価値提案（バリュープロポジション）

Value Proposition defines the working concept used to manage value promise. In practice, it helps leaders state why a specific customer should choose the offer instead of an alternative, and it sets a boundary between the customer promise and internal feature inventory. The page should be used as decision support: it names the evidence, trade-offs, owners, and review points needed to avoid describing features without proving why the customer should care.

Value Proposition changes decisions by making customer pain, outcome value, proof, differentiation, and switching cost explicit before teams commit budget, roadmap, sales, or customer resources. It clarifies between the customer promise and internal feature inventory, so teams can decide what is in scope, what is deferred, and what evidence is still missing. For Value Proposition, this reduces rework because teams compare adjacent concepts, record assumptions, and review whether the chosen action changed customer or business behavior.

• Write the customer, problem, outcome, and alternative in one clear statement.
• Support the promise with proof customers can believe.
• Tie value to a buying trigger, not only to a feature.
• Test whether sales, product, and support can all repeat the same promise.
• Revise it when the target or competitive alternative changes.

A workflow tool shifts its value proposition from task storage to reducing handoff delays for operations managers. The team writes the decision boundary, gathers evidence on customer pain, outcome value, proof, differentiation, and switching cost, compares adjacent concepts, and chooses one operating change to test. In the Value Proposition review, the team keeps the parts that changed customer behavior and retires assumptions that were only internally persuasive.

• A slogan is not a value proposition unless it clarifies a customer choice.
• Feature lists do not explain value by themselves.
• A value proposition can be strong for one segment and weak for another.
