Formulate Alternatives
Accomplishments
Put together a team
Established a shared vision of the status quo
Identified problems
Defined planning objectives
Defined measures of performance
Delineated constraints
Next We Formulate Alternatives
to the Status Quo
Alternative Formulation
is an Iterative Process

Alternative Formulation is a
“Systems Process” That Proceeds From
the General to the Detailed
Alternatives should initially be presented as
general concepts
Estimates of impacts on planning objectives
should be made
Infeasible alternatives should be discarded
Inferior alternatives should be identified
Promising alternatives should be analyzed in
greater detail
Alternative Formulation Requires
Creative thinking
Collaborative effort
Compromise
Vision
What is the best alternative you have developed
to a difficult problem?
What is Brainstorming?
An effective process for initial generation of alternatives
Encourages participants to freely offer suggestions
Forbids premature criticism and analysis
Requires participation of experts, managers and
stakeholders
Improves response via collective thought
Forces the examination of a wide variety of ideas
Helps assure that no options are overlooked
Shared Vision Models are Valuable
Tools in Alternative Formulation
Performance measures allow managers and
stakeholders to envision the impacts of
proposed actions
Simple representations of alternatives can be
developed to determine general trade-offs and
evaluate system behavior
Shared Vision Models are Valuable
Tools in Alternative Formulation
More detailed models can be used to perform
detailed analysis at the design level
Model use enhances understanding of system
sensitivities and promotes conceptualization of
new alternatives
Alternatives can be fine-tuned through
sensitivity analysis
Generating Alternatives Requires
Creativity*
An attitude that allows you to search for ideas
and manipulate your knowledge and
experience
Trying various approaches
Using impractical
(* von Oech 1990)
Obstacles to Creative Thinking
Whack’s Ten Mental Locks
1. “THE” right answer
2. That is not logical
3. Follow the rules
4. Be practical
5. Play is frivolous
6. That is not my area
7. Avoid ambiguity
8. Don’t be foolish
9. To err is wrong
10. I’m not creative
Adopt an Appropriate Attitude
Make a commitment to generate multiple
strategies
Adopt a questioning attitude
Don’t be afraid to fail
Create the Proper Environment
Advocate collaborative thought
Eliminate distractions
Provide support to bring ideas into action
Take Action
Solicit input from different perspectives
Ask “What If?”
Examine the value of existing constraints
Delay criticism
Alternative Evaluation
and Refinement
The Formulation Process:
Fine-tunes alternatives
Defines components completely
Uses different evaluation criteria in
different stages
A Phased Assessment of Impacts
Preliminary Screening Criteria
Completeness: all the required plan elements
are specified
Acceptability: decision criteria and planning
constraints are satisfied
A Phased Assessment of Impacts
Intermediate Screening Criteria
Effectiveness: planning objectives are
addressed
Detailed Assessment
Efficiency: a high ratio of plan outputs to plan
inputs
Activities in Detailed Evaluation
Risk assessment
Economic analysis (NED, RED,
Incremental Cost)
EQ and OSE account quantification
Activities in
Alternative Refinement
Alternative Refinement is a process of:
Specification - defining the details
Optimization - enhanced by the
understanding of system sensitivity
Summary
Alternative
formulation is an iterative cycle of
generating, screening, and refining alternatives that
proceeds at increasing levels of detail.
Creative
thinking promotes the identification of
effective and innovative solutions to planning problems.
Planning
Objectives, Metrics and Accounts are used to
assess the completeness, acceptability, effectiveness, and
efficiency of a proposed plan.
