Tracking progress helps — especially when you write it down
Across 138 randomized studies, monitoring goal progress improved attainment, with bigger effects when progress was recorded and shared.
The short version
Checking how you are doing against a goal is not just bookkeeping: it is one of the mechanisms that turns a goal into action. Across 138 randomized studies, interventions that got people to monitor their progress more often also helped them reach their goals, with a small-to-medium effect. The effect was larger when progress was physically recorded, and larger again when it was reported to someone else or made public.
What the researchers did
Benjamin Harkin, Thomas Webb, Paschal Sheeran and colleagues searched for every experiment that randomly assigned people either to an intervention designed to make them monitor their goal progress or to a comparison condition. To be included, a study had to report two things: whether the intervention actually increased how often people monitored their progress, and what happened to goal attainment afterwards. They found 138 such studies with 19,951 participants in total, and combined them in a random-effects meta-analysis.
Most of the studies came from health: diet, physical activity, blood pressure, smoking and similar goals, where keeping a diary or log is a common intervention.
What they found
- The interventions worked on monitoring. People prompted to track progress did so far more often than controls (d = 1.98).
- Monitoring improved goal attainment. The average effect on actually reaching the goal was d = 0.40, conventionally a small-to-medium effect.
- More monitoring explained the benefit. The increase in how often people monitored their progress statistically mediated the improvement in goal attainment.
- How you monitor matters. Effects were larger when the information was physically recorded rather than just noted mentally, and when the outcome was reported to others or made public.
Limits and caveats
Because most of the studies concerned health behaviours, the size of the effect for work goals or focus is an inference, not a measured result. The studies were also very varied in what they asked people to monitor and for how long, so d = 0.40 is an average over quite different interventions. And "made public" covers a range of things, from telling a researcher to sharing with a group; the meta-analysis cannot say which form of sharing works best.
What it means for how you work
Time tracking is a form of progress monitoring, but the benefit comes from looking at the record, not just producing it. A short weekly review — what you planned to spend time on versus where the hours actually went — is the part that does the work. Writing the result down, rather than glancing at a total, and sharing it with a colleague, client or accountability partner should strengthen the effect further.
Monitoring pairs naturally with planning: an if-then plan sets the goal up, and tracking tells you whether it is working.
