Are you considering connecting your systems to remove that double data entry overhead?  Where do you start?

The most logical starting place is what data does the receiving system need that the sending system can deliver.  Break down the low level details fields and perform a mapping exercise to determine what type of programming is required. 

I enjoyed the content about considering human factors as it applies
to application data interpretation by different sets of users. It’s a
valid insight that I had not considered.

The area I would add is doing formal requirements capture. Writing
down requirements and giving them back to the business owner or
other customer, will help smoke out interpretation challenges as well.
