The power of Event Modeling lies in its simplicity. This cheat sheet summarizes the four building blocks that can be utilized in four different patterns.

When you host an Event Modeling session, it is good to get people on board quickly. Use this sheet for your own understanding or bring it to a workshop in order to make the start easier for people that are new to Event Modeling.

Natural Human Thinking - Event Storming vs Event Modeling

Tue, 16 Jun 2020 19:15:58 +0000

IT seems to mimic so much from how the human brain works. Similarities are striking. It’s just as if we were to build an artificial brain, sic. Let’s dive in:

human short memory (example: you can repeat a sentence that you heard, but not yet understand it) vs processor cache
human operation memory vs well operation memory (RAM)
human long term memory vs disk space

Let’s imagine the brain as a machine that processes information. It can learn so fast, process loads of data instantly. How it acquires information/learns - this how we should gather requirements for IT systems. So how is knowledge constructed, where is it stored and how?

Great User Experience Demands Event Modeling

“Context Without Measures is Helplessness; Measures Without Context is Chaos”

It is no surprise that my five-year old son thinks that Google Home is a person. He talks to it like a person; giving thanks when it does what he wanted, and gets exasperated when it doesn’t. Given this context, what would great software be like if it was a person? I would argue that a hallmark of great software is that you think of it like a servant, or better yet, a butler. If we have one, what characteristics would such a person have? I would argue that great software user experience, like great people, provide the right context and measures to act upon receiving the context.

Event Modeling Traditional Systems

“Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won’t usually need your flowcharts; they’ll be obvious” – Fred Brooks, author Mythical Man-Month

This fundamental insight is an idea that will allow us to use a much simpler methodology by which to describe systems - almost any information systems. By focusing on state and not the logic of a system, we can infer what it is doing instead of being burdened by the minutia of the details of automation. This is the premise of Event Modeling: shed the low-value aspects of system design the industry has adopted. It extends “specification by example” into the realm of system design.

Event Modeling: What is it?

Motivation

Moore’s Law

Digitized Information Systems are a relatively new concept. Humans have been working with information systems for thousands of years. Over centuries banks, insurance companies and many other large scale organizations have managed to succeed.

With the advent of the transistor, the speed and accuracy of processing information increased by orders of magnitude. What did not gain the same quantum leap is digital storage. This imbalance caused information systems to be optimized for a very small amount of online information. You can see this in the advent of RDBMS technology. What it means is that the compromise was to throw information away.
