Text Box: Page # Text Box: Each knowledge source provides valuable insight, yet each has gaps, biases, and other possibilities for imperfection. Ventana triangulates among the three sources by cross-checking to identify discrepancies, finding the source of discrepancies with Vensim's Causal Tracing® technology, and resolving them. Combining the three sources through triangulation produces a fuller, more accurate picture than can be obtained from any one or two sources alone, and Ventana's tools make triangulation fast and efficient.
