Most forecasting courses hand you a clean dataset. This one does not.
You start with four spreadsheets pulled from a real operations team: overlapping date formats, a column that changed meaning halfway through the year, and two hundred rows somebody typed by hand. Getting from there to a forecast anyone will trust is the actual skill, and it is the one nobody teaches.
By the end you will have built a working forecast, written the assumptions down where a manager can read them, and defended the number in a review session with your mentor.
