DBT combined diaries, interviews and a small observed-task exercise. Of 312 submitted diaries, 300 were consented for analysis. Eleven people joined observed exercises, with six Copilot users and five controls across different tasks. Results varied: summarising and writing benefited, while spreadsheets and presentation work exposed speed or quality trade-offs.

Limits and reading context
The small observed sample and limited organisational outcome data cannot establish a general productivity effect. Absence of demonstrated organisational gains is not proof of no benefit. The report's task comparisons used controls; it should not be described as only a self-report survey. Software capabilities and training may have changed since the pilot.
