HALT! Watch out for that weakest link

HALT (Highly Accelerated Life Test) uses the weakest link mentality. We apply stresses beyond what our designs would normally see in the environment to make something fail. It’s meant to be an iterative test program where you are testing, analyzing the results, determining the root cause, fixing the design, and then testing it, again.

Listen-in to the podcast or read the transcript to find out more about its roots, why you should perform HALT (or not), when in the design process it’s best (hint: really early), and who likely needs to be involved.

The Designer’s Risk Analysis affects Business, Projects, and Suppliers

It takes a village to produce a design from concept to realization. Everyone along the way seems to think of risk a little bit differently. Designers are both directly and indirectly involved with all these risk management methods, but it’s important to understand who is looking at what type of information. Why? Because of communication. One group might think that risk management is covered in the way they’re thinking it should be, when in actuality it’s not.

This podcast will review risk management of other functional groups and how a designer’s risk affects them.

• Business/Marketing risk management
• Project Manager risk management
• Supplier Management

As a designer you have an important job and a unique perspective to analyze risk of your design and a responsibility to communicate it so everyone can help reduce risks.

A big failure and too many causes? Try this analysis.

We have identified a failure of our design. It’s a complicated failure that has multiple potential root causes, and some that are conditional. Is there a tool that can capture it all and help us prioritize our reactions to get rid of this problem? Yes, there is: Fault Tree Analysis!

Learn what it is and how it can help us get a handle on that big failure:

• all of our causes are mapped out in a visual diagram
• we can identify cut sets
• we can see where to prioritize resources where its best to eliminate or reduce causes

Why Your Design Inputs Need to Include Quality & Reliability

You’re nearing the end of your project, getting cross-functional approval on your design, when your QE or RE friend comes running with a big, red STOP button! Let’s avoid that!

Quality and Reliability are INPUTS into the design process, much earlier than by the time we have a prototype in-hand (even at the black-box, input-output phase). Getting the QEs and REs involved early will help your design be a success with suppliers, manufacturers, and your cross-functional team.

My product works. Why don’t they want it?

Have you ever designed a product that works but that customers just don’t want to use?

We’ve put a product to market only to find that the users just don’t want to use it. They’re buying it, so there’s perceived value in it. It’s functional, it does what we say it will do, it really works! But they’re not repeat buyers and not making good recommendations to others (it’s sort of making the company look bad).

What went wrong? In some cases, there’s warning signs to watch for during your design development. And, if looking to the design process for an answer, there’s some tools and strategies to help prevent that from happening before product launch, or to help as a starting point when you plan for your version 2.0.

This podcast will review the strategies and pitfalls and how to avoid them. [Read more…]

QDD 001 How to Choose the Right Improvement Model

You have a design you want to make better. Or you’re working within a designing framework that you think needs to be updated. Quality folks use and promote some standard problem solving and continuous improvement methods, and you’ll want to get started with the right one, or reference the right acronym when getting buy-in for your project.

You may have heard of PDCA, PDSA, and DMAIC. You vaguely know these represent improvement processes, but don’t really know what their differences are. When should you use which one, and for what? [Read more…]
