Try to learn one programming language. Old or new, take your pick. Discover its syntax and flow and usage and remember how it feels to code. See if you can create a basic application, add features to it containing logic and conditions, manipulate information according to whatever you desire. Be aware of how difficult it is to create something that flawlessly works based on an idea. Keep in mind how much time it takes to create a functioning button, to make a working process from start to finish, to display the right information based on data.
Then recall how fast your developers create and change code in order to follow agreed project business rules. If somehow a specific programming task is taking a while to finish, often there’s a good reason. And if you know how it feels to code, you’ll understand that software development (as is with all high-quality creative work) requires a bit of time.
