Just as a hearty salad can improve your personal health, robust processes can improve the health of an IT infrastructure. Seasoning your salad with the proper mixture of vinegar and oil makes the salad more appetizing, and hence more nutritious. Similarly, seasoning your infrastructure processes with the proper mixture of strategic and tactical orientations can make them more appealing, and hence more effective.
But just as saturating a salad with too much of either oil or vinegar can destroy its appeal and nourishment, too much orientation toward either strategic or tactical processes can undermine an infrastructure. A proper balance between strategic and tactical processes can improve both the long-term planning and the short-term operation of an infrastructure.
