Check sheet

Kaoru Ishikawa identified five uses for check sheets in quality control:[3] :30 To check the shape of the probability distribution of a process To quantify defects by type To quantify defects by location To quantify defects by cause (machine, worker) To keep track of the completion of steps in a multistep procedure (in other words, as a checklist) When assessing the probability distribution of a process one can record all process data and then wait to construct a frequency distribution at a later time.
