DATA COLLECTION, ANALYSIS AND DISPLAY 165
Benefits
By establishing the facts about the incidence of failure, a team can plan to
identify the causes of failure and look for ways of removing them. Actions
are taken on the basis of evidence, not feeling.
Checksheets are an excellent way of involving people in quality improvement.
They give a simple method of data collection that can be easily
understood and applied in a wide range of areas.
Example
During an attempt to reduce unauthorized absence from work, a team
collected data on the day of the week that absences occurred. The
checksheet shown in Figure 1 gives the results of the study over a six-month
period. The team used the data in consultation with departmental
managers to crack down on absenteeism.
