In our workshops and classes, participants often lament how difficult it is to get “management to do their part”. And my experience in this area has also been one of many struggles. Some managers totally get Agile and Scrum. …

A surprising exploration of scientific evidence and data from real Scrum teams to learn if size matters or not — A common belief among Agile practitioners, including myself, is that Scrum works best in smaller organizations. This belief is also often expressed by people who work in large organizations themselves, and just don’t see it work. Together with Barry Overeem, I’ve been fortunate to teach, mentor, and coach Scrum teams…

Why does Scrum so often feel like organized religion? And how can we make things better? — Have you ever noticed the many parallels between organized religion and Scrum? Or with Agile methodologies more broadly? It's been a recurring joke between Barry Overeem and me as we attend conferences, interact with critics and advocates of Scrum and follow the comings and goings in our profession. …

The role of personality, task complexity, experience, and communication skills on the effectiveness of pair programming — Pair programming is a common practice in Agile teams.

A good Pasta Napoletana requires onions, tomatoes, garlic, basil, and tagliatelle. However, its simplicity is also deceptive. The first time I made it, it was…

A sobering investigation of scientific evidence on scaling frameworks, particularly SAFe®. — How do you feel about the Scale Agility Framework (SAFe®)? I don’t know about you, but I’m skeptical of SAFe and I’m very skeptical of scaling in general. I’m not alone in this. My sense is that the professional community doesn’t like SAFe®. It is easy to find scathing opinion…

An exploration of what scientific studies and a large dataset of Scrum teams tell us about the benefits of agility — What is the business case for Agile teams? Is it really that important that they are autonomous, able to release frequently, interact closely with stakeholders and spend all that time on continuous improvement? Or is all that just hype? Or maybe even counterproductive? Yes, we believe all these things are…
