Spark Architects, a Calgary-based architecture firm, designs and constructs buildings. It prices each job on a cost plus 25% basis. Overhead costs in 2020 are $9,900,000. Spark's simple costing system allocates overhead costs to its jobs based on number of jobs. There were three jobs in 2020. One customer, Eeny, (each job is named after the customer) has complained that the cost and price of its building in Edmonton was not competitive.

Recently, Spark's controller, Megan Moe, has initiated a detailed review of the overhead allocation to determine if overhead costs should be charged to jobs in proportion to consumption of overhead resources by jobs. She gathers the following information:

Quantity of Cost Drivers
