I have chosen this topic for today to help individuals to understand in a better way the differences and similarities between the software development methods:

• Waterfall (traditional);
• First Generation of Agile (XP, Scrum);
• and Second Generation of Agile (Lean, Kanban, BDD).

    The goal of this article is to hear readers' opinions, knowledge and thoughts on this topic. And, most of all, to hear the best practices from people who use at least one of the methodologies in Agile Software Development.

    We know that DevOps is a culture, a subset in Agile, where developers, other IT professionals and QA team work together, to build the product/service. This DevOps means actually an increased level of communication and collaboration between these people. What about BDD?

    It seems that people and organizations embracing Agile have reached the critical mass. A few studies on this topic revealed that actually developers are the ones embracing Agile. The executives are tougher to be convinced by the benefits and to make this move towards Agile, despite its spread beyond software development.

    According to Wikipedia, "User acceptance testing (UAT) consists of a process of verifying that a solution works for the user.". Why is it important? Because lots of things can happen without UAT.
