Check Sheet Implementation Utilizing Check Sheets to Improve Quality
Contents • Check Sheets Defined • Brainstorming Exercise • Creating Check Sheets • How they work Benefits/Problems • Real World Example • Practice Exercise
Check Sheets Defined • What is a check sheet? • A basic tool for monitoring quality improvement processes • A simple data collection device • There are two varieties of check sheets • Tabular Example • Schematic Example1
Check Sheets Defined • Common Types • Distribution Check Sheets • Used to collect data in order to determine how a variable is dispersed within an area of possible occurrences • Location Check Sheets • Highlights the physical location of a problem/defect in order to improve quality • They may also utilize visual(schematic) drawings of areas in order to record where problems are occurring
Check Sheets Defined • Common Types, Continued • Cause Check Sheets • Used to keep track of how often a problem happens or records the cause to a certain problem. • Classification Check Sheets • Used to keep track of the frequency of major classifications involving the delivery of products or services
Optional Brainstorming Exercise • Creating a Check Sheet • In groups of three to five people, brainstorm a simple process, which can be internal or external of the organization, and create a list of questions that should be answered by the check sheet process.
Creating Check Sheets • Step One • Identify the question • Develop and understand the question(s) that need to be answered before the data collection process • Step Two • Identify potential problem areas • Outline the production process • Figure out the potential processes that could be causing defects • Get employees involved who know the processes well
Creating Check Sheets • Step Three • Tracking problems/defects • Construct a tabular or schematic diagram in order to track problems in production processes • Step Four • Recording problems/defects • Physically record every instance that a problem/defect is encountered
Benefits • Efficiency/Speed • Systematic and Organized • Ease of use/Simplicity • Can be used in conjunction with other charts and diagrams for a more in depth analysis
Problems • Data Inaccuracies • Check Sheet Biases • Exclusion • Interaction • Perception • Operational • Nonresponse • Estimation
Real World Example • Mitsubishi Motors • http://www.mitsubishi-motors.co.jp/inter/NEWS/0010-03/n001020.html • Mitsubishi motors has defects in several car models and they use check sheets to track the defects in order to improve their production processes • The check sheet link is • http://www.mitsubishi-motors.co.jp/inter/NEWS/0010-03/n010215a.html
Check Sheet Exercise • Creating a Check Sheet • In groups of three to five people, choose a simple process, which can be internal or external of your organization, and create a check sheet that would seem most appropriate for the process you chose. • The design of the check sheet is to be determined by the group. • Refer to previous examples for ideas of how or where to begin if necessary. • Paper clip experiment
Summary • Check Sheets should be easy to use • Since data is gathered quickly, simplicity reduces margin for error. • As a rule of thumb, keep it simple • Only record relevant data • Use Check Sheets for quick analysis • Do not try to make general assumptions from data that is collected. In order for a more detailed analysis, data needs to be grouped by region, machine, process, etc. and should be used in conjunction with other quality tools.
