The sampling analysis is a statistical method that quantify the different activities of an operator. When activities are labeled as "added value" or "non added value", it gives you the red/green scheme. This app facilitate the implementation of this method: - note your observations by a simple "tap" - see the graphs being constructed in real time - export your data in Excel ! - save as many configurations as needed Sampling analysis is often a teamwork : once you've created a configuration, you can send it by mail to the colleagues of your who have the same app ! Summing-up the results will be a lot easier ! Activity Sampling is used in the industry (Lean Manufacturing) and services, and also for specialized education (quantification of language improvement,...).
