In the MVC approach, we create three distinct concepts in our code.
Models - piece of the system that interacts with data directly. Contains the logic, functions, and rules that manipulate data.
Views - output presented to user. May include images, tables, styling, page formatting.
Controllers - recognizes changes and events (e.g. user interaction). Controller will call appropriate model and appropriate view upon change.
NOTE: Typically, models and views are decoupled, have no awareness of each other. The controller acts as a middle man.

The Waterfall approach to project management recognizes the projects are typically cyclical, and builds that recognition into its five stage approach to management:
1) Requirements - gathering feature requests, scope, information
2) Design - wireframing, pseduo-code, etc
3) Implementation
4) Verification - testing and debugging solution
5) Maintenance - Database maintenance, new tasks created by the discovery of bugs--which initiates another waterfall cycle.
