Answer to Question 2

Data, or the analysis of the data, may hide productivity gains. In service industries, such as finance or health-care delivery, it is more difficult to define what the products are, how they change in quality, and how they may be related to corresponding benefits and costs. EC productivity gains in certain areas of the company may be offset by losses in other areas. For example, increased online sales may decrease offline sales, a situation known as cannibalism. The results of any investment justification depend on what is actually measured. To assess the benefits of EC investment, one should look at productivity improvement in the area where the EC project was installed. However, productivity increase may not necessarily be a profitable improvement if there are losses in other areas. Many EC investments take five to six years to show significant positive results, but many studies do not wait that long to measure productivity changes.
