HRMS, a distressed purchase?

I was provoked by this on Hackernoon, and wrote a little piece on HRMS systems. I have just come back from a Trade Union course on Employment Law and wonder whether the US based systems built for Silicon Valley behemoths are suitable for UK based SMEs. I reference the Gartner MQ which seems to have come on in the last two years; google it, you can get to see it from one of the companies in the top right quadrant but I like their functional breakdown.

I state that a “person” data model is key and finish with the following quote,

HR functions need to define their mission statement, somewhere between “stop the staff suing us”, and “delivering a self-actualising company”; only then can the needs of the software be defined and developed, bought or rented.
