What Makes a Top Shop Pop?

Looking at the Top Shops survey, an individual might wonder what it is that makes a machine shop profitable. To explain how we determine the key drivers of revenue and profit in machine shops, our Chief Data Officer Steve Kline is hosting a webinar to explain it in detail, but we can cover the broad strokes here.

Collecting Data on Manufacturing

Since 2012, more than 3,000 shops have responded to the Top Shops survey, providing us with a deep well of data. In addition to gathering numerical data, such as capacity utilization, lead time and profit margin, the survey gathers data on what machine tools, HR programs and improvement methodologies that see use in the shop. With that raw data, we get to work making sense of it.

We take every piece of numerical data and use a statistical analysis to correlate it with gross revenue per machine, gross revenue per part, and profit margin. To do this, we divide the data into the top and bottom quartiles – data groupings representing a quarter of the results – and look at the correlation of those quartiles with every piece of numerical data. And, we look at the percent of shops in the top and bottom quartiles of gross revenue and profit data to understand the correlation between the technologies, shop practices, and HR programs used with the revenue and profit data. With these data points all correlated, we can look at how technology and management tools relate to earnings and profit across all shops.

Analyzing Data to Identify Impact

Once we correlate the data, we come to an important question: What is relevant? To figure this out, we use a comparative analysis to look at how different technologies and practices impact the success of a shop. 

There are two factors our analysts look for when it comes to determining the relevance of a process, the correlation and the significance. Correlation is easy to understand: Is the presence of a process or technology likely to coincide with increased profits? Obviously, this is a meaningful indicator of value added. However, it is equally important to look at the significance of a technology.

By comparing the top and bottom quartiles, we can see what technology is driving financial improvements

Steve Kline Jr. Top Shops

Steve Kline Jr. – Chief Data Officer for Gardner Intelligence – speaks at the 2019 Top Shops conference. According to Kline, the data from Top Shops can help us identify which technologies provide a significant impact on the profits of a machine shop.

According to Kline, significance can be measured by looking at the degree of correlation. For example, if we wanted to look at how machine type compares to gross sales per machine (GSM), we would look at the top quartile of GSM – the 25% of shops who average the largest dollar amount in sales per machine. We would then look at what percentage of those shops use each machine type, then compare that percent of shops in the bottom quartile – the 25% of shops with the lowest sales per machine – that use the same machine type.

Using this comparison method, we can say how much more likely shops that perform well in a given metric are to use a given technology. If the magnitude of the difference between use in the top and bottom quartiles is 20% or greater, then we consider it significant, meaning that the use of that technology likely drives improved financial performance.
