I'm a Single Track guy

Do you believe you are more productive because you think you can multitask?  Studies show you are wrong.  Why do we believe we can; why do we think we are super-special and have powers above the average?  Answer: (pay attention) cognitive bias - attentional bias.


Media multitaskers pay mental price, Stanford study shows

People who are regularly bombarded with several streams of electronic information do not pay attention, control their memory or switch from one job to another as well as those who prefer to complete one task at a time, a group of Stanford researchers has found."





I think I will lower my personal kanban work-in-process limit to ONE.  There really is only one (Highlander - then there was the sequel).

Just last week, coaching a new team with their Scrum task board we had a conversation on the number of tasks a person could be working on at one time.  The reason given for the four tasks in process on the big visible scrum task board was that getting up from their desk to select the next task sticky was a nuisance.  The tasks were estimated at 1 - 3 hours each, and two tasks were still in process the next day.  Changing peoples perceptions of efficiency is a slow process of exposing incorrect mental models that are reinforced by cognitive bias.

Hello, wake up people, do not try to be a computer.  That day will come, as we approach the Singularity, when humans transcend biology.
In Ray Kurzweil's book The Singularity Is Near, he examines the next step in this inexorable evolutionary process: the union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our own creations.

That merging is the essence of the Singularity, an era in which our intelligence will become increasingly nonbiological and trillions of times more powerful than it is today—the dawning of a new civilization that will enable us to transcend our biological limitations and amplify our creativity. In this new world, there will be no clear distinction between human and machine, real reality and virtual reality. We will be able to assume different bodies and take on a range of personae at will. In practical terms, human aging and illness will be reversed; pollution will be stopped; world hunger and poverty will be solved. Nanotechnology will make it possible to create virtually any physical product using inexpensive information processes and will ultimately turn even death into a soluble problem.

David,

I couldn't agree more. I wrote a post on the same subject myself: Task-Switching is for Computers, not Humans @http://www.softwareresults.us/2009/11/task-switching-is-for-computers-not.html

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 …
