A packaging machinery firm books four large orders in one quarter. The owner hires three fitters and a wireman on the strength of them. Two orders then slip by half a year while the customers finish their new buildings. When those machines are finally needed, one new fitter has gone and the wireman has sat idle for months. Then a burst of small retrofit orders arrives, and it needs programmers, not fitters.
Our page on machinery builders suggests planning headcount by skill group against the order book. This guide sets out how to do that with figures most builders already have.
Why headcount and orders drift apart
- Orders are counted in rupees and machines, while capacity lives in hours of particular trades.
- Delivery dates move with the customer's plinth and civil works, a delayed power connection or a stalled bank loan.
- Every model draws on a different mix: a conveyor is heavy on welding, a crane on girder work and proof-load testing, a filling machine on wiring and software.
- Machines already shipped keep drawing service and commissioning hours for months.
- Hiring takes far longer for some trades than for others, so late decisions bite unevenly.
From orders to hours by skill group
Start with standard hours per model, by trade. Past job cards or a foreman's estimate for each model are enough to begin. Adjust for heavy options, such as an extra servo axis, a stainless frame or a vision inspection station. Spread the hours across the quarters in which each trade works on the build. Then add field load: installation, commissioning and warranty visits for machines already out of the gate.
Capacity is productive hours, not names on the roll
- Start from paid hours per person per quarter.
- Subtract leave, holidays, training and the usual absence.
- Subtract travel days for anyone who goes to site.
- Subtract a realistic share for rework, waiting and meetings.
- Count apprentices and new joiners at part value until they are signed off.
- Keep field engineers as a separate group, since their hours rarely help the shop.
Building the plan, quarter by quarter
- 1
Sort the pipeline into three buckets
Confirmed orders, likely orders where the customer is negotiating terms, and possible enquiries still at quotation. Plan firmly on the first, prepare for the second, and watch the third.
- 2
Convert each bucket into trade hours
Use standard hours by model and spread them by quarter. Keep the buckets apart so the owner can see how much of the load is still a hope.
- 3
Set the hours against capacity
For each trade and quarter, compare hours needed with productive hours available.
- 4
Read the gaps by shape
A short spike in one quarter differs from a shortfall that persists. A gap only in the possible bucket is not yet a gap.
- 5
Pick a lever for each gap
Overtime for a brief spike. Cross-skilling where a neighbouring trade has slack. Job shops for fabrication or machining that is not your edge. Hiring for a shortfall that repeats.
- 6
Set hiring triggers by lead time
A helper can be found in weeks; a PLC engineer or a senior fitter may take months. Decide when each trade's hiring must start for people to arrive in time.
- 7
Refresh the plan monthly with sales
Move orders between buckets, update dates and rerun the comparison. A plan refreshed only at budget time is wrong by the second quarter.

The plan depends on sales sharing the pipeline honestly and early. Ask for a short monthly update: what moved bucket, what dates shifted, which enquiries are new. Show sales the trade gaps in return. A salesman who sees that controls are booked solid for two quarters will quote a realistic date on the next automation-heavy order.
Where to begin
Take this quarter's confirmed orders, estimate hours for three trades only, and compare them with productive hours. Often a single sheet exposes the binding trade. The weekly view of the same problem sits in idle and overloaded build cycles. Two business types show it in practice: planning for SPM builders, then planning for conveyor makers, where site erection adds its own load. A blank manpower sheet helps, and workforce planning support can build the full model with you.
