My experience is that you can often find low hanging fruit, relatively easy changes that will have high impact. For example, I've created checklists for some of the processes that we do often, especially when it involves coordinating with a customer. Creating the initial version maybe required a few hours, but since then has been used 100's of times to shave 1-2 weeks off of work and reduce errors/surprises.

Another example is really basic automation. You probably have people/teams around you that are not developers. They probably are spending time doing really basic repetitive tasks. One team I work with regularly would take a spreadsheet, then for each row create a folder and docs in Google Drive. I wrote them a Google Apps script that could do the task with a click. Not quite as impactful as the checklists, but each script like that saves someone a couple days a year.
