Projects to do

A tuition centre owner juggles attendance, fee reminders and batch sizes in a notebook and often spots a problem only when a parent calls.

A small hotel gets scattered complaints about rooms, food and staff, and its owner fixes whatever was mentioned most recently.

A canteen manager can count dozens of things, yet only a few of them change what gets cooked, bought or staffed.

Teachers get exam duties by habit, so some end up with long gaps between slots or clashes with their own classes while others rarely serve.

Whether to buy a scooter or rent one depends on use, repairs and resale, and small changes in guesses can flip the answer.

A salon or clinic that records customers by hand ends up with the same person three times under slightly different names and numbers.

You judge a new mess after one good lunch or one bad dinner, which swings your opinion far more than a single meal should.

A kirana owner may buy most of a popular item from a single supplier, so one missed delivery can empty an entire shelf.

A chai stall owner buys milk by feel, so a sudden rise or dip in sales leaves either spoilt milk or lost customers.

A student planning a juice stall near a college gate cannot tell how many cups a day make it worth the effort.

A class group chat is busy, yet the class representative cannot tell whether it is mostly useful notices or noise.

A tiffin service wants to know whether a shorter menu card gets more orders, but changing it for everyone at once makes the result unreadable.

A shop that orders too few umbrellas misses sales in a wet week, while too many sit unsold and tie up money when the rain stays away.

A student planning a trip can pay more for a refundable ticket or less for a fixed one, and exam dates may change at the last minute.

A tailor has limited hours and cloth, and each garment earns a different margin, so stitching whatever customers ask for first may waste the week.

A shop's register is filled in by several people in a hurry, so missing entries and odd values slip in and later reports become unreliable.

A sweet shop sells far more in festival months, so a plain yearly average misleads when ordering stock or hiring extra hands.
