In my current company, DSDM is being practiced.
For a new project that we are starting, there are no backlogs yet and it is decided we will be executing the project in sprints.
The duration of the project is about 3-4 months.
In this scenario, I believe using a different sizing (T-shirt sizing) should suffice. I dont see a value in using story point estimation in this type of situation; eg. no velocity calculation required to forecast our deliverable for future or to calculate our productivity for the sprints.
The management would want to continue with Story points.
Please let us know how I can continue sizing stories.
