That PDF is now sent to his or her boss, who fills out the organisational details, and signs that part. Finally the PDF goes to HR or whoever who gives the final signature. Since all employees have signature cards (chips with PKCS signatures on them) the whole process get's safe, accountable and paper-free. In the past stuff like this required printing, hand-signing, scanning, sending, printing-again, ... you get the idea.

You can already create the forms with ConTeXt and then extend them with Acrobat - that’s at least a lot less work.

I’m not up-to-date WRT PDF specs, previously all the signature stuff wasn’t in a public spec. But if there exists a LaTeX package, it can’t be that hard any more.

I recently created forms for a kindergarten patron foundation - parents have to fill more than 50 pages of forms, each in two copies, for all the necessary details and responsibilities. Most of the fields are used several times (name and birthday of the child, name and address of the kindergarten etc.) Because it was easy, I made interactive forms and suggested to evaluate them with a script that transfers the data into a database. Unfortunately, the teachers seem to be computer illiterate, they want to fill out everything manually (or have the parents do it). Maybe they’re just sadomasochists.
