Sample size selection

[Puneet Vohra]

Hi folks,
 Can you help in defining sample size for time study?
If the total monthly  inflow volume is  5,00,000.
And having  sub processes 5 nos allocated with proportionated volume.
Total headcounts or FTEs are 50.

Hello Puneet

 

For sample size determination, we need a little more information

 

1. What is the purpose of the study?

2. What is the metric under study (e.g. quality, AHT etc) and what difference do we want to detect (e.g. Quality is 90% and we want to detect a difference of at least 5%)?

3. What level of confidence do we need? (we can always work with default of 95%)
