My original exposure to Six Sigma was through Motorola and DEC and it was
early-on in their programs.  The methods were, I thought, rather seriously
flawed.

Perhaps the methods have changed since then, I've read little about it in
recent years.

What caught my eye was the remark that 'Six Sigma is very strong on
methods'.  Because there is an emphasis on method, it doesn't necessarily
follow that the methods are "strong".

The methods are also based on theory (mostly statistical theory) and
constitute knowledge also.  I don't view this as a continuum and that
methods and SoPK and methods are two different points on the continuum; they
are intertwined and SoPK includes methods.
