In one of our advanced control engineering class, I learnt why naval ships are very rugged. Everything is designed in multiphase + backup. It is like having 5 hearts. Even if 2 are broken, can still switch to another heart. Everything is designed to have backups and bypass so they won't be stranded at sea. Designing infrastructures for Nigeria should be that way. We are always in a sea of problems. The economy is the wind and govt policies are sometimes the incoming torpedoes.
