Time tracking

Time tracking is the practice of recording how time is spent across tasks, projects, or activities, either logged manually by starting and stopping a timer per task, or captured automatically by software that observes which applications or websites are active. The resulting log is the raw data behind any analysis of where a person's or a team's hours actually go, as opposed to where they were planned to go.

In professional services, time tracking is primarily a billing and utilization tool, tying logged hours to client invoices and to utilization rates against a target. In personal productivity contexts it is used descriptively, within quantified self tracking, to see how time actually breaks down across categories like meetings, deep work, and admin, which is often surprising compared with a person's own estimate before they started tracking.

Time-tracking data is a common input to Personal KPI and goal tracking reviews, and is distinguished from focus time in that raw tracked time captures duration in an activity but not the quality of attention within it — a two-hour block logged as "writing" may include long stretches of interruption. A well-known pitfall is measurement reactivity: people behave differently, often working in smaller or more deliberate chunks, once they know their time is being logged, which can make early tracking data unrepresentative of normal behavior, distinct from progress tracked against formal OKR targets.
