Testing like Top Gun?

Testing like Top Gun

A few years ago I was asked to help a crack remote IT-team from Nagarro (India) to help them with their software testing and quality assurance.
Their assignment then was to create plugins (interfaces) between the client’s marketing Platform (PaaS) and 3rd parties like Microsoft Azure , Google cloud platform and other platforms like Snowflake etc.
There was one catch, little documentation was available and we did not have a dedicated PO (later we got a great one!) and the situation could change by the day.
So, what do you do as a tester then?


Introducing the OODA loop

Well, about 10 years ago a buddy of mine (and great coach) told me about the OODA loop, a decision-model created and used for making decisions quickly.
It was developed by a US Airforce Colonel, John Boyd, for use in air combat where situations change by the second. Remember Top Gun and its great sequel Top Gun: Maverick ?

How I use the OODA loop with software testing

OODA is an acronym for Observe, Orient, Decide and Act.
My first step was to oversee the situation (Observe) and filter the things necessary for my tests. These things I had to combine (Orient) and create the best fitted tests for the product and the current situation (Decide)
And then the testing started (Act).
But what if things changed?
Well, that’s why it is called a loop, and you can start again from the beginning at Observe.
All in a fast and agile way.
Doing this we created interfaces in a fast way and we were always aware of the constraints and possible risks. As a team, not a bunch of individuals!

Alas, after a while the management team wanted to align us with the other teams and with the company’s processes.
Which is understandable because the company became more a scale up.

But, what a time.
It shouldn’t be a surprise I use the same OODA loop for my clients at TestingSaaS and ICT Rebels.

Always a maverick at TestingSaaS, always a step further, sometimes in the danger zone, but then the OODA-loop helps.
See you in the air, I mean cyberspace….

Quantum computing, Cordny, are you mad?

Quantum computing, Cordny, are you mad?

This question I got last week from a peer after I announced on LinkedIn I wanted to dive into quantum computing.

Yeah buddy, quantum computing, QC for short.

On high school I wasn’t a physics fan, but I was always fascinated by atoms and its protons, electrons etc.
Regarding mathematics, geometry I hated, but algebra I was more interested in. Even during my biology study theoretical biology attracted me, but zoölogie was always my keen interest, so I graduated in microbiology and bio-informatics. Recognize the interest in micro?
Durig my testing career my curiosity in how things work at the smallest level continued and I also got more experienced in cloud computing (see my blogs and articles)
And then a few months ago a colleague of mine talked about QC and I thought, seeing the possibilities of cloud computing, combined with QC, thank you Quantum Delta NL, why not give it a shot in 2024? Let’s test it out and create content, or better said: Create Content through Testing. Just like I did for identiverse (UMA!!!!!) and the metaverse startups (Fectar 🚀 )

It’s a kind of deja vu I now have, the curiosity and implementing it, just like I had more than 10 years ago with IAM (identity and access management) and UMA (yeah Eve Maler !)
I do not expect to be a pro at QC, but with my company TestingSaaS I will explore the landscape, test the software in the cloud, talk to the quantum computing experts, and I will write about it. Yes, using all my skills.
One step at a time, or better said 1 Qubit at a time :-).

To be continued!!

PS: I must be crazy, but I like it!
