In Act 1, Scene 1 of Shakespeare’s tragedy King Lear, Lear asks his three daughters to proclaim their affection for him which the first two, Goneril and Regan, do with genuine warmth, but the third, Cordelia, does not. She rather coldly says that she loves her Majesty according only to her bond, no more nor less. He’s taken somewhat aback by her callous comment and responds by saying “How, how Cordelia! Mend your speech a little, lest it mar your fortunes.”
Shakespearean actors worth their salt know full well that it’s not only the meaning of the words they speak but the way they speak them that makes what they say worth listening to. They are keenly aware of how to use articulation, modulation, tempo, sound and pronunciation to affect their speech. They are elocutionists who, to paraphrase one dictionary’s definition, are masters in the art of speaking effectively in public.
Here are three key steps to improving—or mending—your speech so you, too, can speak more effectively. Once you’ve read them and practiced the suggested exercises, you’ll be well on your way to becoming a more polished speaker and, who knows, even a proficient enough master to go on stage and play Goneril, Regan, Cordelia or Lear.
First: Variety above all else. You never want your voice to sound colorless, dull, passive or lifeless, so to give it character and make it interesting to listen to, change speeds, expand its range and play with dynamics. Which would you rather see, a river placidly and monotonously rolling along without anything in it to grab and hold your interest or one that’s alive with activities that catch your eye and make you want to stop and pay attention? The same with the voice and variety.
Also, pause, pause and pause yet again. You never want to run phrases together so that you prevent audiences from understanding, appreciating or enjoying what you’re saying. Silence is, indeed, golden so, to quote the great American raconteur Will Rogers, “never miss a good chance to shut up.” Actors and storytellers vary their voices and use silence to keep their audiences engaged and involved. Listen to your favorite actor or actress reciting a poem or reading a novel and you’ll hear what I mean. You’ll certainly be taken in by how they use their voices and pauses to hold your interest. Better yet, record yourself reading, say, A. E. Houseman’s short poem “When I was one and twenty” from “A Shropshire Lad” and listen to what you sound like when you play it back. Did you vary speed, range and dynamics and use pauses to make the poem come alive and be worth listening to, or did you merely go through the motions and read it without vocal inflection or pausing so it came across as boring, bland and, in a word, blah. Hopefully, the former.
When I was one-and-twenty
I heard a wise man say,
‘Give crowns and pounds and guineas
But not your heart away;
Give pearls away and rubies
But keep you fancy free.’
But I was one-and-twenty,
No use to talk to me.
When I was one-and-twenty
I heard him say again,
‘The heart out of the bosom
Was never given in vain;
‘Tis paid with sighs a plenty
And sold for endless rue.’
And I am two-and-twenty,
And oh, ‘tis true, ‘tis true.
You’ll find that, as you practice varying your voice and pausing, you, too, will turn into an actor or storyteller who’s more than adept at using variety and silence to persuade, influence, motivate, entertain or educate the people you’re talking to. So, vary away and shush.
Second: Enunciate, enunciate, enunciate. English is a hard, percussive language and, to speak it well, consonants need to be sharp and incisive. Many speakers of English, both native and foreign, don’t do this enough and, as a result, listeners all too often fail to understand what’s being said because speakers don’t pronounce their “b”s, “t”s, “v”s, “l”s, “m”s, “p”s or “d”s clearly, cleanly and consistently. So ask yourself which consonants you don’t articulate well and work on them. Try the following tongue twisters and see if they’ll help. As you go through them, notice how many consonants you miss—quite a few, I’ll wager.
Try them again making sure to enunciate the next consonant as emphatically as the one before and you’ll notice a marked improvement.
So, enunciate sharply and consistently and you’ll be better off for it.
Third: Handle with care. For your voice to be the expressive, compelling, engaging and appealing instrument you want it to be, it needs more than its fair share of TLC.
It is extremely fragile, though paradoxically quite strong, and can become damaged much more easily than people think it can without proper care. So, to speak well:
Also, avoid as much as possible:
To paraphrase W. H. Auden, “all (you) have is a voice,” so the more you take care of it and use it wisely, the more it will be able to do what you ask it to.
The British actress Dame Penelope Keith once said that when she went to school everyone had elocution lessons, not to sound posh but so they could be understood. Understanding, of course, is at the heart of any communication so it goes without saying that the more effectively and expertly you use variety, silence and diction to speak and the more you take care of what the composer Richard Strauss calls “the most beautiful instrument in the world (and the most difficult to play)”, the greater the impact of what you say will have on those listening to you. In short, just remember that what you say will only be as good as how you say it.

Lead engineers are incredibly overworked and their time is disproportionately valuable compared to some more junior engineers. But when it comes to doing project cost estimations, we don't have much of a choice but to ask some of these high-value engineers for the estimates if we want a realistic level of accuracy. Plus, the unfortunate reality is that many project costs end up being too high to justify the screening business case, so the project is canceled, and the high-value engineering time is wasted. I found a unique solution to this time sink using RSM to create a Ballpark Project Cost Estimator.
Not only did the ballpark estimator reduce engineering time spent on early phase projects, it also shortened the market opportunity evaluation timeline. This enabled a level of market opportunity screening that the organization had never experienced before. It ended up being an incredibly useful business tool that I wish more organizations had the benefit of using. I am excited to share the 5 steps to creating your own Ballpark Project Cost Estimator.
Figure 1. Project cost driver factor level definitions example. This is the recommended level of structure around each factor scoring level.
Figure 2. Historical Data Design for the sample project. We’re using 3 discrete levels for numerical factors to analyze the structured survey data.
In a real application, I found that I only had enough projects to build a linear model of the predicted expense for a given score of the twelve tri-level ordinal factors. In the sample, since I'm using fewer factors I have enough data for a higher-level model so I'm going to use it just because I can! Tip: when entering the design data, right click in the top left area of the data table and add a comments column. Or, select View > Display Columns > Comments. Put the project name in that column so that we can view it later on during the analysis phase.
In some real applications, there were some areas of the modeled space which had almost no data. But that is actually not a problem at all if we think critically about it. Since future projects will most likely look like projects that have been done in the past, there should be few projects that are in areas of the design space that don't have any data. Figure 2 shows one area of the model that illogically would cost less than zero dollars. This area has no actual data and illustrates this point.
Being aware of this limitation is why we implemented some of the process steps in step 5 around our understanding of the limitations of this tool. Figure 2 also shows the power of the crosshairs window view. It is showing that in the current area, the ballpark project cost is ~$6.5M, with a 95% CI Low of $3.5M and 95% CI High of $9.4M. That's a fairly wide range, but it's good enough to start a conversation about whether the project is worth investing in.
Figure 3. RSM screenshot of the sample data with cross-hairs window open from View > Show Crosshairs Window
As a result, anytime someone used the model, it would spit out a projected value and a list of the projects that were the closest in terms of similar "product of product" scores. To use Design-Expert's built-in capability here, go to Display Options > Design Points > Show and the actual points you measured will show up on the interactive plots. This will also show the project name that you previously added to the comments column in the design data entry.
With some very structured definitions of project cost driver characterization and Design-Expert software we were able to nearly eliminate the time that high-value engineers spent on early-stage project cost estimations. This enabled our product planning, strategy, and budgeting offices to speed up their early stage planning while reducing the load on our overtaxed engineers. We also built some process around the limitations of the tool to ensure that the organization wouldn't end up in a situation without clear lines of accountability. This is a great example of the many ways that DOE, RSM, and statistical methods can streamline business planning.

A recent discussion with a client led to these questions—“How do we keep design of experiments (DOE) training “alive” so that long-term benefits can be seen? How do we ensure our employees will apply their new-found skills to positively impact the business?” In my 20+ years as a DOE consultant and trainer, I have seen many companies who invested in on-site training, only to have it die a quick death mere days after the instructor leaves. On the other hand, we have long-term relationships with clients who have fully integrated design of experiments into the very culture of their research and development, and wouldn’t consider doing it any other way. What are the keys that lead the latter to success?
Key #1: Top-Down Management Support
Management must focus on long-term results versus short-term fixes. Design of experiments is a key tool to gain a fundamental understanding of processes. When combined with basic scientific and engineering knowledge, it helps technical professionals discover the critical interactions that drive the process. It’s not free, experimentation costs time and money. But forward-thinking companies understand that the long-term gains are worth the short-term expense. Management needs to buy-in to the use of DOE as a strategic initiative for future success.
Key #2: Data-Driven Decisions
Long-term success is achieved when management insists on using data to make decisions. My first engineering role was in a company that told us “All decisions are made based on data.” Engineers were expected to collect data and bring it to the table. DOE was one of the preferred methods to collect and analyze data to make those decisions. Key #2 is ingraining the expectation into the business that data-driven results will benefit the company longer than gut-feel decisions.
Key #3: Peer-to-Peer Learning
People like to learn from each other. Training can be sustained by learning from DOE’s done by peers. One way to support this is to plan monthly “lunch and learn” sessions. Everyone brings their own lunch (or order pizza!) and have 2-3 people do informal presentations of either an experiment recently completed, or their proposed plan for a future experiment. If the experiment is completed, review the data analysis, lessons learned, and future plans. If it is a proposed DOE plan, discuss potential barriers and roadblocks, and then brainstorm options for solving them. The entire session should be run in an open and educational atmosphere, with the focus on learning from each other. This key demonstrates the practical application of DOE and inherently encourages others to try it.
Key #4: Practice, Practice, Practice
Company management should plan that the output of on-site training is a specific project to apply DOE. Teams should plan an experiment that can be run as soon as possible to reinforce the concepts learned. As DOE’s are completed, the data can be shared with classmates simply to provide everyone with some practice datasets. The mantra “use it or lose it” is very true with data analysis skills and setting aside some time to get together and review company data will go a long way towards reinforcing the skills recently learned. Schedule a follow-up webinar with the instructor if more guidance is needed.
Key #5: Local Champions
There are always a couple of people who gravitate naturally towards data analysis. These people just seem to “get it”. Invest in those people by providing them with additional training so that they can become in-house mentors for others. This builds their professional reputation and creates a positive, driving force within the company for sustainability.
The investment in on-site training should include a company plan to sustain the education long-term. Good management support is an essential start, establishing expectations on using design of experiments and other statistical tools. Employees should then be connected with champions, followed by opportunities to apply DOE’s and share practical learning experiences with their peers.
