what are the reasons of variation in product

No two products are ever exactly the same, which means that they’ll always have some variation. Variation is a natural part of the product development process, and it’s something that you need to embrace if you want to make your products as successful as possible.

Reasons for Variation in Product

There are many reasons for variation in product. Some of the reasons include: manufacturing variations; design variations; seasonal variations; and supplier variations. Manufacturing variations can be due to differences in the production process, which can lead to variations in the quality of the product. Design variations can be caused by changes in the design of the product or by changes in the manufacturing process. Seasonal variations can be due to different demand patterns during different times of the year. Supplier variations can be due to differences in ingredients, production methods, or packaging.

Solutions to Eliminate Variation in Product

Variation in product is a common issue. There are many reasons for variation, but here are four main causes:

1. Inadequate or incorrect manufacturing processes: Poorly executed manufacturing processes can lead to a high level of variation in products. This is due to the fact that different parts of the manufacturing process can produce different results. Incorrect materials selection or inadequate design can also lead to variation.

2. Unstable raw materials: Raw materials can be unstable and unpredictable, which can result in a high level of variation in products. This is because the quality and composition of these materials can change over time, leading to differences in product quality.

3. Poor supplier management: Suppliers must be managed well if products are to be produced consistently and with low variation levels. Poor supplier management can lead to erratic quality levels and product variability. Suppliers who are not meeting agreed-upon standards or who are not following through on commitments can cause major issues for manufacturers.

4. Human error: Mistakes made by employees during the manufacturing process can lead to a high level of variation in products. This is because employees can make errors that affect the final product quality.


There are many reasons why variation in a product can happen. Some of these reasons could include manufacturing inconsistencies, environmental factors (such as temperature or humidity), or even the individual’s biochemistry. However, the most common reason for variation is due to human error. When products are produced by humans, there is always the potential for mistakes to be made which can result in different batches of product arriving at different times and with different aspects being slightly off.
