Collaborative development proved to be a key of the success of the Site Status Board (SSB) which is heavily used by the experiments at the Large Hadron Collider (LHC) at CERN for the computing shifts and site commissioning activities.SSB is a tool that helps Virtual Organizations (VOs) to monitor the performance of sites.The selection, criticality and combination of monitoring metrics fall clearly in the domain of the VO administrators.Therefore VO administrators and computing teams define monitoring metrics and custom views of the monitoring data, in addition to developing sensors and data publishers.The responsibilities of the SSB team include development and support of the SSB framework and the SSB services which store, aggregate and visualize monitoring data.The collaboration extends beyond the customization of metrics and views to the development of new functionality and visualizations.SSB Developers and VO administrators cooperate closely to ensure that requirements are met and, wherever possible, new functionality is pushed upstream to benefit all users and VOs.The contribution covers the evolution of SSB over recent years to satisfy diverse use cases through this collaborative development process.
