Time Obs.Time Observation Sheet
10-Cycle Process Study Form
What is a Time Observation Sheet?
The Time Observation Sheet is the foundation of all standardized work. Before you can build a Process Capacity Sheet (Form 1), a Standardized Work Combination Table (Form 2), or a Standardized Work Chart (Form 3), you need accurate time data. This form is where you collect it — by observing the actual work and recording times for each element across 10 cycles.

What is a Time Observation Sheet?
The Time Observation Sheet is the foundation of all standardized work. Before you can build a Process Capacity Sheet, Combination Table, or Standardized Work Chart, you need reliable time data. This form captures 10 observation cycles for each work element, letting you identify the lowest repeatable time — the basis for a sustainable standard.
Unlike a simple stopwatch average, the time observation method looks for the lowest time that the operator can consistently achieve. Outliers — caused by fumbles, missing parts, or abnormalities — are flagged but excluded from the repeatable time. This gives you a standard that is both achievable and challenging.
When to use this tool
Use the Time Observation Sheet at the start of any standardized work study, after a process change, or when investigating a gap between expected and actual cycle time. It is the data-gathering step that precedes all analysis.
