This chart is made up of small blocks or bricks, each representing 1% of target fulfilment. This means that if 19% of the target is completed, exactly 19 bricks are coloured. If the target is exceeded by 122%, 122 bricks are coloured. The bricks are first arranged horizontally up to a certain number (e.g. ten), then a new row is started above the previous one with space for the same number of bricks, and so on. The exact progress is shown as a number on top of every ‘brick container’,
In order to help interpret successful containers at a glance, a target line or a different colour for bricks 1 to 100 can be useful.
Speaking of bricks, let's have a look at a construction-related example. A property developer has a network of sales outlets across the country, each assigned to individual regions. Each region has a sales target for the quarter. The completion of the target means 100%.
As you can see in the chart above, three regions met their sales targets. In the southern region, sales exceeded the target by 48 percentage points, which is a very good outcome. The target was not met in the northern and western regions. For a manager, the information presented this way is a quick and clear way of finding which regions met their business goals and which did not.
