Yes - You Need a Full Time Scrum Master


Many organizations adopting Scrum ask these questions.

  • Do we need a full time Scrum master for each team?
  • Why do we need a full time Scrum master, can't they do other roles also?

Now allow me to give you the answers: 
  • Yes, you need a full time Scrum Master.
  • Why - watch the video.
Let me explain:

Yes, you need a full time Scrum master, because they will be constantly watching for the actions of the team.  Making sure that the team member are working in flow as often as possible.  This is a full time job.

Why can the scrum master not do other roles on the team? Because of the human ability of selective attention.  First let me show you a video - a little test of your superior ability to follow instructions.  Perhaps you've seen this video - if so, just play along, maybe you will be surprised at how well you do on the test.

The Monkey Business Illusion

Now do you understand why we need a Scrum master watchhttp://www.infoq.com/articles/case-dedicated-scrum-mastering out for impediments all the time.  If they are tasked with doing something else, I'm sure they will miss the obvious impediments the subtle changes in the team members and the environment.

Here is Jeff Sutherland's reasoning (from Scrum Development Yahoo group):
"One of the leading Agile teams in software development asked me how to go hyperproductive. I was their coach as my venture group had invested in them. They had a fuzzy ScrumMaster definition and it was not clear who owned this role. I told them to get a ScrumMaster. The experienced team thought they were better than that and could never go hyperproductive. A new team was formed with a ScrumMaster which immediately went hyperproductive."

"So a lot of teams that think they don't need a ScrumMaster are a long way from 10 times the performance of a waterfall team. This was the design goal for Scrum and every team should be getting a 10% velocity increase sprint to sprint until they hit that number."

"Teams without ScrumMaster's don't do this. Usually they are flatlined and will never reach their full potential."

Exercise:: Definition of Ready & Done

Assuming you are on a Scrum/Agile software development team, then one of the first 'working agreements' you have created with your team is a 'Definition of Done' - right?



Oh - you don't have a definition of what aspects a user story that is done will exhibit. Well then, you need to create a list of attributes of a done story. One way to do this would be to Google 'definition of done' ... here let me do that for you: http://tinyurl.com/3br9o6n. Then you could just use someone else's definition - there DONE!

But that would be cheating -- right? It is not the artifact - the list of done criteria, that is important for your team - it is the act of doing it for themselves, it is that shared understanding of having a debate over some of the gray areas that create a true working agreement. If some of the team believes that a story being done means that there can be no bugs found in the code - but some believe that there can be some minor issues - well, then yo…

Do You Put “CSM” After Your Name?

I’ve noticed a new trend—people have been gaining titles. When I was younger, only doctors had initials (like MD) after their names. I always figured that was because society held doctors, and sometime priests (OFM) in such high regard that we wanted to point out their higher learning. I hope it was to encourage others to apply themselves in school and become doctors also. Could it have been boastful?

The Wikipedia describes these “post-nominal initials”:
Post-nominal letters, also called post-nominal initials, are letters placed after the name of a person to indicate that the individual holds a position, educational degree, accreditation, office, or honor. An individual may use several different sets of post-nominal letters. The order in which these are listed after a name is based on the order of precedence and category of the order. That’s good enough for me.
So I ask you: is the use of CSM or CSP an appropriate use of post-nominal initials?
If your not an agilista, you may wonder …

David's notes on "Drive"

- "The Surprising Truth about what Motivates Us" by Dan Pink.

Amazon book order
What I notice first and really like is the subtle implication in the shadow of the "i" in Drive is a person taking one step in a running motion.  This brings to mind the old saying - "there is no I in TEAM".  There is however a ME in TEAM, and there is an I in DRIVE.  And when one talks about motivating a team or an individual - it all starts with - what's in it for me.

Introduction

Pink starts with an early experiment with monkeys on problem solving.  Seems the monkeys were much better problem solver's than the scientist thought they should be.  This 1949 experiment is explained as the early understanding of motivation.  At the time there were two main drivers of motivation:  biological & external influences.  Harry F. Harlow defines the third drive in a novel theory:  "The performance of the task provided intrinsic reward" (p 3).  This is Dan Pink's M…

Situational Leadership II Model & Theory

Have you ever been in a situation where you thought the technique needed to move forward was one thing, yet the person leading (your leader) assumed something else was what was needed?  Did you feel misaligned, unheard, marginalized?  Would you believe that 54% of all leaders only use ONE style of leadership - regardless of the situation?  Does that one style of leading work well for the many levels of development we see on a team?

Perhaps your team should investigate one of the most widely used leadership models in the world ("used to train over 5 million managers in the world’s most respected organizations").  And it's not just for the leaders.  The training is most effective when everyone receives the training and uses the model.  The use of a ubiquitous language on your team is a collaboration accelerator.  When everyone is using the same mental model, speaking the same vernacular hours of frustration and discussion may be curtailed, and alignment achieved, outcomes …
