Projects to do

A small diagnostic lab reviews turnaround, repeat tests and complaints separately, so slow reports and unhappy patients are linked only by guesswork.

A neighbourhood bakery has one oven and limited flour each day, and its most popular product is not always the most profitable use of either.

A marketing head believes a festive campaign works while the finance head doubts it, and both look at the same results yet argue past each other.

A raw survey often hides blanks, joke answers and double submissions that can flip its headline result without anyone noticing.

A new club has limited time to spread its first event, and approaching the wrong people leaves whole circles of students unaware.

A fest committee books artists and stalls before knowing how many students will turn up, so a rainy weekend can leave a hole in the budget.

A coaching class with a full morning batch is tempted to open an evening one, but an empty batch can cost more than the extra income.

A small cloud kitchen hands orders to riders in the order they arrive, so riders cross the same neighbourhood several times for no reason.

A cafe owner can open a second branch now or first run a small trial stall, which costs money but may reveal weak demand early.

A small business can forecast by copying last week, averaging recent weeks or using seasonal patterns, and each method fails in a different way.

A club sends reminders before every event, but nobody knows whether a friendlier message gets more people to sign up than a plain one.

A campus cycle rental with too few cycles loses riders at peak hours, and too many tie up cash and sit idle all afternoon.

A fraud rule that catches most bad payments sounds excellent, yet if bad payments are rare it may flood customers with false alarms.

A snack maker depends on oil, packaging and spice suppliers, and one failure can quietly stop several product lines at once.

A team that checks an experiment every day and stops the moment one version leads will often crown a winner that was only a lucky streak.

A hostel changed its mess timings or a gym changed its slot system, and the manager says complaints dropped, but nobody counted themes before and after.
