What does it mean to be Human Scaled?

When I think about the size of something I think in a frame of reference of a human being. Yeah, sounds funny, but I can think in other frames of reference but it is a weird trick I have to play in my mind to do that. Like switching the foreground and background in one of those pictures of the old and young ladies.

So what is the Human Scale? What's the smallest a person can typically see, something we see and really have a sense of the size of it? A grain of salt is about the smallest. That's about one-half mil-meter (10^-4 X 5m). And the largest, I say something like an oak tree 20 meters (10^1 X 2m).

Can I really get a sense of a Redwood Tree at 110 meters (10^2 X 1.1m) or the Eiffel Tower at 320 meters (10^2 X 3.2m)? I've been to Paris and standing near the tower there is no sense of how large it really is. Only from many blocks away do you feel like you can take it all in, but then you have only a vague idea of what makes the tower, the steel and bolts.

But how big is the solar system, and what's the size of our galaxy? Or what is the size of a electron shell in the carbon atom?

Well, I've found that there is a word for this 'human scale of perception' in this wonderful mind expanding TED talk by David Eagleman. The word is "umwelt" - the German word for the surrounding world.

Can we create new senses for humans?
Watch Eagleman's TED talk for a chance to expand your personal umwelt.  Technology will and does expand our umwelt - there are many people with low tech augmentations, eye glasses, hearing aids, walking canes; and these augmentations are getting much higher-tech... and the mind is very plastic and will accept many types of data - we just need to plug it in (PH model of Evolution).  Sensory substation has been happening since 1969.  Is the vibration of the cell phone in your pocket just a very simple signal of feeling the umwelt that someone is wanting your attention.  Would you like to expand this capability?

Here are two wonderful visualizations that help us change our human frame of reference and feel like we can imagine outside our small human scale of only 5 orders of magnitude.

Scale of Universe an interactive tool (flash)

"Powers of Ten takes us on an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only as a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker - with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell."

Assume the 1 stands for one meter... what's the human scale?

Helen Czerski encourages us to play with toys to understand the physics in the middle (human scaled).

Physics doesn't just happen in a fancy lab -- it happens when you push a piece of buttered toast off the table or drop a couple of raisins in a fizzy drink or watch a coffee spill dry. Become a more interesting dinner guest as physicist Helen Czerski presents various concepts in physics you can become familiar with using everyday things found in your kitchen.

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: 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, …

Elements of an Effective Scrum Task Board

What are the individual elements that make a Scrum task board effective for the team and the leadership of the team?  There are a few basic elements that are quite obvious when you have seen a few good Scrum boards... but there are some other elements that appear to elude even the most servant of leaders of Scrum teams.

In general I'm referring to a physical Scrum board.  Although software applications will replicated may of the elements of a good Scrum board there will be affordances that are not easily replicated.  And software applications offer features not easily implemented in the physical domain also.

Webinar: Collaboration at Scale: Defining Done, Ready, and NO.

I was invited to participate in a Scrum Alliance Webinar.  Maybe you would like to listen to us in a discussion of techniques to collaborate at scale (remotely and with many people).  The topic is one that I've got some experience in discussions - yet I never seem to get to done...
Collaboration at Scale: Defining Done and Ready and NO for Distributed Teams
With Joel Bancroft-Connors, Agile Organizational Coach; David A. Koontz, Agile Transition Guide; and Luke Hohmann, CEO and Founder of Conteneo, Inc.

14 February 2018 11 a.m. ET (USA).

The Scrum Guide is pretty clear on the criticality of the definition of Done: "When a Product Backlog item or an Increment is described as "Done," everyone must understand what "Done" means. However, the Scrum Guide ALSO says that the definition of Done can "vary significantly per Scrum Team." This leads us to examine when and how the definition of Done should vary, how distributed teams should cr…

A T-Shaped 21st Century Knowledge Worker

Knowledge workers in the 21st Century must have many areas of deep knowledge, while also be capable of collaboration across multiple other domains with dissimilar T-shaped individuals.  This description of a person is a metaphor.  Compare it to the shape of the "I" in the classic saying there is no "I" in Team.

I first read about Scott Ambler's term "Generalizing Specialist" - but it's so hard to remember the proper order of the words... get it backwards and it has an inverted meaning... T-Shaped is easier to remember. 
A generalizing specialist is someone who:
Has one or more technical specialties (e.g. Java programming, Project Management, Database Administration, ...). Has at least a general knowledge of software development. Has at least a general knowledge of the business domain in which they work. Actively seeks to gain new skills in both their existing specialties as well as in other areas, including both technical and domain areas.  General…

A FAILURE to Communicate

I was working with a failing team some time ago.  I use "failing" to describe the outcome of the team - not the people on the team.  Are you OK with that description?

An issue arrose in the stand up - a team member that was to verify the quality of a procedure did so and reported that there were a few records that didn't match expectation in the data set.  Upon inquire the number of records not matching was over 2000.  Most people acknowledged immediately the exaggeration - I could tell by the laughter.  After about 10 minutes of discussing the details of the problem - it appeared the team had a handle on the specific situation.

I stopped the discussion and inquired if they could name the impediment.  One team member did a great job of describing the impediment as a _communication gap_.  Wonderful - I could work with that - the problem had a name and it didn't include anyones Proper Name.

"If the problem has a first name; we are going to have a problem."
