Based on literature, a theoretical model was developed for viable performance consisting of eight constructs whilst the trust model of Martins (2000) was used to measure four organisational trust constructs. Exploratory factor analysis was used to extract the constructs, and structural equation modelling was employed to validate the models against the data. An empirical model for viable performance resulted in a solution with seven constructs and organisational trust with five constructs. The two empirical models were unified into a model of viable performance and trust resulting in a measurement model where all 12 constructs were shown. Significant levels of internal consistency were measured. The resulting measurement model was tested for group differences, and no significant differences were found, indicating that the assessment can be used across different groups. It was concluded that the aim to construct and test an integrated and comprehensive theoretical framework of viable performance and trust was achieved and the resulting Viable Performances and Trust Indicator (VPTI) was validated as an assessment to be used across groups. Organisations can thus use the framework and VPTI assessment tool with confidence to assess performance and trust across different biographical groups. Future researchers can build on this exploratory study to refine the scales and apply the measurement model within the wider context of South Africa or as a globally accepted model. / IndustriaI and Organisational Psychology / D.
