The median implementation time for projects is just under four months. It is well worth remembering that larger or more complex projects are highly likely to take longer than the median time. We also find that project implementation time is a significant source of business user satisfaction. Good satisfaction with the timeframe of projects is well over 60 percent, and poor satisfaction with the timeframe was a tiny minority.
How long did it take to implement the BI aspect of the application from software purchase to initial rollout? (n=2,198)
Project timeframes for BI measured in years rather than months clearly do still exist, but the size and complexity of such projects is sometimes astronomical, involving multiple large organizations; changes in regulatory or other standards that must be observed; large, numerous, and sometimes very dirty data sources; internationalization of results and interfaces, and other complexities besides. In these cases, a long project is likely. It will be interesting to see in years to come if the growing adoption of an agile technology implementation methodology reduces the median and ‘long’ times further.
One final view of the impact of implementation times is through the lens of the Business Benefit Index (BBI):
Business Benefit Index analyzed by implementation time (n= 2198)
The chart shows that there is a fair spread of BBI scores. Decent benefits are obtained by projects with the longest implementation times, but the score increases by around 50 percent for the shortest implementation times.
