The whiteboard on a Monday
Four vessels, two filling lines, three people who can compound. This week: two batches of a white cream, a clear gel, a coloured balm and a brand client's shampoo. The planner draws it on the whiteboard. On Tuesday, a raw material is late, the balm moves, and suddenly the coloured balm is followed by the white cream in the same vessel, which means a full clean. The filling line is booked for a batch that is not made yet.
By Wednesday the whiteboard is a mess of arrows and the compounders are asking what is next.
Too many constraints for a whiteboard
Scheduling cosmetics production is a puzzle with several interacting pieces. A whiteboard can show the plan but cannot tell you when a change breaks something.
- Vessels have different capacities and some products can only be made in certain vessels.
- The cleaning needed between batches depends on what came before, and what follows, under your own rules.
- Making and filling are planned separately, so bulk waits or the filling line waits.
- Staff skills and availability limit what can run at once.
- Raw material and packaging availability is not checked on the board.
What clashes cost
Unnecessary cleans take vessels out of use and use water, chemicals and time. Bulk that waits for a filling slot ties up vessels or containers. Last-minute changes confuse the team and increase the chance of mistakes. And the planner spends much of the week rearranging the board.
Brand clients feel it as moving dates, which is the last thing you want when they are planning a launch.
There is also a hidden capacity question. When the schedule is on a whiteboard, nobody can say with confidence whether next month has room for a new brand client's first production run. The answer given is usually optimistic, and the squeeze arrives later.
A scheduler built around your vessels and rules
- Each vessel and filling line is set up with its capacity, the products it can handle, and its availability.
- Your cleaning rules are recorded: which product changes need a full clean, which need a rinse, and how long each takes. We record your rules, not ours.
- Batches to make come from orders and stock requirements, each with its size, product and due date.
- The scheduler proposes a sequence per vessel that meets due dates, respects capacity, and groups similar products to avoid unnecessary cleans. The planner can drag and adjust.
- Filling is scheduled against making, so each batch has a filling slot when it is ready, and bulk hold times you set are respected.
- Raw material and packaging availability is checked for each batch, and batches missing something are flagged before they reach the vessel.
| Constraint | On the whiteboard | In the scheduler |
|---|---|---|
| Vessel capacity | In the planner's head | Checked for each batch |
| Cleaning between products | Remembered | Applied from your rules |
| Making and filling | Planned separately | Planned together |
| Materials | Checked on the day | Checked when scheduled |
| A change mid-week | Arrows on the board | Knock-on effects shown |
A week that holds its shape
The compounders see a clear list of what is next in each vessel. Cleans are grouped rather than scattered. Filling lines are booked for batches that will be ready. When something changes, the planner sees the knock-on effects before committing and can tell a brand client about any date change early.
Is this your planning?
- The production plan is a whiteboard.
- Vessels are cleaned more often than necessary.
- Bulk waits for filling, or filling waits for bulk.
- Batches are scheduled before materials are confirmed.
- Changes mid-week cause confusion.
