Recently, I started writing code to analyse data from all kinds of financial and healthcare data APIs. The amount of information is endless. Most data sources have some sort of dashboard that allows you to slice and dice data in any way or form you want.

Still, the skill to make sense of this all is pretty much the same as it was 30 years ago.

I remember building a lot of company valuation models where I would sit on the buy side of an M&A transaction. As a buyer, I had to rely on outside information and focus on the data that matters. Often, I found that my model was more accurate than the one of the analyst on the sell side, who lost herself in the abundance of data available.

My workflow in the new abundance of data:

1. Use some sort of dashboard to explore what types of data is available
2. Use a spreadsheet as a napkin to scribble analyses
3. Code the analysis on a small scale
4. Scale up the analysis to a full scale

The crucial step is number 2.

Here is one use for a slide deck: keep a meeting organized.

Yesterday I saw someone preparing a meeting with the following ingredients:

• Zoom, i.e., hard to manage
• Content that can spark heated debates
• Lots of participants…
• …and participants who would like to say a lot

A simple slide deck that might not be essential to get the messages across but organized the preparation and will organize the meeting was the solution. All points are covered (once) and will be discussed in an agreed order

While working on my 9xchange site, I used one of my approaches to present a document. “Pages” that sit randomly on a table or surface (see below).

I use this technique as well for the banner image of this blog, see below.

This effect is very easy to make. Take an empty slide / page in any presentation app. Save the document you want to show as individual images (good old screenshots will do as well). Drag the images on to the slide and tilt them. Add a little drop shadow behind them.

Things are not as random as they seem though:

• The angles of the pages need to look interesting, not all the same, not too different
• The page need to be semi-readable (i.e., not upside down)
• Key headings should be visible and very readable
• You need to decide whether to let pages bleed off the page, keep them 100% in the frame. It will create very different effects
• You should select pages that look varied, and interesting and are presentative of the content of the document you want to show.

Here is a headline from last night’s GOP candidate debate: Christie accusing Ramaswamy of “sounding like ChatGPT”

We might hear this more often in the future when it comes to debates and presentations. Things that make you sound like ChatGPT:

• Highly structured stories: intro, your supporting points, the wrap up
• Very polite language
• Zero human emotion, humor, anger, cynicism, fatigue
• No spontaneous tangents
• Arcs of a few paragraphs each

You get the point. It is similar to “sounding like a marketing content writer”, a style that has been around a bit longer.

When your headline says that your product is not another [FILL IN PRODUCT CATEGORY], the audience will believe that it actually is one…

I love retro advertising. In this Mercedes car ad from 1982, body work painting is ranked by its level of “conspicuousness”. White is the most in your face. Signal red somewhere in the middle. And blue midnight blue is even more hidden than black.

Professional photographs of your team can give a great lift to your presentation or web site. Either individual headshots all in a consistent style, or even better, a group photo of your entire team in one place.

A good photographer will do two things: firstly, make sure that the technicalities such as focus and lighting are perfect, and secondly, try and create interesting crops and compositions.

Having a photographer set your image crop in stone might not always be good though. What looks great in a 4:3 view finder of a camera, can look suboptimal on web sites that need to handle unusual screen sizes, all the way from big widescreen TVs to small smartphones.

The problem usually is that the center composition will stay constant (the subject area of your team that will probably occupy a 4:3 rectangle or square in the middle of your image), but the background can have vastly different aspect ratios.

The solution: have your photographer take a snap which the crop she prefers, but always add a second one completely zoomed out as a backup.

If you forgot to make that second image, you might have to revert to AI tools such as Adobe Firefly to add the missing pieces of background back in.

Firefly is Adobe’s stab at generative AI. I had a quick look at it an and am pretty impressed.

Most current AI image generators make either very cute artificial / fantasy / cartoon style photos, or allow you to create crazy / unreal compositions. For example: creating compositions you would not normally see (an elephant riding a bike), or mixing styles (the US president soloing on a guitar in the style of Van Gogh).

Adobe Firefly is more useful. You can extend backgrounds on existing images, or position objects in pictures. Below are some of my efforts to add a purple cow to an Alpine background.

Here is a basic background. You can now add an object in it. This is the first result after prompting “purple cow”

The placing of the cow is very good, the purple cow itself is totally unrealistic, probably because “purple cow” in itself is not a concept that is very common. You can select alternative versions of the cow that are more realistic (and less purple):

It’s pretty good (although not perfect). Here is the layer that the app generated on top of the background image (I disabled the background layer)

The best feature of the app might actually be the extension of backgrounds. See the example below, the area to the right was added automatically.

Firefly is part of a beta version of Photoshop (it will soon appear in other Adobe apps as well), and as a result requires a bit of Photoshop skill to use it (which will be a drawback from many). You can also access its features via the web interface. Results are pretty good (you can see that Adobe is very good at separating the foreground and background of the image), but the style is still slightly cartoonish.

There are a number of ways you can, or cannot, use titles in your slide. See the examples below. (RSS subscribers might have to open the post on the web to see images).

The classic way is a basic description of what the chart is showing.

The management consulting approach is the message title: write out in a sentence what the chart is supposed to say, and put the description and unit of the data in a subtitle

You can spice things up with an image

And with full image slides, the traditional title does not actually really matter anymore. You can place text anywhere on the image to get your point across. If you are presenting live, you can even omit the exact description of what you are showing

Back in the 1990s, compact disks would show a so called SPARS code. A series of 3 letters that could either be “D” for digital, or “A” for analogue. “DDD” indicates digital recording, digital mixing, and digital mastering.

My late mother in law had a huge classical music CD collection and I would browse it to find a CD to play, when given a choice “DDD” would be my preference since it was clearly a recording of the highest quality.

My mother in law would answer that this was actually totally irrelevant. What matters is the conductor and/or solo artist that delivered the performance. A poor quality AAA recording from the 1950s might have been the best rendering of a particular piece of music ever.

There is an interesting parallel here with presentations: the actual performance and the supporting slides.
