Updated and added to for 2023. This post is a collection of diagrams and methodologies collected over the years, used in teaching and in business. Learn about the curve of learning, the best strategic model we employ, why deadlines are useful, why we all need an alter-ego, and how we ask how are you today? Art and animations by Agate.

When deciding to do a task ahead of signoff. To work out whether you need to make that investment or even back up system.
A really useful tip to work out when to start projects and how far to continue. Thank you to my old Geography teacher who taught these ones.
20/80 Model
Long Tail Model
What?
20% is your target, the rest is “long tail”
When to use?
In countless examples, from SEO, to bugs, to product sales, to influencers its always the 20% “mass” that really matter.
Decision Timeline
What?
The more a project goes on the more fine-grained the decisions are with regards to consequences

Just keep in mind that your decisions have different impacts at key times. Sort of obvious but a model none the less.

When in business, UX, design and especially with developing code. Go with simple.

Always.
The Swiss cheese Model
You cannot stop every bad thing happening
What?
We have built around ourselves many checks and safeguards. All have holes – some more than others. On a really bad day those holes line up and you have a disaster on your hands.

What?
If a task has 2 hours it will take 2 hours. If you have 2 weeks it will take 2 weeks.
When to use?
Planning and action. Shorter timelines are often better and more focused. Longer timelines end up being shorter as you put off the tasks. Short, sharp, focused but finite tasks work better. See also SPRINTS.
Collett’s Law
“No good can come of a phone call after 5pm on Friday.”
What?
Turn your phone off. Go have a drink. If someone has left it that late you are last on their list, or whatever it is needs some more planning or thinking.
Or for you younger folks, the Gremlin Law. No good decisions are made post 12 midnight.
Curve of Learning
What?
At a point in time you are trained enough to be a [insert job title here]

When learning new things.
In university we are aiming for somewhere between the end of year 2 and 3. Some students are ready for the big wide world before others.
Choice vs happiness paradox
Monkeys and Bananas
What?
Especially in UX design any choice, even if just two buttons or items slows you down.
When to use?
Especially when creating a walkthrough or flow, like a booking engine or shop. Make choices for the user for them to confirm, or highlight a recommended choice.
The Diderot Effect
In our house, known as the “French Dressing gown dude”.
When you buy a shiny new thing, then you are happy for a short while, until you notice that all around you is old. The cult of capitalism laid bare.

Gell Mann Paradox
You are an expert in your field. You read an article on that field written by a journalist. You can tell that a percentage of the article isn’t quite right.
Therefore the rest of the articles are also not quite right.
Check your sources and be careful of what you read.
The Gift Matrix
Four Columns
THINK OF YOUR OBITURY NOT YOUR CV
Self explanatory, and a difficult thing when you are trying to earn a living. No one regrets on their death bed not finishing that email. Go hug your family.
Love yourself
You are going to spend an awful lot of time with yourself. Slightly depressing but also liberating.
This last one is not our diagram, see the full graph.
