Abstract: The Herschel Space Observatory, the fourth cornerstone mission in the ESA science program, was launched on the 14th of May 2009. As a cryogenic mission Herschel's operational lifetime is consumable-limited by its supply of liquid helium, estimated to be depleted by March 2013. Afterwards the mission will start a 4.75 year long post-operations phase. Originally it was considered sufficient to provide astronomers with raw data and software tools to carry out a basic data reduction, and no “data products” were to be generated and delivered. Following the realisation that the expectations of the astronomical community on the deliverables of an observatory mission evolved it was agreed to implement a single ‘cradle to grave’ data analysis system supporting the needs of all users for the whole project cycle. We will summarise the lessons learned during those ten years of Herschel data processing development, address the main challenges of this major software development project, and reflect on what went well, what needed to be adapted, and our open points.
