Manufacturing workers are encouraged to engage in ongoing learning and development to enhance their skills, knowledge, and capabilities. This may involve participating in training programs, acquiring certifications, and staying updated on industry trends, best practices, and new technologies relevant to their roles.
Overall, manufacturing jobs play a vital role in producing goods efficiently, safely, and to high quality standards. Workers in manufacturing roles contribute to the success of their organizations by producing goods that meet customer requirements, driving operational excellence, and supporting the growth and competitiveness of the manufacturing sector.
How to Calculate Manufacturing Overhead:
Calculating manufacturing overhead involves determining the total indirect costs associated with producing goods in a manufacturing environment. Manufacturing overhead includes various expenses that are not directly attributable to specific units of production but are necessary for the overall manufacturing process. Here’s how to calculate manufacturing overhead:
1- Identify Overhead Costs:
Compile a list of all indirect costs incurred during the manufacturing process. These may include:
- Depreciation of factory equipment
- Rent and utilities for the manufacturing facility
- Factory insurance and property taxes
- Salaries and benefits for factory supervisors and support staff
- Maintenance and repairs of factory equipment
- Indirect materials used in production (e.g., lubricants, cleaning supplies)
- Other miscellaneous expenses related to manufacturing operations.
Determine Total Overhead Costs:
Add up all the indirect costs identified in step 1 to determine the total manufacturing overhead for a given period, such as a month or a year.
Calculate Allocation Base:
Select an appropriate allocation base to distribute manufacturing overhead costs across units of production. Common allocation bases include:
1- Direct labor hours: Allocate overhead based on the number of labor hours worked on production activities.
2- Machine hours: Allocate overhead based on the amount of time machines are used in production.
3- Direct labor cost: Allocate overhead as a percentage of total direct labor costs.
Determine Overhead Rate:
Divide the total manufacturing overhead costs by the chosen allocation base to calculate the predetermined overhead rate. The formula is:
Overhead Rate = Total Manufacturing Overhead Costs / Allocation Base
For example, if total overhead costs are $100,000 and the chosen allocation base is 10,000 direct labor hours, the overhead rate would be $10 per direct labor hour.
Apply Overhead to Production:
Once you have determined the overhead rate, you can apply it to each unit of production based on the actual amount of the chosen allocation base consumed by that unit. Multiply the overhead rate by the number of direct labor hours, machine hours, or direct labor cost associated with each unit to calculate the overhead cost allocated to that unit.
Record Overhead Costs:
Record the allocated manufacturing overhead costs as part of the total cost of production. These costs are typically included in inventory valuation and are eventually transferred to the cost of goods sold when the products are sold.
By accurately calculating manufacturing overhead, businesses can better understand the true cost of production and make informed decisions regarding pricing, profitability, and resource allocation.
What Occurs In Contract Manufacturing?
In contract manufacturing, a company (referred to as the “contract manufacturer”) is hired by another company (referred to as the “client” or “brand owner”) to produce goods on their behalf. This arrangement involves outsourcing the manufacturing process to a specialized third-party entity. Here’s what typically occurs in contract manufacturing:
Agreement and Negotiation:
The client and the contract manufacturer negotiate terms and conditions, including pricing, production volumes, quality standards, delivery schedules, and intellectual property rights. A contract or agreement is drafted to formalize the arrangement and protect the interests of both parties.
Product Design and Development:
The client provides specifications, designs, and other relevant information about the product to be manufactured. The contract manufacturer may offer input and assistance in refining the product design, optimizing manufacturability, and ensuring compatibility with production processes.
Sourcing of Materials and Components:
The contract manufacturer procures raw materials, components, and other necessary inputs required for production. This may involve sourcing materials locally or globally, depending on availability, cost, and quality considerations.
Production Planning and Setup:
The contract manufacturer plans and sets up the production process based on the client’s requirements. This includes configuring manufacturing equipment, establishing production lines, and implementing quality control measures to ensure consistency and compliance with specifications.
Manufacturing and Assembly:
The contract manufacturer produces the goods according to the agreed upon specifications and production schedules. This typically involves a range of manufacturing processes, such as machining, molding, assembly, and packaging, depending on the nature of the product.
Quality Assurance and Testing:
Throughout the manufacturing process, the contract manufacturer conducts quality assurance checks and testing to verify that the products meet the client’s specifications and quality standards. This may include dimensional checks, functional testing, and visual inspections to identify and rectify any defects or deviations from the agreed-upon requirements.
Packaging and Labeling:
Once the products are manufactured and tested, the contract manufacturer packages them according to the client’s specifications. This may involve labeling, branding, and preparing the products for distribution and sale in accordance with regulatory requirements and market preferences.
Logistics and Distribution:
The contract manufacturer coordinates logistics and shipping to deliver the finished products to the client’s designated location(s) or distribution centers. This may involve managing transportation, customs clearance, and inventory tracking to ensure timely and efficient delivery.
Post-Production Support:
Some contract manufacturers offer additional services such as after sales support, warranty management, and repair services to assist the client in addressing any issues or concerns that may arise after the products are delivered to market.
Overall, contract manufacturing provides companies with the flexibility to scale production, access specialized expertise and capabilities, reduce costs, and focus on core competencies while leveraging external resources to bring products to market efficiently and effectively.
