Leaving the definition of agile aside for the moment, doesn’t the fact that the 
BSIMM measures organisation wide activities but not individual dev teams mean 
that we could be drawing inaccurate conclusions from the data?  E.g.  if an 
organisation says it is doing Arch reviews, code reviews and sec testing, it 
doesn’t necessarily mean that every team is doing all of those activities, so 
it may give the BSIMM reader a false impression of the use of those activities 
in the real world.

In addition to knowing which activities are practiced organisation wide, it 
would also be valuable to know which activities work well on a per-team or 
per-project basis.

Agree that the split between agile and not-agile would be arbitrary at the 
organisation wide level.  But deciding on an arbitrary line, or better yet an 
arbitrary scale of agility on a per-project level shouldn’t be too difficult.  
If we need to start somewhere, then I think borrowing from devops couldn’t 
hurt, where they measure agility by:
- frequency of code deployments
- lead time from code deploy to running in production

With the BSIMM’s objective of just describing activities it wouldn’t be 
necessary to promote agile or agile security practices.  But it would be 
interesting to know that if an organisation happens to have chosen agile or 
continuous delivery as their software dev methodology, then how are they 
integrating security into that process?  The burning questions I have regarding 
agile and continuous delivery and security are:
- What mixture of the BSIMM activities work well in a continuous delivery style 
environment?
- As you move from less-agile to more-agile, which activities tend to fall away 
and which are more emphasised?
- How are the security specialist and time heavy activities like attack models, 
sec arch review and pentesting performed when new code is pushed to production 
daily?
 
The BSIMM seems to be the only place where this type of data exists or could be 
captured- so would be nice to be able to extract this data from it; or include 
these types of questions in future versions.  The devops survey(*) is another 
potential, but as yet they don’t capture security specific activities.
