It depends on where the project starts and which dependencies are still unresolved, so the planner builds a range rather than a fixed duration. Product stage, new tooling, electronics scope, content readiness, revision cycles, testing scope and shipping mode all move the critical path. The site notes that a standard-platform sample often targets 7 to 14 days, while fully custom work receives a schedule after feasibility. Timing is a planning range, not a guarantee.
