Vector and Triangular Representations of Project Estimation Uncertainty: Effect of Gender on Usability

The paper proposes a new visualisation in the form of vectors not-fully-known quantitative features. proposal is put context project defining and planning importance for decision making. approach empirically compared with already known utilizing membership functions triangular fuzzy numbers. designed conducted experiment was aimed at evaluating usability according to ISO 9241–11. Overall 76 subjects performed 72 experimental conditions assess effectiveness uncertainty conveyance. Efficiency satisfaction were examined by participants subjective assessment appropriate statements. results show that proposed may constitute significant alternative known, triangle-based visualisation. emphasizes potential advantages representation management other areas.
