That's not procrastination, procrastination is when you avoid completing a task even though it doesn't benefit you to avoid completing it. For example, if a feature is supposed to ship in 3 weeks and you spend all 3 weeks "researching" libraries and on the last day you write some really bad code with no tests, that's procrastination. If you had just spent all 3 weeks writing the code and iterating on it using the tools you know you would have completed the task but you avoided completing the task for ____ psychological reason. A better name for procrastination is "task avoidance."

There's a more in-depth coverage of this in the book "Still Procrastinating" by Joseph R Ferrari (the top researcher on procrastination).
