Equipment buying & work planning
Equipment Investment: Seven Costs to Include in the Business Case
A purchase can improve a process without producing the savings shown in a sales brochure. Build the business case from the facility's own workload and records.
- Define equivalent work
Use the same tasks and period.
- Collect actual costs
Separate quoted, observed and estimated inputs.
- Test lower use
Expose assumptions that drive the result.
- Present the evidence
Keep scope, exceptions and uncertainty with the decision.
Build the business case around equivalent work
Compare acquisition, installation, training, maintenance, energy, downtime and end-of-life costs over the same period. State which tasks each alternative can actually perform. Equipment with a lower purchase amount may require different foundations, accessories, storage or handling arrangements. Excluding those differences makes the financial comparison look more precise than the underlying scope allows.
Estimate use from scheduled work rather than hours the equipment is available. Record task frequency, setup time and conflicts with other departments. Separate supplier information from site estimates. A machine capable of a fast cycle may still be used infrequently because the work depends on access, staffing or upstream supply.
Test uncertain savings before committing capital
Use distinct measurements for labor, damage, rework and waiting. Avoid counting one event twice: reduced waiting already reflected in cycle time is not an additional labor saving. A hypothetical payback calculation is useful only when its assumptions remain visible, including demand, service costs and the proportion of work the proposed equipment can cover.
Compare a normal-use case with lower utilization or changed demand. Include inspection, parts access and support responsibilities in the quotation review, and treat resale value as an assumption rather than a guaranteed credit. Management can then see which facts support the purchase and which uncertainties could change the decision.
| Input | Preferred evidence | Common error |
|---|---|---|
| Utilization | Representative tasks and expected frequency. | Available hours treated as productive use. |
| Operating cost | Quoted requirements and site-specific estimates. | Different workloads used for competing options. |
| Avoided loss | Distinct observed delays, rework or damage events. | The same benefit counted under several headings. |
| Uncertainty | Normal and conservative scenarios. | An ideal return presented as a guaranteed outcome. |
Review checklist
- Expected annual use
- Service and spare-parts plan
- Sensitivity to lower demand
Buyer questions
Should the lowest purchase price win?
Only after comparing installation requirements, operating costs and the equipment's ability to perform the same task.
What should we do with uncertain savings?
Show them separately or test a conservative scenario rather than presenting them as guaranteed benefits.
Should a business case use the supplier's productivity percentage?
Treat it as a claim to investigate, not as a site result. Ask what task and conditions support it, then compare with representative local work. Include setup, replenishment and downstream effects so the calculation does not assume an improvement in one step applies to the whole process.
How should warranty terms enter the cost comparison?
Review what is covered, for how long and which service or use conditions apply. A warranty period alone does not establish uptime, maintenance cost or task suitability. Keep warranty scope separate from estimated operating benefits and include any internal support the facility must provide.
