Telematics Data – Contour Plots and Multiple Parameter Analysis

Telematics Data – Contour Plots and Multiple Parameter Analysis

Introduction

The analysis of telematics data with two or more parameters is a complex process. The analysis of multiple parameters using contour plots is a powerful tool since a lot of information is captured in the graphics.

The best results come from a team effort. For engineering data, the team may consist of the design/development engineers, a programmer, and a reliability engineer or a statistician. The following is an analysis of engine speed, engine torque, and the transmission gear state to describe the process.

Understanding FMEA Severity Risk – Part 1

Understanding FMEA Severity Risk – Part 1

The Seriousness of Consequences

Have you ever been in an FMEA meeting where the team did not agree on the severity rating? Understanding and correctly applying severity risk is an important part of FMEA application. This article discusses the subject of severity risk, including examples for design and process FMEAs, and offers a tip on what to do when the team does not agree on the severity risk rating.

Training Effectiveness

Training Effectiveness

We need training that is useful.

All companies train their people. How can you get what you need? What is the most effective approach? Each section below contains a 2-minute video to expand on the topic provided.

We need the training impact to last longer than the class

A company sees a need for training. They set up a class agenda and bring in an instructor. The ratings were good, but no one is using the new information so no value was created. How can they achieve training success and make it stick? This video shows our approach to make it more beneficial and create company value.

FMEA Q and A – Difference Between Controls and Actions

FMEA Q and A – Difference Between Controls and Actions

FMEA Q and A

A reader is having difficulty seeing the difference between a detection control and a recommended action, and sees them as interchangeable. This has repercussions for the linkage between the Design FMEA and Design Verification Plan, and is the subject of this FMEA Q and A article.

Design of Experiments Process — A Decision Making Focus

Design of Experiments (DOE) is often only taught as a series of tools. Instead, we have used it as a tool in the Decision-Making Process which enhances implementation.

Each section below contains a 2-minute video to expand on the topic provided.

Where do we get started?

The setup and project definition are important for future success. Often, people want to jump to a solution. Then, they can start implementation and testing. Briefly pulling back to define the goal and appropriate outputs will help tremendously.

Understanding FMEA Recommended Actions – Part 1

Understanding FMEA Recommended Actions – Part 1

Actions Speak Louder than Words

Consider these questions: How many recommendations are needed to address the root cause of a high-risk problem? If the FMEA team is addressing an issue with high-severity and high-occurrence ratings, is it usual to have a single recommended action to reduce risk? Why not? Read on, to learn the essential elements of FMEA recommended actions, and answers to this questions.

FMEA Q and A – Auditing FMEAs

FMEA Q and A – Auditing FMEAs

FMEA Q and A

One of the more important topics in the FMEA body of knowledge is how to audit the effectiveness of FMEAs. Performing FMEAs properly and to a high quality standard is essential to obtaining the best possible results. This FMEA Q and A goes to the heart of FMEA effectiveness audits.

Understanding FMEA Controls – Part 2

Understanding FMEA Controls – Part 2

Problems and Solutions

In this article, we use problems and solutions to learn about FMEA controls. In the intermediate problem, we continue examining the door latch-pin failure of the DC-10 cargo door, as an example to identify FMEA controls. In the advanced problem, we analyze a fictitious FMEA relating to potential safety of someone trying to unjam a snowblower.
