The Product Owner in Scrum is accountable for the value delivered. Besides the fact that value is a very different driver than volume is (think outcome versus output), that accountability can hardly be demonstrated without a clearly identified ‘product’. Product is the vehicle to deliver value. Neither can a Product Owner be accountable and effective without a mandate to make decisions. Product Owner accountability cannot be mapped on existing roles or functions, nor can it be effectively enacted through deliverables and meetings dating from the industrial age.

Although ‘product’ determines the scope, span, and depth of Scrum, it is one…

Scrum has been around for a while, they say. The Scrum Guide holds the definition of Scrum, they say. The first, official version of the Scrum Guide was released in February 2010. So, how was Scrum defined before 2010 then? How did its definition evolve before and after 2010 and become the framework that we know today? What else happened along the road to the way that Scrum is defined and represented?

In the paper “Scrum: A Brief History of a Long-Lived Hype” I have described what changed to the definition and representation of Scrum over time, before and after…

“Life isn’t about finding yourself. Life is about creating yourself.”

(generally attributed to George Bernard Shaw)

I call myself an independent Scrum Caretaker. It reflects who I am, how I feel, what I do: caring for Scrum AND caring for people. It is my identity in the sense that it defines me professionally in my relationship to the world.

I call myself an independent Scrum Caretaker on a journey of humanizing the workplace with Scrum. That reflects what drives me. It is my personal why. It is also an infinite game. …

Scrum turns 25 in October 2020. Hip hip hooray!

It is a good opportunity to share a few highlights from the past 17 years of my life as an independent Scrum Caretaker — of “My life of Scrum” (since 2003).

September 2003. The founding managers of our company ask me to have a look at the challenge of delivering the (Java-based) core server platform for a large digital television implementation (one of the first in Europe at a bigger scale). Due to longer negotiations and delayed sign-offs, the project is already late before the real work has even started…


Six Essential Traits of the Game

Apparently, it is easy to get stuck at interpreting the rules of Scrum. In the publication “Moving Your Scrum Downfield” (available as a free PDF) I have described the six essential traits of the game to help you get unstuck and up your game. As they express rather intrinsic and implicit principles, they are too often disregarded. Yet, they are needed for a more unconsidered performance of Scrum, which allows minding the goal of the game-push back the old adversary of predictive rigidity-rather than the rules. These six essential traits are indicative of Scrum coming to life.

Ever since the accidental creation of my book “Scrum — A Pocket Guide” in 2013, and its deliberate evolution in 2019, I’ve been receiving inquiries about an audiobook version. So far, I have not been able to make that happen but the 2020 pandemic storm got me into implementing the audio idea in a different form.

In five subsequent daily broadcasts I have read all chapters from my pocket guide to Scrum.

In Episode 1 (49:07) I have read: Foreword by Ken Schwaber Preface 1. THE AGILE PARADIGM 1.1 To shift or not to shift 1.2 The origins of Agile…

Ever since the accidental creation of my book Scrum — A Pocket Guide (A Smart Travel Companion) in 2013, and its deliberate evolution in 2019, I frequently receive inquiries about the availability of an audiobook version.

Although I see value in the idea, I have not been able to make it happen so far.

Given the current pandemic storm, forcing many friends of Scrum to remain at home, I decided to implement upon the audio idea in a slightly adjusted form.

Starting Tuesday 24 March 2020, I have planned a first series of five “ Daily Scrum Pocketcasts.” In subsequent…


Perspectives of an independent Scrum Caretaker on a mision to humanize the workplace

The United Nations’ World Health Organization (“WHO”) correctly describes “Covid-19” as the disease caused by the “SARS-CoV-2” virus, a new variant within the Corona family of viruses. A Covid-19 infection typically shows through symptoms of fever combined with respiratory problems — a dry cough, shortness of breath, and (severe) breathing difficulties. As we speak, Covid-19 is exponentially spreading across large parts of the world, infecting frightening numbers of individuals. Although “Corona” actually is the name of the family of viruses, references to the current pandemic outbreak typically are “Corona (something).”

Beyond anything else, my thoughts are in the first place…


There is more to Scrum than a set of rules. The rules of Scrum and their underlying principles are complemented by the Scrum Values.

With Scrum, a framework is created upon which people and organizations develop a working process that is specific and appropriate to their time and context. The rules and principles of Scrum all serve empiricism, or empirical process control, offering closed-loop feedback control, as most optimal for dealing with complex challenges in complex circumstances.

There is however more than the rules and the principles. Scrum is more about behavior than it is about process. The framework of…


(that will help you optimize your Scrum)

Scrum, in its more general definition, is a simple framework to help us address complex challenges. Product development is the subset of complex problem domains where Scrum took root first; by explicitly acknowledging software and new product development to be complex work, serving to deliver complex products in complex circumstances.

Scrum is increasingly being discovered as a simple framework to address complex problems and situations other than software and product development. More and different people, teams and organizations ask for guidance and support on their journey of Scrum, no matter the nature of their problem. Organizations discover that fighting complexity…
