The billing rates based on the activity-based cost structure make more sense. These billing rates
reflect the ways the testing procedures consume the firm’s resources.
4. To stay competitive, Precision Laboratories needs to be more efficient in arctic testing.

occurs in setups and facility costs.
Perhaps the setup activity can be redesigned to achieve cost savings. Precision Laboratories
should also look for savings in the labor and supervision cost per test-hour and the total number
of test-hours used in arctic testing, as well as the utility cost per machine-hour and the total
number of machine hours used in arctic testing. This may require redesigning the test,
redesigning processes, and achieving efficiency and productivity improvements.
13-33 Life-cycle costing. Maximum Metal Recycling and Salvage receives the opportunity to
salvage scrap metal and other materials from an old industrial site. The current owners of the site
will sign over the site to Maximum at no cost. Maximum intends to extract scrap metal at the site
for 24 months and then will clean up the site, return the land to useable condition, and sell it to a
developer. Projected costs associated with the project follow:
