Carlson's Law, attributed to the Swedish economist and management researcher Sune Carlson, states that interrupted work takes longer than continuous work. The principle explains that every interruption breaks concentration and creates a recovery cost. When a person stops a task to answer a call, read a message, handle a request, or switch to another subject, time is lost not only during the interruption but also when the person tries to return to the original task. Carlson's Law is therefore a key idea in productivity, attention management, and project management.
Meaning for project work
In project management, Carlson's Law shows why uninterrupted work periods are necessary for tasks that require analysis, writing, negotiation, budgeting, scheduling, or creative thinking. Frequent interruptions can extend task duration and increase the risk of errors. A project manager may appear busy all day while making little progress on critical work because attention has been fragmented. Managing interruptions is therefore not a minor comfort issue. It is a technical condition for efficiency and quality.
Relevance in wedding and event planning
Wedding planners and event managers face constant interruptions: supplier calls, client messages, venue questions, administrative requests, design revisions, guest changes, and urgent logistical issues. During the planning phase, this can prevent deep work such as building a budget, reviewing contracts, producing a timeline, or designing a guest flow. On the event day, interruptions are unavoidable, but they must be managed through clear roles and escalation rules. Not every question should reach the lead planner at the same time.
Practical application
Professionals can apply Carlson's Law by grouping similar tasks, defining communication windows, turning off non-urgent notifications, and reserving focused time for high-value activities. A planner may answer supplier emails twice a day instead of continuously, schedule client calls in specific blocks, and protect time for contract review or retroplanning. During an event, assistants or coordinators can filter requests so the project lead remains available for critical decisions. Carlson's Law helps professionals understand that attention is a resource. Protecting that resource improves speed, reliability, and the quality of the final event.
