In terms of the 8 different payment schemes I was specifically referring to what we call 'payment curves' (see attached graphic) as opposed to payment regimes such as cost+ (time and material), fixed price, cost + fixed fee, etc. In this light these are grouped into 5 main families with a couple of variations inside each. These are as follows:
- 'all or none' payment curves
- Linear payment curves
- Non-linear payment curves
- Alternative payment such as demerit point and visual payment curves
- Matrix payment curves
The intent of this discussion is to simply highlight that the choice of payment curve, similar to the choice of performance measure and level, can have a significant impact on the success (or otherwise) of the overall performance management framework. My blog (www.performancebasedcontracting.com) has 3 posts specifically on this topic including the graphics.
I hope this helps and answers your questions. However, please let me know if you have any further questions.
Whilst it's the way that a lot more suppliers seem to be going, if you think about this in with your procurement hat on - and that is what's going to happen at the end of 3-5 years - it's tough to see you doing anything but just rolling this over (and over and over again) as someone else has all of your data on their server.
At the risk of being awfully contentious, my own experience is that in a lot of circumstances, there's little consideration of whole of life costs - especially with that thinking about what's to happen in 3-5 years. Right now, many of these purchases done right now are flying under the radar of procurement teams because they're below procurement limits or just being called operational expenditure within business delegated authorities.
That said, one of the benefits that I've also seen is that upgrades happen automatically on the server of the host without the business having to create teams to do this, especially where there was a major upgrade - which were previously a big financial impact on many businesses.
