Agile Framework Crystal

Crystal Clear is a member of the Crystal family of methodologies as described by Alistair Cockburn and is considered an example of an agile or light weight methodology. Crystal Clear can be applied to teams of up to six or eight co-located developers working on systems that are not life - critical. Crystal is actually comprised of a family of agile methodologies such as Crystal Clear, Crystal Yellow, Crystal Orange and others, whose unique characteristics are driven by several factors such as team size, system criticality and project priorities. This Crystal family addresses the realization that each project may require a tailored set of policies, practices and processes in order to meet the project’s unique characteristics. Several of the key tenets of Crystal include teamwork, communication and simplicity, as well as reflection to frequently adjust and improve the process.
