The Dots


One of the questions that we asked ourselves at CEWT 3 was what we were going to do with the things we'd discovered during the workshop. How would, could, should we attempt to share any insights we'd had, and with who?

One of the answers I gave was that Karo and me would present our talks at Team Eating, the regular Linguamatics brown-bag lunch get-together. And this week we did that, to an audience of testers and non-testers from across the company. The talks were well-received and the questions and comments were interesting.

One of them came from Rog, our UX Specialist. I presented a slide which showed how testing, for me, is not linear or strictly hierarchical, and it doesn't necessarily proceed in a planned way from start to finish, and it can involve people and objects and information outside of the software itself. Testing can be gloriously messy, I probably said:


His comment was (considerably paraphrased) that that's how design feels to him. We spoke for a while afterwards and he showed me this, the squiggle of design:


I saw his squiggle and raised him a ring, showing images from a blog post I wrote earlier this year. In Put a Ring on It I described how I attempt to deal (in testing, and in management) with an analog of the left-hand end of that squiggle, by constraining enough uncertainty that I can treat what remains as atomic and proceed without needing to consider it further, at that time, so that I can shift right:


He reminded me that, perhaps a year earlier, we'd spoken about information architecture and that this was relevant to the discussion were were having right there and then. He lent me a book, How to Make Sense of Any Mess by Abby Covert.


The book discusses information-based approaches to understanding a problem, working out what kinds of changes might exist and be acceptable, choosing a route to achieving a change, monitoring progress towards it, and adapting to whatever happens along the way. I started reading it that evening and came immediately across something that resonated strongly with me:
Intent is Language: Intent is the effect we want to have on something ... The words we choose matter. They represent the ideas we want to bring into the world ... For example, if we say we want to make sustainable, eco-centered design solutions, we can't rely on thick, glossy paper catalogs to help us reach new customers. By choosing those words we completely changed our options.
Covert goes on to suggest that for our designs we list two sets of adjectives: those that describe properties we want and those that describe properties we don't want. The second list should not be simple negative versions of the first and the aim should be that a neutral observer should not be able to tell which is the desired set. In this way, we can attempt to capture our intent in language in a way which can be shared with others and hopefully result in a shared vision of a shared goal.

Later in the book, she suggests some structures for managing the information that is intrinsic to any mess-resolution project. Here I saw a link to another book that I'm reading at the moment, one that I borrowed from Sime, another colleague at Linguamatics: Beautiful Evidence by Edward Tufte.


This book considers ways to improve the presentation of evidence, of information, by removing anti-patterns, by promoting clarity, by exploiting aspects of the human perceptual system. It does this in order to provide increased opportunity for greater data density, enhanced contextual information about the data, the provision of comparative data, and ultimately more useful interpretation of the data presented.

Covert's high-level information structures are useful tools for organisation of thoughts and, in one phrase - "keep it tidy" - with one brief page of prose to accompany it, she opens a door into Tufte's more detailed world.

I had begun to reflect on these things while speaking to another couple of my colleagues and noted that I continue to see value returned to me by reading around testing and related areas. The value is not necessarily immediate, but I perceive that, for example, it adds depth to my analyses, it allows me to make connections that I otherwise would not, it helps me to avoid dead ends by giving a direction that might otherwise not have been obvious.

I was a long way into my career (hindsight now shows me) before I realised that reading of this kind was something that I could be doing regularly rather than only when I had a particular problem to solve. I now read reasonably widely, and also listen to a variety of podcasts while I'm walking to work and doing chores.

And so it was interesting to me that yesterday, with all of the above fresh in my mind, while I was raking up the leaves in our back garden, a recently-downloaded episode of You Are Not So Smart with James Burke came on. In his intro, David McRaney says this, reflecting Burke's own words from a television series made in the 1970's, called Connections:
Innovation took place in the spaces between disciplines, when people outside of intellectual and professional silos, unrestrained by categorical and linear views, synthesized the work of people still trapped in those institutions ...
Innovation, yes, and testing.

