More rapid decisions
Less certain environment
Less clarity about means/outcomes
Requires more cooperation

Process
Required because
– no one person has enough info to make all
major decisions

credibility to convince many
Relies less on hard data
Guided by powerful coalition
Permits trial and error approach

Choice:

Choice Processes in the
Carnegie Model
Uncertainty
Information is
limited
Managers have
many constraints
Conflict
Managers have
diverse goals,
opinions, values,
experience
Coalition Formation
Hold joint discussion
and interpret goals
and problems
Share opinions
Establish problem
priorities
Obtain social support
for problem, solution
Search
Conduct a simple,
local search
Use established
procedures if
appropriate
Create a solution
if needed
Satisficing
Adopt the first
alternative
that is acceptable
to the coalition

The Incremental Decision
Process Model
·
Identification Phase
– Recognition
– Diagnosis
Development Phase
– Search
– Screen
– Design
Selection Phase
– Judgment (evaluation – choice)
– Analysis (evaluation)
– Bargaining (evaluation – choice)
– Authorization
Dynamic Factors

Learning Organization Decision Process When
Problem Identification and Problem Solution Are
Uncertain
PROBLEM IDENTIFICATION
PROBLEM SOLUTION
When problem identification is
uncertain, Carnegie model applies
When problem solution is
uncertain, Incremental process
model applies
Political and social process is
needed
Incremental, trial-and-error
process is needed
Build coalition, seek agreement,
and resolve conflict about goals
and problem priorities
Solve big problems in little steps
Recycle and try again when
blocked
