En choisissant soigneusement l'unité appropriée, les entreprises peuvent garantir la précision de leurs calculs, améliorer les processus de contrôle qualité et rationaliser les opérations de production. Comprendre les subtilités de l'unité de produit peut permettre aux entreprises de prendre des décisions éclairées et d'optimiser leurs performances globales.
Instructions: Choose the best answer for each question.
1. Which of the following is NOT a valid example of a unit of product?
a) A single screw
This is a valid example of a unit of product.
b) A pair of shoes
This is a valid example of a unit of product.
c) A kilometer of cable
This is a valid example of a unit of product.
d) A month of software subscription
This is the correct answer. While a software subscription is a product, the unit of product is likely a single user license or a specific feature, not a duration of time.
2. Why is defining the unit of product important for accurate costing?
a) It ensures that all costs are allocated equally to each unit.
This is not entirely accurate. Costs are allocated based on how they are related to the unit of product, but not necessarily equally.
b) It allows companies to compare costs across different products more easily.
This is a benefit of defining the unit of product but not the primary reason.
c) It helps to determine the cost per unit, which is essential for pricing and budgeting.
This is the correct answer. Defining the unit of product is essential for calculating the cost per unit.
d) It eliminates the need for complex cost accounting methods.
This is not true. Defining the unit of product does not eliminate the need for cost accounting methods.
3. What is the difference between the "unit of product" and the "unit of purchase"?
a) There is no difference; they always refer to the same unit.
This is incorrect. The units can be different.
b) The unit of product is always smaller than the unit of purchase.
This is not always true. The units can vary in size.
c) The unit of product is the unit in which the product is sold, while the unit of purchase is the unit in which the materials are bought.
This is the correct answer. The unit of purchase is how materials are bought, and the unit of product is what is actually sold to the customer.
d) The unit of product is determined by the customer, while the unit of purchase is determined by the supplier.
This is incorrect. Both units are determined by the company's internal processes and needs.
4. Which of the following industries is most likely to use "operation" as the unit of product?
a) Automobile manufacturing
This industry is more likely to use individual components or the complete car as a unit of product.
b) Software development
This industry might use features or lines of code as a unit of product, but not "operation."
c) Construction
This industry might use cubic meters of concrete or square meters of flooring as a unit of product, but not "operation."
d) Service industry (e.g., consulting)
This is the correct answer. Operations like a consulting session or a project phase are often used as units of product in the service industry.
5. What is the primary purpose of accurately identifying the unit of product?
a) To increase profit margins by minimizing production costs.
This is a possible outcome, but not the primary purpose.
b) To simplify production processes and eliminate unnecessary steps.
This is a possible outcome, but not the primary purpose.
c) To achieve precise cost calculations, effective defect tracking, and streamlined production processes.
This is the correct answer. Identifying the unit of product enables accurate cost estimations, better quality control, and improved production efficiency.
d) To satisfy customer expectations and ensure product quality.
This is a desirable outcome, but not the primary purpose of identifying the unit of product.
