How We Evaluated
Each option was assessed against the six criteria that most reliably predict whether training changes commercial results:
| Criterion | What to look for |
|---|---|
| Documented results | Named clients and specific numbers — not just satisfaction scores |
| Methodology | A named, structured framework your team can reuse after the programme |
| Customisation | Content built around your industry, deal size and buyer profile |
| Cultural range | Proven delivery in India, the Gulf, Southeast Asia and Africa if you sell there |
| Who delivers | The senior expert personally — or a franchise/associate facilitator |
| Reinforcement | A plan for what happens at 30, 60 and 90 days after the workshop |
