The reason that these approaches do not work is simple; any organisation, be it one person, a small team, a division or even an entire company can only focus on doing 2 or 3 things at once. Any more than that and focus gets too diffuse. With a lack of focus comes a lack of progress. Then one thing leads to another and none of the “ten key priorities” gets done.
A much better approach is to focus on doing two or three things. Get them in and running then pick another two or three things to focus on. In no time at all you will have all ten key changes made in your organisation.
It seems that recent research supports this approach. Today’s Harvard Business Review daily stat is that “Fewer Strategic Priorities Is Better.” Executives in firms that have fewer (one to three) strategic priorities “were the most likely to say that their companies have above-average profitability and growth.”
So how many things are you trying to do today? Maybe you should prioritise your list and get the top few done first.
