A mission and vision is a filter against everything.
A set of values are the added armour.
Constraints are either created by the mission, vision and values, or are deemed as necessary to drive them forward. It works both ways.
Filters whittle down your choices and resources. Constraints will set your boundaries.
Filters are singular, constraints are multiple.
A personal mission to be a healthy and active high performer is a filter.
One of your constraints may be that you don’t drink.
Filters drives long-term behaviour, constraints drive the day-to-day.
At your workplace, the shared mission and vision may be to create sustainable financial solutions for working mothers. The filter.
One constraint may be that you only communicate with your clients by email. Or that you don’t advise on the stock market. Or that you don’t meet in person.
Some constraints are created automatically from your filter (i.e. working mothers only), some constraints are necessary to drive the filter forward.
