IBEX is the EPICS based experiment control system now running on most of the beamlines at the ISIS Neutron and Muon Source, with plans to deploy to all remaining beamlines by the end of the upcoming long shutdown. Over the last couple of years we have added support for reflectometry and muon instruments, developed a script generator, moved from Python 2 to Python 3, and continued to build on our suite of device emulators and tests. The reflectometry inclusions required the development of a framework to maintain the complex motion control requirements for that science technique. Whilst it is desirable that IBEX is easily configurable, not all operations should be available to all users, so we have implemented functionality to manage such access. The COVID-19 pandemic has meant we have also had to adapt to greater amounts of remote experiment access, for which we developed systems covering both IBEX and the old SECI control system. This presentation will aim to provide a brief update on the recent changes to IBEX, as well as outlining the remote operation solutions employed

Most software development teams are proponents of Agile methodologies. Control system software teams, working at science facilities, are not always just developers, they undertake operations work, and may also be responsible for infrastructure from computer hardware to networks. Parts of the workflow this team interacts with may be Agile, but others may not be, and they may enforce deadlines that do not align with the typical agile implementations. There is the need to be more reactive when the facility is operating, which will impact any development work plans. Similarly, friction can occur between an Agile approach and more familiar existing long-standing risk-averse organisational approaches used on hardware projects. Based on experiences gained during the development of IBEX, the experiment control software used at the ISIS Pulsed Neutron and Muon source, this presentation will aim to explore what being Agile means, what challenges a multi-functional team can experience, and some solutions we have employed.
