problem-prior-attempts for solutions already tried and why they failed, cta-next-steps for action items with owners and dates, and cta-approval-signoff when the slide exists to collect an approval signature. If one column has to carry six or more mixed items, the two-column contrast stops reading and the content belongs on separate slides.
