    Global Framework

    We defined cross-product priorities by creating an audit of user flows, features, common components, and templates to ensure that our system would be scalable across the entire suite. After completing that holistic exercise through user interviews, stakeholder workshops, and product research, we focused on re-defining 3 of the most used applications within ONESOURCE– ONESOURCE Tax Provision (OTP), ONESOURCE Income Tax (OIT), and Work Flow Manager.

      For the vision of ONESOURCE Income Tax and Tax Provision, we wanted to make sure preparers and reviewers would be able to easily navigate between binders, entities, and data sheets. For managers, we wanted to make sure they could easily track updates to reports and approve of final deliverables.
