“I asked the team to log where their time goes. Got the reports back: everyone works 8 hours straight, no breaks. Yet the project is 3 weeks behind. Someone is lying — either the people, or our assumptions about what ‘work' actually looks like.”
Nobody is lying. Human memory is simply an unreliable witness. Research shows that people who claim a 70-hour workweek actually work fewer than 50 hours. The rest is consumed by interruptions, context-switching, and the illusion of busyness.
In this article, we'll walk through 7 steps of workday time tracking that produce real data for labor standards — not fiction reconstructed from memory, but precise diagnostics. Based on the methodologies of Drucker, Vanderkam, Cirillo, and Basecamp.
Why “write it down at the end of the day” isn't time tracking
In The Effective Executive, Peter Drucker laid out an axiom that 90% of companies ignore: if we rely on memory, we don't know how time was actually spent. People tend to overestimate time on “important” tasks and catastrophically underestimate time on small things — checking email, chats, “quick” calls.
A workday time log filled out at the end of a shift is not diagnostics. It's a retrospective reconstruction where the brain automatically bends reality to match expectations.
| Tracking Method | Accuracy | Value for Standards |
|---|---|---|
| “Remembered at the end of the day” | ±40–60% | Minimal |
| Logged every hour | ±20–30% | Moderate |
| Logged at each activity change | ±5–10% | High |
| Automatic tracker | ±2–5% | Maximum |
“We compared manual timesheets against automatic tracking data. The gap was 35%. People weren't lying intentionally. They genuinely believed they'd spent 7 hours on the project. In reality — 4.5 hours. The rest was eaten by meetings and Slack.”
The rule: workday time tracking starts with an admission — entries are made at the moment of each activity change, not at the end of the day. Everything else is fiction.
Step 1. Choose your “atomic unit” of measurement
Before launching workday time tracking, decide how granularly you'll record time. The quality of your standardization data depends on this choice.
Option A — 15–30 minute intervals (Vanderkam method). Laura Vanderkam recommends keeping a log over 168 hours (a full week), recording activities every half hour or at every activity change. This gives the complete picture — including “invisible” time spent on transitions, waiting, and micro-tasks.
Option B — 25-minute “Pomodoros” (Cirillo method). Francesco Cirillo proposes measuring not time but effort — in 25-minute blocks of focused work. This lets you standardize tasks not in abstract hours but in units of effort: “Writing a report = 4 pomodoros”, “Code review = 2 pomodoros”.
| Parameter | 30-min Intervals | 25-min “Pomodoros” |
|---|---|---|
| What it captures | Time | Effort |
| Accuracy | High for routine tasks | High for project tasks |
| Accounts for breaks | No (must be added separately) | Yes (5-min break built in) |
| Best for | Admin staff, support teams | Developers, designers, analysts |
“We tried both approaches. The 30-minute intervals worked better for accounting — they have lots of routine tasks. For developers, pomodoros worked better, because their work requires deep focus.”
The key point: 8 hours in the office ≠ 8 hours of work. Workday time tracking will reveal this difference immediately — and that's perfectly normal. That's exactly what it's for.
Step 2. Mark “time parasites” in real time
A simple entry like “worked on report — 2 hours” doesn't provide enough data for standardization. Because it's unknown: were those 2 hours of uninterrupted work, or 2 hours with 15 interruptions?
Cirillo recommends marking interruptions during workday time tracking, not after:
- Apostrophe (‘) — internal interruption: felt like checking your phone, getting coffee, browsing news
- Dash (–) — external interruption: colleague stopped by, phone call, Slack message
| Scenario | Total Time | Interruptions | Net Work Time | Actual Standard |
|---|---|---|---|---|
| Report (quiet day) | 2 h | 3 interruptions | 1 h 40 min | ~1.5 h |
| Report (typical day) | 3.5 h | 15 interruptions | 1 h 50 min | ~1.5 h |
| Report (chaotic day) | 5 h | 30+ interruptions | 2 h | ~1.5 h |
The actual standard is roughly the same. The difference is in the environment. This shows that the problem isn't the employee — it's the number of interruptions. Standardizing chaos is pointless — remove the interruptions first, then set your benchmarks.
“Workday time tracking revealed that our project manager receives an average of 23 interruptions per day. A task that should take an hour stretches to three. We didn't ‘fix' the employee — we removed the interruptions.”
Step 3. Categorize time by “initiator” (Oncken method)
For proper standardization, knowing “how much” time was spent isn't enough. You need to know — who initiated that expenditure. William Oncken proposes dividing all recorded time into three categories:
| Category | Typical % (before optimization) | Target % | Examples |
|---|---|---|---|
| Boss-imposed | 20–30% | 15–20% | Urgent requests, ad hoc tasks |
| System-imposed | 30–50% | 15–25% | Meetings, reports, approvals |
| Self-managed | 20–40% | 50–60% | Project work, deep work |
“After a week of workday time tracking, we discovered our developers spend 45% of their time on ‘system noise' — meetings, status reports, waiting for approvals. Less than half the day is spent actually writing code.”
Only self-managed time can be standardized. Everything else needs to be reduced.
