What is waterfall project management methodology? Is it better than Agile?

Waterfall project management originated in construction and manufacturing industry

Agile originated in the software industry

In waterfall one phase must be completed before another begins

In Waterfall project is broken into sequential stages

Each piece of the Waterfall project relies on the completion of preceding piece

In waterfall you cannot go back to a prior phase, you simply start and move to end

Agile methods break projects into smaller, iterative chunks, you can improve what you just delivered in last sprint

Agile is well suited to projects in which you expect scope and requirements to change and customer feedback is needed to make progress

The waterfall model works well for projects where scope and requirements are well defined
