This talk explains how Scenario Casting enables agile teams to pull together despite diverse ideas and concerns - in three iterative collaborative steps:
1. Find example scenarios of how ideas and concerns affect the domain - strictly in domain language! This provides an initial Scenario Backlog outlining the problem space.
2. Prioritize the Scenario Backlog and agree on scope.
3. Combine the top scenarios into coherent overarching Orientation Scenarios.

Let the agile teams focus on their parts of the Orientation Scenarios over the next iteration(s).

Extended Abstract:
Scenario Casting is a collaborative planning and requirements engineering method that has emerged over the past four years in various Domain-Driven Design projects. It is used intensively with dozens of teams most of them involved in ambitious transformation projects.
Scenario Casting is especially helpful for getting a handle on complex or even overwhelming domains. If your domain feels like this and there are a lot of people involved too, you should give Scenario Casting a try.
Scenario Casting lays the groundwork for focused collaborative modeling sessions using domain storytelling or event storming. It ensures that all relevant points are addressed step by step. Also, it helps to quickly identify your domain's subdomains and determine the people who should be involved.

More relevant scenarios are discovered during collaborative modeling. They all go into the Scenario Backlog and will be considered in future Scenario Castings.
Unlike other concepts that try to scale agile, the Scenario Backlog is strictly limited to DDD's problem space, thus avoiding upfront design and premature planning.
Instead, Scenario Casting sets a common focus in problem space for agile teams by defining Orientation Scenarios. An Orientation Scenario illuminates parts of the problem space very precisely. It defines the actual results that solutions must deliver from a domain perspective - but without prescribing specific solutions. Finding and implementing good solutions remains the responsibility of the individual agile teams!

This talk contains examples from real projects and gives you best practices - so you get a good idea of how to try Scenario Casting yourself!
