Agile Model

Inception: Knowing what to build and where you should start

Elaboration is the process of determining the details of a product feature

Construction is the process of development

Transition is the process of deployment

Agile Development

Agile visibility

Burn down is a work left to do versus time

Burn up chart shows how much work has been completed, and the total amount of work

Velocity tracking is the act of measuring said velocity. The velocity is calculated by counting the number of units of work completed in a certain interval, the length of which is determined at the start of the project

Agile Retrospective is an event that happens at the end of iteration. It is a tool that shall help to plan and improve next iteration better.

Agile Retrospective is a • time of reflection • where You talk about what went well and what did not go well• where You wonder what could be improved

Thee basic questions in Agile Retrospective:• What did we do well?• What did we do wrong?• What could be improved?

SDLC of Agile

Home grounds of different development methods

Open Source

• Denoting software for which the original source code is made freely available and may be redistributed and modified

– Cheap

– Already built up engine

– May or May not fully available with documentation

– Various flavors, platform

Vendor Specific

• Refer to the standard products covers legal aspects of support, warranty, quality etc.

– Cost and price varies

– Highly competitive

– Support and Training availability

– Better versioning controlling
