'COLA' is a manufacturer, retailer, and installer of a Split AC for industrial buyers. It started business in 2001 and its market segment has been low to medium level groups. The Company produces three types of ACs - COLA, FANTA and SPRITE grade. Until recently, its business model has been based on selling high volumes of a standard AC, brand name 'HEAT', with a very limited degree of customer choice, at low profit margins. 'COLA''s current control system is focused exclusively on the efficiency of its manufacturing process and it reports monthly on the following variances: material price, material usage and manufacturing labour efficiency. 'COLA' uses standard costing for its manufacturing operations. In 2018, 'COLA' employed 20 teams, each of which is required to install one of its 'HEAT' AC per day for 350 days a year. The average revenue per 'HEAT' AC installed is Rs 36,000. 'COLA' would like to maintain this side of its business at the current level. The 'HEAT' installation teams are paid a basic wage, which is supplemented by a bonus for every AC, they install over the yearly target of 350. The teams make their own arrangements for each installation and some teams work seven days a week, and up to 12 hours a day, to increase their earnings. 'COLA' usually receives one minor complaint each time a 'HEAT' AC is installed and a major complaint for 10% of the 'HEAT' AC installations.

In 2016, 'COLA' had launched the new AC, brand name 'HEAT-Cool'. This AC is aimed at high-level corporates and it offers a very large degree of choice for the customer and the use of the highest standards of materials, appliances, and installation. 'COLA' would like to grow this side of its business. A 'HEAT-Cool' AC retails for a minimum of Rs100,000 to a maximum of Rs 500,000. The retail price includes installation. In 2017 the average revenue for each 'HEAT-Cool' AC installed was Rs 300,000. Currently, 'COLA' has 7 teams of 'HEAT-Cool' AC installers and they can install up to 240 AC a year per team. These teams are paid salaries without a bonus element. 'COLA' has never received a complaint about a 'HEAT-Cool' AC installation. 'COLA''s business is generated from repeat orders, recommendations, and local press advertising. It employs three sales executives who earn an annual salary of Rs 300,000 each. It offers a six-month money back guarantee and this has to be fulfilled for 1% of its installations. 'COLA' has always been in profits but was shocked to see that in its results in 2017 it only earned 0.2% net profit on its turnover.

In 2018, the company wanted to improve its profitability however, the furnace operation was a bottle-neck in the process. The company is running at 100 % of capacity. The variable conversion cost is Rs100 per process hour. The fixed cost is Rs 4,800,000. The furnace operation is part of the total process for each of these three products. Thus, furnace hours are the part of process hours. In addition, the Cost Accountant was able to determine the following information about the three products:
