The live test

It can take a lot of time to get your presentation slide just right. However, once you got to that point, it should be super quick to recreate it. You can call this a ‘live test’. Take pen/paper, or open SlideMagic, and create the chart on the fly while someone is watching and listening. “We have 3 options, each has distinct pros and cons, I think number 2 is the best one”. If you are struggling to do this quickly and in a logical flow, your chart is probably too complex to be understood by a live audience. This is similar to a school teacher using the blackboard in the proper way.

Information hierarchy

I just returned from a short trip to Paris to show my son around some of the famous sites and restaurants. In 2021, that means a lot of health checks and tests. I was probably the only one in the airline terminal that looked at all the forms with the eye of a typographer.

I am not talking about elegance here, pure functionality. The people at check in desks are looking for “positive” or “negative”, the date the test was given, and whether the passport numbers match. On the test result form, the thing that is printed biggest is the name of the testing laboratory…

All this can be fixed easily with an adjustment of font sizes.

What you really want to say

Very often, after you created that data chart that you thought drives the point home, you change the headline with an even more powerful statement. In those cases, consider changing the entire data chart…

---Severe COVID-19 patients, ages 12-60 in ISRAEL---

Only 19% of the population are unvaccinated and are responsible for 78% of the severely hospitalized.

Only 2 patients under the age of 20 so without them it is only 15% who are not vaccinated. pic.twitter.com/NX4EQ2uIjg

The above can also be show this way:

Demo versus manual

Giving a demo of your application or web site to an investor or potential partner is different from teaching a new user how to use it by herself.

For the user:

• Where do all the buttons sit

• How to log in

• How to update settings

• Where to find your account details

• How to create a project from scratch

• Etc.

For the investor / partner:

• What does the app do?

• Show me a walk through of a “story” or use case

• Have a project ready to show

• Look, there is actually a piece of software that is working…

• Etc.

In presentations, you are most likely to deal with scenario 2. Do all the prep work (logging in etc.), and design a very clear script of what you want to show, cutting out any tangents and other delays. Keep it short and focused. Rehearse your walk through, and as a backup, have a series of consecutive screenshots ready just in case Murphy’s law kicks in.

Rounding numbers in data charts

How to round numbers in a data chart? It depends. The chart below does not look very appealing

The numbers are hard to read. This chart can serve 2 purposes. Either show the trend in sales, or show the exact sales figures. To show a trend in sales, simply show the accounts in thousands, and round up to one decimal point:

If you need to provide the actual precise sales data (for accounting or tax purposes), put it in an appendix slide that does not even pretend to show a trend:

Overstoryfying

Some article titles are click bait, others seem genuinely interesting and I am curious to find out the answer to the question posed. The disappointment is big when the journalist embarks on a very long story where characters are introduced and developed, background stories presented until the punch line comes somewhere halfway the 10 minute article.

A good product or company pitch does not have to be long.

Streaming a presentation

Music streaming services such as Spotify change the way musicians make music. With an unlimited amount of songs to listen to, users can now skip through tracks quickly. The result: musicians put the ‘hook’ or chorus of the song really early in the track to convince new listeners to stick around just a few seconds longer. During a live performance of the same song, the build up could be different.

The same applies to your slide decks that you send for someone to read without you being there to explain. The investor or customer is ‘streaming your slides’. Think about how to put that ‘hook’ in your story to keep the viewer interested.

Hooks don’t have to be blunt. A massive drum solo as your song opening might get people to hit the skip button. “We will have $3bn sales in 18 months” sounds impressive but might not be credible. An unusual chord change, or a counterintuitive perspective on the market could do the trick.

Visual math

Following my post from last week about pi, here is a link to a page full of beautiful visualisations of mathematical concepts. Often, a written formula is not the right way to explain math and proportions….

Plugged in

This blog post by Fred Wilson resonated with me.

Surrounding yourself with smart people is not enough to make (investment) decisions. Now that I am knee deep into coding applications myself, I finally start to understand technologies that I have been pitching in dozens of slide decks over the past decades.

I think it goes a bit further than Fred’s blog post. Really smart people (not saying I am) with MBAs (I have one), that work at prestigious companies such as McKinsey (I worked there) are extremely good at telling you why something will not work, and 99% of the time their arguments make perfect sense. It is very hard for these people though to commit to believing in something that will work. Advisors are not entrepreneurs.

Winging it

“Winging” a presentation, making it up on the spot, is extremely hard, and I would say, impossible. All people that seem to get up on stage and deliver a perfect pitch without any effort have in fact been rehearsing this over and over and over. (The previous instances where they pulled off the same trick). You need to practice really hard to be spontaneous.

When you look at a piece of paper with the scribbles of your thoughts, it seems like you have it all in your head. Everything is there. But standing in front of an audience is different. Your eyes are moving quickly across the piece of paper, going back and forth if relationships are not clear. With speaking, there is no rewind option. You need to build that “visual” in people’s minds step by step.

Many things can go wrong here:

• You forgot the exact sequence of your points and you realize it too late, now you are stuck without a way to go back

• You get distracted and are not sure where to pick things up, as you try to get your thoughts together, you repeat a few things you already said

• You delivered that powerful punch line too early and now your speech ends with a mumbling “well, that’s it, thank you”

Don’t wing your pitch.

The right proportions in design

Certain layouts and compositions look right, others seem wrong. We can see it, but we can’t point our finger to exactly why.

