The result to aim for
Bo&Mie, a Parisian bakery company, had ChatGPT write Google Sheets scripts that calculate daily the production forecasts of its stores from sales, unsold and breaking hours.
What was done
In an interview published by La Tribune des boulangers pâtissiers in March 2024, co-funder Jean-François Bandet explains that each store already followed on Google Sheets the production of the day, the stock remaining at night and the breaking hours of each product. The calculation covers the five establishments and 150 display products; The system works widely alone, with two people to follow it, and the team adjustments during period like Christmas or Easter. According to Him, after one month, end-of-day unsolds had drooped by an age of 25 per cent and breaks by 15 per cent, for an estimated saving of €450,000 out of 2023.Production sheets are calculated on a gram bases and feel to the laboratory every event.
