I see this pattern so often: a company is not delivering the expected results. And boom - management decides to change the structure. New departments, people moving. Networks lost.
Some say "In what re-organization are you working"?
My believe: it's NOT about structure. It's about people, network, patterns of interaction and trust, and, of course, processes.
And the sad thing is: with every structural reorganization, most attention and energy is spend on structure. And, with most "change capital" spent, people struggle to build up new network, patterns and processes (usually outside the sponsorship of management...) to deliver the same results (and in the beginning less) as a before.
Management, please: it's people, supported by their netwerk, interactions, trust and processes that deliver results. Structure is not the main thing, that's about power, and not about results...
