A Time Study is a tool to measure problems pertaining to delays, unmet deadlines, lates, etc. This is done by meticulously documenting how long each step in a repetitive task, then finding the variance among the instances.
Step 1. Find how long a step is made per instance. A simple subtraction of end time less start time will do. Other methods include manually timing a task or other tools that can find how long a step is done.

Note: If using Excel, do not mind that the result is in decimals. This is just how Excel stores time data and can be later formatted into time.
Step 2. Consolidate as much results from step 1 as possible.

Step 3 (x): Find the average of the results per step (per row). This is your average actual time duration for that step/row.
Step 4 (y) : Find the lowest value per step (per row). This is your “best possible time”.
Step 5: Calculate the variance. The step with the highest positive variance is considered to be problematic.
