Re: [epf-dev] SEMAT OMG RFP, EPF response?

Bruce,
 
Having worked with EssUp/IJI, the driving force behind this proposal, I would be very interested in being involved in the discussion.
 
Kind regards,
John

Subject: [epf-dev] SEMAT OMG RFP, EPF response?


Dear EPF community,

There was a recent submission to OMG to propose a new process standard.
It is not based on SPEM or any of the work we have done in EPF, but rather is based on the SEMAT kernel work.
(For those who don't know this, EPF was originally based on SPEM http://www.omg.org/spec/SPEM/2.0/ )

Some  reasons given for why the proposal ignores SPEM is:

1. "lack of enactment support"
If this is a significant concern, then a set of requirements for what would be appropriate enactment support should be described in the RFP.
A goal to what people actually do vs. what they are supposed to do isn't a sufficient set of requirements.
There are some hints in the RFP, but they aren't clear:
"Methods can be queried to get guidance based on where you are and where you want to go"
- this seems to be about describing how the processes evolve during enactment - this could be a natural extension to SPEM

2."The notion of composable practices is not explicitly defined as a core concept in the SPEM metamodel"
This seems to be a gap which could be addressed by a SPEM update.  Note that both SEMAT and EPF have gone beyond SPEM and
added support for practices to their method offerings.  They both use similar concepts and provide similar capabilities, but not identical.
This kind of divergence is exactly the kind of problem that standards organizations like OMG strive to avoid, so the time
is ripe to add practices support to SPEM.

3. "UML profile ... might be more complex and not as user-friendly as a more domain-specific language"
There is also a MOF representation of SPEM, but in any case, any approach for simplifying is welcome, but doing something completely unconnected
doesn't make a lot of sense.

4. SPEM does not specify a kernel of "essential elements"
Both SEMAT and EPF define such a kernel, but use different terminology and have made different choices regarding those essential elements.
Again, this is where standards are valuable - they align the best of divergent ideas so that the entire community can benefit.
The EPF kernel has been defined and publicly available for some time.   It is well supported by both the EPF Composer and Rational Method Composer tools.
It is based on an extension to SPEM.
A natural path forward would be to take the EPF kernel and formalize it in an extension to SPEM, reconciling differences with the SEMAT kernel to the benefit of the entire community.  I propose an extension, because I think SPEM should remain capable of modeling processes that don't use a kernel, or
that use alternative kernels.

If this is a topic that interests you, and you would like to be involved in this discussion, please drop me a note.
