E-learning, or online learning, has made sharing niche knowledge resources such as GD&T entirely possible. But the key difference between e-learning today and years past is the increased technology allowing for greater student interaction and instant feedback on questions.

How important is student interaction for online learning? According to Jennifer Minotti, Ed.M., and Paul Giguere, Ed.D., online training gives access to colleagues and experts who might otherwise not be available, and places an emphasis on a learner-centered approach.

Some benefits of e-learning, such as self-paced study and standardization of learning materials, are universally known. But another factor you should consider is that learning GD&T online is a huge economic benefit, as there are no associated travel costs. If you or your team needs training, you can do it anytime, anywhere. ETI offers computer and web-based training for individuals and companies that need course materials in a corporate, LAN, multi- or single-user format.

Let’s explore two unique types of online training.

Computer-Based Training

E-learning globally connects students to high-level information easily and effectively. That’s why we worked so diligently to introduce our update to our own ’09 GD&T Trainer (see more below). This is perfect for larger companies that want to train many workers, in one or multiple locations.

Web-Based Training

This is a great training opportunity for individuals to take a class on their own, or for smaller companies that only want to train a few workers in any location. It’s virtually identical to enrolling in an online course at a traditional institution, such as a university. (Visit etilearn.com to find out more.)

Above all, one of e-learning’s greatest benefits is the opportunity of lifelong learning.

ETI’s GD&T Trainer is a computer-based training package that provides employees with interactive training, instant lesson feedback, and easily measured progress. The software was developed by GD&T expert Alex Krulikowski and is based on the ASME Y14.5-2009 Dimensioning and Tolerancing Standard.

“I have your GD&T training software and have not seen anything that beats it.”—Billy Garfield, Sr. Lead Designer, Comdev-USA

Wise people never wait until a problem darkens their doorstep to look for solutions. And you cannot possibly find solutions if you continually underestimate your problem. Hence, training IS the go-to solution. Training is considered a dirty word by some HR officials and managers because it’s seen as an unnecessary expense.

During a 5-year period, we’ve collected data from 1000s of clients throughout several major industries—automotive, aerospace and medical, to name a few—and discovered that there are companies bleeding as much as $10.5 million annually in liability and nonliability costs directly related to a lack of GD&T knowledge among workers.

These are the three ways not training can affect your bottom line.

1. Drawing Errors

A whopping 80% of engineering drawings contain errors, according to Alex Krulikowski, ETI’s founder. He spent nearly 30 years working directly with companies and has seen errors on 1000s of drawings. When a drawing is riddled with errors, it forces the manufacturing and quality folks to make uninformed decisions. This leaves the door open to costly mistakes later.

2. Non Liability Costs

When you create a bad part based on a flawed drawing, there will be problems by the time it gets to the inspection process, or distributed to suppliers. When a part has to be scrapped or reworked, there are associated costs with that, along with additional labor costs. There are instances where parts that should be retooled go on to the consumer market, which causes larger problems, such as recalls and lawsuits, down the road.

3. Liability Costs

These are the most expensive and unpredictable errors you could make. Some companies roll the dice on these, so to speak, because they need to push a product out and don’t consider outside factors that could really hurt the end product. But in some industries, such as automotive, you cannot afford to gamble on thinner profit margins. One really big lawsuit can result in company downsizing and a big loss in reputation.

Both non liability and liability costs typically range from $10,000 to $10,000,000 for each case. So every time you incur one of these costs, you’re footing a pricey bill. Whereas, you can spend a tiny fraction of those costs to have a better educated and confident workforce.

Which one makes more sense to you? Training, or not training?

Mar 04

Whether you or your team received GD&T training or are in pursuit of it, it’s important to manage your expectations and goals to effectively put those skills to work. After working with so many clients, we’ve learned that teams should put together a “training plan”—a simple outline of what it’ll take to help everyone get on the same page in order to reach GD&T proficiency. Below are the top 5 mistakes we’ve seen companies and team leaders make during and after the training process.

