What is Agile — Scrum

Why Agile?

Classical waterfall model

Freezing nature of each phase(because next phase is started once previous is completed).
Less or very little interaction with stakeholders(because stakeholders interact with developed product at the last phase)
Hard to welcome change requests, if changes has to be made, it will in validate previous phase work.

Scrum

Iteration vs Incremental models of development

Scrum Artifacts

Product Backlog (contains everything required to be the part of product)

Sprint backlog (things a team commits to deliver in an iteration/sprint)

Increments (builds — deployable work as agreed with stakeholders)
