This answer provides an example of good acceptance criteria for the scenario of integrating Salesforce with the largest online professional network. Acceptance criteria are statements that define the conditions that a solution must meet to be accepted by the stakeholders or users. Acceptance criteria should be clear, concise, testable, and measurable. This answer meets these criteria by stating what a sales rep can do (view current information), where they can do it (in the Lead and Contact records), and how they can verify it (directly).
