Business people often see features as a simple to-do list. But the reality of how features are built is vastly different and leads to missed deadlines and developers who reach their breaking point. This slide deck tries to illustrate the difference between what business people see and what developers really have to build.

1. How killer features
will kill your app
and kill your team
AKA Visualizing Complexity

2. What most people see
Features are a to-do list:
1. Time selector
2. Location selector
3. Event summary
4. Event detail
5. Scroll to see more events

3. What most people see
You can double the size of the to-do list, and that is still manageable.
1. Time selector
2. Location selector
3. Event summary
4. Event detail
5. Scroll to see more events
6. Map view
7. Location detection
8. Play videos
9. Loading animation
10. About us page

4. What a developer must build
Each feature is a circle

5. Features interact
5 features, 10 possible interactions. 15 things to manage and build. Not so bad.

6. Let’s “double” the features
Next slide shows the difference.

7. Ouch!
10 features, 45 possible interactions, 55 things to manage and build. Ouch!

8. Take away:
Visualize complexity. Don’t kill your app and kill your team with killer features.