1. Not relating GD&T to the business goals

The point in educating your team in GD&T is to produce better results for your bottom line. But managers and team leaders often make these mistakes during the enrollment process:

  • Not knowing which training workers should receive. The content of each training is not relevant to every worker. Quality control specialists and CAD designers have different pains on the job—usually their experiences are not related.
  • Not weighing cost against outcome. We don’t just tout those 10-to-1 ROI stats for nothing. Spending $10,000 on training consistently will yield hundreds of thousands in results. You have to see the whole picture.
  • Not using training to address a specific problem. GD&T education is vital, but it works far better when you know where your issue lies. Is it during the inspection process? Are your manufacturing folks misinterpreting drawings? Seeing a rise in supplier disputes? Analyze your own data, then apply GD&T to counteract your weaknesses.

2. Lack of active management support

The general answer our instructors receive when students are asked, “Why are you here for training?” is: “My manager told me I needed to be here.” No other explanation given. Can’t expect students to feel engaged and focus when they don’t understand the value GD&T will add to their jobs. Managers and team leaders should be involved before, during and after the training. And, they are responsible for converting their team’s newfound skills into performance-based results.

3. Not training the whole organization

We debate this until we’re blue in the face sometimes, but we cannot stress enough that ALL drawing users in your organization need at least basic GD&T skills to reduce their error margin. No matter how skilled your workers are, they cannot read a drawing riddled with errors. On average, even the largest companies have trained fewer than 10% of their drawing users.

Also to truly achieve proficiency, your team needs more than 2 days of training. It’s a start, but it only equips them with the basics. Most workers receive only a week’s worth of GD&T training on average in college, and others none at all. Or for those who received training in the distant past, they need a refresher to recall the standards.

4. Not measuring results

If you spend money on training but don’t use it, you may as well throw it out the window. Once your folks are trained, you need to chart data to see where and how they’re applying their skills. Is there a reduction in drawing errors? How many dollars and cents is it saving the company? How is the training most effective?

5. Not using mentoring

Even for the most skilled workers, GD&T is not an easy topic to digest. Practice makes perfect definitely applies here. Students need reinforcement of their skills in order to gain the confidence to make the right calls on the job. If workers don’t feel comfortable applying the knowledge they’ve acquired, then the training will be less effective.

Keeping these tips in mind will help your team flourish after training.

Whether you’ve been in your job for a few years or a few decades, it’s common to fall prey to complacency. When you pretty much acquire a solid routine with your work, it’s easy to dismiss the importance of continuously learning new skills while reinforcing your current ones.

Reading how you can reduce drawing errors by 50% may seem irrelevant until you or your team makes a drawing mistake that could result in exorbitant warranty or litigation costs. It does happen. Quality Digest points out how simple drawing errors end up costing many companies millions of dollars over the years.

Engaging in GD&T training offers practical, on-the-job application that will enforce uniformity in your drawing specs and interpretation throughout the design, manufacturing and inspection processes.

Relevant to more than just early career engineers, this particular quote really stood out as being invaluable advice for all professionals:

“Seeking out professional development activities related to growing your soft skills will drive professional growth in dimensions you never knew existed,” Carl Vieth, Director of Corporate Education for University of Wisconsin-Madison’s Department of Engineering told ASME (American Society of Manufacturing Engineers) in a recent interview.

That advice obviously applies to more than just recent engineering grads.

Think of your path to GD&T proficiency as a pyramid progression: To attain a level of mastery in your skills, you first need to learn a few core competencies.


For those of you who’ve learned some GD&T concepts in the past, you may just need a refresher. Or if you have very limited experience using GD&T properly, you may need to relearn all of the basics.

Regardless of your knowledge, it’s good to get a solid grasp on these concepts so you can begin applying them consistently and accurately.

Training to consider at the Awareness level:

  • GD&T Overview
  • Engineering Drawing Requirements
  • GD&T for Manufacturing (manufacturing engineers and similar professionals)


If you’ve grasped the basic concepts of GD&T, you’ve accomplished the first steps on the road to proficiency. But fully understanding GD&T interpretation is an invaluable skill that not many designers and engineers possess. Some companies have noted that less than 10% of their staffs are GD&T proficient. This leaves a wide margin open to drawing misinterpretations, which can lead to supplier disputes over parts. Learning the ins and outs of interpreting GD&T properly will put you in that elite category of professionals who can confidently interpret GD&T on drawings.

