'If you mentally block out the word "digitalising" and replace it with "computerising" then it all works so much better.'
That doesn't work here.
'the company is also winning "digital" contracts, too – including the digitisation of a number of train companies' front-end ticketing systems.' Aren't these systems already computerised and, therefore digital?
"we have a lot of demand to digitalise the front end of those legacy systems – rather than full legacy modernisation."
"Moran believes digital and legacy are not mutually exclusive."
In order to make sense of this one has to assume that either these systems aren't already running on digital computers or that she has some previously unknown meaning of "digital" in mind.
Did she get parachuted in from some entirely different industry?
