Set up a simple To Do / Doing / Done board

Three columns and sticky notes (physical or digital) are all you need to make your work visible at a glance.

Why it works

Invisible work creates two cognitive problems: you cannot accurately assess how much is in progress, and you cannot see which tasks are actually advancing. A visual board externalizes both. The simple left-to-right flow (not yet started → in progress → complete) maps onto temporal progress in a way that makes queues, bottlenecks, and completion rates immediately apparent without requiring analysis. This is an application of distributed cognition: the board thinks for you.

How to do it

1. Create three columns: To Do (backlog), Doing (active work), Done (completed).
2. Write each task on a separate card or sticky note — one task per card.
3. Move cards left to right as work progresses; never move a card backward.

Evidence

Visualization of work state is a core element of both Kanban in manufacturing (where it has strong industrial evidence for throughput improvement) and lean management. Distributed cognition research supports the value of offloading cognitive representations onto physical artifacts. Direct RCTs on personal kanban boards are not available. (mechanistic)

Industrial Kanban evidence does not transfer cleanly to personal knowledge work — production lines have stable, measurable tasks; personal work is more variable and ambiguous.

Common mistake

Creating a board with too many columns (Analysis, Design, Review, Testing, Done) that adds complexity without proportional clarity — three columns is not a starting point, it is the optimal default.
