Waterfall vs. Agile Development

All forms of software development are some variation of the following cycle, it is called the Software Development Life Cycle (SDLC):

Analysis: Figure out what features and functionality is required in the software.

Design: Describe features in more detail, a functional design document.

Implementation: Build the software.

Testing: Test the software for each individual component, integration of components and user acceptance.

Evolution: Make updates or changes as needed

Waterfall vs. Agile

Waterfall: Waterfall aims to finish the entire program within one very large sequential series of events. In waterfall, you only move to the next stage after the first stage is completed and accepted. For example, you would only start coding after you figure out what functionality is required and how to achieve that functionality.

The goal of waterfall is to build the entirely of a product one stage at a time, so design only occurs once and you only have a functioning product at the end

Agile: As a form of iterative development, Agile breaks down the software into smaller functional components that are completed in sprints. Each individual subcomponent has its own cycle of analysis, design, implementation, testing and evolution.

The goal of agile is to have something that is functional at the end of each sprint and iterate over the mini-cycle many times adding new features and improvements

Overview

Beyond just agile and waterfall there are many other hybrids or other ways to develop software. Ultimately, to pick the best project management system requires you analyze what you want your software to do. If you have an app or program in mind, I recommend you to just try out making it. In the process of actually developing software, you will figure out how to manage it.
