In a recent Accendo podcast, Chris Jackson and Fred Schenkelberg discussed who is responsible for producing a reliable product, which included designers and suppliers. I’m going to weigh in.
The reliability of any product depends on the reliability of the individual components and joints within the product. That is, the ability of the components and joints to withstand exposure to stressors without degrading to the point that they fail, resulting in the product no longer performing as required. Stressors, which include corrosion conditions, fatigue, and wear, were discussed in an earlier article.
Whether individual components and joints have the reliability required boils down to two basic aspects of engineering – selection and control. The appropriate form (i.e. shape, dimensions, features) and materials for components and joints must be selected during product design. Then, systems must be put in place to control fabrication of components and joints, ensuring their form and materials are as specified. This will enable the components and joints to consistently meet performance and reliability requirements.
So, who’s responsible for this selection and control?
