Creating a skills-matrix for t-shaped testers

I believe the expression “jack of all trades, master of none” is a misnomer, as I’ve mentioned previously. Being good at two or more complimentary skills is better than being excellent at just one, in my opinion.

But what about being excellent at one skill, and still being good at two or more? Why can’t we be both?

Jason Yip describes a T-shaped person and the benefits that having t-shaped people on teams brings:

A T-shaped person is capable in many things and expert in, at least, one.
As opposed to an expert in one thing (I-shaped) or a “jack of all trades, master of none” generalist, a “t-shaped person” is an expert in at least one thing but also somewhat capable in many other things. An alternate phrase for “t-shaped” is “generalizing specialist”.

Ideally we’d like to have a team of t-shaped testers in Flow Patrol at Automattic. But how do we get to this end goal?

I recently embarked on an exercise to measure and benchmark our skills and do just this with our team. Here’s the steps we took.

Step One – Devise Desired Team Skills

The first thing we did was come up with a list of skills that we have in the team and would like to have in the team. These can be ‘hard’ skills like a specific programming languages and ‘soft’ skills like triaging bugs. In a standard co-located team this would be as easy as conducting a brainstorming session and using affinity grouping to discover these skills. In a distributed environment I wrote a blog post to my team’s channel and had individual members comment with a list of skills they thought appropriate, and then I did the grouping and came up with a draft list of skills and groups.

Step Two – Self-assess against a team skills matrix

Once I had a final list of skills and groups (see below for full list), I put together a matrix (in a Google Spreadsheet) that listed team members on the x-axis, and the skills on the y-axis, and came up with a skill level rating. Our internal systems use a three level scale (Newbie, Comfortable, Expert) which we didn’t think was broad enough so we decided upon five levels:

1. Limited
2. Basic
3. Good
4. Strong
5. Expert

Team Skills Matrix

I hadn’t seen Jason yip’s visual representation at that point in time, otherwise I may have used something like that, which has five similar levels:

Step Three – Publish results and cross-skill

Once we had the self assessments done we could then publish the data within our organisation and use the benchmark to cross-skill people in the team. In a co-located environment this could involve pair programming, in a distributed one it could involve mentoring and reviewing other team member’s work.

Have you done a skills matrix for your team? How did you do it? What did you discover?

AMA: What sets exceptional QA testers apart?

Dayana asks…

I wondered if you could tell me what sets exceptional QA testers apart? Not just personality or work ethic traits, but specific skills and programming knowledge that will be very valuable to a team?

My response…

I think exceptional QA testers, as explained recently, aren’t people who are exceptional at just one thing, eg. testing, but good at lots of things.

So an exceptional QA tester, in my opinion, will typically have (at least good) skills in the following things:

  1. Skills in human exploratory testing: an exceptional QA tester has the ability to effectively find the most important bugs fast. Whilst this skill can be developed, I have found it’s mostly a mindset.
  2. Skills in developing automated tests: an exceptional QA tester will have programming skills needed to develop automated tests and I would recommend these to typically match the programming language(s) that programmers in your organization use. For example, skills in automated testing in .NET if your company primarily uses Microsoft .NET. Although, someone with strong programming skills in one language (eg. ruby) should be able to transfer these skills to another language (eg. python).
  3. Knowledge/Experience in your business domain: an exceptional QA tester will fully understand your business domain and keep this context in mind whilst testing a product and raising issues. An exceptional tester is always testing your system – just as I am testing WordPress.com publishing this post.
  4. An empathetic mindset: we design and develop software for real people and real life. An exceptional QA tester will test with this in mind.

(Not) Lying about Writing Code

I recently saw this quote in an article by Nikita Hasis on Medium.

“If Your Test Leaders Aren’t Telling You To Write Code, They Are Lying!
Even if it’s by omission.

There’s this argument, almost daily, about whether software testers should learn programming. I’ll jump right in. It is unimaginable that someone would tell you NOT to learn something. That’s the first, and probably shittiest lie that inexperienced testers get fed. It’s further unimaginable, and downright irresponsible to tell people not to learn something that is very clearly where a large, well-paying, and above all interesting part of the industry is heading. Wanna work on innovative, data-driven projects with smart and driven people? You probably need to pull up terminal and at least get your toes wet, y’all.