Edit: after reading this post, Sime pointed out Jon Bach's graphical representation of his exploratory testing, which bears a striking surface resemblance to the squiggle of design:

The Best Programmer Dan Knows

  I was pairing with my friend Vernon at work last week, on a tool I've been developing. He was smiling broadly as I talked him through what I'd done because we've been here before. The tool facilitates a task that's time-consuming, inefficient, error-prone, tiresome, and important to get right. Vern knows that those kinds of factors trigger me to change or build something, and that's why he was struggling not to laugh out loud. He held himself together and asked a bunch of sensible questions about the need, the desired outcome, and the approach I'd taken. Then he mentioned a talk by Daniel Terhorst-North, called The Best Programmer I Know, and said that much of it paralleled what he sees me doing. It was my turn to laugh then, because I am not a good programmer, and I thought he knew that already. What I do accept, though, is that I am focussed on the value that programs can give, and getting some of that value as early as possible. He sent me a link to the ta

Beginning Sketchnoting

In September 2017 I attended  Ian Johnson 's visual note-taking workshop at  DDD East Anglia . For the rest of the day I made sketchnotes, including during Karo Stoltzenburg 's talk on exploratory testing for developers  (sketch below), and since then I've been doing it on a regular basis. Karo recently asked whether I'd do a Team Eating (the Linguamatics brown bag lunch thing) on sketchnoting. I did, and this post captures some of what I said. Beginning sketchnoting, then. There's two sides to that: I still regard myself as a beginner at it, and today I'll give you some encouragement and some tips based on my experience, to begin sketchnoting for yourselves. I spend an enormous amount of time in situations where I find it helpful to take notes: testing, talking to colleagues about a problem, reading, 1-1 meetings, project meetings, workshops, conferences, and, and, and, and I could go on. I've long been interested in the approaches I've evol

Not Strictly for the Birds

  One of my chores takes me outside early in the morning and, if I time it right, I get to hear a charming chorus of birdsong from the trees in the gardens down our road, a relaxing layered soundscape of tuneful calls, chatter, and chirrupping. Interestingly, although I can tell from the number and variety of trills that there must be a large number of birds around, they are tricky to spot. I have found that by staring loosely at something, such as the silhouette of a tree's crown against the slowly brightening sky, I see more birds out of the corner of my eye than if I scan to look for them. The reason seems to be that my peripheral vision picks up movement against the wider background that direct inspection can miss. An optometrist I am not, but I do find myself staring at data a great deal, seeking relationships, patterns, or gaps. I idly wondered whether, if I filled my visual field with data, I might be able to exploit my peripheral vision in that quest. I have a wide monito

Postman Curlections

My team has been building a new service over the last few months. Until recently all the data it needs has been ingested at startup and our focus has been on the logic that processes the data, architecture, and infrastructure. This week we introduced a couple of new endpoints that enable the creation (through an HTTP POST) and update (PUT) of the fundamental data type (we call it a definition ) that the service operates on. I picked up the task of smoke testing the first implementations. I started out by asking the system under test to show me what it can do by using Postman to submit requests and inspecting the results. It was the kinds of things you'd imagine, including: submit some definitions (of various structure, size, intent, name, identifiers, etc) resubmit the same definitions (identical, sharing keys, with variations, etc) retrieve the submitted definitions (using whatever endpoints exist to show some view of them) compare definitions I submitted fro

Vanilla Flavour Testing

I have been pairing with a new developer colleague recently. In our last session he asked me "is this normal testing?" saying that he'd never seen anything like it anywhere else that he'd worked. We finished the task we were on and then chatted about his question for a few minutes. This is a short summary of what I said. I would describe myself as context-driven . I don't take the same approach to testing every time, except in a meta way. I try to understand the important questions, who they are important to, and what the constraints on the work are. With that knowledge I look for productive, pragmatic, ways to explore whatever we're looking at to uncover valuable information or find a way to move on. I write test notes as I work in a format that I have found to be useful to me, colleagues, and stakeholders. For me, the notes should clearly state the mission and give a tl;dr summary of the findings and I like them to be public while I'm working not just w

Make, Fix, and Test

A few weeks ago, in A Good Tester is All Over the Place , Joep Schuurkes described a model of testing work based on three axes: do testing yourself or support testing by others be embedded in a team or be part of a separate team do your job or improve the system It resonated with me and the other testers I shared it with at work, and it resurfaced in my mind while I was reflecting on some of the tasks I've picked up recently and what they have involved, at least in the way I've chosen to address them. Here's three examples: Documentation Generation We have an internal tool that generates documentation in Confluence by extracting and combining images and text from a handful of sources. Although useful, it ran very slowly or not at all so one of the developers performed major surgery on it. Up to that point, I had never taken much interest in the tool and I could have safely ignored this piece of work too because it would have been tested by
