Are longer working hours a sign of greater productivity? As AI transforms the workplace, businesses need to focus less on time spent and more on how working hours are used, which activities create value, and where processes can be improved.
An American living in Germany once described the cultural difference in a simple way: in the United States, people live to work, while in Germany, people work to live well. This observation highlights a fundamental question for modern business management: Should employee performance be measured by hours worked or by the activities and results those hours produce?
David Valdes, who moved from San Francisco to Munich and works at Google, described these contrasting attitudes toward work in an interview with Süddeutsche Zeitung. While work often plays a central role in professional identity and social status in the United States, employees in Germany tend to place greater emphasis on integrating work into a balanced life.
Working-hour statistics may appear to support this distinction. According to the OECD figures cited in the original article, annual working hours averaged 1,332 per employed person in Germany and 1,800 in the United States in 2025. However, longer working hours do not automatically indicate greater productivity, just as shorter hours do not necessarily mean lower performance.
An hour is simply a unit of time. It tells us how long someone worked, not what they accomplished.
Why Tracking Activities Matters More Than Tracking Hours
Businesses have long recorded attendance, working hours, breaks, holidays, and overtime. Yet many still struggle to understand how employees actually spend their time.
How much time goes into client projects, administration, meetings, research, development, or support? Which activities create value, and which consume resources without delivering proportional benefits? Where could automation eliminate repetitive tasks, and which projects consistently exceed their budgets?
Without answers to these questions, companies may know their employees' working hours without truly understanding their work.
Consider a developer who automates a process that previously required ten hours every week, completing the automation in just five hours. This is not a sign of reduced effort. It is a measurable productivity improvement.
The same principle applies to consultants who solve problems faster through experience, professional firms that streamline administration, and teams using artificial intelligence (AI) to accelerate research and documentation.
True productivity comes from creating greater value with the time available—not from consuming more hours.
How AI Is Changing Employee Productivity Measurement
Artificial intelligence makes this distinction increasingly important. Tasks such as drafting content, summarizing documents, analyzing data, generating code, and researching information can now be completed significantly faster.
However, businesses that measure performance primarily by hours worked risk penalizing their most efficient employees. If someone completes a task in two hours with AI instead of four hours without it, traditional time-based metrics may make that employee appear less busy, even though productivity has improved.
The time saved could instead be invested in customer service, innovation, quality improvements, professional development, or additional projects.
To realize these benefits, companies need visibility into which activities consume time, where efficiency gains occur, and how saved capacity can be used effectively.
From Time Tracking to Activity Tracking
Modern time tracking should go beyond recording how many hours employees work. It should help businesses understand which activities fill those hours, which are necessary, which create value, and which could be simplified or automated.
This is where activity tracking becomes a practical management tool.
With timespin, employees can track their activities using a physical dodecahedron-shaped timer. Each side can represent a specific project, client, or task. When employees switch activities, they simply turn the cube to the corresponding side, allowing them to record their work without repeatedly opening software windows or entering times manually.
The recorded data is automatically synchronized and can be used for reporting, project billing, and controlling project costs.
This straightforward approach makes activity changes easier to capture as they happen, providing businesses with a clearer picture of how working time is distributed.
Activity Tracking Should Improve Processes, Not Monitor Employees
Detailed activity tracking must not become a tool for judging every minute of an employee's day. Its real value lies in identifying patterns and opportunities for organizational improvement.
If a developer spends too much time on administration, the problem may be inefficient internal processes rather than individual performance. If a project repeatedly exceeds its estimated development hours, the cause could be inaccurate budgeting, incomplete specifications, or underestimated coordination requirements.
Similarly, if consultants spend excessive time documenting their work, automating documentation may be more effective than simply asking them to work faster.
Activity data should be treated primarily as process data. Used responsibly, it helps employees and managers identify bottlenecks, improve workflows, and make better-informed decisions.
Why Project-Based Businesses Need Greater Transparency
Activity tracking is particularly valuable for agencies, law firms, software companies, consultancies, engineering firms, and technical service providers, where employee capacity is a significant business resource.
If a project budgeted for 200 hours ultimately requires 320 hours, the additional effort creates a financial challenge regardless of how hard the team worked. In fixed-price projects, every additional hour can reduce profit margins rather than generate additional revenue.
Accurate activity data supports project cost analysis, budget-versus-actual comparisons, and more reliable future estimates. Through integrations such as REST APIs and data exports, these records can also be transferred to existing ERP systems, accounting platforms, and industry-specific software.
The result is a stronger foundation for project management, cost control, and operational planning.
The Future of Work Is About Value, Not Hours
As businesses navigate AI adoption, skills shortages, remote work, and changing expectations around working hours, focusing exclusively on whether employees work 35, 40, or 45 hours a week is no longer sufficient.
Companies first need to understand what happens during those hours.
The most productive organizations will not necessarily be those that encourage employees to work longer. They will be those that understand where resources are being used, which activities create value, and where better processes or technology can eliminate unnecessary effort.
Ultimately, work ethic should not be measured by how long someone sits at a desk. It should be reflected in how responsibly and effectively people use their time.
The question businesses should ask is no longer simply, How long did we work?
It is: What did we work on, what did we achieve, and was the time invested worth it?
In an economy increasingly shaped by artificial intelligence and productivity pressures, answering that question will be far more valuable than measuring who arrives at the office first or leaves last.
