Time and Motion Study

A time and motion study is an observation method used to determine the timing and duration of tasks or procedures.
To collect time and duration data for each step in a process.
1. Determine the level of specificity that you want to measure. Will your analysis be on a highlevel, will it involve great detail, or will it be somewhere in the middle? Then determine your sampling method and assign someone to record the data. An example would be measuring the cycle time for patients scheduled at 11 a.m. and 2 p.m. once a week for each physician in a clinic.
Adds to reliability of anecdotal, incomplete, or unverified data.
Easy to focus on overly "micro" aspects of a task.
Can be time consuming.
