41 Mr Moxon has deposed that, if there is a problem with the hardware or software for the Bureau business, Mr Woodward is "the only person with the technical skills capable of fixing the problem". As far as the Southpac software is concerned, whilst there are other software developers, Mr Moxon has deposed that Mr Webb, the Manager of the User Support Division, is the person who is able to rectify issues faster than anyone else, based on his experience and involvement in the software design. Mr Woodward, the Manager of Research and Development, is described as the "major person to support John Webb if there is a critical failure of Southpac's software." Mr Webb specialises in software rectification and Mr Woodward in hardware rectification. Mr Webb and Mr Woodward are not allowed to take leave at the same time, to ensure that there is continuous support for the systems.
