Biggest waste not to duplicate, but repeated construction. In the early on-line a new service is often in addition to the data can be reused, the service can not be reused. In fact, the reuse of data services than reuse more benefits, but the raw data of production, service contains logic, is a factory processing plant, if the same process can be replicated, it will bring production efficiency improved significantly.
Building from the production model of the system upgrade to the operating model type, model upgrading from version to iterative model. Operational biggest advantage is that all models have been accumulated precipitation, while the production model because 10% of the difference between 100% and re-construction of the system. Every time a new story, a new logic, new code, and these are people from several brain. Operational logic model comes from numerous customers, suppliers mind, engineers, and after continuous accumulation, then the gap is obvious.
Not only companies, but also a personal Operational model of thinking. Often hear people complain that there is no precipitation around, largely because operators did not mind, there is no continuity of work, difficulties like starting from scratch, in the end futile. Like a lot of dug wells, but they did not see because the depth is not enough water.
