Report ba to?
Product Manager number 1.
Actually parang nabigay na ang explanation mismo sa number 1 on how to develop product plan, kasi binigay na ang sagot sa "how". So all you need is to deliberate it more clearly,
"See that they are implemented" - practically as a manager your work is to give orders to your people, so when you give orders, you must monitor them if they do their work, since if they fail to do their work , titingnan mo kung lahat ba ng utos mo ay naimplement, lahat ba ay nagawa.
"Monitor results" - in connection with the first step, since you monitor your people, syempre you also monitored the result of your plan and their works, and its important so that you can take an action ("take corrective action") if your plan need to improvised or your plan is success.
Tips lang ts, when youre reporting a topic, always give an example after you explain.
