scaled lego4scrum - done with 155 people!

Recently I had a chance to run lego4scrum for ... 155 people. And it was fun!

The simulation started with explaining the ideas of the LeSS and LeSS Huge frameworks.


Then we run a team self-design workshop where all participants create 22 teams based on their skills and some other constraints.


Six product managers played a Product Owner team with a Chief Product Owner in charge of the overall product visioning and alignment.


This was a Lego Enterprise with a mission of providing long-distance sightseeing trips to city citizens. The enterprise received its initial funding and was expected to get profitable as soon as possible.


Based on presented market needs (users were willing to travel and pay for certain destinations) the Product was split into six Requirements Areas (one for each of the cities) each with an Area Product Owner and 3-6 teams to work on a specific city with its infrastructure.


Then all Requirement Area groups had a simultaneous Initial Product Backlog Refinement session for about 15 minutes defining product elements to get built. This process was facilitated by a pair of ScrumMasters serving each group.


Surprisingly a community of practice emerged during these discussions - representatives of different groups started to design a transportation hub with a goal to minimize the needed material (the materials had to be bought and were expensive).


Then a multi-team Sprint Planning for 22 teams all in our room. Just 3 minutes. All teams created their Sprint Backlog and also a visual Sprint Board to visualize sprint progress...


The Enterprise nearly broke after the 1st sprint - too much material spent on cities (Lego bricks had its price) and very little buses and roads to actually help making money (Oops!).


After a series of retrospectives: one per a Requirement Area and then an Overall one, the Enterprise agreed on its key improvements.


Surprisingly, the market changed too. Right after "Brexit" everyone was willing to leave London, and also due to the Christmas time Prague became the number-one destination. This came to a big surprise to the teams and the Product Onwers since Prague was not in a list of the six initial cities... Inspect and adapt!


The 2nd sprint demonstrated the whole power of self-organization and unleashed creativity. The teams were able to demonstrate 6 cities interconnected with transportation lines cruising passengers and they made good profit!

The upcoming new book "lego4scrum 3.0" is going to have the scaling approach defined in greater details.


It will also include key improvements made to the game since 2011, namely:

  • using user story mapping
  • running multi-team backlog refinement sessions
  • introducing the role of a customer and a market
  • using ideas from LeSS to get it scaled

Stay tuned!

    I had also tried a "scaled" variant with 6 teams. The common mission was to create a Town with each team having a "Ministry" like: 1. Health and Sanitation, 2. Education 3. Law and Order 4. Transportation 5. Water and Electricity 6. Finance.

    Each ministry would have their own backlog, reviewed by the "Minister" or the PO, and all Ministries had to resolve the dependencies among them.

    Having done my variant, I am very interested in reading more about the Lego Enterprise and hopefully use it in one of my upcoming sessions.

    I also played the Lego game with 100 persons on the 16th of November. It works great.
    I would like to know more about how you did the LESS game.

    Will you make a sort of document about it?

    The market distorted as well. Directly after everyone was eager to go away London, and also because of the Christmas time Prague turned into the main goal.
