Education options have exploded.
For the past 75 years, we read books, gone back to campus, attended workshops, traveled to conferences, and participated in evening meetings. Today we have more options from more sources for our professional development.
You have signed up to sit for the CRE exam.
You have the education and experience. Then you look at the CRE body of knowledge. The breath of statistics, the range of tools, the plethora of concepts.
You need to review the material. Where do you start?
You may already know my position on MTBF.
If not, in short, do not use MTBF at all, ever, in any form. So what should we use instead?
I suggest using reliability, the probability of success over a specific duration.
Let’s discuss what will work for you.
Early and often during product development, the team needs to know the expected reliability performance of the current design. The values provide information to make decisions.
We have the ability to create meaningful estimates. Or, not.
Selecting as a supplier for components or subsystems involves many aspects including the desired reliability performance.
Once selected the ability of the supplier to provide items that meet or exceed the reliability requirements relies on their understanding of the requirements and operational conditions related to the specific item within the system.
It also relies on the supplier’s knowledge of their own design and manufacturing processes as it related to the reliability performance.
A common request of reliability professionals is to design a set of reliability tests.
Many rely on various standards such as 85°C / 85%RH, to determine if a system is reliable, yet the standards do not provide a means to translate the results to your specific situation.
When components fall outside specs the chance for quality and reliability issue increases.
Let’s explore a couple of design and manufacturing cases where effectively using statistical process control will enhance your product’s reliability performance.
A tolerance specification is how we communicate the allowance for part variation.
Variation happens, and when it is within what we expect, great. Otherwise, quality and reliability issues ensue. Let’s explore how to set tolerances to improve reliability properly.
Let’s understand the process data, stability, and design constraints in an attempt to find a balance to create meaningful tolerances.

We work on projects to improve reliability.
There may not be the field data immediately available. Let’s explore how you can improve the overall program while delivering on your project.
Specifically, what’s with cost and procurement?

Mastering the statistical tools related to reliability engineering allows you to master reliability.
Identifying, characterizing, understanding, predicting, and improving reliability all require statistics. Let’s discuss how it works and what will work for you.

Every project and program includes reliability engineering.
This may be obvious with a structured program and reliability plan or may be unspoken. The product or system will have some level of reliability performance whether or not anyone is overtly working to achieve a reliability goal.

There are many reasons to use accelerated testing and just as many ways to conduct the testing.
Matching and balancing cost, risk, and results takes some skill.
Let’s talk about the key elements to consider so you select the best approach for your test.

We often want to know if our product will work as expected in our customer’s environment.
Creating an environmental test plan that clearly shows weaknesses and strengths should be part of your program for each product.
Let’s explore the steps and resources you should consider when creating an environmental test plan for each product.
We will discuss why using standards or even the plan from the last program may not provide you meaningful information.
Understanding how your product responds to your customer’s environment provides the information for your team to make improvements and improve product reliability.
