The Game of Pennies, Processes, and People

Interviewer: What is the significance of the penny game in Agile methodology?

Candidate: The penny game illustrates how individual productivity often falls short of overall team productivity. For example, let’s consider a team of six participants who play the penny game, first individually and then as a team.

Round 1: Individual Play

1. Instructions: Each participant stacks pennies alone for two minutes.

2. Outcome:

?? - Participant A stacks 10 pennies.

?? - Participant B stacks 8 pennies.

?? - Participant C stacks 5 pennies.

?? - The total is 23 pennies.

Round 2: Team Play

1. Instructions: The same participants now collaborate as a team for two minutes.

2. Outcome:

?? - They discuss strategies, such as who will hold the stack while others add to it.

?? - One participant may focus on stacking while others gather more pennies.

?? - Together, they manage to stack 40 pennies.?

Interviewer: Interesting! How would you explain this to someone resistant to Agile who prefers the traditional waterfall model for software development?

Candidate: Imagine a scenario where one person is responsible for moving 10 pennies at once; this can lead to delays. For instance, the handoff to the second person might take 40 seconds, and by the time the second person flips all the pennies and passes them to the third person, it could take another 35 seconds. Ultimately, this whole process might take 4 minutes to transfer all the coins to the last person. This reflects the traditional SDLC approach, where, after requirements analysis, development happens in a large batch followed by a handover for testing. Until testing is complete, the product isn't ready for the customer. If issues arise during testing, fixing them can lead to further delays, impacting costs and project timelines.

In contrast, if I apply Agile principles and instruct my team to flip and pass 6 pennies at a time, everyone remains engaged, allowing the customer to receive batch releases of 6 coins simultaneously. After just 3 minutes, all pennies would be flipped and delivered to the customer.

To further illustrate, we could try the same exercise with only 4 pennies to see the difference in delivery time. We could also run another cycle with just 2 pennies to highlight this difference even more.

The penny game not only demonstrates that team productivity exceeds individual efforts but also emphasizes how short-term planning can lead to success through the delivery of smaller, incremental pieces rather than larger batches.

Ultimately, the penny game is more than just a fun activity; it serves as a powerful lesson in adaptability and the value of teamwork. It highlights the importance of continuous learning through experimentation. Agile is about exploring, learning, implementing, inspecting, and adapting. In both business and the game, the key takeaway is that it’s not just about racing through tasks but about moving forward together-one penny, one project, one success at a time.

Conclusion:

Overall, the penny game serves as a practical demonstration of Agile concepts, making them easier to grasp and apply in real-world scenarios.

1. Collaboration and Strategy: In the team round, participants brainstorm and develop strategies together, realizing that dividing tasks (e.g., one person stacking while others bring pennies) maximizes output.

2. Enhanced Communication: The necessity for clear communication emerges as they coordinate their efforts, with participants sharing instructions and tips to foster unity.

3. Learning from Each Other: Participants can adopt techniques from one another, demonstrating how collaboration leads to skill development and innovation.

4. Collective Focus on Goals: The transition from individual goals to a shared team goal emphasizes the Agile principle of delivering value as a group rather than individually.

5. Reflection and Improvement: After each round, the team reflects on what worked and what didn’t, embodying the Agile practice of continuous improvement through retrospectives.
