Quality during Design

We’ve collected all sorts of preliminary information about our users that we’re using for a new product design. We may be faced with so much data we’re not sure where to turn first, or what design feature is a priority. There’s a simple, 2-way matrix we can use to help us sort it all out: an urgent/important matrix. We may have used it to prioritize tasks for ourselves or as a management strategy for our team. But, we can also use it to evaluate the tasks our users take when using our product. 

We talk more about this matrix in the podcast, and we talk through an example of how to use it to evaluate user tasks.

Visit the podcast blog for urgent/important matrix examples, including the example we stepped through.

When we’re looking at results (like measures of a characteristic), we need to take care not to get too hung-up on what the statistics is trying to tell us. Yes, statistical tools are a good way for us to make decisions and the results can act as proof for us. But, there’s a practical, engineering side to results, too. We need to evaluate the statistical significance along with the practical significance.

We review an example and how to document it.

In this episode we review sampling for design tests. We talk through a generic thought process for choosing a statistically relevant sample size and propose some basics that we can all learn about to better understand sampling.

Our goal is for us to be able to better talk through a sampling scenario with our quality and reliability engineering friends, and to better prepare for the information that they're going to want to know when asked, "How many do we need to test?"

It costs our customers to own our designed products. It costs them initially to purchase it, but it also costs them to use it, maintain it, repair it, and eventually dispose of it. And it costs our company in ways too, like processing, training requirements for customers, and warranty repair costs.

Life cycle costing can help our team choose between design alternatives, like alternate design options, features, manufacturing methods or suppliers. This type of analysis is a big topic in certain sectors of design like civil, transportation, construction, and capital equipment. But, we can use it for our smaller product designs, too, to compare our design choices - where it makes sense.

Visit the podcast blog at www.QualityDuringDesign.com for equations, an example life cycle cost analysis, and a recommended book.

Good reliability requirements are going to drive our design decisions relating to the concept, the components, the materials, and other stuff. So, the moment to start defining reliability requirements is early in the design process. But, what makes a well-defined reliability requirement? There are five aspects it should cover: do you know what they are? 

We'll describe what makes a good reliability requirement and examples of common (but not good) requirements.

We have good requirements for the reliability of our design. We also have a preliminary design with ideas of how we're going to manufacture it. Is our design idea good enough? Are there things we should do to improve its performance and reliability?

For a physical product, there are three general stages in its life cycle. In many cases the failure rates of physical products can be represented by a reliability bathtub curve. This curve is really a plot of a hazard rate function, also known as a failure rate function. We talk about data collection in the early design phase, what types of failures are typical for each phase, and design decisions we may make to improve our reliability, based on the failure rate function we plot for our system.

Flowcharting isn't just useful for manufacturing processes. We can use them in lots of ways to help us with design of products and to identify quality characteristics.  After all, products are used by people, and the way in which they use them is a process. 

• compare ideal vs. actual flowcharts 
• identify where there is disagreement about correct sequence or steps 
• identify common mistakes/problems at each step to mistake-proof the process and design
• analyze cycle time, look for holds or delays, find the critical path 

We also talk about specific flowchart analyses and how they can be used to analyze the User Process for Design. 

• Cost-of-Poor-Quality
• Critical-to-Quality
• Value-Added Analysis
• Deployment Flowchart

Visit the podcast blog for a graphic of common symbols of flowcharts.

Genichi Taguchi related his measure of quality (variation from the target spec) with economics, called the Taguchi Loss Function. It’s used to calculate the cost (in money) of a certain deviation from a target value. It assumes that the farther our quality characteristic is from our target value, the more costly it is to us.

We talk about how we can use the Taguchi Loss Functions as a way for us to set tolerances for our designs. Visit the podcast blog to get an interactive tool and the equations.

When we've identified a risk to our design or user process - and that risk can pose a potential harm - how many controls do we need to add?

We discuss prevention vs. detection controls, ALARP, as low as possible, and some scenarios where we could (and maybe couldn't) justify a risk as acceptable without adding additional controls.

How we describe and approach the issues we need to solve can affect how we react to them.  We know we’re supposed to be solving for root causes. But are we, instead, really just addressing symptoms? Are we celebrating the quick fix and then moving on without addressing the root of our issue?  

Recognize the common mishaps of us solving symptoms instead of really getting to the causes. And, clearly describe our problem in two parts (statement and description of facts) to be confident that we’re moving toward solving the causes.
