Alternative Formulation is a “Systems Process” That Proceeds From
the General to the Detailed
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

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

SummarySummary
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.
