Software Development terms applied to Home Construction

Let's Invert the typically wrong headed view of Software Development project management as a construction project.  We can map it the other way just to see if it works... to have some fun, to explore the meaning of phrases we toss around quite frequently.

Site Landing Page

Normally Project Management terms come from a construction domain.  We are going to apply the lexicon of modern software to the construction of a home.  We will follow the construction project and meet some of the people doing the work.

This is a very small (8 homes from $600,000 skyward) program in my 30-40 year old neighborhood.

About 6 months ago I saw the programs landing page go up.  It gives casual observers and some of the stakeholders a general idea of the intent of the program.  And most importantly who to contact for additional information if you happen to be interested in their products.

The Refuge program has 8 product projects and has them running independently.  Yet much of their DevOps infrastructure has already been created, connected into the internet grid and stubbed out on-site.

They have spent around a year getting this very basic architectural infrastructure stack created and connected.  It is some of the most expensive work; with lots of planning and sign-off, all unseen to the interested stakeholder.

a Walking Skeleton
So today at the end of August, 2017, the program has 3 projects underway and starting to add value.  The walking skeleton of the 908 Vintner project is looking great.  Let's examine a few of the product's features and the engineers creating them.  Looking closely at the temporary construction and test framework on the right of the skeleton we see two engineers placing shaved pixels precisely onto the 2nd floor dormer feature's facade.  Pixel placement and facade construction is a tedious process in this project.  But the external facade is in the 80% complete phase.

Here is Joey, one of the specialist
(and generalist - very T-shaped engineer) is doing very precise pixel placement for the back-porch feature.

Interface for Fireplace Feature
We also see some of the interfaces have been hung for the sub-feature referred to generally as the back-porch fireplace.  If you zoom in and examine some of the facade's pixels you might find that their CSS techniques are very old school.  This group of engineers are actually utilizing one very high powered pixel-slicers, to make the component edges look very mitered and give that classic red brick look and feel.

 project infrastructure
Now let's inspect the status of one of the other projects not so far along.  Here we see a plumbing ditch that the DevOps people have requested be installed before the foundation is even laid.  This is site work, and if it is not within spec then major replanning or rework will be required in the project.

We also see on the just barely started project a set of stubbed out services in place on site.  These stubs are functional and highly regulated stubs that are used to boot-strap the projects builds.
Services Stubbed out.

 Next time we will take a look at some of the more functional interior features of the projects.

The Next Project

ground work
As the 2nd project on the program get's underway we see lots of the ground work needing to be done.  It require moving lots of dirt.  Now I question if a home foundation can be laid upon 3 feet of fill dirt.  but I see that the slab is going to have lots of steal and stressing compression cables.

After many of the project's services are located they are stubbed out.  Left here for some future engineer to connect to a functional appliance.  In this industry there is a lot of phased development with interfaces stubbed out.

port holes in firewall
Here's a look at the ground work with a firewall barrier in place.  Looks like they are taking extra precautions at the holes in the firewall.

firewall inspection
Malibu my golden retrieve, is inspecting the firewall, and steal reinforcement for the foundation.  [do we have a term in software for rebar or prestressed concrete components?]

Garbage Collection
But here's a situation I know we could help them... Garbage Collection.  OMG they don't play the game of cleaning up after yourself.  They create lots of trash piles and just expect someone else to come along and pick it up.  They do not recycle their bytes.  The system cost of this portions of the project would be a Lean Waste bonanza.

Initial Data Load

Data Normalized

I've been waiting for this day - the initial data dump.  Here we see a crew (some generalist and a few specialist) working together to insure the initial data in the Foundation is spread out evenly across the various hard drives of the RAID system and doesn't interfere with the stubbed out interface already located.

And just a day later all the data process scripts have normalized the initial data load.

Next someone laid out the plan onto the physical data layer in chalk.  Then I saw a designer of truss systems taking physical measurements (not using the plan).

Wood data dump
Blue firewall/adaptor
A few days later (I think it may take days for the foundation's data to harden) there's a new crew out doing another data dump (but a new type of raw data - this data type is handled very differently than the previous data).  The very next day engineers are hard at work crafting frameworks for features common to all homes.  They build these frameworks from raw data of a base object Wood.  There will be lots of wood put into this project, and that wood base object will have many customizations, extensions, and specializations applied.  The wood and concrete interface will also be treated with a special interface firewall adaptor.  I'm not sure if this is a water firewall or an insect firewall - it may be a new air firewall component.

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.


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…

Innovation in the Automobile Industry

In the 1900s the automobile industry was the most important and innovation industry in the USA.  But one could question if this was good for our society in the long run.  And one could question if they actually innovated.

In the early 1900s there were few automobiles, very little infrastructure created to support the industry.  For example the road system was still designed for horse drawn wagons and the wagon wheel (remember a steal rim and wooden compression spoke wheel).  The future US Highways, or the 1950s Interstate Highway System at the cost of $425 billion were decades and many innovations away. There was no gas service station, there were however horse stables, farriers, and blacksmiths in each town along the roads.  There was no real "road map", there was no road naming system, like was created in 1926 - the United States Numbered Highway System.

The industry employees millions of people, and was a large factor in the economy of the USA.  It created or was created b…

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.

Where is Shakespeare When We Need Him?

We are desperately searching for a term for people that connotes the best of human kind.  The creative, sensing, combinatorial synergistic, empathic solutioning persons that have yet to been labeled with a role name that works.

Some of the old terms:
Staff, Workforce, Human Resource, My Team, Army, Company

Shakespeare created 1700 words in his time.  He mutated verbs to nouns, and vice-a-versa, transformed verbs into adjectives, and formed words from whole cloth never before heard.  This skill is rare, but there is a poet that can create the term we need in the twenty-first century.

What should this term define?

21st Century Human Resource; the generalizing specialist.

Yes, but what more?  What less?

Suggest your poetry in the comments, let us see if we cannot do 1/1700 as well as The Bard.

By-the-way; who create the phrase "coin a word"?
