The strategy implementation tool used to determine what actions are going to be taken, by whom, during what time frame, and with what expected results is called a(n)?

It's called an action plan

As long as we could organize what actions that are going to be taken, when, where, and what could we achieve by that action, basically we can use anything as an action plan

Action plan is different from a to - do list because an action plan is goal oriented. As long as the goal already accomplished, we don't necessarily have to follow the remaining steps
