10% time
Definition
A workplace practice where employees allocate approximately 10% of their working hours — roughly half a day per week — to self-directed projects, experimentation, or learning outside their assigned work.
10% time (sometimes called 20% time, depending on the organization) is rooted in the idea that scheduled slack produces disproportionate returns. Google famously used a 20% time policy in its early years, citing Gmail and Google News as products that emerged from it. The principle is: mandate exploration, and innovation compounds.
How it typically works: Some organizations block a specific recurring calendar slot — Friday afternoons, for example. Others track it as a percentage of sprint capacity. The key is that the time is protected, not subject to sprint scope changes or manager override.
What teams do with it: Build internal tools, explore new technologies, write blog posts, prototype product ideas, contribute to open source, or tackle technical debt that never makes it to the backlog. The common thread is self-direction — the individual chooses the project.
The whiteboard dimension: 10% time projects often start with a whiteboard brainstorm — someone with half a Friday and an idea sketches it out before writing a line of code. These boards capture early-stage thinking that's easy to lose. Snapping them with BoardSnap creates a timestamped record of the idea's origin, useful later when a prototype becomes a feature.
Tension with throughput metrics: Teams measured purely on sprint velocity often see 10% time as a tax. The counterargument is that the compounding benefit of exploration and learning shows up in velocity over quarters, not sprints.
Examples
- An engineer uses 10% time to build an internal Slack bot that cuts a recurring manual process from 2 hours to 5 minutes — the bot is later adopted org-wide.
- A designer uses their 10% time to prototype a feature that becomes the next quarter's top-priority roadmap item.
- A product team formalizes 10% time as a standing Friday afternoon block and shares BoardSnap summaries of their exploration whiteboards in a dedicated Slack channel.
- A startup CEO reserves 10% time for learning — reading, taking courses, attending meetups — and treats it as non-negotiable overhead.
