Principle 9 of ICH E6(R3) addresses this fundamental question: What does it take to produce reliable results?

The answer, it turns out, is not simply "be careful" or "follow procedures." Reliability requires integrated systems that capture information appropriately, protect data integrity throughout its lifecycle, and make results accessible to those who need them. It requires proportionate attention—not equal attention to everything, but focused attention on what matters most. And in an era where trials increasingly involve computerized systems, decentralized elements, and global data flows, reliability requires deliberate design.

This lesson examines Principle 9 and its sub-principles, which together establish the framework for generating trial results that regulators, clinicians, and patients can trust.
