Abstract: The technology relates to determining service item management opportunities. One or more processors may receive a set of client data via communication network. The one or more processors may identify one or more service item management opportunities by determining service items in the set of client data which satisfy at least one or more rules and assign a confidence value to the one or more service item management opportunities. For each of the one or more service item management opportunities, a recommended intervention type based on the respective assigned confidence value may be determined and for each of the one or more service item management opportunities, a transmission may be caused by the one or more processors, via the communication network to an external device, of rendering information indicating the service item management opportunity and the recommended intervention type.

Abstract: A chair particularly useful for an auditorium utilizes spherical bearings to mount the bottom of the chair to upright standards. The spherical bearing includes a base portion and a top portion that are secured to the chair bottom to hold the spherical bearing roller. An axle extends through each standard to engage the bearings to support adjacent chairs. The axles are threaded to receive a nut to secure the axles to the standards.
