Agile management or agile project management is an iterative and incremental method of managing the design and build activities for engineering, information technology, and new product or service development projects in a highly flexible and interactive manner, for example agile software development. It requires capable individuals from the relevant business, with supplier and customer input. There are also links to lean techniques, Kanban (かんばん(看板)?) and Six Sigma. Agile techniques are best used in small-scale projects or on elements of a wider program of work, or on projects that are too complex for the customer to understand and specify before testing prototypes.
Agile techniques may also be called extreme project management. It is a variant of iterative life cycle where deliverables are submitted in stages. The main difference between agile and iterative development is that agile methods complete small portions of the deliverables in each delivery cycle (iteration) while iterative methods evolve the entire set of deliverables over time, completing them near the end of the project. Both iterative and Agile methods were developed as a reaction to various obstacles that developed in more sequential forms of project organization. For example, as technology projects grow in complexity, end users tend to have difficulty defining the long term requirements without being able to view progressive prototypes. Projects that develop in iterations can constantly gather feedback to help refine those requirements. According to Jean-Loup Richet (Research Fellow at ESSEC Institute for Strategic Innovation & Services) "this approach can be leveraged effectively for non-software products and for project management in general, especially in areas of innovation and uncertainty. The end result is a product or project that best meets current customer needs and is delivered with minimal costs, waste, and time, enabling companies to achieve bottom line gains earlier than via traditional approaches.
The Agile Project Leadership Network provides a community of practice for those using Agile methods, with international conferences and online forums. Their "Declaration of Interdependence" extends the Agile Manifesto further into the value stream and emphasises the collaborative, whole-business nature of this work.
Agile Methods are mentioned in the Guide to the Project Management Body of Knowledge (PMBOK® Guide) under the Project Lifecycle definition:
Adaptive project life cycle, a project life cycle, also known as change-driven or agile methods, that is intended to facilitate change and require a high degree of ongoing stakeholder involvement. Adaptive life cycles are also iterative and incremental, but differ in that iterations are very rapid (usually 2-4 weeks in length) and are fixed in time and resources.
