1. Lean manufacturing is characterized by all but one of the following:
a. Employee empowerment
b. Total quality management
c. Inventories of goods awaiting further processing or consumption
d. Elimination of waste
2. Lean manufacturing uses value streams to produce a family of products that require the same manufacturing sequence. Value-stream costing is an approach often used to determine the unit product costs in a lean manufacturing environment. Which of the following best describes how unit costs are calculated using value-stream costing?
a. Value stream costs divided by units shipped
b. Value stream costs divided by units produced
c. (Total prime costs + overhead costs assigned to the value stream using a plantwide rate) divided by units produced
d. Activity-based costing assignments within the value stream
3. A manufacturing cell within a value stream is structured with four processes and associated processing times (for one unit):
Molding: 6 minutes
Grinding: 5 minutes
Polishing: 5 minutes
Finishing: 4 minutes
How many units can the cell produce per hour (on a continuous running basis)?
a. 3 units per hour
b. 12 units per hour
c. 15 units per hour
d. 10 units per hour
4. Total productive efficiency is achieved when both technical efficiency and allocative efficiency are achieved. For a given mix of inputs that produce a given output, which of the following is consistent with improving technical efficiency (using the given input-output mix as the benchmark)?
a. More output is produced using more inputs.
b. More output is produced with the same inputs.
c. More inputs are used to produce the same output.
d. The least costly technically efficient input combination is chosen.
