Agile in Distributed Development – A Formula for Success

Agile has unquestionable benefits. The mainstream method has assisted numerous businesses in increasing organizational flexibility as a result, developing better, more intuitive software. Distributed development is also an important strategy for software companies. It gives access to global talent, the use of offshore outsourcing to reduce operating costs, and round-the-clock development.

Three Techniques for Improved Communication and Testing

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.

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.
