Based on whether the IT is doing the right thing (aligned with business goals) and whether it is doing it right (effective), the researchers divided the companies in four groups:
The figures in the picture are comparing to the average and over three years - so, for example, the group that has IT aligned with the business but not effective has 14% less sales growth than the average of all surveyed companies, but they spend 13% more than the average on the IT. On another hand, the group that has a mismatch in what IT does and what the business wants, but with effective IT, spends 15% less on IT then average but sees 11% more sales growth than the average over three years.
A very important note from Allan’s talk is that the transition from the top-left corner into the top-right corner is virtually impossible, unlike the transition from the bottom right corner into the top-right corner. Doing the wrong thing but doing it right turns out to be better than doing the right thing poorly.
