Comments
\begin{itemize}
\item
There is much stability in the results. Sometimes, attriutes appear
infrequently (e.g. $cplx=3$ and $pvol=2$ and $sced=3$ and $time=3$).
But usually, it a variable is ``in'', it usuage repeats across the whole space.
\item
Usyally, if the best actions it is usually ``in'
for $a$ (able to change everything) then it is in for $s$ (strategic policies) 
Exception: $tool$ seems does not appear in $s$ (strategic policies) but does
appear in $a$ and $t$ (tactical policies).
\item Best actions are the same across all project sizes (expection: $rely$). 
This is possible:
e.g. COQUALMO reports its output normalized by size. But it is surprising\footnote{Ous:
are we sure different lines of code went in?}
\item
There are some time effects- obseve the ``staircases'' in $aa$ (automated analysis),
$ett$ (execution-based testing and tools), $pmat$ (process maturity), and
 $resl$ (risk resolution). The need
for more of these attributes increases over time.
\item
Low levels of automated analysis are useful (before, for
more specific projects, we never found anything less than 5 or 6 
to be useful)
\item 
Peer reviews is missing from the chart, as are 9 other attributes:
XXX \footnote{ous- please list the missing ones}
\item
Other attriutes are parially missing. e.g. in $tactical$, we never see
the 9 missing attribtes or $apex,letx,pcon,plex,rely,site,time$
\end{itemize}
