CHECK SHEET • A check sheet is one of the seven basic quality tools. Data collection can often become an unstructured and messy exercise. It is a simple form you can use to collect data in an organized manner and easily convert it into readily useful information. • The function of a check sheet is to present information in an efficient, graphical format. • A check sheet is a table or a form used to systematically register data as it is collected. • Check sheets help organize data by category. They show how many times each particular value occurs, and their information is increasingly helpful as more data are collected. • Main applications of a check sheet include registering how often different problems occur and registering the frequency of incidents that are believed to cause problems.
Purpose It facilitates the collection and analysis of data. When to Use a Check Sheet • When data needs to be collected repeatedly by the same person or at the same location. • When one needs to collect data on the frequency or patterns of events, problems, defects, defect location, defect causes, etc. • When one needs to collect data from a production process.
Benefits of Check Sheet • Collects data with minimal effort. • Convert raw data into useful information. -Translate opinions of what is happening into what is actually happening. One can talk on the basis of data points which have been gathered.
5 Basic types of Check Sheets: • Classification: A trait such as a defect or failure mode must be classified into a category. • Location: The physical location of a trait is indicated on a picture of a part or item being evaluated. • Frequency: The presence or absence of a trait or combination of traits is indicated. Also number of occurrences of a trait on a part can be indicated. • Measurement Scale: A measurement scale is divided into intervals, and measurements are indicated by checking an appropriate interval. • Check List: The items to be performed for a task are listed so that, as each is accomplished, it can be indicated as having been completed.
Uses of Check Sheet • Clearly identify what is being observed. The events being observed should be clearly labeled. Everyone has to be looking for the same thing. • Keep the data collection process as easy as possible. Collecting data should no become a job in and of itself. Simple check marks are the easiest. • Group the data. Collected data should be grouped in a way that makes the data valuable and reliable. Similar problems must be in similar groups. • Be creative. Try to create a format that will give you the most information with the least amount of effort.
Advantage of check sheet • Effective way of displaying data • Easy to use • Can identify the root cause of a problem • A first step in the construction of other graphical tools • Provides a structure for uniform data collection • Can be used to substantiate or refute allegations
