Which of the following refers to the process of eliminating errors during data processing?
Quality Glossary Definition: Mistake proofing Show
Also called: poka-yoke, fail-safing Mistake proofing, or its Japanese equivalent poka-yoke (pronounced PO-ka yo-KAY), is the use of any automatic device or method that either makes it impossible for an error to occur or makes the error immediately obvious once it has occurred. It is a common process analysis tool. When to Use Mistake Proofing
Mistake Proofing Procedure
Setting and Regulatory FunctionsSetting functions are the methods by which a process parameter or product attribute is inspected for errors:
Regulatory functions are signals that alert the workers that an error has occurred:
Mistake Proofing ExampleThe Parisian Experience restaurant wished to ensure high service quality through mistake proofing. They reviewed the deployment chart (a detailed flowchart that shows who performs each step) of the seating process shown below and identified human errors on the part of restaurant staff or customers that could cause service problems. Mistake Proofing: Restaurant’s deployment chart The first potential error occurs when customers enter. The maitre d’ might not notice a customer is waiting if the maitre d’ is escorting other customers to their table, checking on table status, or conferring with kitchen staff. The mistake proofing device is an electronic sensor on the entrance door. The sensor sends a signal to a vibrating pager on the maitre d’s belt to ensure that the maitre d’ always knows when someone enters or leaves the restaurant. Other mistake proofing methods replaced the process steps requiring the maitre d’ to leave the front door to seat customers. A possible error on the customers’ part was identified at the step when diners are called from the lounge when their table is ready. They might miss the call if the lounge is noisy, if they are engrossed in conversation, or if they are hard of hearing. The mistake proofing chosen by the team was to replace the step of the process in which the maitre d’ called the customer’s name over the loudspeaker. Instead, during the greeting step, the maitre d’ notes a unique visual identifier of one or more members of the party. When the table is ready, the table busser notifies the waiter, who comes to the maitre d’ and learns how to identify the customers. The waiter finds the customers in the lounge, escorts them to their table, gives them menus, and takes additional drink orders. Not only does this mistake proofing method eliminate a customer-caused problem, it improves the restaurant ambiance by eliminating the annoying loudspeaker, keeps the maitre d’ at the front door to greet customers, creates a sense of exceptional service when the waiter “magically” knows the customers, and eliminates additional waiting time at the hand-off between maitre d’ and waiter.

What is the process of testing and eliminating errors in a program?Definition: Debugging is the process of detecting and removing of existing and potential errors (also called as 'bugs') in a software code that can cause it to behave unexpectedly or crash. To prevent incorrect operation of a software or system, debugging is used to find and resolve bugs or defects.
What type of error is a violation of the rules of a programming language?A syntax error is a violation of the rules of the programming language.
Which of the following steps describes the last step that should be done in the development of a computer program?Create the documentation
The final step in the process is to create the documents that you need to describe the program.
Which of the following is a structured programming technique that graphically represent the detailed steps required to solve a problem?Explanation: Flowchart is a structured programming technique that graphically represents the detailed steps required to solve a program. Usually, it shows the steps as boxes of different types, and these boxes are connected with arrows.
