SoftwareDevelopmentApproaches

AGILE

Agile is hot, but there are many misconceptions about it. Frequent delivery of working software or values is one of its core concepts. Delivery means hand over working software to customers to create values.

Development progress or prototypes are not working software; they create no values because they don’t operate in the production environment.

SCRUM

From the perspective of scrum.org, there’s no project manager but a product owner. They call the daily event as Daily Scrum instead of a daily standup meeting.

PERIODIC REVIEW

Periodic review, demonstration, and daily meeting (standup or being sat) are general management practices. They are not specific to Agile or Scrum.

WATERFALL MODEL

The Waterfall Model delivers at the end of the project. Customers may review a pile of user requirement specification (URS) documents after the requirement analysis; documented designs as the solution in documents as well. In each phase, customers get nothing real until the end of the project.

SPIRAL MODEL

The Spiral Model is an improvement of the Waterfall Model. It delivers at the end of the project but demonstrates prototypes or work products to customers after each iteration, which can be treated as a small waterfall.
