Have you tested your strategy lately? That's the question posed by Chris Bradley, Martin Hirt, and Sven Smit on the McKinsey Quarterly website.
The authors say the basic principles of a good strategy can often get obscured. Sometimes there is the distraction of pursuing the "next new thing".
In other instances, the true purpose of the strategy gets lost in "torrents of data, reams of analysis, and piles of documents that can be more distracting than enlightening".
