What do AI productivity
numbers really mean?

15% refers to customer issues resolved per hour.

The 2025 study by Brynjolfsson, Li and Raymond followed 5,172 customer-support agents during an AI assistant rollout. It found an average increase in issues resolved per hour. Effects varied by experience and skill; some experienced workers saw small declines in quality.

40% refers to time spent on assigned writing tasks.

Noy and Zhang’s 2023 randomised experiment involved 453 college-educated professionals. Participants using ChatGPT completed the assigned writing tasks in less time on average. This does not establish a 40% reduction in the cost or duration of an entire business process.

Measure your workflow, including the checks.

Pick one task, collect a representative baseline and agree what correct work looks like. Count review time, corrections, waiting and exceptions. Then compare a small pilot with the same task done without the new tool.

For example, a draft report may be prepared faster while still needing careful verification. The useful outcome is a correct, approved report produced with less total effort.

What we would do with you.

Understand the task, inspect the information available, build a focused pilot and test it with the team. Expand only when the measured improvement and the quality of the result justify it.