Training to consider at the Interpretation level:


If you’ve reached the top of the pyramid (mastering awareness and interpretation levels), you’ve nearly crossed the finish line to reaching GD&T proficiency. But bear in mind: Applying the GD&T concepts you’ve learned is actually the hardest part of your journey. So it’s very important to get the training you need in this area to do it competently.

Training to consider at the Application/Analysis level:


We have a great feature on our website that allows you to assess your skills. Our GD&T Skills Assessment (based on ASME ’09 standard) and GD&T Skills Survey (based on the ’94 standard) will both help you determine where your skills need the most improvement.

When you or your team becomes bogged down with projects, time off the job can seem impossible at best. But wouldn’t you invest 2 days of your time if you knew undoubtedly that the knowledge you’d gain would change the way you work?

SEE: INFOGRAPHIC—If Your Team Were GD&T Proficient 

Let’s take a class of 14 engineering and quality folks from our 2009 GD&T Fundamentals ’94 workshop, for example. After attending this workshop for just 2 days, engineers rated the course at 93.182 while quality control specialists gave it 91.667. Their feedback helped us identify 3 key ways attending a GD&T workshop can make reaching personal and company goals highly attainable.

  1. It’s easy to do a self-assessment. If you are just guessing at what you’re doing, you’ll never have any idea where you truly stand. From the 14 workshop attendees mentioned above, the engineers saw a 60% increase in their GD&T knowledge while the quality control specialists reported a better than 50% increase. Why? Because workshop training forces you to dig deep and find where your weaknesses lie. It removes all the guesswork.
  2. It has a significant impact on job performance. All 14 attendees are required to use GD&T 40% of the time on the job. After putting in 2 solid days of training, their knowledge and accuracy had more than doubled—some ranked their improvement 80% or better. Training can serve as a refresher for skills you learned years ago but have since forgotten. Or bring you up to speed in areas where you received little to no training at all.
  3. The return on investment is as plain as day. Every company places the vast majority of its goals on its bottom line. A better equipped workforce reinforces this. An illustrated excerpt from our report shows how investing $18,200 in training for 14 employees can add up to nearly $200,000 in savings annually thereafter.

Great! Here are some resources to get you started.

In 1985, Alex Krulikowski began a small start-up company that provided training and consulting in a little-known discipline called geometric dimensioning and tolerancing. Twenty-eight years later, Effective Training Inc. has evolved into a thriving business that provides GD&T training, products, and services to organizations across the globe.

Alex’s first publication was a GD&T Self-Study Workbook in 1986. Since then, he has written numerous textbooks, workbooks, pocket guides, self-study courses, videos, computer-based GD&T courses, and reference guides. Topics range from GD&T fundamentals to advanced concepts,  tolerance stacks, ISO GPS, and more.

In 1986, a small group of students took GD&T courses in the newly formed ETI classroom on Wayne Road in Westland, Michigan. Today, the company provides onsite workshops to major corporations all over the world.

The training format has evolved as well.

In 2004,  Alex developed the first interactive computer-based training GD&T software, and ETI’s GD&T Trainer is now a valuable training option used by small companies and industry giants.  Many educational institutions utilize ETI’s digital instructor kits, and online and video courses provide more GD&T learning platforms.

In 2012, the company moved to its new Livonia, Michigan-based headquarters, where more than a dozen employees create, sell, and distribute GD&T products, while several ETI instructors travel the world teaching GD&T courses. Recent products include a textbook, pocket guide, workshops, and computer-based training based on the latest (ASME Y14.5-2009) standard.

ETI has also published an ISO Geometrical Tolerancing Guide based on various ISO GPS standards. Their newest product is the ISO GPS Quick Reference software.

In nearly three short decades, Effective Training has expanded from a one-man operation into a company that has become the largest provider of GD&T products in the world.
