Organizations Are Made Of People And People Are Not Machines

Treating organizations like machines and therefore people like parts in a machine is a recipe for failure though some of these efforts may marginally succeed due to other factors or simply by chance.

Talent is not ubiquitous and some talents cannot be taught to some individuals.
Some people are NOT replaceable.
Good processes and best practices alone do not equate to success.
Some teams do not gel because some people do not get along or are not compatible.  

There is no magic recipe of processes, procedures, rules, hierarchies, capabilities, functions, and/or methodologies for organizational success that works with just any group of people.

Organizations act as conduits that focus the will, energy, talent, strengths, and weaknesses of groups of individuals toward some goal or set of goals through the leadership of some individuals.

There is nothing wrong with good processes, procedures, rules, or methodologies but they are adopted and put into action by people within the the context of many unwritten and unspoken human and interpersonal processes, procedures, rules, hierarchies, and methodologies both conscious and subconscious that we all learn to live with.
