Incremental & Iterative Development

Timeboxing

allows for retrospectives

Iterative development

an approach to building software (or anything) in which the overall lifecycle is composed of several iterations in sequence. Each iteration is a self contained "mini-project" of development activities.

Evolutionary Delivery

feedback; a refinement of incremental delivery in which a vigorous attempt to capture feedback regarding the installed product and use it to guide the next delivery.

Incremental Delivery

future prediction; the practice of repeatedly delivering a system into the marketplace in a series of expanding capabilities

Cone of Uncertainty

narrow cone (aka more certainty) after each iteration

Incremental development

the act of growing the system incrementally with new features, iteration by iteration.

Contract

tries to solidify all sides of the project triangle (scope, schedule, cost) ex. pay monthly (iteratively) and receive some software product (incrementally)
