How to use the sprint toolkit
The three tools here are deliberately separate. The date calculator answers when, the points converter answers roughly how much, and the definition of done answers what counts as finished. Doing them in that order at the start of a cycle takes about ten minutes and removes most of the arguments that otherwise show up in week two.
- Set the first sprint start and the cadence. Ceremonies land on the first and last working day of each sprint, with refinement near the middle, and they move off weekends and holidays automatically.
- Read the working days column before you commit to anything. A two week sprint is ten working days on paper, and a sprint containing Thanksgiving or Independence Day is not.
- Download the .ics file and import it into your calendar. Every ceremony becomes an all-day event, so nobody has to remember which Tuesday the review is on.
- Enter one to three past sprints in the converter. Use it to sanity check whether a proposed scope fits the hours you actually have, then close it. It is not a productivity measure.
- Edit the definition of done with the team present, print it, and put it somewhere visible. Arguing about the list is the point of the exercise.
Why the working day count matters more than the sprint length
Teams plan in sprints but work in days. Two sprints of the same nominal length can differ by twenty percent of capacity once a public holiday and a couple of days of leave land in one of them. Commitments made against the nominal length and delivered against the real one look like a velocity problem and are really a calendar problem.
What points are and are not
A story point is a statement about relative size: this thing is about twice the work of that thing. It deliberately avoids hours so that estimates survive people working at different speeds. Converting points back into hours undoes some of that on purpose, because a plan eventually has to meet a calendar. Keep the conversion inside the team, keep the range rather than the single number, and redo it when the ratio stops matching reality.
