Creating a Product Matrix

Creating a Product Process Matrix is a strategic exercise that assists businesses in aligning their manufacturing processes with the types of products they produce. This guarantees that each product is manufactured in the most effective manner possible, maximizing resources, lowering costs, and fulfilling market demand. Here’s a step-by-step strategy for developing an effective Product Process Matrix:

1. Identify Product Types

Start by categorizing your products based on key characteristics such as variety, complexity, and volume. Ask questions like:

• Is the product customized or standardized?
• Is it high or low volume?
• Does it require complex or simple assembly?

This helps to identify whether the product falls into categories like high variety/low volume or low variety/high volume.

2. Determine Suitable Production Processes

Based on the product characteristics, choose the appropriate production method. There are four main types of processes in the Product Process Matrix:

• Job Shop: Best for high variety, low volume products that are custom-made.
• Batch Production: Suitable for moderate variety and volume, where products are made in batches.
• Assembly Line: Ideal for standardized, high-volume production with low customization.
• Continuous Flow: Used for high-volume, standardized products, often in industries like chemicals or oil refining.

Each production method has specific strengths and weaknesses, so choosing the right one ensures operational efficiency.

3. Analyze Current Production Processes

Evaluate your current production procedures and determine how well they align with your products. Do you have a high-efficiency method for low-variety, high-volume products? Are things that require customization being manufactured in a standardized manner? This analysis helps find improvement opportunities, such as waste reduction or process optimization.

4. Map the Matrix

Create a visual representation of the Product Process Matrix. Place your product categories (based on type and volume) on one axis and the production processes on the other. Plot each product within the matrix to see where it fits best. This mapping will help you visualize which products align with which processes and identify any mismatches or opportunities for improvement.

5. Evaluate and Adjust

The Product Process Matrix should be a dynamic tool rather than a one-time activity. The matrix should be reviewed and adjusted regularly as products evolve and market demands shift. For example, a product that was initially manufactured in a job shop process could be converted to batch production as demand expands, or the assembly line could be streamlined as volume grows. To make sure your procedures continue to meet the demands of your products, keep improving them.

4 Stages of Product Process Matrix

The Product Process Matrix divides production strategies into four distinct stages, each suited to different product characteristics and manufacturing needs. These stages represent a progression from highly flexible, low-volume production to highly standardized, high-volume production. Understanding each stage helps businesses align their processes with product requirements to maximize efficiency and reduce costs.

1. Job Shop

Characteristics

Low volume, high variety, custom products.

Production Process

This stage involves the creation of highly customized products, with each item being unique or made-to-order. The manufacturing techniques are adaptable and versatile, allowing for a variety of product types. Machines and resources are set up for specific jobs, and products typically go through different stages in varied sequences.

Example

Custom furniture manufacturing, specialized equipment fabrication, or bespoke clothing.

2. Batch Production

Characteristics

Moderate volume, moderate variety.

Production Process

In batch production, products are made in groups or batches. This process is more efficient than job shop production but still offers some flexibility to cater to a variety of products. Batch production is typically used when demand for a product is steady but not high enough to justify continuous production.

Example

Food manufacturing, pharmaceuticals, or clothing lines with different designs or sizes produced in batches.

3. Assembly Line

Characteristics

High volume, low variety.

Production Process

The assembly line is designed for consistent, high-volume production. It is a series of activities in which each worker or machine completes a specified duty to gradually construct the product. This technology reduces both production time and cost, making it perfect for mass production. The manufacturing rate remains constant, and the product undergoes the same set of processes in a predetermined order.

Example

Automobile manufacturing, electronics production, or consumer goods like appliances and toys.

4. Continuous Flow

Characteristics

Very high volume, low variety.

Production Process

Continuous flow production is used for products that need to be manufactured in large quantities, often without interruption. The procedure runs all day and night, generating similar items. This technology is highly automated and intended to increase efficiency by minimizing downtime. It is best suited for sectors with high and consistent product demand.

Example

Oil refining, chemical manufacturing, or paper production.

Common Product Matrix Parameters

When creating a Product Process Matrix, numerous important factors are considered to guarantee that the manufacturing process is in line with the product type and market requirements. These parameters assist businesses in determining how well their products and manufacturing processes align and make production optimization decisions. The following are some of the most commonly utilized parameters in the Product Process Matrix:

1. Product Volume

Definition: The quantity of products produced over a certain period.

