Traditional IRT systems that rely on programmable implementation do not offer the ability to show the system as it is being built. With configurable systems like Calyx IRT, however, the team can show the system as it is being configured. The system itself becomes the center of specification discussions, instead of focusing on theoretical concepts that often do not mean much to trial teams.
With the right underlying architecture, the IRT vendor can even give the study team access to the system during the setup phase. Study teams can look around the system in their own time, allowing them to anticipate the alignment of system functionalities with end-user workflows, system understanding by non-expert users, and appropriate language usage.
