Function cost analysis (FСА) (sometimes called function value analysis (FVA)) is a method of technical and economic research of the systems for 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.
The purposes of the function model are: to describe the functions and processes, assist with discovery of information needs, help identify opportunities, and establish a basis for determining product and service costs. [17] A function model is created with a functional modelling perspective. A functional perspectives is one or more perspectives ...
The function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user. Function points are used to compute a functional size measurement (FSM) of software. The cost (in dollars or hours) of a single unit is calculated from past projects. [1]

[8] Management efficiency – Managers compare cost data from different time periods in order to see whether the cost centre is becoming more or less profitable.

Modern cost accounting originated during the Industrial Revolution when the complexities of running large scale businesses led to the development of systems for recording and tracking costs to help business owners and managers make decisions. Various ...
Business Process Modeling Notation Example. Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. [2] A common type of systems modeling is function modeling, with specific techniques such as the Functional Flow Block Diagram and IDEF0.
A Business Function Model (BFM) is a general description or category of operations performed routinely to carry out an organization's mission. They "provide a conceptual structure for the identification of general business functions". [27] It can show the critical business processes in the context of the business area functions. The processes ...
