Cost of poor quality (COPQ) or poor quality costs (PQC) or cost of nonquality, are costs that would disappear if systems, processes, and products were perfect. COPQ was popularized by IBM quality expert H. James Harrington in his 1987 book Poor-Quality Cost. [1] COPQ is a refinement of the concept of quality costs.
In process improvement efforts, quality costs tite or cost of quality (sometimes abbreviated CoQ or COQ [1]) is a means to quantify the total cost of quality-related efforts and deficiencies. It was first described by Armand V. Feigenbaum in a 1956 Harvard Business Review article.
Cost Estimating is an approximation of the cost of all resources needed to complete activities. Cost budgeting aggregating the estimated costs of resources, work packages and activities to establish a cost baseline. Cost Control – factors that create cost fluctuation and variance can be influenced and controlled using various cost management ...
The concept has been widely employed as a metaphor in business, dating back to at least 2001. [5] It is widely used in the technology and pharmaceutical industries. [2] [3] It became a mantra and badge of honor within startup culture and particularly within the technology industry and in the United States' Silicon Valley, where it is a common part of corporate culture.
Quality, cost, delivery (QCD), sometimes expanded to quality, cost, delivery, morale, safety (QCDMS), [1] is a management approach originally developed by the British automotive industry. [2] QCD assess different components of the production process and provides feedback in the form of facts and figures that help managers make logical decisions.
The cost driver is a factor that creates or drives the cost of the activity. For example, the cost of the activity of bank tellers can be ascribed to each product by measuring how long each product's transactions (cost driver) take at the counter and then by measuring the number of each type of transaction.
Total variable cost (TVC) is the same as variable costs. [5] Fixed cost (TFC) are the costs of the fixed assets those that do not vary with production. [6] Total fixed cost (TFC) Average cost (AC) are total costs divided by output. AC = TFC/q + TVC/q Average fixed cost (AFC) is equal to total fixed cost divided by output i.e. AFC = TFC/q. The ...
Failure analysis is the process of collecting and analyzing data to determine the cause of a failure, often with the goal of determining corrective actions or liability. According to Bloch and Geitner, ”machinery failures reveal a reaction chain of cause and effect… usually a deficiency commonly referred to as the symptom…”. [ 1 ]
