Working in Environmental areas you become aware of water, but the basics still apply. If you pollute a stream of water at the source every inch of the water down stream could suffer from the pollution at the source. To fix the problem say 15 miles downstream is to allow for 15 miles of stream to remain polluted. If you really want to solve the problem you solve it for all the miles of the stream not just for some of the stream. Are data streams that much different? Fix it at the source, fix it early, and fix it right, then at all points along the way, everything is great.

Sales people sell product, they are not producers of product. We hire them to sell not to be computer or database experts. We need their feedback and assistance defining the market, be we do not need them to architect or code systems. Do they take the high tech coders out to sell product? They cringe at the idea. So why do they feel they can do all things IT? Odd bunch of ducks those sales folks. 🙂
