Every decision in the product development process affects cost: design is typically considered to account for 70–80% of the final cost of a project such as an engineering project [1] or the construction of a building. [2] In the public sector, cost reduction programs can be used where income is reduced or to reduce debt levels. [3]
Target costing is defined as "a disciplined process for determining and achieving a full-stream cost at which a proposed product with specified functionality, performance, and quality must be produced in order to generate the desired profitability at the product’s anticipated selling price over a specified period of time in the future."
Kaizen costing is a cost reduction system used a product's design has been completed and it is in production. [1] Business professor Yasuhiro Monden [2] defines kaizen costing as . The maintenance of present cost levels for products currently being manufactured via systematic efforts to achieve the desired cost level. [citation needed]
Process costing is an accounting methodology that traces and accumulates direct costs, and allocates indirect costs of a manufacturing process. Costs are assigned to products, usually in a large batch, which might include an entire month's production. Eventually, costs have to be allocated to individual units of product.
Overall costs of capital projects are known to be subject to economies of scale. A crude estimate is that if the capital cost for a given sized piece of equipment is known, changing the size will change the capital cost by the 0.6 power of the capacity ratio (the point six to the power rule). [16] [d]
Design-to-Cost (DTC), as part of cost management techniques, describes a systematic approach to controlling the costs of product development and manufacturing.The basic idea is that costs are designed "into the product", even from the earliest concept decisions on and are difficult to remove later.
An important part of standard cost accounting is a variance analysis, which breaks down the variation between actual cost and standard costs into various components (volume variation, material cost variation, labor cost variation, etc.) so managers can understand why costs were different from what was planned and take appropriate action to ...
The Williamson tradeoff model is a theoretical model in the economics of industrial organization which emphasizes the tradeoff associated with horizontal mergers between gains resulting from lower costs of production and the losses associated with higher prices due to greater degree of monopoly power.
