With stiff competition and the demand for affordable products, manufacturing companies have to find means of
coming up with lower priced products. Sometimes in the quest to market a product at a lower price, manufacturers
tend to overlook into the quality aspects. There are several ways to lower the price of a product. One way is to use a lower grade or cheaper alternative material to manufacture the product. Sometimes this can decrease the lifespan of the product
or the reliability of the product. Manufacturers are supposed to do a proper feasibility study, conduct a proper trial run, field test, product reliability test etc whenever a different or cheaper material is used in manufacturing the product, if they skip any of these cycles or did not conduct a proper study, this is where we get a low quality product.
Another cost saving method by manufacturers is to shorten the cycletime or shorten the process time of the product, for example reduce the curing process of the product or reduce the inspection process. Sometimes when manufacturers tend to "overdo" these methods, this is when the quality of the product is compromised.
There are many other factors which affects the quality of product..cheaper packing material, mode of transportation, new workforce without proper skills,etc.. In order to maintain a product with optimum quality is not easy but with the right people and mindset and applying lean methodology, it is possible.
