In my lab experience, electronic lab notebooks were incredibly bloated, slow, and buggy to the point of being unusable. I’m most familiar with what was in place at Merck about 8 years ago: ELN (Electronic Lab Notebook). I agree with comments that the countersignature is both lax and absolutely necessarily from a records perspective. Most importantly, building a new lab notebook system would require importing data from whatever it is you’d be attempting to displace. Lab notebooks have significant roles in IP disputes, and it would be critical that the contents and timestamps are preserved.
To underscore how terrible ELN was at our site, many managers instructed their reports to keep traditional paper notebooks, photograph each page, and upload to an ELN entry. Countersignatures were then performed on the ELN platform. This was at a relatively small Merck site, and maybe the issue wasn’t as pervasive elsewhere.
