Dear Software Testing
This weekend, I saw a play that showed a manager driving out fear to lead his team to success. The play was ‘Dear England’ and dramatised Gareth Southgate’s term as manager of the England men’s soccer team. The play shows Southgate using psychology.

We need cooperation between testers and developers
Sometimes there can be competition between testers and developers. Cooperation between testers and developers is better for the company and the customer. “A system must have an aim”[1].

To copy a testing process “is to invite disaster”
Sometimes, we hear about a company that creates high-quality software. The company has great testing and quality processes, so we think about copying their ideas to improve our process. “If anyone were to study such a company without theory, i.e. without knowing what questions to ask,” they “would be tempted to copy the company”[1]. The …

Testers can help their team by using statistics, such as control charts, to do analysis. There are a lot of resources to help us use statistics, for example, this blog post …

Who is responsible for quality? Is it the tester, or the team?
I have been reading John A. Dues’ new book Win-Win W. Edwards Deming, the System of Profound Knowledge, and the Science of Improving Schools with the Deming Profound Book Club. John Dues uses an equation to describe who is responsible for student performance[1]. This equation works as a useful analogy to describe who is responsible …

It is better if we build quality into the product instead of trying to test quality in
“Cease dependence on inspection to achieve quality. Eliminate the need for inspection on a mass basis by building quality into the product in the first place.” [1] is one of W. Edwards Deming’s 14 Points for Management. Inspection can be defined as testing after development has been completed. Some people have interpreted Deming’s point as …

We need psychologically safe workplaces. Testers, and all other members of development teams, need to feel safe enough to be able to ask questions and express opinions about the project we are working on. The need for psychological safety is not a new issue. W. Edwards Deming saw it as an important issue. Drive out …

A theory of management for improvement of quality vs a quality improvement plan, which helps us more?
