Who should manage design?

From a thread on LinkedIN dated 16 December 2011:

Design Management is very simple.

1)  Make a list of what design information is required to execute the contract

2)  Decide who is to produce what, particularily who is co-ordinating the design

3)  Decide when it is to be done by to allow sufficient time for procurement and construction to take place within the contract programme

4)  Decide who needs what information during the design process

5)  Do it

Architects are generally rubbish at this, which is why contractors employ Design Managers.

If Architects do not want to loose this skill set as well as having already lost Project Management, then Architects must take the responsibility as leader of the design team and effectively manage the design team.  It really is not that hard.

I am both a Chartered Architect and a Design Manager with many projects under my belt.

All the answers can be found in "Co-ordinated Project Information for building works, a guide with examples" published November 1987 (and in previous and later CPI publications).  There ain't nuthin’ new!
