The Open Concurrent Design Tool (OCDT) is a community open software environment for concurrent and multi-disciplinary engineering of space systems in the early phases of the life cycle. It implements the data model defined in ECSS-E-TM-10-25 Annex A as well as the API defined in Annex C to realise an interoperable model sharing platform. OCDT is distributed under an ESA Community Software License to organisations in the ESA member states. OCDT is in operational use in the ESTEC CDF since September 2014, in support of more than 50 studies to date. It is also used in industry, ESA Academy and a number of technical universities. All documentation and source code is available on the OCDT Community Portal at There is a need to continue evolution of its capabilities, to resolve problems and to provide support to end-users and IT system administrators. The objective of this activity is to answer to this need for the next two years, from mid 2018 onwards
