explain why is it essential that the objectives of an organization be verifiable.

A goal is your general intentions.
EX.. l wish l want l hope.
Objective can be measured and is
precise .

If an objective is impossible, it is needless to have it. And objective is objective; a goal is subjective--meaning that it is not influenced by irrationality & emotions. Goals carry emotions which may be wrought with irrationality since subjectivity gives one freedom to be whatever he wants regardless of physical boundaries.

In an organization the goals r stated in the Philosophy of the Organization. The Philosophy of an Organization is often broad & beautiful. But the objectives r stated in the Bylaws, etc.

Examples:
Goal: to make the world a better place by helping everyone on a come as u r basis.
Objective: To give legal advise to 400 low income people per year on divorce matters from January 15 - December 15, 2008.

An organization could not help everyone in the world; but if it set objectives on what it could do & work toward that goal, then it could chart its progress & be effective. An impossible objective would be useless; Like, a person, it finds what it can do & work towards doing it. For an organization to write down objectives that it couldn’t possibly obtain would be madness.

The Objective helps the organization complete their goal—philosophy. By the way, each viable organization has a Philosophy, usually stated somewhere. For example, when one set up a library, the first thing the creator does is define the philosophy of the Library. Then he/she sets out methods of making the philosophy real.—that is ways of implementing the objectives. This practice is why a libary is not a collection of books, etc. And, it is one of the characteristics which turn a cooperative into a legal entity that lives, not simply though its shareowners, but in itself.

For example

While playing football. U want to score a goal is the goal..Objective would be to win the match

Each one of us set our goals, to achieve the Objective.

Most of us, get educated to empower our self to get employment ( or Self Employment ), with objective to earn Bread respectably.

We further set our Goals, to gain education in particular field up to certain, level (like graduation, post graduation, etc.) or training in vocational course, to get employment.

Advertising, through a particular media is a Goal, with objective to do publicity of product(s), service(s), & the company which is Manufacturing & Marketing the product(s), or service(s),

With all the Best.