This formula for the constant pi got my attention:

From John Wallis, 1656 pic.twitter.com/VXqTWGeLkO

— Fermat's Library (@fermatslibrary) August 28, 2021

It is the so called Wallis product, a beautifully simple representation of a number that seems very random, the first 50 digits of pi are 3.14159265358979323846264338327950288419716939937510..…

Pi governs the shapes of rounded shapes, , waves and much more. The elegance of a circle is simple. But it is governed by a complex set of harmonics and ratios that all relate to each other. Beautiful designs have them, beautiful music has them. In most cases, we only appreciate the end result without grasping the underlying logic.

Presentation Zen on YouTube

Garr Reynolds was the first presentation blogger in the world back in the mid 2000s. His book “Presentation Zen” is still the standard introduction into the world of presentation design. His blog has gone quiet over the past years, but recently Garr has been active on YouTube covering among other things how to improve your Zoom presentations. Garr might no longer be in your RSS reader, but it is worth adding him to your YouTube subscriptions.

Scaling of data charts in SlideMagic

In SlideMagic, you do not have to worry about picking the right scale for your data chart. The entire chart adjusts itself to the numbers you type in. See the example below:

To make sure that a consistent scale is used for your entire chart, you need to place all your data points in one shape, instead of using multiple shapes for example for each month.

P.S. I have added this monthly sales comparison chart to the SlideMagic slide library so you can easily use it in your own presentations as well. Search in the app for ‘sales’ and it will pop up.

How to punctuate bullet points

Dr Clare Lynch is “chief business writing expert” at Doris and Bertie Ltd and a University of Cambridge writing instructor, she has an excellent YouTube channel that deserves more viewers.

In a recent video, she explains the official rules for punctuating bullet points, full stops or not, capitals, etc.

She gives 3 options and a warning:

Colon: no capitals, no full stops

The long hand version with capitals, and full stops

For writing: semi colons

Don’t mix sentence styles

Back at McKinsey in the 1990s, we were taught to write paragraphs in bullet point form but starting with what we called a “clunk”, with a heavy paragraph sign as the bullet point anchor (a pilcrow), and leave the full stop out after the last sentence (but use them for other sentences in the bullet point paragraph).

In presentations? First rule avoid bullet points if you can. If you to include some sort of list to make your point on a slide:

• I try to keep the text super short (even shorter than Clare in the above examples)

• Try using some repetition: Higher sales, higher market share, lower costs (“business poetry”)

• And pay close attention to the length of the text I am writing, I want all text boxes to be roughly the same in terms of length. Yes, I admit that I sometimes “stuff” a super short bullet point with a non-essential word to make it look prettier…

Songs written in less than 20 minutes...

A clickbait link popped up on my phone with songs that were written in less than 20 minutes (I am linking to another post with the same subject).

Yes, these songs might have been written in 20 minutes, but I am sure that those 20 minutes are the result of years of practice, trying, and noodling by these musicians. All that effort that was built over a long time just fell in the right place.

I think this is true for every creative process, including presentation design and storytelling. In Hemmingway style: ‘gradually, then suddenly”, Seth Godin talks about it in “The Dip”, a tank filling up drop by drop until it finally bursts with great force.

Server move

I will be getting back to writing blog posts as we are slowly moving towards autumn.

Over the past weeks, I have been preparing a switch of cloud infrastructure provider for SlideMagic to Amazon AWS. The second (stealth) project I am working on requires a very high level of security that could not be delivered by the existing platform. It is amazing what infrastructures you can put together in 2021 at the click of a button.

I have just switched the SlideMagic backend over to the new servers (sweaty palms…) and everything seems to be working OK. I know that there many pioneer users among the readers of this blog, if you spot anything unusual happening, please reach out to me at jan at slidemagic dot com.

Shuffling

Another slide makeover. I will post the ‘after’ before the ‘before’, since the email delivery service sometimes does not render all the images I put in my blog posts…

And here is the original, created by The Information

What did I change?

• I shuffled rows and columns to get the biggest possible continuous space of similar blocks, this is visually more pleasing, and groups/ranks players in a better way. (Hmm, should have swapped Instagram and TikTok now that I look at it).

• I changed the colors, the traffic light analogy does not really work here. The “yes” and “testing” should be very similar in color, while the “no” should be a clear gap.

• I added a more punchy headline

• I calmed the whole chart down by simplifying the legend and taking out the logos.

I have added the slide to our template bank. Users of SlideMagic (try it, there is a free version), can access the slide by searching for “social” in the template bank.

Leaving the math to your audience

It is raining COVID statistics in Israel as we are the first country in the world to deal with a post-vaccination outbreak. Below is one table that was released by the Ministry of Health (I found it here).

I have translated it in a quick SlideMagic chart (it always puts a big smile on my face to see how quickly this can be done).

But this data is horrendous to understand. Percent of what? What is 100%? The audience is left to do the math themselves. Compare the categories to the breakdown of the population, look at differences between 3 and 7 days ago, look at the ratio between mild to severe, etc. etc.

Using bars instead of numbers (another smile) makes things a bit clearer.

But in this case, it would have been clearer to release the data in absolute numbers and let people construct their own charts.

I have added the charts above to the SlideMagic library, search for COVID in the app and the slides will show up (see the search here).

Summer break.

As usual, I am dropping the frequency of blog post for a few weeks in summer, I hope you all have a relaxing holiday.

"Empty" images

When looking for images for your presentation (SlideMagic has a great built-in image search engine), consider searching for images that are relatively “empty”, i.e., images with a lot of white space. This allows you to set them as the background for your entire slide. See the example below.

Pick your keywords to find these type of layouts: empty, background, wallpaper, sky, cliff, horizon, etc. etc.
