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 toprofit in a turbulent global business environment The ability to quickly reprioritize use of resources whenrequirements, technology, and knowledge shift A very fast response to sudden market changes andemerging threats by intensive customer interaction Use of evolutionary, incremental, and iterative deliveryto converge on an optimal customer solution Maximizing BUSINESS VALUE with right sized, just-enough, and just-in-time processes and documentationHighsmith, J.

Respect. Always treat people with respect and dignity Peaceful. Be slow to speak, anger, and overreact Composed. Walk away from a situation when in doubt Space. Give space, dont crowd, and dont be pushy Patience. Be calm, cool, rational, and even-tempered Objective. Keep focus and dont escalate or exacerbate Maturity. Strive be a role model of maturity at all times Listen. Observe and wait for subtle cues to add value Guide. Gently and respectfully guide, correct, and lead BE OPEN OBSERVE LISTEN LEARN CONNECT RESPECT PRIVACY
