The LSA project will provide the high level software for the control of the LHC accelerator. A brief overview of the operating challenges and required functionality will be presented. We will highlight the underlying software architecture and the key features of its implementation showing, among other things, the importance of a sound database design. LSA has rolled out over the last two years providing software for TI8, LEIR, the SPS and LHC hardware commissioning. Examples of the deployed software will be given.
