NOISE SOURCE SUPPRESSION: Proper specifications/modifications for/of various accelerator components allow the initial orbit motion without feedback to be minimized. ORBIT MEASUREMENT/CORRECTION: The remaining orbit motion must be measured and corrected; in particular the movement of insertion devices can induce significant orbit noise which needs to be compensated by means of feed-forward and/or feedback schemes. ``Top-up'' operation guarantees a constant heat load on all accelerator and beam-line components and thus allows for high mechanical stability. Together with the utilization of fast orbit feedback systems, ``top-up'' operation makes it possible to achieve sub-micron stability on a scale from ms to days. USER EXPERIENCE: Two beam-line scientists from the SLS kindly agreed to share their experience with the workshop participants. They offered insight into the orbit stability requirements for experiments at their beam-lines. STABILITY REQUIREMENTS IN 4TH GENERATION LIGHT SOURCES: Position and energy stability requirements in linear accelerator (linac) based 4th generation light sources are demanding and require the use of slow and fast feedforward/feedback systems. It was the organizer's deliberate intention to allow adequate time for discussions throughout the workshop. Coupled with the 38 excellent oral presentations of $\approx$20 min length ($\approx$80 % of the participants gave talks) this inevitably led to a very tight schedule, which additionally included excursions to the SLS and the Jungfraujoch as part of the social program.
