Why multitasking rarely works in everyday work

|Marco Muscarello
Multitasking im digitalen Arbeitsalltag führt oft zu weniger Fokus und mehr mentaler Belastung

You’re listening in a meeting while also drafting a reply to another request. Whether this combination makes sense depends on the demands of both tasks. Rather than banning multitasking outright, here you’ll examine a specific switch.

Your goal for this article

You recognize what information might be lost during a switch and choose between working on tasks one after another, responding when necessary, or arranging an appropriate handover.

Understand: Put the work-related question in context

Not every parallel activity requires the same level of attention. A file transfer running in the background is different from having to assess two matters at the same time. A blanket statement that the brain can never process multiple things at once would be too simplistic.

This article does not derive fixed error rates or time losses from task switching. The WHO describes high work demands and limited control over work as possible risks, among other factors. If frequent responses are part of the role, that needs to be taken into account when organizing the work, rather than simply criticizing personal behavior.

A personal example: A decision and an unrelated question

While a meeting is working toward a decision, you answer an unrelated work-related question. Afterwards, you’re not sure whether the latest change has already been approved. The specific problem is the lack of reliable information, not some general measure of lost concentration.

Clarify the decision first, before continuing on the basis of an uncertain assumption. For future cases, consider whether the unrelated question can wait, whether someone else is responsible, or whether you should openly mention the necessary interruption. Don’t assume you’ll be able to reconstruct the part you missed later.

Decide: Does the switch need to happen now?

The second task can wait

Record it appropriately and return to it at a suitable transition point. Note only what you need to find your place again.

A necessary response cannot wait

Make the switch clear and note where you left off on the first task. A necessary interruption is not a personal failure.

Both tasks require a decision at the same time

Clarify responsibilities, the order of steps, or what support is available. If the requirements are incompatible, silently promising to do both fully will not help.

Describe a transition deliberately

Choose a common combination of activities. Ask yourself what information you need to take in or decide on for each one. Check whether both really need to happen at the same time or whether a clear transition is possible.

If a switch is still necessary, make a brief note of where you left off and record the next step. When you resume, check what information is still outstanding. Follow the established procedures and checks for tasks where professional judgment is critical.

Your switch note

First task: What status needs to be retained?

Second task: Why is a response needed now?

Information: What needs to be checked when resuming work?

Agreement: Who will clarify conflicting simultaneous demands?

Next step: Review the agreement in practice

A suitable sequence can prevent a specific information gap. It does not promise that every task will be completed faster. Check the quality of the transition and whether the required tasks are actually manageable.

Limitations and support

This article offers general guidance on work organization; it is not a health diagnosis or a binding workplace procedure. Follow responsibilities, necessary availability and existing professional requirements. Do not change shared systems and processes without checking their dependencies. Persistently excessive workloads require a decision about scope, resources or support. If symptoms persist or significantly affect daily life, seek appropriate health care.

Frequently asked questions

Is all parallel work wrong?

No. The requirements of different tasks vary. This article addresses situations where attention and judgment are required at the same time.

Can I ignore urgent requests to follow a focus rule?

No. Necessary responses and professional requirements should be taken into account; conflicting demands need to be clarified.

How much time do I lose with each switch?

This article does not provide a general figure for this. What matters is the specific task and which information needs to be retained.

The WHO describes job demands and decision latitude. The switching example is practical guidance, not experimental evidence of a fixed performance loss from multitasking.

The practical example and template are practical interpretations, not a scientifically validated program.
