What is an Implementation Plan? [& How to Do Yours Right] Project management doesn't exactly lend itself to freestyling. You can't really wing it and bank on your intuition to successfully guide you as you go. You have to put in a lot of thought, carefully plan, determine relevant metrics, and observe progress on an ongoing basis if you want your project to come to fruition. And you can't just trust your memory to address all those actions and elements. You need something known as an implementation plan — a document that covers most aspects of your project's blueprint and preferred trajectory.
