If you have portfolio ministries, you have multiple purposes, visions and goals for each portfolio. These are all things that you need to hold in tension with each other.
The wrong approach is to try to find a compromise between those purposes, visions and goals; ultimately reducing them to vague fluff.
Of course you will need to make actual daily decisions and choose one thing or another. But that’s the point… If you keep those purposes really crystal clear then you’ll be best placed to make the best decision when the time comes.
If you have portfolio managers this means they need to fight and trust.
