The business value of testing

The business value of testing is directly correlated to testers’ ability to provide quality related information that either increase the chance of higher revenue or decrease the risk of higher costs for the company.

An important implication of this is that the higher revenue or lower cost must be greater than the cost related to the testing effort that provided the information in the first place. That can be a slightly uncomfortable insight for testers to make, but it’s an essential thing to keep in mind when we try to determine whether we should stop testing or not.

A more positive way to frame it is that we must continuously ask ourselves if there’s something more important that we could be doing at any given time, i.e. we must be aware of the opportunity cost of testing. Ask: Why am I testing? What kind of information am I looking for (a.k.a. information objective)? Is there potentially more valuable information to be found by modifying the way I’m testing or by testing some other aspect of the product?

From time to time we must also realize that our curiosity as testers will never be completely satisfied and we’ll more likely than not be forced to stop testing and ship the product before we’re comfortable with doing so. That feeling is of course a positive thing. It should feel a bit uncomfortable for testers to ship. If you’re completely comfortable with shipping the product then you’ve probably spent too much time testing in relation to the business value you’ve produced, or you just don’t care. Either way, I wouldn’t want to work with a tester who didn’t feel some sort of internal resistance when confronted by the PM calling “time’s up!”.

This is my first attempt to lower my personal bar for how long or thought through a blog post needs to be. It came about in a conversation about business value on the Swedish testing community’s Slack team http://testsverige.se/ and this blog post is essentially an exact copy what I wrote on Slack in that discussion. Anyway, I hope this has some value to somebody. My goal with this experiment is to get better at not preventing myself from publishing half-baked thoughts, which I regularly do (the preventing bit), which results in nothing getting published ever… A lot of you can probably relate to that feeling…? ūüôā

Listen up and read

In the technology adoption lifecycle, I usually fall somewhere in between the early adopters and early majority. Every now and then though, I find myself among the last of the laggards. Case in point: audiobooks. I’ve discovered their usefulness just a couple of decades after mostly everyone else. Turns out, audiobooks have¬†proved themselves a highly efficient way of getting through the pile of shame that is my ever increasing “to read”-list.

And grown it has… since the birth of my first child little over three and a half years ago I’ve not read a single book. Not even one. I started reading a few, but I soon ran low on time, and after collecting dust for a couple of weeks, it became apparent over and over again that I would probably have to start over if I wanted to pick them up again. After becoming a father of two, time has become an even more precious commodity.

That’s why this thing with listening to books excites me, and why I want to tell more people about it (even though I’m probably among the last people to the party). I’m sure I’m not the only one out there who struggles to find the time to sit down and do some serious reading.

I got started after listening to one of my favorite podcasts: Dan Carlin’s Hardcore History. He (and many other podcasters) is sponsored by Audible.com, and since I didn’t know anything about audiobooks, and because I could support Dan by signing up through his website, that seemed like as good a place as any to try things out at. I downloaded the Android Audible app, created an account, and found a few books to start building my library.

In one and a half years I’ve now gotten through 37 books, clocking in at roughly 300 hours or the equivalent of somewhere around 11250 pages. That’s more than zero. Some would say a lot more than zero. (I would.)

Since I can “read” these while doing other monotonous things (mowing the lawn, cooking, doing dishes…), I get plenty more opportunities to read compared to if I would be forced to sit down in a quiet space in order to get some book time. This in turn has afforded me the opportunity to go beyond books that I would normally read and dive into a few classic books that I would otherwise never find the time for, like the Thomas Paine books (“Rights of Man”, “Common Sense” and “The Age of Reason”) which I’ve been eyeing for quite some time, or John Stuart Mill’s excellent text¬†“On Liberty” as well things from the opposite end of the liberty/humanist spectrum, e.g. what seemed to be a pretty good translation of “Mein Kampf” which was both fascinating and frightening. I’ve also fulfilled a promise to my wife to read “Brain Rules for Baby” by John Medina, which turned out to be quite insightful.

I also very much enjoyed the much more political and autobiographical books by Maajid Nawaz and the extraordinary Ayaan Hirsi Ali, and of course the insightful books by one of my personal heroes, Sam Harris, who seems to move with ease between a wide range of topics like religion, morality, politics and secular spirituality. Very much looking forward to his upcoming book on artificial intelligence.

For those of you who are working in software testing and/or are entrepreneurs, I especially recommend the fairly short books by Seth Godin in the list below, as well as “The Challenger Sale”, “Your Brain at Work”, “The Power of Habit” and also of course the Malcom Gladwell books. I found I could both digest and retain them all fairly well in this format.

The only drawback to my “method” is that there aren’t many tech books in an audio format. At least not that I’ve been able to find. But hey, no system is perfect, but some are useful. I’ll probably keep chipping away at my now somewhat shorter pile in this way for a good while longer.

What’s your favorite audiobook? I’d love to hear your recommendations.
