[OSLC-Metrics] effort by role issue in Proj. Initiation primer

[Arthur Ryman]

Andy,

I said the purpose of the Primer is to give people a good overall 
understanding of the service. It is not intended to be an exhaustive 
desciption of the service. That is what the actual speciifcation is for, 
I'll add links from the Primer to the Spec to provide more detail when the 
Spec gets fleshed out.

I also said the example should be self-consistent, so if we show the 
content of an XML response, then we should only refer to data actually 
contained in it later. 

I will fix up the XML example to include the effort by role, but I'd like 
to freeze the example after that and move on since time is limited.

Arthur, I realized too late in the discussion that when you were saying 
the "example should be simplified" and "now the example is inconsistent" 
that by "the example" you meant the XML representations in the primer.  I 
thought you meant "Tsunami 1.0", "Guesstimator" etc. in the English 
narrative, and I didn't see why having multiple standard costs was too 
complex, since that's a key element of the interaction.  I thought I was 
keeping it simple by not bringing in the whole discussion of "standard 
roles" etc, and that anyone who can get that far into the primer would 
have no trouble understanding that there isn't a single standard rate for 
the whole team, so it's simple enough to understand, but that this is a 
key concept so it should be part of the narrative.    Of course, the 
narrative and the XML should be in synch, and I didn't do that (which I 
indicated by a note) so that work still needs to be done.  Arthur, I think 
you're the best person to synch it up, since you've done the XML 
representation for the pieces. 

My key point in bringing it in there is this...there are two pieces of 
information that the portfolio manager will be interested in around this 
area: 

a)  A quantile representation of the probability distribution of total 
labor cost---but to compute that total labor cost at each probability 
level, the estimation tool needs to know the standard rates (plural!!!) 
that the portfolio management tool expects to use). 
b)   The breakdown of effort by role (there's actually more complexity 
here, but I'm keeping it THIS simple)  at the specific desired level of 
confidence
