The Square Kilometre Array (SKA) will be the world's most advanced radio telescope, designed to be many times times more sensitive and hundreds of times faster at mapping the sky than today's best radio astronomy facilities. The scale and advanced capabilities of the SKA present technical challenges for co-ordinating and executing observations. This paper discusses the requirements placed on the SKA's observation sequencer - the Observation Execution Tool - and the functions it must perform. A design and prototype implementation of the Observation Execution Tool are presented, with initial results showing that a Python implementation using a message-driven component architecture could be capable of meeting the SKA's requirements.
