Decision-making tools vary in sophistication and in their applicability to some types of decisions.  The Fuller Triangle (FT) method is relatively simple; however, this comes with a tradeoff.  Similar to Analytic Hierarchy Process (AHP), presented in Vol. III (6May 2020) of this series, but less rigorous, FT may be less suitable to highly consequential or complex decisions.
            Multicriteria analysis (MCA) tools facilitate organization of decision information for several alternatives and attributes.  When the rigor of a complex method is not required and a decision is needed quickly, FT may be an excellent compromise.  In this installment of Making Decisions, the Fuller Triangle is presented, including some comparisons to AHP to facilitate selection of a decision-making aid.

            Assessments of a lighting system installation is necessary to determine its compatibility with shifting or evolving requirements.  A lighting system can be evaluated by direct measurement, calculation of theoretical values, or simulation of the space in software.  Each has its strengths and weaknesses; the choice of method to be employed depends on the status of the installation, objectives of the assessment, and available resources.
            This installment of the series provides an introduction to each type of assessment.  These methods are not mutually exclusive; the most useful evaluation may be obtained by blending methods.  The presentation of concepts is kept brief to maintain a manageable scope in the series.
