Making IT Live up to its Promise

Documentation is Unnecessary Until You Need It

IT Leadership,

If you have a fire in your server room, your insurance pays out. Insurance is expensive, but a necessary part of your risk management strategy. For many risks, there is a way to get almost free insurance. Yet few people take it. I am talking about documentation.

A chocolate factory in Belgium didn’t follow its own processes and did not document its production. When kids started falling sick with salmonella all over Europe, suspicion fell on the Kinder egg factory in Arlon. The authorities asked for the production documentation. Because the factory couldn’t provide it, the whole plant was shut down. If they had had documentation, they would have been insured against this risk. They could have shut down just one production line instead of the whole plant.

So the reason you might not be able to get chocolate eggs this Easter is bad documentation.

Productivity at 10 pm?

IT Leadership, ,

They call it “productivity” but it’s more likely just busyness. Microsoft research into the use of their Teams product has discovered there are now three peaks in a day. It used to be only mid-morning and early afternoon, but now another peak has appeared at 10 pm. Euphemistically, Microsoft equates keyboard activity with productivity, but keyboard activity at 10 pm is unlikely to add much value for most people.

The workday has expanded by 46 minutes since the start of the pandemic, and most of that has been after normal office hours. It is a leadership task to preserve the health and productivity of your people. Do your employees work at 10 pm? Are you okay with that?

You Need 8,000 Steps per Day

Spiritual Programmer,

You don’t need 10,000 steps a day. But 8,000 steps a day cuts your risk of dying prematurely by 40%. A big meta-study published in The Lancet gathers data from 15 large studies. They conclude that mortality – your risk of dying in any given month – at 8,000 steps is only 40% of that at 5,000 steps. Every 1.000 steps above 5.000 give you a 10% improvement.

If you believe you already take 8,000 steps per day, I have bad news for you: You don’t. Most people significantly overestimate their activity level. There is only one way to know and increase your number of steps: Count them. Get an app for your phone, or use a smartwatch or fitness tracker. Set a goal of 8,000 steps and find a way to track your progress. You will find that it also improves your productivity and your mood.

What Can and Cannot Be Said

IT Leadership,

Can you say “pay rise” in your company? At Amazon, that would not be possible. The internal social media app they plan to roll out for warehouse workers will filter out words like “union,” fairness,” and “plantation” (!)

Russian author Fyodor Dostoyevsky said, “The degree of civilization in a society can be judged by entering its prisons.” Similarly, the degree of civilization in an organization can be judged by its internal social media.

What does your internal communication platform and its rules say about your organization?

Focus on the Action

Spiritual Programmer,

You control the effort, not the results. If you want to change your life, you can take action today. There is no guarantee where your actions take you – your environment, other people and chance all play a part, too.

That is why the focus of your daily review before bed should be on the action you took today, not the results you experienced.

What Happens if You are Locked Out?

If the software at your cloud vendor has a bad day, it’ll lock you out of your account. And there is nothing you can do about it.

Many Facebook users discovered their accounts disabled last week, supposedly due to a violation of Facebook’s secret “Community Standards.” Even users who had posted nothing or commented on nothing. Facebook says it is investigating.

What will happen if your cloud vendor suffers a similar glitch? Do you have a business continuity plan, or do you simply pause your business until your cloud vendor gets its act together?

Are You Monitoring Your Automated Systems?

IT Leadership, Technology That Fits, , ,

It is hard to anticipate the real world. I’m sure the wet concrete on the road in Japan looked just like solid ground to the delivery robot. Consequently, it happily trundled into the urban swamp and got stuck. The story does not report whether the delivery company managed to get their robot out before the concrete hardened…

This is why you need careful monitoring of all the fully automated systems you are deploying. The first line of defense is automated metrics and their normal interval. For a delivery robot, the distance covered over a minute should be greater than zero and less than 270 (if you have limited the robot to e.g. 10 mph). The second line of defense consists of humans who will evaluate the alarms and take appropriate action. The third line of defense are developers who will fix the software and the alarms.

Too many automated systems are simply unleashed and depend on customers to detect that something is wrong and complain. You want to figure out you have a problem before the image of your robot encased in concrete starts trending on Twitter.

Save Energy Using Boxes

Spiritual Programmer,

Every item in your field of vision costs you energy. Brain scans show that the automatic effort of filtering out irrelevant objects takes power, and the more items you look at, the worse your focus becomes.

You need to see fewer objects. You don’t have to throw anything out (though that is probably good, too). Simply take a number of items that have some relation to each other and put them in a box. 12 USB cables and 7 memory sticks become one object when they go into a box.

Throwing random objects into a box doesn’t trick your brain, however. Looking at a box you know contains random junk actually costs more energy, because now your brain is also thinking about the task of getting the stuff out of the box and sorting it.

Get out a box and remove some clutter from your field of vision. You’ll find that your energy increases. You just might even get around to that task you have been putting off for weeks.

Do You Let Convenience Trump Security?

IT Leadership, Technology That Fits,

Personal data on anyone is available from all the large U.S. social media platforms and ISPs to anyone who cares to ask. The mechanism is an Emergency Data Request (EDR). When law enforcement doesn’t have time to wait for a court order because someone’s life is in imminent danger, they send an EDR. This is simply an email from a law enforcement mail address. To send a fake EDR, you simply purchase a legitimate government email address from a hacker who has breached one of the more than 15,000 police forces in the U.S.

You would never divulge information on your customers based on just a plausible-looking email. But how do you ensure that expediency has not trumped security somewhere in your organization?

Stop Speaking While You Think

Spiritual Programmer, ,

Do you, like, use too many, like, filler words? Sitting in a coffee shop in New York a few weeks back, I noticed that every fifth word in New York English is “like.”

Research shows that people who use more filler words are considered less intelligent, and their arguments are considered weaker. So it’s a good idea to get rid of your filler words. Here is an exercise: Record yourself on your phone speaking on any topic for one minute. Listen to the recording and count how many filler words you use per minute. Like, uh, ah, um, er, well. If you use more than one, you should improve.

Now record yourself again for one minute, this time making an effort to simply say nothing when you need to think. Pause and think instead of just babbling a filler word. People who pause while speaking are considered more intelligent. Listen to your recording and count your filler words. Hopefully, you have fewer. Also, notice that a pause of one second – the time normally filled with a useless word – is not a problem at all for the listener.
