Manifesto for Agile Software DevelopmentWe are uncovering better ways of developing software by doing it and helping others do it.Through this work we have come to value:

Individuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a planThat is, while there is value in the items onthe right, we value the items on the left more.

Still more space to thinking - “The Spirit of Agility for Bigger Problems”

• Big complex system-of-system problems • Multiple competing stakeholders• Many cross-dependencies in terms of

requirements, technical dependencies etc• Multiple Programs and Portfolio management etcCopy Right Reserved , Exelplus Services
