Function cost analysis
Function Cost Analysis (FСА) (sometimes named "function value analysis" (FVA)) is the a method of technical and economic research of the
systemsfor purpose to optimize a parity between system's (as product or service) consumer functions or properties (also known as value) and expenses to achieve those functions or properties.
methodologyfor continuous perfection of production, industrial technologies, organizational structures was developed by Juryj Sobolev(Соболев, Юрий Михайлович) ( Russia) in 1948at the " Perm telephone factory" (Almost at the same time as L. D. Miles).
1948 Juryj Sobolev(Соболев, Юрий Михайлович) ( Russia) - the first success in application of a method analysis at the " Perm telephone factory" ( Perm, Russia).
1949- the first application for the inventionas result of use of the new method.
Today in economically developed countries practically each enterprise or the company use methodology of the kind of functional-cost analysis as a practice of the
quality management, most full satisfying to principles of standards of series ISO 9000.
* Interest of
consumernot in products itself, but the advantage which it will receive from its usage.
consumeraspires to reduce his expenses ( costor priceof functions).
* Functions needed by consumer can be executed in the various ways, and, hence, with various efficiency and expenses. Among possible alternatives of realization of functions exist such in which the parity of
qualityand the priceis the optimal for the consumer.
The goal of FCA is achievement of the highest consumer satisfaction of production at simultaneous decrease in all kinds of industrial expenses (production
costs). Classical FCA has three English synonyms - Value Engineering, Value Management, Value Analysis. It is not necessary to confuse method FСА as it takes place at some authors, to method Activity-based costing(ABC)
Technical system- the set of material elements (components) intended for satisfaction of any need of the person (society) or technical systemof higher hierarchical level, possessing even one property leaving for the sum of properties of elements (components) making it.
FCA object- subjected to the analysis of the HARDWARE or its elements.
subsystem- the systemwhich is a part analyzed HARDWARE.
supersystem- the system including analyzed HARDWARE.
Consumer property- abilityof the HARDWARE to satisfy any needof the person(or society) or other HARDWARE.
Expenses for maintenance and achieve consumer properties- the cumulativeresulted charges on technical systemat all stages of its life cycle.
cost analysis- definition of expenses for performance of functions and them
