12.6 Quality control systems
The need to control and evaluate has led to a huge industry dealing with the issue of quality control systems for both manufacturing and service organisations. Organisations are concerned with being endorsed under various standards. Such endorsement identifies that an organisation has systems in place that support the objectives of quality. However, endorsement is only part of the equation. It is only when organisations pursue continuous improvement that real and sustainable benefits are achieved. The notion of continuous improvement is concerned with employees and people as well as with systems. It is concerned, if you like, with the human side of quality.
You are no doubt familiar with terms such as total quality management , quality service and quality assurance . Traditionally, quality control may have consisted of sampling to determine whether the completed product met design specifications. This can be dysfunctional as it can result in a particular person or section being blamed if something goes wrong.
Total quality management (TQM) has changed the traditional meaning of quality management. TQM is a strategic commitment to improving quality by combining statistical quality control methods with a cultural commitment to seeking incremental improvements that increase productivity and lower costs.
Quality is designed into the product and the production system. A defect is anything that dissatisfies the customer. Taking care of the rights and needs of the customer is the foundation of a quality system. In the maritime industry there is a growing preference for dealing with companies with quality assurance systems that can demonstrate a capability for consistently providing what is required, in a safe and responsible manner.
While the culture of quality has been widely adopted, for organisations operating in the international sector it is important to blend national and company cultures.
The strength of the argument for building quality into the design and process can be seen when the costs of poor quality are examined. For example these include complaint handling, fines and claims investigations, waste, scrap, re-work, negative publicity, losing a customer and the cost of finding a new customer.
In the transport sector Grewal (1997), noted lack of punctuality in pickup or delivery, high levels or returns or claims (for in-transit damage or breakages), poor communication, poor care of consignment, complex paperwork, nontransparancy of consignment, poor traceability of consignment, inadequately trained and motivated staff, etc. can all be identified as signs of poor quality.
An explanation of quality cannot be complete without consideration of safety. Safety is often seen as a cost impressed by regulation. A reminder of Bhopel and Exxon Valdez will serve to reinforce the point that accidents are expensive.
Quality control is a growing and vital part of the management process. Read:
