Development model of the project

Project development Model:

1. Waterfall Style:

Design the best algorithm you can think of and start implementing

For example: To be a motorcycle, to start with the integration of thinking about how to do the motorcycle

Disadvantage: The development cycle is too long to think about the optimal algorithm does not start to run code

2. Iterative:

Iterative these two words I see also little, literally can not understand, for example, do motorcycles, first make a bike, and then the development time, be able to hand over a semi-finished product, and then on the bike to join the engine
