So, around half or even three quarters of dis-satisfaction
I have the notion that satisfaction would be greater if IT wasn't saddled with implementing the latest new shiny simply because the CEO's nephew likes it and wants the bragging rights.
Last year one of my important customers abandoned a Helpdesk application that was providing reliable numbers and complete reports on the Helpdesk activity levels. They were influenced by the siren song of a vendor no doubt promising better analytics and an interface via web, of course.
Result ? After having transferred everything over, they found out that there are no reports, just pages and pages of data, summaries and percentages. So now, they have an inferior tool that needs, obviously, some bespoke programming to provide the results that the previous application already delivered.
Methinks that somebody should have asked a bit more questions about what the new shiny provided in reporting before signing off on the purchase.
I'm convinced that there are a lot of projects out there that follow the same result template.
