Building Better Software. Building Software Better. ACE! is the largest regional conference of its kind in Central Europe, attracting people from all over the region. We're really excited about ACE! 2015 which combines two one-track conferences into one. The Building Software Better track includes the traditional ACE! content such as agile, lean, Scrum, Kanban, and other processes and methods for improving the software development process. But this year we're adding a Building Better Software track that features Lean Startup, LeanUX, Design Thinking, and Customer Development topics. We're also adding a workshop track so that attendees can apply new skills and experiment with new ideas. It's going to be the best ACE! yet! ACE! brings together some of the best-known agile and lean practitioners in Europe and abroad, so you're sure to have a great networking experience and come away with new ideas and enthusiasm.
