It was hard to get all the company to use it. If you use it just for small subset than it is not that valuable.

Say you are tracking work done in vineyard, but nothing else. Then your calculation of price of produce is off, because you havent add the price of input. There are multiple roles in the company and they are usualy using they own systems for reporting.

Also quite a lot of production tracking have to be done on paper using special notepad with marked pages (another funny story) and people dont want to do this bookkeeping twice.
