Duplicate work required by sponsors - whyyy?

Recently, I’ve seen an uptick in sponsors requiring deviations to be entered in the EDC or a sponsor CTMS, when we have a CTMS that we can generate a log from. I’m told that the sponsor won’t back down when we push back on this, which seems ridiculous.

Additionally, I saw a study recently while working with a staff member where they require the site to enter data from central lab results. That seems unnecessary but I’m wondering if there’s a good reason.

Sponsors talk about site engagement but this seems so counterproductive. What am I not seeing?
