activity-based costing requires four steps. list the four steps in the order they are performed.

Activity based costing have four steps, the steps are as follows:
1. Identification and classification of all the activities in the value chain in relation to the production of the product.
2. Estimation of total cost for each of the activities identified.
3. Computation of a cost driver rate for each activity based on a cost allocation base which has a causal link to the cost of the activity.
4. Application of the activity cost to product using the appropriate cost driver rate.

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
