From the wave-0 evidence ledger
Recorded claims
Each claim states what the inspected source says, at the recorded location—bounded by its scope and graded by its confidence. Nothing here is a synthesis across works.
Across 66 firms and 7,137 workers followed for six months, approximately 80% of treated workers used the tool; among users, the intervention reduced email time by roughly two hours per week and reduced after-hours work.
Scope: Knowledge workers in participating firms over six months; time use rather than output quality or profit.
The study detected no consequential change in the quantity or composition of work tasks beyond individual time savings, an organization-level null that cautions against assuming tool rollout alone produces workflow redesign.
Scope: Measured tasks and six-month window; absence of detected redesign is not proof that redesign cannot occur.
Boundaries
Limitations & independence
Recorded at coding time, carried with the work forever. A claim without its limits is not evidence.
Recorded limitations
- Treatment take-up was incomplete
- Digital-trace measures may miss offline work
- Six-month horizon
- No direct firm financial outcome
- Author/product conflict disclosed
Source independence
Academic field experiment across firms; some authors are Microsoft employees and the intervention concerns a Microsoft product.
