The Upstream GameUnderstanding the Development Community

through Legos

What is Open Source DevelopmentWith over 3,300+ developers from 230+ different companies worldwide, OpenStack is one of the largest collaborative software-development projects. Because of its size, it is characterized by a huge diversity in social norms and technical conventions. These can significantly slow down the speed at which changes by newcomers are integrated in the OpenStack project.

What is Open Source Development

We've designed a training program to accelerate the speed at which new OpenStack developers are successful at integrating their own ideas into that of an OpenStack project.

What is Open Source Development

We have taken a slice of the two day OpenStack Upstream Training program from https://wiki.openstack.org/wiki/OpenStack_Upstream_Training and broken out the session dealing with development interaction.

Past Upstream Training

What is Open Source Development

This live class teaches students to navigate the intricacies of a project's technical teams and social interactions using Legos. It is a lot fun and very informative to the way upstream development teams, companies, and individual technical contributors behave and react to delivery dates.

Materials

● Few example Lego buildings (source projects)

● Lots of Legos○ about a 1 lb per person○ interconnects (APIs)○ base plates (community infrastructure)○ random pieces (source code)

There is not enough for everyone on purpose. Collaborate and Innovate.

Materials: Share the Critical Pieces

Roles

three major roles● 2-3 teams: upstream people (6-10 people

each) red1, red2, red3● 2-3 teams: company people (6-10 people

each) yellow1, yellow2, yellow3● individual contributors (30 people) blue

Purpose

● each team will have the same task: to expand the city block the way they want○ this will be your team’s project, whether you’re

playing the company or upstream role. ○ individual contributors will set their own purpose, for

example: decorate all in pink, cut all the trees, build something, be for hire… anything

Rules of the Game

● Select 2-3 CEOs from individual contributor group

● Upstream teams elect their own leader○ Leader will also speak for the team at the recap

● Company and Upstream pick their objective in the first planning session

● Offer them to write an Epic○ use case, objectives, features to implement

Purpose (contd.)

● purpose is not to complete the building but the collaboration in expanding the city

● each group will start with a completed building with room for expansion

● extra: plan for final result to be compatible with an another team

Facilitator's Role

facilitators are there to smooth out the process● lead the conversation● help with the planning process● discovery of how other teams were working● focus on creating communication● help participants to identify social

mechanisms that work or don’t

Before We Start

5 minutes, Design Preparation● to design your project● pick your name● write the epic on the whiteboard

Three Milestones

three cycles● 5 planning for this milestone● 20 execution● 5 review

visible countdown and audible soundkeep on the timing

Milestones 1-2

● 5 min plan, 20 min execute, 5 min review● Complete Features per milestone● Identify Bugs during review● Facilitators will help keep teams on track to

bigger issues like compatibility with existing buildings, collaboration with other teams

Feature Freeze, Milestone 3

● 5 min plan, 20 min execute, 5 min review● Last cycle should be focused on Bug fixes● Work on making Features already

implemented work

Release Review

For 5 minutes, each team speaks to● Their team name● Their objectives● Their accomplishments● What they learned
