Management does not know what a system is.
Management of outcomes may not be any more than a skill. It does not require knowledge.
There must be consistency in direction.
Anyone that enjoys his work is a pleasure to work with.
One cannot be successful on visible figures alone ... the most important figures that one needs for management are unknown or unknowable, but successful management must nevertheless take account of them.
It is not necessary to change. Survival is not mandatory.
