Groupthink in Scrum Teams


How do you combat this known dysfunction of a group in Scrum teams?

Groupthink is defined best I think by Irving Janis, who studied it's effects in the Bay of Pigs invasion, the attack on Pearl Harbor, and the escalation of the Vietnam War.

Groupthink - A mode of thinking that people engage in when they are deeply involved in a cohesive in-group, when the members' strivings for unanimity override their motivation to realistically appraise alternative courses of action.
- Irving Janis. Victims of Groupthink. 1972, p. 9.
President Kennedy's thigh-knit group got caught up in groupthink, but learned their lesson and changed their group-decision making process by the time they dealt with the Cuban missile crises. A small proof of a learning organization.

Did President Bush's group learn there groupthink lessons?

Janis gives 8 indicators of groupthink:
  • Invulnerability - many members of the ingroup have an illusion of invulnerability.
  • Rationale - they rationalize away warnings and other negative feedback.
  • Morality - they have a belief in inherent morality on their side.
  • Stereotypes - they hold stereotyped views of opposing groups leadership.
  • Pressure - they apply direct pressure to any dissenting individual.
  • Self-censorship - they avoid deviating from group consensus.
  • Unanimity - they share an illusion of unanimity.
  • Mindguards - they appoint themselves as guards to protect the leader from adverse information.
Janis has some recommendation on the remedies for groupthink:

  • assign the role of critical evaluator to each member & reinforced by leader's actions
  • leaders should adopt an impartial stance at beginning
  • set-based design; separate groups working the same issue
  • require members to discuss with their associates
  • outside experts invited to challenge the views
  • assign a devil's advocate for general evaluations
  • devote a sizable block of time to rival orgs. responses & warning signals
  • subdivide the group to work under different chairpersons
  • hold a second-chance meeting - encourage doubts to be rasied
Janis warns of the disadvantages that these remedies may bring about, i.e. prolonged debates, rejection, anger, power struggles, etc. However the history tells us that we make big, HUGE mistakes (like looking for WMD in the sand) when we allow ourselves the luxury of groupthink. So putting in place a few checks and balances would be very prudent - don't you think?

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…

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.


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 b…

Timeline of Social Networks -or- the Long Haul

I was listening to KERA's Think and they mentioned the concept of social networks.  It got me think...

But the book Long Haul, is its own interesting story - A Million Miles and Counting - A Trucker's Tale.

“The Long Haul: A Trucker’s Tales of Life on the Road”
Did you know 41 million people move in the US a year?  Having moved a few times in my life, sometime with the Bed-Bugger's help, this book is a great insight into that life.
Author: Finn Murphy's CB handle - "U-Turn" The radio interview noted the concept of social networks in the 21st century.  What is a highway - but a manifestation of a social network - a trail across the land.

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…

One Dark and Stormy during a Hurricane

I'm from the Carolina's where legend has it that our family commonly just hunkered down in the home on the coast and waterways than to head for inland shelter. Now that's from the old school days of barely improved (read paved) roads. They counted a storms severity by how high on the back porch steps (about 15 - top to ground) the water reached.  I don't recommend this action in todays world of long range forecast and transportation options.

I do recommend a drink or two in a hotel bar, far far away.

This is the week that Harvey came ashore in Texas.  I live on a hill in the little old town of Grapevine outside Dallas and Fort Worth.  And thank you all for letting me know that a storm is coming... I didn't get out and walk Malibu before the rain hit, so I grabbed a hat and we went anyway.  Much nicer walk with the drizzle, I'd say.

I'll raise a glass to you - if you were not smart enough to do the responsible thing, at the last responsible moment.

I do re…
