Our method
4 weeks.
Not one more.
A method proven across dozens of Power Platform projects. Defined scope, clear milestones, contractual delivery. Here is how it works.
Why 4 weeks
Because the Pareto scope is enough. 80% of the business value sits in 20% of the features. We deliver what serves the business, not what flatters the spec sheet.
Because focus pays off. A team focused for 4 weeks delivers more than a team spread over 6 months. No context-switching, no meetings that drag on, no weekly steering committees.
Because risk must be bounded. 4 weeks is the threshold beyond which budget risk and tunnel-vision become unmanageable. We turn down projects we cannot deliver within that window. We break them into slices instead.
