How successful these innovations will be is anyone’s guess, but what is always known is this: Some parts of these new initiatives will work some of the time with some of the people; other parts will work barely at all. Some people will experience success, and others will be frustrated and fail. Almost never will any of these changes work perfectly
well with everyone. On the other hand, it is also unlikely that these changes will be a total failure—someone, somehow, will make at least some of them work. Those whose job it is to make them work have a daunting challenge. They must have some ways of finding out—as quickly and easily as possible—which things are working and which are not; what parts of new innovations are working well enough to be left alone, which need revision, and which should be abandoned.
