What the spreadsheet misses
- Sécurité
- Dull, dirty and dangerous tasks are where robots most often pay off beyond cost.
- Qualité
- Robots repeat; people adapt.
- Flexibilité
- The more the job changes week to week, the more a person is worth.
- Edge cases
- List the exceptions before you buy; they are usually the expensive part.
- Customer experience
- Ask customers, not vendors.
- Jobs and redeployment
- Plan redeployment and training first; it decides whether staff help or hinder.
- Réglementation
- Machinery, privacy and sector rules vary by country.
