I was dealing with the same issue not long ago. I recommend that you start the way I did — look for annoying and time-consuming tasks that you can remove or automate to help your whole team be more productive. These changes will not only help your team waste less time, but they will also help morale. There’s this notion around that people don’t like to work, and that may be true, but the fact is that people enjoy pointless and repetitive tasks even less.
The good news is that automating tasks has never been easier. There are some very specific automation tools in the market today, as evidenced by this website for a door manufacturing software.
Figuring out which tasks to automate first is a little trickier. You can ask your team which tasks they feel are a waste of time, but if you are looking for precise results, the best option is to install time tracking software on office computers.
