Figure 3 At a distance, but how?

The image consists of a big frame that covers the lower two thirds of the image. In this frame there are two rows, the first one contains three bubbles, the second one four boxes. Above the big frame there are two bubbles.
In the upper left corner of the image the first bubble above the frame reads "project". From here an arrow points down towards the first bubble in the frame, which says "unit 1". From here an arrow points down to the first box on the left which reads "teaching message". From here an arrow points right to the second box which reads "application". From here an arrow points right to the third box which reads "Test". From this box two arrows depart: one reads "yes" and points straight up towards the second bubble reading "unit 2"; the other one reads "no" and points right, towards the fourth box reading "compensation". From this fourth box an arrow points up to the left toward the second bubble reading "unit 2".
From bubble "unit 2" an arrow points right to the third bubble, reading "unit n". From this bubble an arrow points up, towards the right bubble above the big frame, this bubble reads "objectives". From here an arrow points to the left bubble above the frame reading "project". Thus the circle is closed.
