Breaking down silos is a frequent organizational mantra. However, if taken to the extreme, you end up with a pile of rubble and scavengers making off with your grain.
The simple truth of the matter is that no organization can be made perfect, they all have their inefficiencies, politics and barriers. Sometimes the more effective approach is to bridge silos rather than break them down. You are much less likely to bring the whole edifice down on your head if you focus on punching strategic holes in the towers and connecting them rather than trying to take on the entire power structure.
Sometimes the silo is more powerful than you. But almost any organizational silo can be pierced by an intrepid orgpreneur.
Build these bridges based on creating results, getting things done, routing around office politics that have things gummed up. You’ll soon be known as the person who gets it done without trying to reinvent the organization first.
