I just came back from
While Ingo and I were visiting the area of “Cape Point” and “
As we all know, sailing along the coast of
They decided to build it on Cape Point because it can be seen from far away. The lighthouse was built in 1860 and the white flashing light of 2000 candlepower could be seen by ships 67 kilometers out of sea! From an engineering perspective, this was great work. But in reality, the lighthouse proved to be ineffective as it was often covered by cloud and mist. At this point one important question arises. The scenario that makes a lighthouse most valuable is navigating in bad weather and poor visibility. By solely focusing on the candlepower and the ability to be seen as far as possible, the decision to build the lighthouse on the highest point sounded brilliant. In reality, it was very ineffective as it didn’t support the most important scenario: navigating in bad conditions! After the wreck of the Portuguese liner “
I think this is a great example why scenario driven design approaches makes so much sense and can prevent our systems from great but useless features!
