What may NOT be decided during the INCEPTION stage of a Disciplined Agile project?

In the Inception stage of a Disciplined Agile project, teams focus on understanding the project context, defining the high-level scope, and establishing foundational elements necessary for successful project execution. While all the other options, such as test strategy, initial architecture, and high-level scope, can be discussed and decided upon during this stage, deployment strategy generally requires a deeper understanding of constraints and requirements that are often developed later in the project lifecycle.

The development of a deployment strategy typically involves detailed discussions around infrastructure, operational readiness, and release processes that are more effectively addressed during later phases of the project when the teams have more concrete information and insights derived from iterative development and testing. Therefore, decisions regarding deployment strategy are reserved for later stages when specific requirements and contexts are better understood, allowing for a more informed decision-making process.
