There is no single honest answer, timelines range from a few weeks for a simple, low risk configured tool to many months for a complex, high risk custom system. What actually drives the timeline is less about the software itself and more about how much of the evidence has to be assembled by hand.
A system's risk category sets the depth of testing required, but the bigger swing factor in practice is process. Teams reconstructing evidence from scattered emails, chat threads, and someone's memory of what happened take far longer than teams whose evidence was captured as the work happened.
Waiting on evidence that exists but is not filed anywhere organized. Chasing down an approver who is unavailable. Reconciling a requirement document that no longer matches what was actually built. None of these are inherent to validation itself, they are process gaps that compound under deadline pressure.
Rather than asking how long CSV takes in the abstract, ask how much of your evidence already exists in a usable, traceable form at the moment you start compiling a release package. That single question predicts timeline far better than the system's complexity alone.
A short walkthrough of how GxPForge keeps traceability current as your team works, instead of reconstructing it before a release.
