Applying Yield Variance to a Practical Example

Example: Company ABC’s Toy Production

To better understand yield variance and its implications, let’s consider an example. Company ABC is a prominent toy manufacturer.

One of their popular products requires plastic parts in its production process. Each production run aims to achieve a standard output of 1000 finished toys.

The standard yield for plastic parts is 90%, meaning that the expected yield is 900 plastic parts for every 1000 toys produced. Unfavorable Yield Variance in Company ABC’s Production

During one production run, Company ABC faced an unfavorable yield variance.

Despite the expectation of producing 1000 toys, they only achieved an actual output of 950 toys. Upon analysis, it was discovered that the yield variance was caused by a lower than expected yield for the plastic parts, resulting in a shortage of 50 plastic units to complete the desired output.

Impact on Unit Cost and Profitability:

The unfavorable yield variance experienced by Company ABC directly affected their unit cost. The shortage of 50 plastic units increased the cost of each toy produced, leading to higher unit costs.

This impacted their profitability as they had to absorb the additional costs without achieving the desired output. Addressing Unfavorable Yield Variance:

To address the unfavorable yield variance, Company ABC must first investigate the cause of the lower yield for plastic parts.

They might find that it was due to issues such as machine malfunctions, inadequately trained operators, or variations in the quality of the plastic material. By identifying the root cause, they can implement corrective actions to minimize the variance and optimize their production process.

Importance of Continuous Improvement:

Company ABC’s experience highlights the importance of continuous improvement in the manufacturing process. By regularly monitoring their yield variance and analyzing the contributing factors, they can identify opportunities for enhancement.
