Road Maps - What standards are 

being worked? (*DE Example)

Process Maps – Provides pointers 

for what standards should be 

established. (*SR Example)

Different Processes Require 

Different Kinds of Standard (i.e., 

not all standards are the same, 

nor can they all be judged using 

the same metrics.)
