Why should short term goals and long term goals in an organisation go hand in hand?

Achievement of any goals, whether short-term or long-term, is dependent on our actions in the present. Whatever we did yesterday cannot be changed. And, as they say "tomorrow never comes".

If we have some long-terms goals, we have to start moving towards that goal immediately. We cannot wait for the long-term to become short-term before we start working towards achievement of long-term and in the meantime work on things unrelated to the long term goals.

Actually we need have long-term goals because many goal require preparation and efforts over a long period towards achievement of the goals. And all the action that we need to take over a long term period can be taken more efficiently when the route to achievement of long term goal is well charted out and translated into short-term plans for the action to be taken, or route to be covered, in immediately following short term period. Thus I will that short-term plan and goals have to, not only go hand in hand with long-term plans and goals, but actually must be based on them.
