Building Behavior Driven Teams - PHPCon Poland 2014

Many teams in their development process tend to focus on answering the question “how” instead of “why”. This leads to many misunderstandings which in turn decrease productivity and pleasure of working.
In my presentation I waned to introduce Behavior Driven Development which is one of the ways to improve communication within a team. I will share my knowledge on how to start with BDD in your company and say a couple of words about things like StoryBDD, SpecBDD and living documentation. Taking my team as a use case I will also speak about how BDD helped us in understanding each other and making software that matters.
