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 […]

Contemporary Quality Engineering

Some randomish thoughts on quality engineering.  Quality engineering enables visualisation of the state of quality anytime in the delivery lifecycle of a system or service. It does so in terms of its business outcome.  Anne-Marie Charrett  (working definition) Services not Products  The complexity and the distributed nature of our systems today means we are moving […]

Sometimes the thought of making ‘big’ decisions gives us that ‘rabbit in the headlights’ look.  ‘Big’ decisions often have outcome can have a significant impact to either ourselves or our company. Lack of information can make these decisions harder to make. Constant decision making over sustained periods of time, and having to make decision in high […]

There’s plenty of pages giving you links to API Software Testing. Right now in MoT 30 days API Testing Challenge, they are working on collating lots of these which is a great idea.  I wanted to contribute using a different approach. I decided to collate and amplify material created by female (and those identifying as […]

Lethal Weapon

I’ve spent a day testing a scheduler using a semi-automated technique. It’s a task that is cognitively demanding. It requires creating sophisticated test data, loading it into a scheduler, then identifying if the output is as anticipated.  Sound’s interesting right?  It is. There are lots of different scenarios to test and lots of different dates […]

Embrace your inner strange

As a tester, there are times you’re going to face pushback, ignorance, and disrespect. I say, pick your self up, don on those red party shoes, let your hair down, turn the music up and let’s get this party going!

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 […]
