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]
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.
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.
If the inputs are indivisible and complementary, a small scale may be subject to idle times or to the underutilization of the productive capacity of some sub-processes. A higher production scale can make the different production capacities compatible. The reduction in machinery idle times is crucial in the case of a high cost of machinery. [10]
Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service. Lean manufacturing is particularly related to the operational model implemented in the post-war 1950s and 1960s by the Japanese automobile company Toyota called the Toyota Production System (TPS), known in the United ...
Data about the cost of production, including machine time, labor time and materials used, as well as final production numbers, is provided from the MRPII system to accounting and finance. [5] For the companies that want to integrate their other departments with their manufacturing management, ERP software are necessary.
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."
