A circular, pie-chart style diagram. The circle has an outer ring comprising three segments. The inner circle has six segments. The first outer segment is in colour green and says understand. This correlates with two inner segments, also in green, which say emphasise and define. The next outer segment is in red and says explore. This correlates with two inner segments saying ideate and prototype. The last outer segment is in blue and says materialise. It correlates with the inner segments saying test and implement. At the centre there is core circle that says monitoring and evaluation. Arrows point outwards from this core to the five segments emphasise, define, ideate, prototype and test indicating learning and an arrow points inwards to each of these segments indicating learning. In the sixth segment, implement, the learning arrow points outwards from the core and the intervention arrow points inwards into the core.