Impact: Higher product volumes typically favor more standardized and automated production methods (e.g., assembly lines or continuous flow). Low-volume products tend to be better suited for more flexible methods like job shops or batch production.

Impact: A highly flexible production system (such as a job shop) can handle a large range of product varieties, although it may be inefficient. Assembly lines and continuous flow systems are less adaptable, but more efficient and scalable for standardized products.

5. Setup Time

Definition: The time required to adjust or reconfigure machinery and production lines between different production runs.

Impact: Long setup times are common in job shop and batch production, where production lines are reset for each job or batch. Short setup times are crucial for assembly lines and continuous flow, where constant production of similar products reduces downtime.

6. Lead Time

Definition: The amount of time it takes from order to finished product delivery.

Impact: Due to more complex operations and changeovers, lead times in job shops and batch production are usually higher. Assembly lines and continuous flow systems, on the other hand, can shorten lead times by manufacturing standardized goods quickly and efficiently.

7. Production Cost

Definition: The total cost incurred during production, including labor, materials, and overhead.

Impact: Job shops tend to have higher production costs due to their customized, low-volume nature. Batch production can offer cost savings with economies of scale, and assembly lines or continuous flow production are often the most cost-efficient for high-volume, low-variety products.

8. Quality Control

Definition: The processes and standards in place to ensure product consistency and meet customer specifications.

Impact: Job shops often have more frequent checks and manual inspections due to the custom nature of products. In batch production and assembly lines, quality control is more standardized but may involve more automated checks. Continuous flow requires rigorous automated monitoring to maintain product consistency.

9. Automation Level

Definition: The extent to which machinery and technology are used to perform tasks without human intervention.

Impact: Job shops usually have minimal automation, with workers performing a variety of tasks. Batch production may involve some automation, especially for repetitive tasks, while assembly lines and continuous flow systems are typically highly automated to ensure efficiency and minimize errors.

10. Product Lifecycle

Definition: The stages a product goes through, from initial design to discontinuation.

Impact: Products in the early stages of their product lifecycle, when demand is low, are often better suited to flexible production methods like job shops. As the product moves through its life cycle and demand increases, it can transition to more efficient production methods, such as batch production, assembly lines, or continuous flow processes, to meet the high volume requirements.

2. Match the Production Process with the Product Type

Using the Product-Process Matrix, align your product with the correct stage of the production process:

• Job Shop: Best for highly customized, low-volume products. This process allows for flexibility but at a higher cost.
• Batch Production: Suitable for moderate volume and variety, offering some flexibility and cost savings. Ideal for products that don’t require high customization but must be produced in batches.
• Assembly Line: Perfect for high-volume, low-variety products, where efficiency is key. It’s most beneficial for products in their lifecycle’s growth or maturity stages.
• Continuous Flow: Used for very high-volume, standardized products. Best for commodities or well-established products with consistent demand.

3. Evaluate Efficiency vs. Flexibility

The Product-Process Matrix helps to strike a balance between efficiency and flexibility. Mass production methods, such as assembly lines, provide efficiency but lack flexibility. Job shops, on the other hand, offer more flexibility at a higher cost and longer production time. By understanding where your product lies on the matrix, you can optimize for either efficiency or flexibility based on the product’s needs and market position.

4. Optimize for Cost and Quality

The Product-Process Matrix guides businesses on balancing cost and quality control.

• Cost Control: For high-volume products, mass production methods like assembly lines or continuous flow will reduce production costs significantly due to economies of scale.
• Quality Control: For customized or niche products, job shops may need to maintain high-quality standards due to manual oversight in production.

5. Plan for Scalability

As your product grows, the production process will likely need to scale up. The Product-Process Matrix enables you to forecast how your manufacturing process will change. A product that begins in a job shop can gradually transition to batch production or an assembly line as demand grows, allowing for production scalability without sacrificing quality or customization.

6. Monitor and Adjust Over Time

Once your product strategy has been implemented using the Product-Process Matrix, keep track of performance, costs, and customer feedback. Prepare to alter the production method based on the matrix. If market demand changes or you need to tweak the features or variety of your product, the matrix will assist you in making intelligent decisions about re-aligning manufacturing processes to satisfy new demands.
