In the context of agile software development in New Zealand and Australia, this paper examines the organizational agility related practices with agile software development. The paper looks at agile software development practices in established software development teams and proposes further practices based on organizational agility concepts that can support the agile software development manifesto. With a focus on the organizational agility for agile software development, this study adds to the limited body of research into theories for agile software development. The survey method is used in in conjunction with partial least squares (PLS) method to examine the organizational agility practices that best support agile software development.

Our findings suggest that, knowledge management, organizational culture, organizational learning, competencies, responsiveness, speed, team effort, and workforce agility are vital elements for achieving software development agility.
