This short video explains
This short video explains the differences between Agile and Waterfall, and gives an example for both of them.
Several years ago, projects were managed in waterfall project where we Tasks are executed in phases in a linear and sequential way and progress flows downwards in one direction like a waterfall. Each of these phases represents a distinct stage and each stage generally finishes before the next one can begin.
Waterfall was organized in such a way that projects had to be finished within a certain budget, fixed scope, fixed time and a good quality, which was almost never the case and the customer was always unhappy.
Agile came to solve these issues, with the 4 values and the 12 principles we create things differently. In agile we build products incrementally and iteratively which that helps teams deliver value to their customers faster and with fewer headaches.
Instead of betting everything on a "big bang" launch, an agile team delivers work in small, but consumable, increments.We start with a small piece of work and we go through the design, develop, test and deploy, the feedback from the customer and stakeholders is then collected and fed back into the cycle.
