In this video, I'll show you how to write the overviews for the process diagrams. So you've seen this process diagram before when we wrote our introduction. So let's move straight to the overview. So here we have a numbered process diagram. This means that we have the number of stages, clearly listed out here as the numbers one, two, and three. So the first thing that you need to do when you're writing the overview for the process diagram is you need to list the number of steps in the first sentence.

So let's see what that looks like. Here's our first sentence. On the whole, it is clear that salmon go through a series of three stages to complete their lifecycle. So that's what we have to do in the first sentence, we have to describe the number of stages in the process. So when you have a numbered process, This diagram, this is very easy to do, because you can simply count the number of steps. In the next sentence, what you have to do is you have to describe the first stage of the process and the last stage of the process.

So, in this case, this here is the first stage of the process and here is the final stage. Now, I want you to note that even in the process diagrams, we do not mention any specific details, okay, so, you should not be mentioning any key details, similar to how you don't discuss any key numeric details in the trend graphs and comparative graphs. In the process diagrams, you have to do the same thing. You cannot discuss any specific details in the overview. We only discuss the specific details in paragraphs three and four. So, let's describe this first and final stage in our second sentence.

To this overview, so here it is. They initially hatch from eggs as tiny fish, and continue to develop into full sized adults over a number of years. So notice that here, we're just giving some basic information. We're saying that in the first stage, the salmon hatch from eggs as tiny fish. And then they develop over a number of years into full sized adults, which you can see in the final stage here. So that's all you have to talk about in the overview to a process diagram, just talk about the number of steps or stages in the first sentence, and then talk about the first and the final stage in the second sentence, and your overview is complete.

Let's look at our next example. This time, we have a process diagram which is unnumbered, meaning that we don't have the number of steps or stages clearly laid out For us. So what you have to do in this case is you simply have to count the number of steps or stages. So let's go ahead and count the number of steps in these diagrams. So here, we can see that in the first stage, limestone and clay, go through a Crusher, that's the first stage. In the next step, they go through a mixer.

Next, they pass through a rotating heater. Here we have a rotating heater. And finally, in the last stage, the limestone and clay go through a grinder, and that's when they get converted into cement. So if we were to count the number of steps here, we can see here is number one, here is number two, here is number three, and here is number four. So in our first process diagram, we have a total of four steps. Now let's go ahead and count The number of steps in our second process diagram.

So in this process diagram, we can see that there are four different ingredients. We have cement, water, sand, and gravel. And all four of these different ingredients go through a concrete mixer and they get blended up, they get mixed up. So here you can see that we actually only have one stage, only one process is happening here to produce concrete. So in our second process diagram, we only have one stage. So you may recall from our previous discussion, that the first thing you need to describe in the overview of a process diagram is the number of steps or stages.

The next thing that you have to describe in the overview is you have to describe the starting point of the process and the ending point of a process. So let's take a look at the starting and the ending point of cement production. So here we have the starting point, limestone and play, go through a Crusher. That's the first step of the process. And here we have the final step of the process. The final step is that this cement is put into bags.

Again, you should not be describing any specific details or numbers in your overview. Now, let's take a look at the starting point and the ending point for concrete production. Here we can see that this is the first step to concrete production. And this is the last step. So all you have to do in the overview, is you have to describe these two points, the starting and the ending. I want you to note that we're not particularly looking at the steps here.

So when we look at the starting and ending points in a process, we're not necessarily looking For the stages, so we're not looking for the first stage and the last stage. Instead, we're just seeing what's at the beginning of the process, and what's at the end of the process. So here, in the beginning of the process, we have a bunch of ingredients. Notice that this is not a stage. However, at the end of our process here, we do have a stage, which is the only stage in this process. So in the overview, when we're describing concrete production, we're going to be talking about these two points, the beginning and the ending.

So let's go ahead and take a look at the first sentence to our overview. Overall, limestone and clay pass through four stages before they are turned into cement, and bad for us. So in our first sentence to our overview, we are describing the first process diagram we're saying That limestone and clay pass through these four stages before they are bagged for us. So what we've done in this overview is, first of all, we have described the number of stages in the first process. Also, we have described the starting point of the process and the ending point of the process. In the next sentence, we're going to describe concrete production.

So here's our next sentence. Producing concrete however, is a simple one step process, wherein various substances are blended in a concrete mixer. So in this sentence, we have given some very basic information. First of all, we've said that there's only one step to this process. Next, we've described that there are a number of ingredients which are mixed into a concrete mixer. So here we've given some very basic basic information about this process diagram.

So now that we've discussed the number of steps and stages in both the process diagrams, and we've also given information about the starting and the ending points of our process, our overview is now complete. So that concludes this video. I'll see you in the next video, in which we're going to talk about how to write the overviews for map questions.