The worst part of the lie is that it imposes that coding is a difficult grind and will only cause more problems than it solves. I even saw Alister Scott’s blog post referenced as an argument against coding, ironic as it is.”

AMA: the future of QA roles

Lroy asks…

How, according to you, is the future of QA roles going to look like. I currently work as a QA in a matured agile team where the devs are responsible enough to practice TDD and write automated tests while I pair with them. I pair with them on test strategy, performance testing, a bit of security testing. It is definitely an interesting shift to see how QA was perceived to how it is now. I understand that it is not like this in every company. But how do you see this role pan to to be? Thanks PS: Thank you for taking time to do AMA, it is really interesting to read your responses. I have enjoyed reading your blog for couple of years now.

AMA: describing our work

Chris Stanbridge asks…

Hi Alister, Long time fan of this site and your work – you’ve become the quality go-to source of truth for our scrum team. I think I have a similar role as your day job, but I have a quandary: I’m unable to describe what I do at work. Friends and family lose attention part way through my explanation, and I’ve found it has made me appear to be a crashing bore. I’ve developed a recurring nightmare where I fail to summarise the nature of my work to my demons (game-show hosts or stand-up comedians who pick me out of a crowd) who just don’t get it. I thought I was being clever by saying I use a “robot” to check if computer code works, but the picture painted using that word is considerably off the mark. If only I was a plumber… I’m sure you can provide me with a concise blurb I can memorise and plagiarise for the next neighborhood barbeque that’ll make me appear as interesting as I think I am :-) Cheers, Chris PS: Please keep up the excellent and entertaining blog – you’re an inspiration and an education.

My response…

Well, my job title at Automattic is actually Excellence Wrangler which is both awesome (in that no-one has heard of it before), and terrible (in that I have to explain what it is to everyone who asks).

I will often say something quick like “I work with various software teams to create a consistently pleasant user experience on WordPress.com”.

If that’s not sufficient detail I can explain that we continually do lots of testing of various WordPress.com user flows across different devices and browsers trying to find issues and bugs before our users do. We also develop automated scripts that run all the time to help us find these issues quickly since we make changes so frequently.

I’m not sure if that will help you, but since you’re in Brisbane too, let’s catch up and discuss further over lunch and/or tea 😀

 

AMA: QA tools and resources when starting out

Nanthida asks...

Hey Alister!
I’m new to software testing, having come from a Support background, and I’d love to know what tools and/ resources worked best for you when you were starting out? :)

My response…

I very recently answered an almost identical question, so I will point you to my response.

AMA: how to cope as a solo tester

Bodda asks…

hey, i like your blog, i’m reading your blog on a daily basis, and i just want to ask you what i can i do to enhance my skills, knowledge and to be a be good in functional testing (manual and automation) IF i’m the ONLY tester in my current company (performing all testing activities), but i feel that i have a mess in my head and lots to learn to be up to date with the last trends.
my question now “What to learn, When(everyday?) and How in case your are the only tester in your company”.

i hope to answer my question soon to make my head calm down

My response…

I have fond memories of a project where I worked as the solo tester on a software delivery team; we had something like 8 developers (including one lead who took on iteration management tasks) and me as a tester. That was it. I loved it because we established really good unhindered rapport with our business stakeholders, and I was always busy!

But getting back to your question: when I was working in that situation it was vital that we had developers working on as much test automation as possible, alongside functional development, since there was just too much functional testing to do for a single person also doing test automation. I found myself spending about 80% of my time just testing new functionality and spot-testing different browsers/devices etc. The remaining 20% I spent ensuring we had good regression test coverage through the automated tests that developers were writing and I was helping maintain. So first and foremost I would strongly encourage you to get the developers you work with to have as much responsibility as possible for automated tests.

If you have this in place you should be able to take a deep breath and spend more time doing quality testing. I have found the best way to learn is on the job, you’ll be in a good position to do this, and often you’ll learn best by making your own mistakes.

If you want to know more about how to become better at what you do, I’ve shared some tips in a previous answer. There’s also my Pride & Paradev book which I wrote whilst working as a solo tester on a team.

All the best.
