Achieving Innovation

Achieving Innovation

We want to be more innovative – but how?

Many companies talk about their desire for Innovation. Can Design of Experiments (DOE) help in that process? Each section below contains a 2-minute video to expand on the topic provided.

Too often, we manage on hope

How often do we hear a design or process development team express optimism – “We are almost there!” And how long does that same response continue without progress? The key is to decide when we have tried long enough using informal methods. Predictability and confidence are important to achieve project success.

Underused Product Development Tools

Underused Product Development Tools

Is that tool really going to help me?

We do not want tools that waste our time. How do we know which tool can create benefit for us? Here are a few tools worth using on most projects. Each section below contains a 2-minute video to expand on the topic provided.

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.

Achieving a Robust Design

Achieving a Robust Design

This time we are going to create a robust design

Every project begins wanting to impress the customer, complete on time and perform smoothly. However, this tends to erode away quickly and the optimization objectives are saved for the next project or next phase.

But you can achieve it now!

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.

Prototypes and Learning

Prototypes and Learning

Prototypes Help You Learn About Your Product

To reduce schedules, prototype cycles are often randomly slashed. Eventually the time and resources are needed and create cost and schedule over runs. We need to recognize that prototypes exist to help us learn about our product. If we use a risk based test strategy approach, we can test at lower levels to gain the required understanding. Then, we can confirm our learning with the higher level, system prototypes.

Just 4 minutes and 19 second long. To me, a prototype does include bench testing at lower levels as long as it includes the relevant functionality to represent the area for learning. [Read more…]

Model Building

Model Building

Statistical Model Building

Model Building is a key theme for several advanced techniques. It boils down to creating an equation. Done well, one can predict and forecast how things will behave. Creating understanding reduces product risk and increases the chances for success.

Just 3 minutes and 9 second long, lets get the basics of model building to improve your understanding of how a system works. [Read more…]

ANOVA Calculation Example

ANOVA Calculation Example

An Explanation and an ANOVA Calculation Example

Our white paper regarding t-test calculations has been very popular. Those that use the t-test tool regularly have commented “I finally understand what it is all about.”

The natural question they ask me next is “have you done anything with the F-test?” It is another common tool and one that is equally misunderstood.

Due to popular request, here is our attempt at explaining the F-test tool, in the two possible methods of use. [Read more…]

The Basis of Design of Experiments is Comparison

The Basis of Design of Experiments is Comparison

A t-test Example

The basis of DOE analysis is comparing two samples. This methodology can be used just as well for changing one variable or more than one variable as in DOEs. Comparison of means is as simple as the t-test.

Some people initially feel intimidated considering the connection of DOE with statistics. Once they understand it in simple terms, the topic comes together for them.

So let’s see if we can accomplish that for you now.  [Read more…]

Practical Application of DOE

Practical Application of DOE

Get Started with DOE with This Practical Introduction and Overview

A tool is only as useful as knowing when and how to use it. In this webinar we will discuss how to identify an appropriate DOE project, and how to set up (define) a DOE. A process for DOE execution will be provided and discussed. We will also provide the thought processes needed to know when a DOE application is present. [Read more…]

What is Robust Design?

What is Robust Design?

The concept of robust design is commonly discussed, but what exactly is it? What options are available for achieving robust design? How do you know if it could be appropriate for your new product or process application?

This overview helps answer those questions – contact Perrys Solutions for more specific assistance. [Read more…]

Knowledge Based Decisions

Knowledge Based Decisions

Using Data for Knowledge Based Decisions

There is much talk about data based decision making, but I think that misses the point. We make decisions based on knowledge. Data needs to be translated into that knowledge, and yet not all knowledge can be measured. This has been my training philosophy for a number of years now and has been quite effective. [Read more…]
