How to move away from the In Test column
We as testers are always looking at ways to improve our testing processes and one way to do that is to move away from the In Test column. You can read more about the why in my post “In Test” column but the how I left pretty vague. I’d like to outline one way in which you could but just like removing the in test column it may seem counterintuitive; by adding even more columns.
How does adding more columns help? Well let me walk you though the process and all will become clear…
Breaking down the In Test column
“What did we actually test?”
One of the first things you’re going to need to do is break down what you do in the “In Test” column. Now this might not be as easy as it sounds but one of the best ways to do this is try to answer the question “What did we test the last time a ticket went through the in test column?” You want to think about all the different activities you carried out for the last few tickets. One way to do this is get some sticky notes and on each one write down the specific type of testing you did e.g. retested defect No. 5487 or pair tested new feature X etc. Then group them up under headings that make sense such as: regression testing, accessibility testing, performance testing, smoke testing, feature testing, automated UI testing , etc. This is best done as a group with people who are familiar with the testing process as they will keep you honest with what you do and don’t do during testing.
These sub-heading are going to become your new columns that come under the banner of Testing.
Now for each sub-heading you want to create entry and exit criteria for when a ticket can be placed into that column. So for instance what entry criteria does a ticket need to begin Accessibility testing e.g. there needs to a UI element to the ticket. What criteria would that ticket need to satisfy so it can leave (exit) the column? E.g. feature run against accessibility guidelines, any issues not fixed have been communicated to accessibility team/product owner etc
So you’ve got all these extra columns now what?
Well, you could just leave it at that and simply making the work more visible the team has a better understanding of what work we as testers actually do. Or you can start to use it as a tool on where to focus your Test improvement process.
Test improvement process
By making all the different testing activities visible you get other benefits too:
- Makes testing work explicit instead of being hidden under the banner of “Testing”
- Entry/Exit criteria helps the team understand why that testing needs to happen
- And when it’s complete
- Length of time a ticket spends in the columns start to make bottlenecks (constraints) visible
By recording how long a ticket spends in each of the columns you can start to see which of the activities is taking the longest.
This will identify the most valuable candidate to start your improvement process. Anything before or after the bottleneck is not going to make as greater impact because the biggest issue isn’t being addressed.
Once you’ve identified your bottleneck you can as a team look at the entry/exit criteria as a starting point for improvements. You could look to see if the risks this type of testing is mitigating against can be address in some other way. For example earlier on in the process or rather than manually in some automated fashion but remember the automation fallacy.
Eventually you will find that the bottleneck “moves” to another part of the testing process which is your next candidate to carry out your improvement process. If you keep going you will start to see that tickets spend less and less time in the identified columns. In some cases you will see that the columns isn’t even need anymore and can be removed all together.
This is known as the 5 focusing steps from the Theory of Constraints. You can find more on Wikipedia and elsewhere but these are:
- Identify the system’s constraint(s)
We do this by measuring how long each tickets spends in the columns and work out which testing task is taking the longest.
- Decide how to exploit the system’s constraint(s)
By looking at the entry and exit criteria and seeing what could be improved as a team.
- Subordinate everything else to the above decision(s)
Once your improvement process has been identified assign it as a task for someone to carry out or if possible as a team work on it together (swarm).
- Alleviate the system’s constraint(s)
Carry out the mitigation methods identified above, update the entry/exit criteria for the column and keep measuring how long the ticket stays in the column going forward.
- If in the previous steps a constraint has been broken, go back to step 1, but do not allow inertia to cause a system’s constraint
If the mitigation method(s) alleviate the bottleneck start the process over BUT don’t stop, keep going till you’ve address all the different types of testing.
Eventually you will be left with some testing that cannot be mitigated but the entry and exit criteria will indicate exactly what testing needs to happen (column heading), why you need to do it (entry criteria) and when its done (exit criteria).
You can then simply make this a part of something that happens for a ticket and you should be left with just the “In Progress” column.
Remember this strategy doesn’t just work for improving testing but all activities that a team carries out. You just need a way to identify the activities and make them visible.
