A technological innovation disrupts. Before the 2000s, Dell was a market leader and enjoyed massive profit margins. After that, Apple introduced tablets which ate into the market share of laptops and computers.
It may not be easy to spot trends ahead of time, but leaders must try to navigate hints and signals. Nokia didn’t act on the series of patents that Apple was filing secretly over the years.
You need to find talent that can spot developments early in an industry, and develop a taste for cross sector analysis. Disrupt happens when one industry crosses into another. Think about the implications of mobile phone technology and the financial sector. Major changes to take place soon. The same will happen in other industries when sectors merge.
