Abstract
OBJECTIVE: To introduce a new graphical tool that improves the process of making decisions about method performance. DATA SOURCES: Scientific literature, mathematical models, and the author's experience. STUDY SELECTION: Not applicable. DATA EXTRACTION: Not applicable. DATA SYNTHESIS: Relationship to charts of operating specifications (OPSpecs charts) provides guidance for classification of performance as poor, marginal, good, or excellent. CONCLUSION: Objective decisions on the performance of methods can be made quickly and easily with the aid of a Method Evaluation Decision Chart.
