A better example is a machine shop that usually services the electronics industry then trying to service the medical device industry. The basic skills may be the same but the level and type of required ISO certification is different, as is the type and level of record keeping, internal auditing, traceability, method of cleaning and packaging, materials segregation, allowable chemicals and solvents, product finishing, machine tool inspection (servicing, preventative maintenance, biological particle checks etc), process control and in-process and final inspection. That’s why you find machine shops that tend to specialise in particular sectors and subsectors. For example one company may be well able to service a medical equipment manufacturer but be unable to service a medical implant manufacturer. This level of specialisation and sub-specialisation is the rule rather than the exception.
If there are particular areas or pitfalls involved in designing a facility that requires inspection by the Irish Medicines Board I would rather hire someone with experience in that area.
When I was with another firm they did a clean room facility as part of a large FAB installation, one of the first in Ireland at the time.
The brief was carefully formulated with the client to take everything into account.
Specialists were called on to give advice on several aspects of the building.
There was a research period, as with any project an architect does.
Then the building was designed, approved and built.
Architects specialize in design.
Architects don't specialize in getting pigeon-holed.
People in a profession have already specialized - in that profession!
Its a logical fallacy to treat the professions as needing further specialization.
People trying to "get" a barrister who "specializes" in certain court actions make the same mistake.
The issues is whether or not the barrister is of high quality, not where the preponderance of his cases arise.
And barristers, like architects are as good as their last case/building.
To turn your argument totally upside down, I would be much happier to see an architect whose experience and achievements show a wide range of abilities and a mastery of design over several building types and scales.
That way I could be more certain that he would be up to the task of co-ordinating the several disciplines that a specialist class of building would require.
I would be very wary of considering someone for a specialist FAB installation if that person or firm had "only" done schools.
