What has to be true before you buy
- 01The friction is genuinely at demand generation. Buying at the wrong stage moves the bottleneck, it does not remove it.
- 02Ownership varies by company. Customer Support, Sales, Revenue Operations or Marketing can own this. Whoever it is owns the outcome, not just the licence. Unowned tools are adopted for a quarter and then quietly turned off.
- 03A human still signs off on the output. Write down who that is and what they are allowed to reject before rollout.
- 04Adoption level 2 of 5. Level 1 is one tool and no workflow change. Level 5 is an agent running the work with a human auditing it.
- 05The vendor does not publish pricing. Ask for the billable unit, the overage rate, and the cap in writing before you sign.
- 06We found a minimum of 3 published case studies for this tool. There may be more we have not found. Read the sample size and the baseline before you quote any number.
