Each year, Ministry of Testing launch a #30DaysOfTesting challenge. This year the topic is ‘Quality‘. The challenge began in March, but I was a little late getting started. So, throughout April and May, I’m going to be publishing a series of blog posts where I share my progress.

Day 9 – Contribute to a discussion on The Club about ‘Quality’

There is a lot of discussion around ‘What Quality Is?’ but few people seem to be asking, “Who Decides Quality?”

The following quote is often used when defining quality:

“Quality is value to some person (who matters, at some point in time)”

Jerry Weinberg (with additions by James Bach and Michael Boltons)

I was especially interested in learning who that person might be and why they matter. To answer this question, I decided to create my own discussion. This was posted on The Club and LinkedIn.

There needs to be a clear direction for quality, and this doesn’t usually come from a software tester or a QA (Quality Assurance). It could be argued that QA’s don’t actually take part in ‘assuring quality’. However I believe we do to some extent. We assure that the application meets a specified level of quality – but we don’t decide what that level of quality should be.

Who decides quality? Is it a single person? Is it multiple people?

It won’t be the user. The application will be based on what the user wants or needs, but the user will rarely be the one making the decisions. These are made by someone within the business.

For Day 4 of the 30 Days of Quality challenge, I analyzed different perspectives of quality from the point of view of other members of the team. This demonstrated that impacts and risks varied depending on their job role.

Involving too many people in the discussion could lead to conflicts about what the priorities should be. However, the subjective nature of quality indicates the need to gather information from as many teams as possible. The end-user may only see the application in its entirety, but its made up of many smaller components – each one of these is essential.

We should finding out what the perceived risks are from all stakeholders. Do we hold the priorities of some stakeholders higher than others? That depends on the priorities of the business, which are not likely to be fixed.

One thing that everyone can agree on is that there must be a clear direction for quality. Everyone needs to know what is important and what the business goals are. Without understanding this, we will not be able to contribute efficiently the applications overall quality.


One thing this task changed about my own perception of quality was that there is an overall perception of quality, and all the individual components that contribute to that perception. If a single one of those components breaks, then the quality of the application will take a dramatic dip. Therefore quality cannot be attributed to a single person or team.

We should contribute to improving the quality of each component, as this in turn will improve the quality of the entire application.
