The Technical-Rational Perspective

• Organization as a closed mechanical system
  (watchlike mechanism)
• Role of manager to design a more perfect
  mechanism by closely studying and redesigning the
  parts (jobs, tasks, people and machinery)

7
The Behavioral Perspective

• Organization as an open, biological organism
• Role of manager is to assist the organization in
  its quest for survival by continually redesigning
  the organization so it can fit or adapt to its
  environment

8
The Behavioral Model of Management Activities

• High volume, high speed work
• Variety and fragmentation
• Current Issues, ad hoc, specific
• Complex web of interactions, contacts
• Strong preference for verbal media
• Control of the agenda

Postmodern EraThe Cognitive View

• Organization as a knowing, sentient organism
• Role of manager is to use his or sense-making
  ability to properly define the situation of the
  organization so it can act (perceive problems and
  define solutions), and to build the information-
  and knowledge processing organizational
  infrastructure

Two Different Viewpoints

• Old view Workers must be told what to do, do not
  want to work hard and either do not know or do
  not care about the goals of the firm
• Contemporary view Employees and managers know
  what to do, want to work hard and succeed, and
  believe in the goals of the firm
