Quality Management Tools
Quality Management tools help organization collect and analyze data for employees to easily understand and interpret information. Quality Management models require extensive planning and collecting relevant information about end-users. Customer feedbacks and expectations need to be carefully monitored and evaluated to deliver superior quality products.
Quality Management tools help employees identify the common problems which are occurring repeatedly and also their root causes. Quality Management tools play a crucial role in improving the quality of products and services. With the help of Quality Management tools employees can easily collect the data as well as organize the collected data which would further help in analyzing the same and eventually come to concrete solutions for better quality products.
Quality Management tools make the data easy to understand and enable employees to identify processes to rectify defects and find solutions to specific problems.
Following are the quality management tools:
Check List – Check lists are useful in collecting data and information easily .Check list also helps employees to identify problems which prevent an organization to deliver quality products which would meet and exceed customer expectations. Check lists are nothing but a long list of identified problems which need to be addressed. Once you find a solution to a particular problem, tick it immediately. Employees refer to check list to understand whether the changes incorporated in the system have brought permanent improvement in the organization or not?
Pareto Chart – The credit for Pareto Chart goes to Italian Economist – Wilfredo Pareto. Pareto Chart helps employees to identify the problems, prioritize them and also determine their frequency in the system. Pareto Chart often represented by both bars and a line graph identifies the most common causes of problems and the most frequently occurring defects. Pareto Chart records the reasons which lead to maximum customer complaints and eventually enables employees to formulate relevant strategies to rectify the most common defects.
The Cause and Effect Diagram – Also referred to as “Fishbone Chart” (because of its shape which resembles the side view of a fish skeleton)and Ishikawa diagrams after its creator Kaoru Ishikawa, Cause and Effect Diagram records causes of a particular and specific problem .The cause and effect diagram plays a crucial role in identifying the root cause of a particular problem and also potential factors which give rise to a common problem at the workplace.
Histogram – Histogram, introduced by Karl Pearson is nothing but a graphical representation showing intensity of a particular problem. Histogram helps identify the cause of problems in the system by the shape as well as width of the distribution.
Scatter Diagram – Scatter Diagram is a quality management tool which helps to analyze relationship between two variables. In a scatter chart, data is represented as points, where each point denotes a value on the horizontal axis and vertical axis.
Scatter Diagram shows many points which show a relation between two variables.
Graphs – Graphs are the simplest and most commonly used quality management tools. Graphs help to identify whether processes and systems are as per the expected level or not and if not also record the level of deviation from the standard specifications.
