I. Introduction
Definition of cost accounting: the process of identifying, measuring, analyzing, and
communicating the cost information that is useful in the management of an organization.
Importance of cost accounting: it helps managers make informed decisions, control costs, and
evaluate performance.
Objectives of cost accounting: to determine the cost of products/services, to provide data for
pricing decisions, to monitor and control costs, to support budgeting and forecasting, and to
evaluate performance.
II. Cost Accounting Systems
Job order costing: a system used in industries that produce customized products or services,
where the cost of each job is separately determined.
Process costing: a system used in industries that produce large quantities of similar products,
where the cost of each process is determined and then divided by the number of units
produced.
Activity-based costing: a system that identifies the specific activities that create costs and
assigns them to products/services based on their consumption of these activities.
Target costing: a system that involves setting a target cost for a product/service and then
working backward to design and produce it at that cost.
Lean accounting: a system that provides financial information that supports implementing lean
principles and practices.
III. Cost Behavior Analysis
Variable costs: costs that change in proportion to the activity level, such as direct materials and
direct labor.
