Tolerance allocation is usually considered only at the stages when designers are designing the product and manufacturing/process engineers are forming a process flow for manufacturing the product. In this paper, serious thought is given to formulating the tolerances for a product considering the most crucial stages of manufacturing, quality, use, and reuse stages of a product life cycle. A framework with an example of alternatives with attributes – cost, performance, and sustainability is discussed to achieve the intended tolerance allocation by considering multiple stages of the life cycle using the Hypothetical Equivalents and Inequivalents Method (HEIM). Extending this framework to products like mobile phones, laptops, watches, etc. would help to avoid the redesigning of the product in the future for making it efficient in terms of cost, performance, and sustainability. Also, using this concept products can be reused with liberalized tolerances to obtain the same performance as new ones leading to cost savings and improving the sustainability of the product.
