Do you possess the necessary characteristics to adopt an Agile testing mindset?

To understand the agile testing mindset, we first need to determine what makes a team “agile.” To me, an agile team continually focuses on becoming self-organized and cross-functional to be able to complete any challenge they may face during a project.

QA Management – Tips for leading Global teams

The events over the past few years have allowed the world to break the barriers of traditional ways of working. This has led to the emergence of a huge adoption of remote working and companies diversifying their workforce to a global reach. Even prior to this many organizations had already had operations and teams geographically dispersed.

Putting Together a Testing Team

As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.

Assessing Risks in the Scrum Framework

Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).

Fluent Interface Design Pattern in Automation Testing

Recently, I was going through some of the design patterns in Java by reading the book Head First Design Patterns by Eric Freeman, Elisabeth Robson, Bert Bates, and Kathy Sierra.
