Golden Gates Paper Bridge - Group Initiative

The Golden Gates Paper Bridge Group Initiative

This group initiative is from the UNC-Charlotte's Venture Group Initiatives Manual.

I've used this initiative to discuss team work, leadership, followership, understanding the client and may other issues that arise during the debriefing.

In one training at SolutionsIQ the teams were given the requirements (build a bridge of 12" span - but when the customer acceptance was done the boat that had to pass under the bridge had towers and antenna that exceeded the specification height.  The teams had to negotiate with the Product Owner on the physical acceptance test - a toy boat passing under the bridge.

One team created their own "Unit-Test" - the box.

(Facilitator Info)

Materials:
60 sheets of paper per group, paper clips per group, approximately 60 feet of string, tape for the string, copies of rules (next page) for each group, a ruler, flip chart for debrief.

Set up:
•  Lay down string in two parallel lines 3 feet apart.
•  Count out the paper and paper clips for each subgroup.
•  Separate the practice materials: 5 sheets of paper and 5 clips.

Brief:
•    Divide group into sub-groups of approximately 5 people.
•    Hand out the instructions and read though them with group; allow clarifying questions. •    After 14 minutes, remind the group they need to choose a leader and have that person report the plan to the comptroller in one minute (as per instruction sheet). Comptroller (facilitator) informs the leaders that they have been hired by a new company (they must switch groups). Their task is to ensure that their company (the new one now) builds the best, most cost effective bridge possible. As per instructions they have 5 minutes to finalize plans.
•    After 5 minutes: it is time for construction; each group gets a space at the river. Start stopwatch.
•    When a group is done building they inform you and you tell them how much time has elapsed on the stopwatch. From that number they can calculate their costs. You need to keep track of the 1 minute the bridge needs to stay standing, as well as call out times for other groups as they finish.
•    Once all groups are finished, they should calculate their costs and profit margins. Have each group announce their profit- you then announce the winner.


Common Debrief Question Focused on Leadership:
•    It is helpful to let each subgroup do their own mini-processing with suggested questions.
•    In your small groups, please answer the following questions:
     How was the original leader chosen?
     What criteria were used?
     What effect did the new leader have on the group?
     What are the characteristics of effective leadership?
•    Come back together in large group and have sub-groups share their thoughts.

Contractor Guidelines

Your bridge-building company has been contracted to build a paper bridge over the 'river' which has been marked out in the middle of the room. The only materials you may use in this enterprise are the paper clips and scrap paper provided. You will be given a planning/ practice phase before construction begins.

The bridge must be:
•    capable of standing for 1 minute without any extra support (other than provided materials
•    at least 30 cm (12") above the river at its central point

Finances:

Your group will be paid $10,000.00 for a bridge built according to this briefing. From this you should deduct construction costs as follows:
•    $100 for every sheet of paper used (paper clips are free)
•    $2,000 for every support/stanchion which is built in the river
•    $100 for every 10 seconds (or part of 10 seconds) it takes you to build the bridge
•    Your profit is $10,000.00 minus your construction costs.

Time Frame:

     Phase I = Planning and Practice (15 minutes)
     Phase II = Group leader presents plans to comptroller
     Phase III = Final planning (5 minutes)
     Phase IV = Timed construction of bridge

Considerations:
•    During the initial planning phase you will be given only 10 sheets of paper and 5 paper clips with which to practice.
•    At the end of the initial planning phase, you must select a group leader who will present your plans (including projected costs) to the comptroller for approval.
•    You will be given a final 5 minutes planning before the construction phase begins.
•    During the construction phase each group may use up to 50 sheets of paper and up to 20 paper clips.
•    The 'river' is one meter wide
•    The group who makes the greatest profit, will be awarded the contract.

# Remember, you need to build a bridge quickly while using as little paper and as few supports as possible; and it must stand freely for one continuous minute.

A very good TED video about which groups do well in design games - like the marshmallow tower problem.

http://www.ted.com/talks/tom_wujec_build_a_tower.html

Tom Wujec presents some surprisingly deep research into the "marshmallow problem" -- a simple team-building exercise that involves dry spaghetti, one yard of tape and a marshmallow. Who can build the tallest tower with these ingredients? And why does a surprising group always beat the average?

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 …
