Why you're NOT a Software Testing Expert, probably

I see it often on people's profiles and CVs, Expert. It's one of those words that get my attention straight away - and is often badly defined. I'm sure that trying to work out where you are, on a scale from clueless to expert, is something I'm not alone in doing. I was recently invited to review a training course on the basis feedback from an expert like me would be useful. Hmm...

In a recent set of interviews for my next contract and (shock) a permanent role, I've been thinking about this more than often, as you would. It's important to be clear about what you do and don't know, then answer truthfully... no really ;). In some of the calls I've been asked to rate myself on a scale of 1 to 10 either for specific skills and technologies or say as a tester or manager. This creates a problem, given my expectations of what an Expert is, being set so high. The problem being, I rank myself much lower than perhaps I would be expected to say. I could state big numbers, but I don't have an ego the size of a planet. I probably don't have 'marketing' smarts either.

Thinking through what an expert or a 10 is, I came to the conclusion that people at this level are almost unheard of, certainly rarely encountered and almost definitely not doing telephone interviews. That's why you're probably not an expert, probably. We could argue on the 'label' but let's use Expert as the top and Clueless as the bottom. I'll make up ones in between. The reason you're probably not an expert is due to the second issue, the labels are used too broadly.

Imagine I introduced myself as an Engineering Expert, Medical Expert, Physics Expert, Agricultural Expert, Legal Expert. You would immediately need to ask "In what field?" or maybe "In what area?". These descriptions are too broad. There's no way you're a 10 in brain surgery and a 10 in gerontology, you won't be a 10 in family law and a 10 in contract law, you can't be a 10 in civil engineering and a 10 in aeronautical engineering. You can't therefore be a 10, a Software Testing Expert. By definition it doesn't make sense.

Just at a high level we could break testing down into say Functional, Performance and Security, though we could add in other major testing areas. Straight away with just these, I'm sure you'll agree we all know people who are more 'expert' in some of these areas than others. Add in that there are people who focus on test management or on the other end of the scale perhaps automation. Even then, when we say "they're an automation expert", we mean they have expertise in a certain set of tools, technologies and techniques (TTT).


OK then, so when asked to rate ourselves and if we're an expert how might we define that?


On a scale of 1 to 10...

1 - Clueless
You have no awareness of the TTT. When someone says Git, Capybara, C and Java to you, you think it's about animals who are idiots living across the sea on an exotic island.
But hey, well done for reading this blog, stay a while, click an ad. Now go and get yourself the ISTQB Foundation certificate and become a real expert! (that was a joke...).


You resolve to continue pushing yourself. Perhaps there's more to you than you thought.

------------------
Given the above, the rest of us fit somewhere after. However, one more refinement, we don't need to worry about exact numbers. In any given role your skills and aspects of them, will be needed to a greater or lesser degree. "about a nor n, depending on the demands of the project" is a reasonable answer when asked about your skill, on a scale of 1 to 10.

------------------



2 to 3 - Beginner
At this level you've been exposed to the technology, though your understanding of it is limited. You are starting to remember what you are shown step-by-step to do, though constant guidance is needed when encountering issues outside of direct tuition. As a beginner you won't yet understand how the TTTs fits into the overall testing domain. You may recognise the need, e.g. why continuous integration is a good idea, why end of day reporting is valuable, but you carry out tasks as shown, in a rote fashion. With more practice, you start to take on more complete tasks under guidance and begin to need less day to day reference to mentors or help sources.


You realize that all your life you have been coasting along as if you were in a dream. Suddenly, facing the trials of the recent past, you have come alive.
 

4 to 5 - Able
Now you've started to gain some ability to use the TTT day to day as expected. You're fully comfortable with the basics and have started to understand why the TTT is needed. In addition, you now start to see what value it adds, how it integrates with and supports other TTT. You can be readily delegated to but might not always be completely successful or fully efficient in using the TTT to complete a task. Some remediation by more experienced staff might be needed, though when given you gain useful insight into whatever was previously unclear and make positive advances in your overall ability.


You sense yourself more aware, more open to new ideas. You've learned a lot about Software Testing. It's hard to believe how ignorant you were -- but now you have so much more to learn.


6 to 7 - Capable
At this level you're able to carry out whatever needs to be done, with guidance and support not expected to be needed. You fully understand how the TTT works and integrates with others, have insight into common and more obscure issues and problems that occur. You can now start to mentor others in the team and comfortably bring the TTT to projects as part of your professional tool-kit. When thinking of what you 'do' and how you work, the TTT will be part of how you define yourself and your capabilities. many sources of information on the TTT and others people's understanding of them are notably less than yours. You may start to find it difficult to discover new ways of improving your understanding and use of the TTT because what's to learn is getting less and less mainstream, more difficult to find.


It's all suddenly obvious to you. You just have to concentrate. All the energy and time you've wasted -- it's a sin. But without the experience you've gained, taking risks, taking responsibility for failure, how could you have understood?


8 to 9 - Competent
Once you become competent you've gained a full professional understanding of whatever TTT you're working with. By definition you are now possessing all the necessary ability, knowledge, experience and skill to do something successfully, efficiently and with complete consistency. Doing it with your eyes closed... on auto pilot... hardly thinking about it - are all phrases that people are whispering behind your back. You will certainly understand the shortcomings and limitations too, identifying ways to work around them or improve them and integrate with other TTT. By now you'll be known as a key go-to person for the TTT in the profession and likely blog or write on the topic. You competency is so complete, that you can begin to subvert the methods and reasons for using the TTT to deliver unexpected improvements and start to re-wire the ways of working and benefits derived.


You're really good. Maybe the best. And that's why it's so hard to get better. But you just keep trying, because that's the way you are.


10 - Expert
There has to be a level that is the absolute pinnacle of knowledge and expertise, a level so high it cannot be surpassed. This is the level 10 Expert.


To be a level 10 Expert you invented the TTT, several years ago and others are still playing catch-up. You published a book on it and/or get speaking engagements to explain the awesomeness to the masses. Alternatively, you have gained such a level of understanding that you have gone back to the inventors and pointed out where they're getting it wrong, heck you probably decided they're so missing the point that you went and spun off your own TTT to show how it REALLY should be done. You don't look for jobs with this TTT, they come to you.


You'll never be better than you are today. If you are lucky, by superhuman effort, you can avoid slipping backwards for a while. But sooner or later, you're going to lose a step, or drop a beat, or miss a detail -- and you'll be gone forever.

(it was going to be this, but the above was wittier ;} )
