The economics of automation
· Updated:
Automation can release time without immediately saving cash. A sound calculation therefore separates capacity, the economic benefit actually used and all life-cycle costs.
In brief
Capacity value is an opportunity. Economic benefit arises only where released time converts into cash savings, is used productively or produces another confirmed saving.
Measure released time first
Count transactions, the affected share and minutes before and after the change. This gives the monthly time released. A blanket automation rate is not a substitute for this measurement.
If the new workflow creates more residual work than the current one, it releases no time. That warning belongs in the decision.
Do not count capacity twice
Multiplying released hours by total employer cost gives a capacity value. This value must not automatically appear as a saving.
- Cash saving: a cost actually disappears or is avoided.
- Productively used: the time demonstrably creates other work results.
- Other saving: only specifically confirmed effects are added.
- The cash saving and productive shares may total no more than 100%.
Use TCO, not only the entry price
Total cost of ownership includes one-time and ongoing costs over the same horizon. Depending on the case, operation, monitoring, changes, rollback and vendor updates also belong in the decision.
Compare at least 12, 24 and 36 months. A payback period is meaningful only when monthly net benefit is positive.
Use scenarios, not promises
Use traceable inputs and change only a few assumptions at a time. A conservative, an expected and an adverse scenario make sensitivity more visible.
A calculation is not proof of success. It describes the assumptions under which an initiative could be economical.
