Musings on The Single Source Of Truth

One of the advantages of being part of the ISST is the fantastic opportunity to dig into topics & ideas with a community of critical thinkers. There is nothing like a good Skype IM chat to sharpen your own thoughts & beliefs!

The other day, the topic of “single source of truth” arose. Who had heard of it? Is it actually a thing?

This post is my attempt to improve my understanding of Cynefin & how it can be applied to software testing.

Why was that bug put in code?

I need to fill in some gaps regarding the quote taken from my recent talk at the BBC Develop 2014 conference.

I told a story of when I was asked the question:

“Why wasn’t that bug found in test?”

I responded:

“Why did you put that bug in the code?”

I have to confess, this isn’t my default response to that question, but as always there’s a story behind the story…
