Information is one of those things where sometimes the whole is greater than the sum of the parts. That is, you get extra value from combining bits of information, on top of the value from the separate bits of information on their own. I’ll illustrate this with an example to do with spies, but then … Continue reading The compounding value of information
There’s a kind of diagram, called a Sankey diagram, that can be used to show relationships between things. I will briefly introduce it, and then use one to illustrate Coronavirus and Covid19 in the UK. It will simplify things, but I hope will still help you get a better understanding of how the various numbers … Continue reading Sankey diagrams to explain Coronavirus and Covid19
Someone I know was moaning recently about a lot of tedious electronic form filling they had to do for work. It was something that happened once a year, but it was much more lengthy and tedious this year than before. It struck me that this was a sharply focused example of when user experience (UX) … Continue reading User experience (UX) and data quality
As well as refactoring existing unit tests, I’ve also recently created some tests from scratch. I realised that, while I have gone on at length about testing on this blog, including the ways in which I think tests can be well- or poorly-written, I haven’t talked about the process of writing them. In case it’s … Continue reading Creating unit tests from scratch
I recently made a code change, and also made the corresponding changes to the unit tests. Once that was sorted and tided away in a commit, I spent another commit refactoring the unit tests. As I was refactoring, I realised that the motivation behind the refactoring, i.e. what was influencing its direction, was a desire … Continue reading Panning for meaning in unit tests
I live in a place that has a river flowing through it. Like in many places in the UK, we have had floods this week, which has been stressful for people whose homes and businesses have been affected. Fortunately, we were OK and no-one here was affected too badly. As a complement to the stress … Continue reading Analysing flooding rivers
I recently received a letter from my bank that was meant to explain something, but it didn’t. This reminded me of a fruitful conversation I had with someone on the Ministry of Testing slack community, about what motivations people might have for writing. In this post I’ll try to dig into that a bit, in … Continue reading What motivates your technical writing?
In my previous post, I contrasted two different terms for thinking about how people interact with your organisation – Customer Experience (CX) and User Experience (UX). Rebecca Brown (a CX expert I mentioned in the post) kindly explained her view of CX to me, which got me thinking of some quality and process things that … Continue reading Customers, suppliers and fences
I’ve heard both Customer Experience (CX) and User Experience (UX) used to describe how someone’s life is changed, for the better or for the worse, because of the goods or services that an organisation provides. This article goes into my understanding of those terms – how they’re similar and different. I don’t think that either … Continue reading Customer Experience or User Experience?
If you have a website, it's probably to fulfil some purpose - to let people buy something, or look something up etc. This purpose can be articulated as a series of requirements (functional or cross-functional), which can be ticked off during testing. In this article I will use some buildings to illustrate a point about … Continue reading Does your website reassure and welcome?
