From a dollars in your pocket perspective, you prefer to dump Presto - including whatever cancellation fees would be owed to Accenture for ongoing services - and start over? How would that be financially responsible?
Yes. I believe, based on what GO Transit is paying, what TTC expects to pay, and what Vancouver and Salt Lake City have paid, that this would be by far the cheapest option both immediately (next 3 years) and long-term (next 20 years).
Presto next generation (yes, they call it that) is intended to support open payments.
Yes, at great expense (substantial contract adjustment). PRESTO, by the time is it implemented across GTA including TTC, plus Ottawa will be in the $1.5B to $2B range.
I'm very confident we could have an off-the-shelf open payment based system fully implemented on all of the agencies that signed on to PRESTO plus TTC by 2013 for a fraction (1/3rd) of the price of what PRESTO still requires for completion (Ottawa, TTC, open payment, fixing all of the usability issues, etc.).
This doesn't include the fact that Accenture's maintenance agreement will be up for renewal on damn near the same day TTC finishes an implementation. Accenture has all of the expertise on PRESTO and we (Metrolinx) has none. It would take years to bring another contractor up to speed. That means we either renew with Accenture at Accenture's price or abandon PRESTO in favour of a different "pluggable" system where you could replace the company doing the maintenance.
Of course, as I said, it is politically infeasible to do this. If this was a private business venture and I was the CEO, PRESTO would be eliminated at the earliest opportunity due primarily to known future costs and the risk a single source vendor gives.
At very least, I would bring in a shadow contractor so there are two potential organizations that could take it over.
In the mean time, I keep waiting for the press to do a freedom of information request on the Open Payment tender results the TTC made.
