Disclaimer: Purpose of this blog is not to undermine the importance of automation skills for testers but rather to highlight the lack of awareness in our industry for tester's usefulness in teams beyond typical testing and automation tasks.
Recently, I was invited to conduct a workshop around "Whole Team Testing" at Test Leadership Congress in New York. Participating in this conference has been a great experience, especially because I truly believe in the need for conferences dedicated to test leadership and career path for testers in changing era.
The discussions I had there with fellow testers, managers and directors of engineering/testing were interesting. Well, not only interesting but insightful and with lots of ideas, concerns, observations to ponder upon. Out of the things we discussed, what held my attention the most was the growing concern of evaluation of testers in Agile teams. The evaluation can be for hiring or for their overall performance in team.
What is the problem exactly?
If you analyse the trend from State of Testing report, it is evident that with increasing Agile adoption, centralised testing units are mostly getting dissolved and testers are now reporting to Dev/Team leads. With this change of structure, hiring new testers and evaluating those in teams naturally becomes the responsibility of the Dev/Team leads. And this is where things start to get interesting. How? Let's take a look:
But this situation is dragging us into bigger problem. We are giving too much importance to things that are just a part of big scheme of things that matter and contribute to software quality and teams' overall ability to ship quality software, faster and frequently.
Of course automation skills and other technical skills are helpful, rather important I would say. But that has become a norm now and what we really need at this point of time are tools to see beyond this norm. If we want excellent testers in team who can really add value to software quality, it's high time that hiring managers come out of their obsession of hiring testers based on the norms that they can most comfortably evaluate. Please, it is not about what we are most comfortable with but what Agile team really needs from a tester to ship a quality software.
Heavy emphasis on technical skills for testers is not my big concern, but lack of awareness around other things that testers must get evaluated against, concerns me the most. Purpose of this article is to highlight some of those areas (beyond typical technical skills) that I think managers/leads may want to consider while hiring new tester or evaluating those in their teams.
Why do we need testers at first place?
One may argue that in an era of AI and advanced automation where every check can be easily automated, why do we need human testers at all? That's interesting argument and before I explain why we are talking about it, I want you to have a look over the diagram below:
The diagram represents a system that we as a team operate into. I created it based on my experience as a tester so far and by interviewing some programmers I have closely worked with.
Looking at bunch of things mentioned there, you can figure out what all can happen (rather typically happens) when tester in team is not available. If you read the diagram carefully, you will notice that impact on finding and reporting bugs is just one segment that gets highlighted when tester is missing in team. Impact on writing new tests or automating them is another segment. But is that all you need testers for in a team? Certainly not!
The purpose of having testers in team is way beyond finding bugs, writing tests or automated scripts for that matter. If utilised to their full potential, testers in team can very well serve as a mode to protect your system from running into collapse or explosion mode (please read more about that in "How Software is Built" by Jerry Weinberg). How? It's simple. By providing system related feedback to the controller which is typically team lead or test manager in typical team set-up. The better you utilise tester for their abilities the better feedback you get from them which in turn can help you command better control over your system and protect it from collapse/explosion. You need tester in team to provide you with information that you as a stakeholder can use for making better decisions.
And when I say feedback, it can be anything from information about bugs, risks highlighting, asking context revealing questions, questioning user stories or decisions made, finding out historical data, highlighting third-party dependancies, sharing news about decisions made by cross functional teams, collaborating with other disciplines to create valuable assets, their observation around team dynamics, their predictions about possible failures and so on. And if you are lucky, they can also tell you some great things about quality of your product.
The point is, tester in your team can add far more value beyond finding bugs, if you allow them to contribute beyond their typical role. If not, you can always empower them to do so. Here are couple of things that in my experience testers can contribute to and against which you could evaluate them (for hiring or performance reviews etc):
1. Primary analyser of production logs and alerts
Production deployments are typically done by programmers who then closely follow the logs to see if there are any obvious issues created by latest build. Consider handing over this responsibility to testers. It is likely to serve multiple purpose:
2. Enhancers of your product's coverage for quality
It has very little value if tester in your team just sticks with usual acceptance criteria for the ticket and automates the stuff for you to top it. The real value a skilled tester can add is when they question the very product coverage you have in place and help your team see elements of product that matter from quality aspects.
A lot of elements matter when it comes to your product's quality. Functional acceptance criteria is just tiny part of it. A skilled tester would know about these elements and they would educate the team about same.

3. Advocates for Testability
Testability is one of the key area I would expect skilled tester in my team to help programmers and designers get it right. A skilled tester would know what makes product testable, how to evaluate it for testability and also advocate the team as in where and how they can improve it. Nothing beats the pleasure of testing better testable product.
Here is a heuristic for testability if that makes you curious. Out of various types of testability mentioned there, I would expect the tester to at-least know Intrinsic Testability and how to help their team improve it.
4. Better allies for UX peeps
Ever wondered what would happen if System Thinking meets Design Thinking? I firmly believe that challenges faced by testers and UX professionals are more or less same when it comes to ensuring better quality and better user experience.
A regular and close exchange between these two disciplines has tremendous potential to create a better user experience with enhanced product quality which I would call as "Quality Experience". If UX designer comes with one best solution for some product problem, a skilled tester with their insights, product knowledge, awareness around cross-functional dependancies can point out variety of ways in which it may fail. This does not mean a tester has to criticise UX solutions as such but early collaboration and exchange between two can help avoid lots of unnecessary research and rework.
On other hand, testers can borrow realistic information from UX's research which can help them design tests that matter and prevent themselves from straying into unwanted scope. Testers can borrow statistical data or interaction/persona based information from UX that can help them shape better scope for their tests. Well, this is indeed interesting topic and deserves deep dive. I will stop here on this one for now.
A skilled tester would make this collaboration happen and would bring out the best from both the worlds.
5. Friend in need for marketing and user care
This is another area of collaboration where skilled testers can add great value to solve team's problems beyond finding bugs. I have listed some of the possibilities where testers can help user care and get benefited in return and I believe same applies to their collaboration with marketing teams:
6. Alert mechanism when system is on the verge of collapse
Well, this is bit tricky but I would mention it anyway. By nature of their work, skilled testers can use their sharp observation skills to observe and understand people, situations and events around them and can draw inferences that can help identify potential risks, before it is too late. Retrospective meeting is a great place for skilled tester to raise flags for potential issues surrounding team dynamics or people issues they observed, in constructive way of course which is where their communication skills can come handy.
Testers are usually in touch with fellow testers in organisation from where they get information around what other teams are working on, their future plans, blocking issues etc and this information can be very well used to analyse the impact on their respective team's road-map , work in progress or work items that share dependancies with other teams.
A tester who is skilled enough to foster network and relations across teams, can certainly help bypass blockages when team needs it most.
So, those are some aspects in my opinion and experience, a skilled tester can contribute value to project team beyond their traditional tasks.
If you are to a hire new tester or would like to fairly evaluate/mentor tester in your team, I would suggest give these ideas some consideration. It's high time that we look at tester as someone beyond bug finder. They can do wonders for your team and can help to accelerate shipping of quality product, if allowed to use their full potential.
