What is a Best Practice?
Proven way of doing something
demonstrated beyond any doubt that it really works
Evidence that this is better than any other way
safer AND/OR
faster AND/OR
more reliable AND/OR
lower cost AND/OR
whatever metrics matter to you

SUMMARY: You’ve got to have miles in the bank
Demonstrated in the field
Measured superiority
“Ladies and gentlemen, here is the result of event No 9, the one mile. First, No 41, R. G. Bannister, of the Amateur Athletic Association and formerly of Exeter and Merton Colleges, with a time that is a new meeting and track record, and which, subject to ratification, will be a new English native, British national, British allcomers, European, British Empire and world record. The time is three . . .”
The rest of the announcement was drowned by the uproar of the crowd.

To create a Best Practice:
State your goals
Come up with the best design that you can
Test it extensively
Fix the things that didn’t work very well
Test it all over again
Keep doing that until everything meets your goals
Do a reality check - compare with the status quo

In general we expect NeSSI to contribute by:
Making the mechanical things easier
quicker to design and build
overall lower cost of build
Making it easier to look after systems
efficient use of technician and engineering time
improved reliability
lower cost of ownership
Smart diagnostics minimizing downtime
higher availability
increased credits captured

The score card to date

13. NeSSI systems: the approach to a Best Practice
NeSSI Generation I: miles in the bank
We have a proven operating envelope of gases and liquids (up to diesel)
We have seen the cost of components come down to a premium of about 10%
We have seen the overall cost of build reduce by about 30%
We have demonstrated technician acceptance
We have demonstrated self contained systems
We have demonstrated SAM jr

The Tipping Point
“The moment when an idea goes from being just another word on the street to becoming THE way that everyone thinks.”
NeSSI is making good progress on its approach to becoming a Best Practice
Decreasing costs
Solid field experience with Gen I
Commitment to develop Gen II
DoE project support of Gen III
The Tipping Point for NeSSI could be close at hand
