Hands-on practice: two ways to run a project
The document discusses the Ball-Point Game, a simulation designed to illustrate different project running approaches, specifically plan-driven and change-driven methods. It details rules and setups for both approaches, including iterations, team dynamics, and retrospectives aimed at analyzing lessons learned. The purpose of the game is to facilitate understanding of team collaboration and production processes under varying conditions.
Hands-on practice: two ways to run a project
- 1. Hands-on practice: two waysto run a project The Ball-Point Game Reloaded
- 3. The Ball-Point Game Facts: ○game author is Boris Bloger ○ introduced at Spring Scrum Gathering 2008 in Chicago by Tobias Mayer ○ simulates Scrum process
- 4. How it lookslike? Team members pass the balls amongst the whole team. When the ball goes throw all team members it is produced.
- 5. Rules The basic rulesare: ○ The balls must have air time ○ Balls that hit the floor don’t count, and have to be returned to the starting point to get them back in play ○ No balls to your direct neighbour ○ Start point = End point (i.e. the container) ○ Iteration = 2 minutes ○ In between = 1 minute, to review and plan ○ Play 5 iterations
- 6. What we aregoing to do? Agenda: ● simulate plan-driven approach ● simulate change-driven approach ● analyze lessons learned
- 7. So we need twosets of rules for two different approaches!
- 8.
- 9. Rules for plan-drivenapproach Additional rules for plan-driven approach: ● Number of balls to use is predefined ● Number of balls to be produced is predefined ● Planning phase: 3 min ● Production phase: 3 min ● Review: 1 min
- 10. Rules reloaded The basicrules are: ○ The balls must have air time ○ Balls that hit the floor don’t count, and have to be returned to the starting point to get them back in play ○ No balls to your direct neighbour ○ Balls must be touched by hand ○ The ball is produced when it passed through all team members ○ Teams can use whatever it wants during the production phase ○ The team can not change its process during production phase ○ Teams are accountable for counting the produced balls quantity
- 11. Plan-driven approach retrospective ● Whathappened? ● Did you want to change the process? ● What will happen if the production phase lasts for 15 minutes?
- 12.
- 13. Rules for change-driven approach Rulesfor change-driven approach: ● Team can use as much balls as it likes ● Team defines the quantity of balls it is committed to produce ● Planning phase: 1 min ● Production phase: 1 min ● Review: 1 min ● Play 3-5 iterations
- 14. Rules reloaded The basicrules are: ○ The balls must have air time ○ Balls that hit the floor don’t count, and have to be returned to the starting point to get them back in play ○ No balls to your direct neighbour ○ Balls must be touched by hand ○ The ball is produced when it passed through all team members ○ Teams can use whatever it wants during the production phase ○ The team can not change its process during production phase ○ Teams are accountable for counting the produced balls quantity
- 15. Change-driven approach retrospective ● Andwhat happened at this time? ● Did you want to change the process? ● Did you change it? How? ● What was the iteration that felt great?
- 16. Lessons learned What didyou learn today? … Fill it by yourself!
- 17. But think about… ●What made the teamwork? ● How time pressure affects the team? ● How did you improve as a team? ● In what simulation production process is more cost effective? ● Why the team began to show more predictable result?
- 18. Deming cycle Is itbetter to have a long feedback loop or a short one?
