Goal, purpose and ideal scene sound alike, and they are not the same thing. A goal is the big, long-range direction of the business. A purpose is smaller and belongs to one particular activity. An ideal scene is that purpose worded sharply enough that it describes a situation. Mix the three up and you end up with a plan that has nothing to close.
The trap in the two words
In everyday business English, goal and purpose get used almost interchangeably. And when people do separate them, they usually treat purpose as the loftier one: the grand reason the business exists, the line on the mission statement.
On the ladder the booklet teaches, the one that connects the big ambition for the business with what gets done this week, it's the other way round. The goal is the big, very long-range one. The purpose is the smaller one, tied to a specific activity. The source defines a purpose as:
“the lesser goal applying to specific activities or subjects”
Suppose a gift shop wants to be the leading shop in the area for corporate event gifts. That's the goal. Beneath it sits a purpose: every corporate client gets a gift that feels chosen especially for them. It's narrower, and it serves the goal.
Or a garage that wants to be a garage people trust. The purpose beneath that is that every customer knows what the repair will cost before work begins. One points the way, the other does the work.
This mix-up doesn't stay in the vocabulary. If your purpose reads like something you'd hang on the wall and leave there for years, it's really a goal. Everything you build under it will rest on something too broad to work on.
One goal, several purposes
A single goal usually produces several purposes, not just one. The reason is simple: a goal covers several directions, and each direction needs a purpose of its own.
Take the garage people trust again. It rests on three different things: transparent pricing, being on time, and repairs that don't come back. Three directions, so three purposes.
Now the opposite case. Suppose a clinic owner writes a single purpose: excellent service. After a while she realizes it isn't a purpose at all, just another name for the goal. Once she splits it into three concrete purposes, everything beneath them changes.
If you have a goal and exactly one purpose, there are two possibilities. Either the goal is smaller than you assumed, or the purpose is phrased much too widely.
The ideal scene is the purpose, stated as a situation
The first thing to check on any plan is whether it contains a clear statement of the purpose. And when that statement really is clear, something convenient happens: it already describes how things will look once the purpose is reached.
That is the ideal scene: the picture of things once the purpose has been reached in full. Next to it stands the existing scene: how things look right now. Everything the plan has to close is the gap between the two.
So there's no need to write the ideal scene twice, because a sharply worded purpose already is the scene. When the gift shop writes that every corporate client receives a gift that feels specially chosen, it has described exactly the situation it wants to see.
Suppose the garage looks at how it receives vehicles. In the ideal scene, every car has an approved quote no later than two hours after it arrives. In the existing scene it takes anywhere from two hours to two days, depending on who's on shift. That's a clear gap, and it can be worked on.
What doesn't work is better service. That isn't an ideal scene, because there's no way to tell when you've arrived. And if you can't tell, there's no measurable gap either. When the scene is worded properly, though, the number that tracks it almost writes itself. It simply measures how far you still are from it.
A stopped purpose
Purposes have a problem that task lists never have. In the source's words:
“purposes fail often and come to a stop”
And a stopped purpose doesn't disappear. It may later be played out in behavior without anyone noticing. Say you once tried to open a new sales channel and got burned. Chances are you no longer approach the subject with a clear head. You come at it through that old stop: either you keep away from it, or you overdo it in the other direction.
Suppose an owner once tried to hire someone and it went badly. Ever since, he doesn't believe in employees. Nobody ever looked at the purpose again. It simply stopped, and stayed stuck there.
That isn't a character flaw. It's the predictable behavior of a stopped purpose, and recognizing it is enough to start taking it apart. If there's a subject you avoid altogether, there's usually no decision behind it. There's a scar.
What the booklet has on this
This is the third chapter of From Goal to Target, and it closes with two exercises: build it, and analyse. The chapters after it cover policy, the bridge from the existing scene to the ideal one, and six kinds of targets.
A goal gives you a direction. A purpose worded cleanly gives you a place where you can check whether you've arrived.
