Can’t Beat Experience!


It has been awhile since I’ve written and its mainly because i have moved into the “academic” side of testing – delivering software testing courses for Software Education in New Zealand. As a result i have been busy travelling and delivering!

One of the main things that I’ve noticed during the course delivery is  the degree of separation between a junior test analyst and someone with more experience. At the end of the day, it appears to come down to how many more stories or experiences that someone who has been in the *game* longer has to draw on. This lead me to think about a quote from W.Edward Deming:-

“Experience by itself teaches nothing.” This statement emphasizes the need to interpret and apply information against a theory or framework of concepts that is the basis for knowledge about a system. It is considered as a contrast to the old statement, “Experience is the best teacher” (Dr. Deming disagreed with that). To Dr. Deming, knowledge is best taught by a master who explains the overall system through which experience is judged; experience, without understanding the underlying system, is just raw data that can be misinterpreted against a flawed theory of reality. Deming’s view of experience is related to Shewhart’s concept, “Data has no meaning apart from its context” (see Walter A. Shewhart, “Later Work”). – http://en.wikipedia.org/wiki/W._Edwards_Deming

From my perspective, the more “battles” one has been in, the more experiences to draw from (even if one has “only” been in one organisation) and to some extent, the approach of the test analyst (Agile, Automated, Exploratory, Scripted, UAT etc) may not been as relevant as it serves to broaden the range of ones knowledge.

When i first started testing, one of the theories that i held/learnt was that testing breaks software. When i was asked what i do, i would often respond “I test  software by breaking it”.

Over time, associating with different projects and talking to many people, i view testing as Archeology – we sift through the dust and dirt using whatever approach is necessary to uncover the bugs – the software is already broken – we look for clues to find where these may hide!

Therefore, as testers, it is up to us to find our theory – whatever or wherever that may be. Seek to learn, broaden your skills and then apply this theory when getting your hands *dirty* . This will help to broaden our experience and maybe, just maybe, our individual value as a tester!

BTW – I’m currently reading an Introduction to General Systems Thinking by Gerald M Weinberg – so I’m beginning to walk the talk!

Happy learning!
