Companies use SPC Software to prevent errors from occurring as well as use historical data to determine where you need to improve processes.

Why Do We Need Statistics Anyway? Capable and Stable Processes

Why statistics? Because they are possibly the most useful tool we have to understand what might happen. Statistics make it possible for us to make fairly accurate predictions with small groups of data. It is not possible to predict individual events but statistics will give insight to the overall results. But let’s dig deeper on why do […]

What’s the value of piece of mind? Cost vs. Value.

A Story: Cost vs. Value

A friend of mine was helping his son move out of the house and across the country this past weekend. As most 20 year olds do, his son “had it all figured out” and had “taken care of all the details”. “Don’t worry about it Dad, I’m an adult and can take care of myself,” he said.  

 

At one point in the move, my friend needed to move the U-Haul his son had rented for the move. After tossing him the keys, his son said, “Be real careful with it Dad. I didn’t buy the insurance.” My friend asked why he didn’t buy the insurance. The response was fairly predictable, coming from a 20 something who thinks he’s going to live forever: “I didn’t want to the spend $14 to insure the vehicle. I figured if I’m just really careful, I won’t have to pay the money for the insurance and everything will be ok.”

My friend’s response was also predictable, coming from man with 55+ years of experience in the randomness and unpredictability of life: “I see. So you just figured $14 was too much to pay to protect the vehicle and that you’d rather just pay the whole $45,000 to replace the vehicle if something goes wrong, right?”

The Lesson

There are several lessons here. The first has to do with the wisdom that comes with age and the hubris of youth. To wit, Mark Twain once said:

“When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21, I was astonished at how much the old man had learned in seven years.”

But another deeper lesson is here as well, and it has to do with cost vs. value. Too often, people look at the cost of doing something vs. doing nothing as a cost that doesn’t need to be incurred because it’s not something they’re currently spending money on.

Those of us who have the benefit of wisdom that comes with age know that while cost is something to be considered, the value is often more important. Any fool can look at the cost of paying $14 for insurance vs. not paying for the insurance and see that in the present, it’s better to spend $0 than to spend $14.

A wise person looks to the future though and sees what that $14 is buying: insurance. Protection. Piece of mind.

What this means to us

In the manufacturing world, a certain degree of variation always exists. This is why we do what we do. We give companies of all sizes and in all industries the tools to know, in real-time, the where, what, when, why, and how much when it comes to variance. We help you figure out what could be improved with your processes to reduce your costs and ultimately your risk.  The essence of SPC is probability—bringing a greater degree of certainty to an uncertain world.

Is there a cost to these tools? Yes, although it’s probably less than you would think. Are these tools valuable? 5,000 companies think so. So there’s only one question that really matters when we’re talking about cost vs. value:

A Look in the Mirror: Robust SPC Software

Robustness

Along with our users, we tout the benefits of SPC software.  We wrote the book on the core concepts of variation and how to observe it in real-time.  The idea of anticipating variation in products and processes, known as robustness, exists as an additional path to minimizing variation.  But that got us to thinking.  How have we as a software company – that helps others measure and act on variation  – developed a robust software ourselves?

Using SPC Software Data As a Tool for Process Improvement

,

In today’s corporate environment, information means the difference between profitability and losing business. In manufacturing industries, concerns about reducing scrap, reducing rework, increasing user productivity, and gaining knowledge about your production history is a top priority. Is there a truly useful yet simple tool for process improvement?

Where does this data come from? From your quality data. Your Statistical Process Control (SPC) software data is your warehouse of information related to how to monitor your production company-wide, to ensure your processes are operating optimally, to increase the productivity of your personnel, to manage the lifecycle of your machines, and to leverage your existing equipment to produce new products.
