So in the last step of, the sixth step of calculate a line of balance and draw a line of balance is to draw the line of balance diagram. And here, I put a quick example, if we have three processes for each line from A, B, and C, highlighting a process or a construction activity. The last three column we have in this table, column number 7, 8, and 9, I put them here because these going to help us with drawing the line of balance. Instead of having production rate, as I explained, you can just highlight with a bar. So the first one, the line A or the bar A here, it shows that the thickness of the bar, would be the activity duration for one project. Or I'm sorry for one unit or one section, I extend also here in activity B. So the longer each section, the thicker will be your bar on each of the processes or the construction activities you're going to draw their line or their production line. Now column number 8, as I mentioned, it is the time from start on first unit, to time of the start on last unit. So, if this is A, we have the first unit will be here, and then there will be the second unit, the third, the fourth, the fifth, all the way could be to the 13 unit here. So the last, let me draw it quickly here. So, A would be if there is, this is the time and this is the production, we might have sections like that. All the way to the last section if we can have it maybe 13 to be consistent with our previous example. So in this case, these sections then we will draw them as a line or process A. And the beginning of the first section and the beginning of the 13th or the last section it will be number 8 here or column number 8 and the same will go for B and C. So each column or each bar or each line production line is actually small bars highlighting each section you have in your repetitive project. For our approximation, we just draw a line instead of small bar charts highlighting each section when starting and when ending. So moving forward on this example. We have also identified the, for, let's say activity C, or process C. The beginning which will be here to the beginning of the last unit, which will be here, the one here. And that will be also 8, or column 8. So in this case you go to see from the table that you just developed or calculated the numbers for, look at activity C or process C, go to column number 8. You will find this number here. Now moving forward, as I mentioned there will be a lag time or a buffer time between each two processes, production lines or curves. I put here a rule of thumb, if next activity, let's say between A and B here, for example, if the next activity will be faster which mean have a higher R. And the R we find it from the actual output rate here, column number 6. Which is Ra, if next activity will be faster, higher R, there will be faster the production, it will be more steeper, what's going to happen? The buffer will then be on the top of the two activities, as we mentioned here, number 9 because you don't want to intersect it. So you keep a buffer in the top. Now, between B and C, C is faster than B. In this case, if we have the buffer on the top, what going to happen? We're going to move see all the way, and what going to happen? There will be an intersection. So, that's why we keep the buffer in the bottom. That's what we mention here as vice versa. If the next activity will be slower, So you have low amount or number of RA than the following one then the buffer will be at the bottom. As we can see from B and C the buffer we put it here. The number 7, 8, 9 refers to the, of course, the columns 7, 8, and 9 here. So this is some tips, what I'm giving you when you draw a line of balance, and we will go through a detailed example.
