This joint WLCG and HSF workshop looks forward to the common challenges faced in HEP Software and Computing in the next decade, when the HL-LHC will start and the LBNF facility will become operational. Major programmes of work in software and computing have been identified as a result of the HSF's Community White Paper process, which published its Roadmap in December 2017 and now is the time to start implementing them.
In the workshop we will look to identify prototypes that will clarify the best and most promising lines of work for the next few years. There will be many plenary sessions, to engage the whole community in discussion of the challenges ahead and to find common projects as much as we can. Parallel sessions will allow working groups to make real progress on their goals.
