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.

Test Managers in Agile &#8211; Creating the Right Culture for Your SQA Team

I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.

How to increase and maintain team motivation

The best agile teams are built from people who work together as one unit, where each team member has both the technical and the personal skills to allow the team to become self-organized, cross-functional, and self-motivated. These are all big words that I hear in almost every agile project. Still, the criteria to make a fantastic agile team are practically impossible to achieve without one major factor: motivation towards a common goal.

How to Position Your Team for Success in Estimation

Estimates are critical if you want to be successful with projects. If you begin with a bad estimating approach, the project will almost certainly fail. To produce a much more promising estimate, direct each estimation-process issue toward a repeatable standard process. A smart approach reduces the degree of uncertainty. When dealing with presales phases, having the most precise estimation findings can assist you to deal with the project plan. This also helps the process to function more successfully, especially when faced with tight schedules and the danger of deviation.

Why Agile Teams Have to Understand How to Analyze and Make adjustments

How do we acquire knowledge? This is one of the seemingly basic but critical questions you and your team members must ask and consider. We are experts; therefore, we understand why we study and what we should learn. However, many of us do not give enough thought to how we learn.
