Coaching is a term that is now being mentioned a lot more in the leadership space. Having grown successful teams I thought that I was well acquainted with this subject.
The key to successful test automation is to focus on tasks that maximize the return on investment (ROI), ensuring that you are automating the right tests and automating them in the right way. This is where test automation strategies come into play.
Agile software development stems from a philosophy that being agile means creating and responding to change swiftly. Agile means having the ability to adapt and respond to change without dissolving into chaos. Being Agile involves teamwork built on diverse capabilities, skills, and talents. Team members include both the business and software development sides working together to produce working software that meets or exceeds customer expectations continuously.
Ever since the Internet was invented, web developers have searched for the most efficient ways to display content on web browsers.
