Let's say we work at a bakery. There are folks who bake cakes and those who bake brownies. They don't switch roles cos there's not enough time for them to learn one another's roles. Then one day, an order comes in for a brownie and lands in the lap of a cake-baker accidentally. The cake-baker got so intrigued he forgot about baking cakes and started reading up (not even trying hands-on) to bake brownies. Now the cake orders pile up and overflow to the brownie-bakers. Unfortunately, brownie-bakers aren't able to handle cakes. Confusion ensues and unhappy customers wait. No cake, no brownie.

There you have it... a summary of my team meeting.
