Ever heard that IT is constantly changing? Or that we all need to be constantly learning? Simple in theory, hard in practice even if like me that’s part of what you love about IT. What if you could hack your brain to learn faster? To understand data, situations, and people more quickly? We’ll briefly discuss some common mental models, illustrate them with IT stories, and let you know where you can learn more.
Note: there's very little text in this presentation - I presented it at South Florida VMUG Usercon for the VMUG Theater and likely will at other usercons.
9. I think it is undeniably true that the human brain must work in
models. The trick is to have your brain work better than the
other person’s brain because it understands the most
fundamental models: ones that will do most work per unit.

24. “Creativity is mixing and matching patterns of everything you've
ever experienced or come to know in your lifetime. It's saying
"this is kinda like that." The neural mechanism for doing this is
everywhere in the cortex.”

Mental Models I Find Repeatedly Useful
Start off with intro – Thanks for coming, who I am, ever heard that IT is constantly changing and need to be learning? How to do that? - and then get silent.
You’re welcome for not wearing this.
Ever know a CIO for whom the only answer is “cloud”? Or an IT worker for whom a script is the answer to everything? Or a director for whom “check with the vendor” is the universal answer?
We all know need multiple ways to look at the world….what we’re talking about is….
Talking about is Mental Models - thought process in how we understand the world – how take information, store, and process it.
How do we think?
How do people understand a domain of knowledge?
How do we anticipate the world and make sensible decisions about what to do?
What triggers thinking and reasoning?
Here’s the thing – it’s not automatically wrong….but understanding that’s what is happening helps us decide how to act. (Do we trust that authority? Does that authority have control regardless of what we think?)

Allows us to make assumptions about how things work, understand more quickly, but also unconsciously influences our behavior and decision making.
3. “Well, the first rule is that you can’t really know anything if you just remember isolated facts and try and bang ‘em back. If the facts don’t hang together on a latticework of theory, you don’t have them in a usable form.”
4. “What are the models? Well, the first rule is that you’ve got to have multiple models ‑ because if you just have one or two that you’re using, the nature of human psychology is such that you’ll torture reality so that it fits your models, or at least you’ll think it does.”
Occam’s Razor - Among competing hypotheses, the one with the fewest assumptions should be selected.
Complexity is the enemy of reliability – choose the simplest option if in doubt.Read and tweak every option in the manual.
Hanlon’s Razor - Never attribute to malice that which is adequately explained by stupidity.
Can make an enemy out of someone b/c assume they're out to get you...they're just trying to learn.
Japan gaining market share in automobile industry
US automakers felt reason might be management aside from cheap labour and protected home markets
Detroit visited factories – saw no inventory and thought it must be staged.
Mental Model = Real Plants have Inventories
Perception = Japanese staged fake plants, Potemkin villages, for Detroit execs
Reality = Just-in-Time
See the problem? When you have mental models but don’t realize them. Let’s pull a military term and call it “lack of situational awareness”.
Lean production is an assembly-line methodology developed originally for Toyota and the manufacturing of automobiles. It is also known as the Toyota ProductionSystem or just-in-time production. Lean production principles are also referred to as lean management or lean thinking.

Systems Thinking - Unintended Consequences
(1) Systems Thinking — “By taking the overall system as well as its parts into account systems thinking is designed to avoid potentially contributing to further development of unintended consequences.” (related: causal loop diagrams; stock and flow; Le Chatelier’s principle, hysteresis — “the time-based dependence of a system’s output on present and past inputs.”; “Can’t see the forest for the trees.”)

Availability Bias - “People tend to heavily weigh their judgments toward more recent information, making new opinions biased toward that latest news.”

NASA is flawless. Successful outcomes caused people to ignore disconfirming information, out of spec performance and dysfunctional decision processes.
The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and "slipped the surly bonds of earth" to "touch the face of God.”

Skills of reflection – slowing down our thinking process so we can become more aware of how we form mental models and how they influence our actions.
Skills of Inquiry – how we operate in face-to-facet interactions with others, especially in dealing with complex and conflicting issues – seeing difference between what people say (or we say) and what we do.
