5. CONTRIBUTIONS AND FUTURE RESEARCH
5.1 Theoretical Contributions
The purpose of the study was to empirically test several hypotheses advanced in the literature regarding strategic audit planning and audit performance by using environment uncertainty and time pressure as a moderator and audit judgment and quality as mediators.

Third, our findings provide further insight about the relationship between time pressure and audit judgment and quality. In the future, research should add other moderator such as task environment, ethics, client’s relationship, etc. to audit judgment and quality. Final, this study makes more contributions to the theoretical field by positing the audit judgment and quality, generally, as only dependent variables, as both antecedent and mediator variables.
