Two orders offer similar profit, but one occupies the company's constrained machine for much longer. Accepting it may displace several smaller jobs with a better combined contribution. The order is profitable in isolation and still costly as a capacity choice. Commercial planning becomes more useful when it connects margin with the resource that limits the business's ability to deliver.
Find the real constraint
The scarce resource might be equipment time, a specialist employee or a limited delivery slot. It can move as the operation changes. Management should understand the current constraint before using a simple unit-margin comparison to prioritise work, because the same order can have different commercial value when capacity is abundant than when it prevents another customer from being served.
Compare relevant contribution
The analysis should focus on the costs and capacity affected by the decision, with finance and operations agreeing the basis. A broad average cost may obscure the incremental choice. This is a management discussion rather than a substitute for full financial assessment, helping the team understand why an apparently attractive order may not be the best use of a genuinely scarce operating period.
Keep the relationship in view
A lower immediate contribution may still support an important long-term customer or strategic capability. Those reasons should be explicit rather than hidden inside an inaccurate margin calculation. The enterprise can then make a deliberate trade, recognising the commercial relationship value while understanding what it gives up in near-term capacity and contribution to honour that choice.
Use the insight selectively
The approach is most useful where the resource is actually constrained. Applying it mechanically to every order can add complexity without improving decisions. A business gains when it knows which operating limit matters and uses that knowledge to coordinate sales and scheduling, ensuring that accepted work reflects both customer value and the finite capacity required to deliver it.
