How to select as Assessment Sample?

 

 

Random sampling is a technique used in studying a certain population. It's used for purposes like market research and trend analysis. In the context of maturity assessments of processes in business operations, like project management maturity assessment, a sample of staff are selected for interviews, and a sample of projects is selected for document reviews for evidence of compliance. While the size of the sample is usually a proportional ratio to the size of the overall population in the scope of the assessment, and usually the ratio is recommended according to the assessment model adopted, the individual items in a sample should be selected so that the overall sample is as representative as possible for the population under study. The larger the sample, the more representative it would be, and more realistic the resulting findings will be. For project and process maturity assessment purposes, a representative sample should cover all departments and all business lines within scope with weights proportional to staff size of each.
