Requirements Gathering - Writing User Stories
Writing user stories ranks at the top of critical project tasks. When the customer writes user stories, business subject matter experts (SME) sit down with the Scrum team to lay out user requirements – what the user community needs from the Anaplan platform, so they can follow the business process. For example, a customer may be using the Anaplan platform to improve their sales forecasting process. The team needs to discuss all upstream and downstream processes within the sales forecasting process that Anaplan will impact.
