This strategic plan is developed jointly by the ATLAS user community and the Physics Division at Argonne National Laboratory. This plan is a public document, hence available to the entire ATLAS user community, and is updated as the need arises. In practice, the community discusses this plan at regular ATLAS Users Workshops, the most recent of which was held on August 8-9, 2009. The users’ executive committee and ATLAS management then work together to incorporate the outcome of these workshops into the strategic plan.

This plan provides the scientific and strategic vision for ATLAS, the goals for its future capabilities and the expected path forward in light of existing budget constraints.
