Plan a milestone from launch to exit

A milestone is easier to approve when the project owner can describe what a player will do. “Three levels and a save system” leaves major questions open. A more useful account describes entering the game, learning the relevant action, reaching a result, leaving, and returning.

Write the session before the task list

Name the audience and setting. A classroom tablet activity shared between groups needs a reset procedure and facilitator context. A home adventure with longer sessions needs different progress and return behavior. Then describe the primary input and the visible result of an ordinary action.

Choose a starting point and an ending that can be reviewed. A single encounter can include its necessary menu, failure, retry, and completion behavior. Those supporting parts should not vanish from the scope merely because the main mechanic gets more attention.

Separate experiments from production commitments

Record which rules remain uncertain and how a build will help resolve them. Temporary visuals are acceptable when their limitations do not invalidate the test. They are less useful if the question depends on readability, scale, or character motion that the placeholders cannot represent.

List the assets needed for the agreed section. For each, name its supplier, format, approval owner, and readiness date where known. Keep third-party rights questions visible. A missing rig or unclear music license can block a milestone even when its code is ready.

Make acceptance observable

Select ordinary, failure, and return tasks. For a checkpoint encounter, check progress before activation, after activation, after a deliberate restart, and after the relevant interruption. State which settings and world changes should survive. Use the actual target build and record the hardware or browser used.

Design acceptance also needs a responsible person. A technically correct jump distance may still conflict with the intended pace. Allow review of those choices without treating every design revision as a defect in implementation.

Keep changes attached to a build

Feedback identifies the build and moment observed. The owner separates an agreed correction from an additional feature, and the team explains consequential work before adding it. A second input method may require changed prompts, menu navigation, and test coverage as well as a new input binding.

At the end, record what is reusable, what remains experimental, and what the next stage should answer. The brief worksheet, deeper production questions, and scope guide help prepare that discussion.
