description
The objectives of this workshop are the following: Use two 45 min activities to simulate the software development cycle. One will make use of a Waterfall approach, while the other will make use of an Agile approach to help participants experience the different outcomes of each methodology. Introduce Agile as an adaptive, intuitive learning experience while cautioning participants that it is not a silver bullet. (People OVER Process.) Demonstrate and emphasize the importance of communication and feedback on software projects. (Collaboration OVER Throw-It-Over-The-Wall.) Assign participants to different roles that exist within a development team to help them look at software development from different perspectives and gain better understanding of and respect for team work.

No talking. Only written communication
End delivery is the drawing of the product
Coding = Drawing
Architects cannot draw [code]
Timings are important. Please stick to the time
Some rules!

What did not work?
What will we do differently?
Waterfall Retrospective

Based on the learnings, what are we going to do different?
Let’s break all walls
But...Only written communication to be fair
Architect can actually draw!
Instead of 14 mins, we have 7 mins

Waterfall Approach Agile Approach
Phased Iterative and Incremental
Working software in final phase Working Software every build
Different people involved in different phases- context is lost.
Communication overhead and uses low quality communication channels.
Same Set of people- context is carried over.
Less overhead and uses high quality communication channels
Verification is done at final stage Verifiability driven
Predictive Planning Adaptive Planning
Less visibility- artifacts, prototypes More Visibility- working software
Changes accepted at certain stages only Changes embraced
Key Differences
