4 What is Agility? A-gil-i-ty (ə-'ji-lə-tē) Property consisting of quickness, lightness, and ease of movement; To be very nimble The ability to create and respond to change in order to profit in a turbulent global business environment The ability to quickly reprioritize use of resources when requirements, technology, and knowledge shift A very fast response to sudden market changes and emerging threats by intensive customer interaction Use of evolutionary, incremental, and iterative delivery to converge on an optimal customer solution Maximizing BUSINESS VALUE with right sized, justenough, and just-in-time processes and documentation Highsmith, J. A. (2002). Agile software development ecosystems. Boston, MA: Addison-Wesley. 4

5 What are Agile Methods? People-centric way to create innovative solutions Product-centric alternative to documents/process Market-centric model to maximize business value Frequent comm. Close proximity Regular meetings Customer Collaboration Multiple comm. channels Frequent feedback Relationship strength valued more than Contracts Contract compliance Contract deliverables Contract change orders Leadership Boundaries Empowerment Individuals & Interactions Competence Structure Manageability/Motivation valued more than Processes Lifecycle compliance Process Maturity Level Regulatory compliance Working Systems & Software Clear objectives Small/feasible scope Acceptance criteria Timeboxed iterations Valid operational results Regular cadence/intervals valued more than Documentation Document deliveries Document comments Document compliance Org. flexibility Mgt. flexibility Process flexibility Responding to Change System flexibility Technology flexibility Infrastructure flexibility valued more than Project Plans Cost Compliance Scope Compliance Schedule Compliance Agile Manifesto.
