Daryl Conner has studied and authored books about change and its effects. In his research he found that only one-third of strategic initiatives actually turn out exactly as designed. Human nature, production, and plenty of other factors will have an impact on the results and influence the original vision. You will also need to fix problems that crop up. This will lead to a different result that can range from slight to significant.

For example, when you go to a car show and look at the new vehicle designs, there are often significant differences between how the car was initially designed and what people are actually driving. Projects run into cost overruns and must be scaled back. As well, sometimes the technology changes so quickly that what we thought we were designing will be redundant by the time we finish unless we make changes as we go.
