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.
In manufacturing, it will involve production of high volumes of output. These approaches mean fixed costs are spread over a larger number of units of the product or service, resulting in a lower unit cost, i.e. the firm hopes to take advantage of economies of scale and experience curve effects. For industrial firms, mass production becomes both ...
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 ...
When some costs are sunk and some are not sunk, total fixed costs (TFC) equal sunk fixed costs (SFC) plus non-sunk fixed costs (NSFC) or TFC = SFC + NSFC. When some fixed costs are non-sunk, the shutdown rule must be modified. To illustrate the new rule it is necessary to define a new cost curve, the average non-sunk cost curve, or ANSC.
It is an alternative to cost accounting. The primary measures for a TOC view of finance and accounting are: throughput, operating expense and investment. Throughput is calculated from sales minus "totally variable cost", where totally variable cost is usually calculated as the cost of raw materials that go into creating the item sold.
If the external transaction costs are lower than the internal transaction costs the company will be downsized by outsourcing, for example. According to Ronald Coase's essay "The Nature of the Firm", people begin to organise their production in firms when the transaction cost of coordinating production through the market exchange, given ...
In microeconomics, diseconomies of scale are the cost disadvantages that economic actors accrue due to an increase in organizational size or in output, resulting in production of goods and services at increased per-unit costs. The concept of diseconomies of scale is the opposite of economies of scale.
