Desing principles: tensions and synergies
2 likes401 views
The document outlines a workshop that focuses on design principles, specifically exploring tensions and synergies through a hands-on setup that includes implementing user stories based on the Game of Life. Participants work in pairs to understand design principles, showcase their changes, and discuss their impact on additional principles. The workshop emphasizes interaction, creativity, and feedback while illustrating concepts like encapsulation and single responsibility.
Desing principles: tensions and synergies
- 1. Design Principles Tensions & Synergies Ilias Bartolini J u l y 2 0 1 4
- 2. 2 HOW IT WORKS ● Divide into pairs ● Start setup development environment ● Explain the tensions & synergies ● Choose a design principle or rule ● Game of life ● Implement a new user story (30min) ● Showcase changes How did it affect other principles? Post-it!! Repeat ● Conclusions ● Feedback

- 9. 9 Conway's Game of Life 1. Any live cell with fewer than two live neighbours dies, as if caused by under-population. 2. Any live cell with two or three live neighbours lives on to the next generation. 3. Any live cell with more than three live neighbours dies, as if by overcrowding. 4. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life
