Some usage scenarios

Introduction

Usage scenarios are what drives the design and construction of the "Bachelor's Kit", but they also help us test it to make sure everything works as planned.

Ordinary scenarios

In theory, if I respected the design method, I'd list here the most representative scenarios of use. For example, we could have scenarios like "Waking up and getting ready to go to work", or "Having a good night of sleep", or "Doing the week's laundry", etc. It's not that these scenarios are irrelevant, on the contrary! It's just that they are all very well known by everybody, so I don't insist on them. We know the "Bachelor's Kit" has to help us live in those scenarios.

Overview of some typical worst-case scenarios

It doesn't make much sense to build a "Bachelor's Kit" for ordinary circumstances only. If you have plenty of time and money, and you never have any problems, then any approach to your material life will work! What we want is something that will also perform well under more difficult circumstances.

Another way of explaining this is to use "Risk Management" or "Disaster Preparedness" jargon. You want to make a list of risks to your material life, evaluate the probability of them happening as well as the damage that would result if they did, and finally you want to "mitigate" those risks. A third way of saying the same thing is: "Hope for the best, plan for the worst".

Here are some typical risks, or worst-case scenarios:

1) You lose your job. For whatever reason, you lose your source of income.

2) You need to move far away and quickly. For example, you need to evacuate your apartment quickly and permanently because a accident in a nearby chemical plant, or a hurricane, etc. This scenario is divided into at least three "sub-scenarios", depending on how much time is given to you (say for example, thirty seconds, or thirty minutes, or thirty hours).

3) Some or all Public Utilities stop. For example, an ice storm causes a power outage that lasts for weeks, or something contaminates the water supply, etc.

4) The whole place burns down. You come back from work, and your apartment is razed by fire. All you have left are the clothes on your back.

5) Somebody steals all your data. For example, your computer is stolen by criminals who will try to steal your money and harm you, using your confidential data.

6) Criminals invade your home while you are in it. Why should criminals work hard to rob you? They can just kick down your door while you're sleeping at night, then threaten to kill you, then have you hand them your money, your car keys, your bank PIN number, etc.

7) You become mentally or physically incompetent. Whether because of old age, or head trauma sustained in a car accident, etc. You keep on living, but you can't work or even take care of yourself.

Some ideas on how to test these scenarios

The "Ordinary scenarios" will be tested everyday, just by living your life, so that is not a problem.

Some of the "Worst-case scenarios" are testable only by "thought-experiments" (like being in a serious car accident and becoming a quadraplegic, etc.). But it's not because something can only be tested in a "thought-experiment" that you shouldn't perform that "thought-experiment"! You still need to test your preparedness!

Some of the "Worst-case scenarios" can be at least partially tested in more realistic conditions. For example, you could ask one of the persons sharing your apartment to sneak into your room some day during the week, and hiding an alarm clock set to go off during the night. When it goes off, you can imagine that the place is on fire, that the electricity has been cut off, and force yourself to be outside within a minute. Don't underestimate the value of such tests, no matter how silly they seem. (The last time I tried this, I got pretty confused in the dark and decided to add another flashlight to my kit, and keep it at my bedside.)

Until you've tested your "Bachelor's Kit" against these scenarios in fairly realistic conditions (or with careful "thought-experiments"), assume you don't really have a kit.