Step 4. Run a “sanity cleanse” before standardizing
Drucker insisted: before you standardize, eliminate the unnecessary. You can't set benchmarks for a chaotic process — you'll just bake inefficiency into your standards.
After collecting workday time tracking data, ask two questions about each category of time expenditure:
Question 1: “What happens if this simply doesn't get done?” If the answer is “nothing” — stop immediately. In practice, 10–20% of activities in any company can be eliminated without any consequences.
Question 2: “Could someone else do this?” If the task can be done by a less skilled (and less expensive) employee — delegate it. A senior developer spending time updating Jira tickets is a role standardization problem.
“Time tracking revealed that our team lead spends 6 hours a week filling out reports for three different systems. We automated two of the three — freeing up 4 hours a week for actual work. No new hires needed.”
Only after the “sanity cleanse” is workday time tracking data ready for setting standards.
Step 5. Build in a recovery coefficient
The most common standardization mistake is assuming 8 hours of workday = 480 minutes of continuous productive work. This is physically impossible.
Productivity research points to an optimal rhythm: 52 minutes of work, then 17 minutes of rest. This isn't laziness — it's biology. The brain needs recovery, and trying to fill every minute leads to quality degradation in line with the law of diminishing returns.
| Standardization Model | Calculation | Real-World Result |
|---|---|---|
| “Ideal” (480 min of work) | 8 h × 60 min | 5–6 h of actual work + burnout |
| “Realistic” (with buffer) | 6 h of productive time | 6 h of stable, quality work |
| “Optimal” (52/17) | ~5.5 h of net work | Peak productivity without burnout |
The standardization formula: Standard = Net task time × 1.3 (switching and recovery coefficient)
If workday time tracking shows a task takes 40 minutes under ideal conditions — set the standard at 52 minutes. This isn't “padding for laziness” — it's padding for reality.
Step 6. Calibrate estimates: “forecast vs. actual”
Workday time tracking is not a one-time event — it's a continuous process of closing the gap between how long we think a task will take and how long it actually takes.
Cirillo recommends a specific technique: before each task, write down an Estimate (forecast in blocks), and after — the Actual. After a month, you have a solid basis for accurate standardization.
| Week | Forecast | Actual | Variance |
|---|---|---|---|
| 1 | 4 blocks | 8 blocks | +100% |
| 2 | 6 blocks | 7 blocks | +17% |
| 3 | 7 blocks | 7.5 blocks | +7% |
| 4 | 7 blocks | 7 blocks | 0% |
“After a month of workday time tracking, our task estimates became 60% more accurate. Not because people ‘stepped up' — but because we finally saw how much time things actually take.”
Standardization isn't “set a number and forget it.” It's a living process where time tracking data continuously refines the benchmarks.
Step 7. Bring it all together into a standardization system
After completing all the steps, you have the data to build well-grounded standards. Here's the final structure:
- Net task time — how long the task takes without interruptions (from time tracking data)
- Environment coefficient — a multiplier for the typical number of interruptions (from your marking data)
- Recovery coefficient — ×1.3 as a buffer for switching and rest
- Final standard = Net time × Environment coefficient × Recovery coefficient
Calculation example:
| Parameter | Value |
|---|---|
| Net time (from time tracking data) | 40 minutes |
| Environment coefficient (5–7 interruptions/hour) | ×1.4 |
| Recovery coefficient | ×1.3 |
| Final standard | 73 minutes (~1 h 15 min) |
As the authors of Rework put it: the answer isn't to work more hours — it's to have fewer obstacles. Workday time tracking is the tool that makes those obstacles visible.
Conclusions
Workday time tracking isn't a way to make people work faster. It's a diagnostic that shows where time is being lost and provides the foundation for realistic standardization.
Key takeaways from this article:
- Log time at the moment of each activity change — not at the end of the day
- Choose your unit of measurement: 30-min intervals or 25-min pomodoros
- Mark interruptions — they'll reveal the true standard vs. the chaos
- Categorize time by initiator — “system noise” cannot be standardized
- Run a “sanity cleanse” before setting standards
- Apply a ×1.3 recovery multiplier — people are not machines
- Calibrate “forecast vs. actual” every month
“Time tracking revealed a truth nobody wanted to see: the problem wasn't the people — it was the processes. Once we removed the obstacles, productivity rose on its own. No motivational speeches, no penalties.”

FAQ
How long does time tracking need to run to produce reliable data?
At minimum — one full working week (168 hours, per Vanderkam). For accurate standardization, 2–4 weeks is recommended to capture variation: quiet days, meeting-heavy days, sprint starts and ends. A month of workday time tracking gives a solid enough baseline to set standards.
Won't the team see time tracking as a sign of distrust?
It depends on how it's framed. If the goal is “catching slackers,” expect resistance. If the goal is “identifying obstacles and setting realistic standards so nobody burns out,” the team will get on board. Show early results: time tracking typically surfaces process problems, not people problems.
How often should standards be reviewed?
Quarterly, or whenever significant process changes occur (a new tool, a team restructure, a new type of task). Standards aren't a law — they're a calibrated model that should evolve alongside reality.
