While the words in the title were never actually said in Apollo 13 control room, they are now forever interlocked with space travel. Many things can happen and are accepted – except for this one. I’ve seen many managers using the phrase often enough to trivialize it. More often than not, failure turned out to be a very viable option – the sole that realized. Even NASA, with all their hard work and technology, suffered some fatal accidents – usually quite spectacular.Continue reading “Failure is Not an Option – Well, Really?”
Ever since I started running, my friends encouraged me to participate in competitions. Exactly two years ago, on 9th of April 2016, I did precisely that. Just a 5k run across one of the largest local parks. How hard could it be?
That depends. Continue reading “Bliss of Failure”
I know a guy incredibly fond of estimating development effort for a ‘scrum’ team in hours. Because, apparently, it’s the best tool to increase developers performance.
Ouch. On so many levels. For so many reasons. As the science of engagement screams in pain while dying, let’s just repeat: ouch.
Of course, there are some arguments against the practice. That no two developers share the exactly same knowledge of the product. That no two developers have the same experience. That, ultimately, we learn and grow by failing. That, maybe, for some reason, we have this team-based tool, called story points, which could make more sense. Because ‘this whole scrum thing’ is all about teams, and so on.
It’s a big no, apparently.
And this guy is actually right! Yes, you can use time-based estimates to evaluate each individual developer’s performance! Yes, it will work! For a price, but let’s just leave it to the side.
On the other hand, it takes some deliberate effort.
First, during the planning session, you have to split all the tasks at hand between individual developers. Simply because, my hour will never equal your hour – which works for every single pair of individuals in the world.
Second, you force each of the developers to precisely estimate the level of effort. It may take up to one full day per two-weeks sprint. A money well spent, apparently!
Third, immediately after the sprint you invest some time to assess each individual’s performance and provide immediate feedback. Failing to do so means no learning occurs, hence people never ever improve.
This guy I know fails on all three.
Which is a good thing after all. Their estimates are rubbish, but as long as nobody *really* cares about them, they’re just fine. Yes, the client will complain for a while – but then they’ll become used to it. Just burning some more money sprint by sprint, oh well.
And yet, it’s not the worst outcome ever!
The worst thing would happen if this guy I know would start exercising his power on the time-based estimates. Because every sane individual involved would just quit. Immediately.
There’s another scenario though. If you were an engineer and was mercilessly persecuted for every time your work log exceeded your estimate, what would you do? That’s right. Increase the estimates. Sure, you’d be bored as hell quite a lot – but safe! Long enough to find another job without quitting immediately.
Story points were created for a reason. Use them. They make sense.
On one hand, it takes a lot to make a statement openly contradictory to common sense. On the other, it is remarkably easy to turn it into publicity stunt, hoping to surf the waves of public outrage. The latter one only works if you can actually prove your point. Otherwise, your new astrological sign is that of an idiot, saying something shocking just for social media likes. Which could also mean you’re one of modern day celebrities, famous for nothing but the fame itself. In the good old days, that some misadjusted to reality crave for, things were a bit different. Amongst starlets, playboys, and criminals, scientists often hit the frontpages. Albert Einstein is probably the best known example, with his impeccable reasoning and creativity reshaping our understanding of literally everything.
Apparently, he had some worse days too, and on one of them, he made a statement that is just wrong. Continue reading “Einstein Was Wrong”
