As the chief engineer of a small fabrication shop, Christine Ford refers to herself as a "jack-of-all-trades." When an order for a new product comes in, Christine must do the following: 1. Design the product to meet customer requirements. 2. Prepare a bill of materials (a list of materials required to produce the product). 3. Prepare an operations list (a sequential list of the steps involved in manufacturing the product). Each time the foundry manufactures a batch of the product, Christine must perform these activities: 1. Schedule the job. 2. Supervise the setup of machines that will work on the job. 3. Inspect the first unit produced to verify that it meets specifications. Christine supervises the production employees who perform the actual work on individual units of product. She is also responsible for employee training, ensuring that production facilities are in proper operating condition, and attending professional meetings. Christine's estimates (in percent) of time spent on each of these activities last year are as follows: Designing product 12% Preparing bills of materials 7% Preparing operations lists 10% Scheduling jobs 16% Supervising setups 8% Inspecting first units 6% Supervising production 22% Training employees 13% Maintaining facility 4% Attending professional meetings 2% 100%
