Direct answer
Confirm that operational capacity is exhausted, quantify demand with evidence, then select the least capital-intensive option that meets the requirement with acceptable risk.
When this decision arises
- Orders refused or lead times extending
- Sustained operation at maximum shift capacity
- Contracted or highly probable demand growth
- Competitive risk from unserved demand
- Customers requesting capacity commitments
The options on the table
Operational capacity recovery
Cheapest and fastest; must be exhausted before capital.
Debottleneck
Targeted capital at the constraint.
Additional line
Dedicated capacity where volume is committed.
New site
Where the current site is capped by space, utilities or permits.
Decision matrix
| Option | Capital | Time to output | Demand certainty needed |
|---|---|---|---|
| Operational recovery | Low | Weeks | Low |
| Debottleneck | Moderate | 3–9 months | Moderate |
| Additional line | High | 9–18 months | High |
| New site | Very high | 18–36 months | Very high |

Engineering and project considerations
- Demand evidence quality determines acceptable capital risk
- Time to output matters as much as capital cost
- Utility, effluent and logistics headroom must be confirmed
- Labour availability for additional shifts or a new site
- Financing structure should match the ramp-up cash profile
What to prepare before engaging engineering companies
- Demand forecast with contracted versus speculative split
- OEE evidence showing the operational ceiling
- Site and utility headroom assessment
- Financing options and cost of capital
What to measure
Frequently asked questions
How much demand certainty is enough?
Enough that the downside scenario still services the financing. Lenders assess this explicitly; internal cases should apply the same test.
