9: Validation

9: Validation

Article by Mike Freier

In the last blog post, we discussed how incorporating Agile principles can improve your hardware product development process. Not only will you be able to accelerate your schedule, but you can also develop higher quality products with lower costs and reduced risks. Furthermore, Agile frameworks and techniques can fit into your existing new product introduction (NPI) and stage gate process, so your high-level standard operating procedures do not have to change.  

Once you have engineering and beta units in hand, validation and verification can begin. In this stage, engineering teams should test your product against the engineering design specification to verify that your product meets the performance, reliability, regulatory, manufacturing test, and safety goals.

Estimate Reliability Functions Without Life Data

Estimate Reliability Functions Without Life Data

ASQC Reliability Review, Vol. 13, March 1993

This paper shows how to estimate field reliability functions from ships and returns. It offers to estimate field reliability functions from your data. It suggests how you can use these estimates to improve service and inventory management. [Links to Google Sheet and user guide follow the paper.]

You can estimate field reliability functions without life data. You don’t need to know each part’s time to failure. In fact, if you don’t know times to failures, you have to estimate field reliability functions from ships and returns, unless you have a sample of times to failures, and some of the sample failed.

What is Design of Experiments?

What is Design of Experiments?

If you work in manufacturing, quality, or engineering, you’ve probably heard the term “Design of Experiments,” or DOE. Maybe you’ve even helped collect data for one without fully understanding what was going on behind the scenes. That’s okay. DOE is a sophisticated statistical method, but even if you’re not the one crunching the numbers, understanding the big ideas behind it can make you a more effective technician, engineer, or manager.

At its core, Design of Experiments is a structured statistical approach to testing. It helps us understand how different inputs (or factors) affect an outcome (or response). Whether you’re adjusting a process to improve tensile strength, dialing in machine settings to reduce defects, or figuring out which supplier provides the most consistent material, DOE helps answer one big question: What settings or conditions will give me the result I want?

Quality Objective 5: TEAM

Many ideas grow better when they are transplanted into another mind than the one where they sprang up.  Oliver Wendell Holmes

In this article, I will outline how to evaluate an FMEA against the FMEA Quality Objective for FMEA Team. I’ll include relevant information from the chapter in the FMEA Preparation series called “Assembling the Correct FMEA Team.”

Kolmgorov-Smirnov Two-Sample Test for Censored Data

Kolmgorov-Smirnov Two-Sample Test for Censored Data

Submitted to ASQC Reliability Review, Nov. 1996

A client wanted to compare the Kaplan-Meier (nonparametric maximum likelihood) estimators of the reliabilities of the old and new products. That is, he wanted me to test reliability functions, Ho: R1(t)=R2(t) for all nonnegative t vs. Ha: R1(t)≠R2(t) for some nonnegative t.

Because I’m lazy and fixed in my ways and because I thought it would be easier to explain, I chose the Kolmgorov-Smirnov (K-S) test [Gnendenko]. It’s convenient, practically every statistics text has the tables, and I can program tables and the test statistic easily. The test uses the maximum absolute difference between the Kaplan-Meier estimates of the two reliability functions. Reject Ho if maximum absolute difference, Dmn=max|R1(t)-R2(t)| exceeds a critical value, where m and n are the two sample sizes.

6: Design & Planning – Part 3: Design for Excellence (DfX)

6: Design & Planning – Part 3: Design for Excellence (DfX)

by Mike Freier

Design for Excellence (DfX) is a holistic approach to designing a hardware product that takes into account how the product is made at scale. In addition to understanding your manufacturing plan and target costs, there are six categories to consider: assembly, cost, manufacturing, test, service, and supply chain.
