Agenda JASS 2006

What is „Agility“? „Agility is the ability to both create and respond to change in order to profit in a turbulent buisness environment. “ [Jim Highsmith, Agile Software Development Ecosystems, Preface XXIII] JASS 2006

Chaordic – Chaos mixed with order • Natural blend of Chaos and Order • Most organisations and projects exhibt chaordic structures • Is about self-organisation and selfgovernance, evolutionary like nature • Often used to describe agile software development processes. JASS 2006

Management and Developing before Agile • Countermovement to heavy and bureaucratic software development processes • Waterfall • V-Modell • Beginning in the early 1990 ies, became publically known in 1999 with Kent Becks „Extreme Programming“ JASS 2006

Agile Manifesto • Individuals and interactions over processes and tools • Working software over comprehensive documentation • Customer collaboration over contract negotiation • Responding to change over following a plan [Source: Agile Manifesto, http: //agilemanifesto. org, 3/29/2006 ] JASS 2006

This does NOT mean. . . • . . . processes and tools don‘t matter. • . . . that we need no documentation. • . . . that we need no contracts. • . . . make a plan and follow it is obsolete. JASS 2006

Principles • Keep it { simple, small } and { stupid, straigthforward, smart } (KISS) • Use resources carefully • „Chaordic“ nature of projects and organisations JASS 2006
