threats to quality

Threats to Quality

If, as Gerry Weinberg states Quality is “value to some person” …then the corollary stands that risk is anything that threatens that value.  This can be useful because Quality is an amorphous, shapeshifter, notoriously difficult to nail down. Its final judge is not us but our consumers.  I compare quality to a Black Hole. We can’t […]

Emergent Quality

If you work in software development, like I do, you most likely work within a complex system. You also, most likely, work on a complex system. Not sure? Try answering these questions: Is it hard to model your system in all its complexity? Is it hard to work out root causes to identified problems? Is it hard […]

There are lots of different scenarios to test and lots of different dates […]

Beyond the Black Stump

In Australia, the black stump is a metaphor or the edge of civilization., an imaginary beyond which point at the country was considered remote.  There’s a whole lot of value of testing what we know. It helps create a mental model of what the system does. We can start making sense of what the system is […]

Whose moved my risk?

We know quality is ‘value to some person’, so it stands to reason that risk is also subjective. If we use risk as a factor to determine what to test, then how you test, what you test and your testing strategy will evolve and change. Is it though? Think of testing within your organisation as […]

Blogging on the Bus: An imperfect series

I have more draft blog posts than published and I have a lot of ideas I want to write about. I’ve challenging myself to write short imperfect blog posts that I can write on my bus trip to work. That’s about an hour. They will be rough and not edited but hopefully, you will get […]
