Product Quality and Process Quality
Product quality
“Quality is the measure of excellence or state of being free from deficiency, defects, and significant variations", (Nader, 2009).
Quality of a product can be mainly assessed from a manufacturer and a customer point of view.
From a customer point of view, product quality is perspective as each individual perceives quality differently. Ultimately, product quality is the capability of the product to fulfil customer expectations as required from the users.
Quality from a manufacturer’s perspective depends on company size, culture, financial resources, human resources, market pressures and company strategy.
Due to the availability of a large number of products in the market, different industries have put forward different parameters that allow a product to be judged against the competition. For example, an electronic product may have quality parameters such as performance, reliability, safety and appearance that has to be met (UNIDO, 2006).
Process quality
Process quality targets the life cycle of a product from the beginning, design, development, roll out, updates and product support.
Both product and process quality are combined together and quality control measures put in place to ensure the final outcome is of a high quality.
Interaction between product quality and process quality
In order to produce a quality product it requires a quality process. This involves maintaining the process operating at a level that complies with required quality criteria. When the quality of a process varies it will have a direct impact on product characteristics and hence product quality. For example, a metal producing plant has processes such as cutting, machining, bending and coating. The smoothness, hardness and thickness etc of the metal are directly impacted by the quality of the processes. Once the metal is manufactured, the customer will judge it against the product
