Check Sheet: A Basic Quality Tool


Check Sheet is user friendly and simple format tailored for specific purpose relating to real time collection and recording of quality data. The data compiled in a Check Sheet is easy to use, understand and analyze without the help of any computer or programming aid. It easily can be simply done with pencil and paper. 


Where to Use:  

Process control and problem analysis are two main areas of application of check sheet e.g. production process distribution checks; defects and their cause. It is useful where the data can be observed and collected repeatedly.  The data can be qualitative or quantitative.


How to Use: 

Process Control: Key indicators of any process may be listed in the form of a check sheet and relevant information may be collected in these forms as below:

  1. Develop the Criterion: Specify operational STAGES of the event, ACTIVITY or PROBLEM which has to be observed.
  2. Data Collection Time: Specify WHEN the data of the event, activity or problem has to be collected and to what extent/how much.
  3. Create the Form: Create a TABULAR format for the data to be recorded.
  4. Verification of the Format: Collect TRIAL data by making check marks or cross (x) marks, straight lines or similar symbols. VERIFY that all the required data is collected in the form and nothing is missing/left out.
  5. Implementation: IMPLEMENT the format for use/collecting the data.  Initial TRAINING for the user is highly recommended.

EXAMPLE: Here is tabulation of material delivery delay data attributed to three reasons.

PROBLEMDelivery Delays (Days of the Week)TOTAL
Wrong Paperworkxxxxxxxxxxxx12
Courier Inefficiency xxxxxxxxxxxxxxx15
Cargo Flight Reschedulingxxxxxxxxxxxxxxxxxxxx20

Here the maximum delivery delays (i.e. 20 out of total 47) in the week are due to cargo flight rescheduling. This data can be used further for analysis to find the root cause by means of tabulating various factors such who, what, why, where and when etc. Repeatedly answering one or many of these relevant questions, the root cause can be found out.
