BlackBerry to cut up to 40 percent of employees

Meanwhile, I'd be more worried if I were Apple. It will be hard for them to keep-up with the innovation. Especially since there is a flood of new OSes coming like Ubuntu, Tizen, Firefox and more flexible HW platforms.

Nokia took the competition seriously, but made a single fatal error: it tried to evolve its low end platform into its high end platform. While that strategy makes complete sense in 90% of cases for market innovation, in the mobile phone industry--which, it turns out, was going through revolution--Nokia should have done the opposite. People often forget that Nokia still controls more than 70% of the worldwide phone market, and controlled vastly more of it in the mid-2000's. In 2007, they had no idea that 90% of industry profits would come from the 30% of the market that they were not focusing on.

You can't really fault them for that, because strategically it makes perfect sense. They regarded the competition seriously but had a flawed approach/response.

That being said, they had a bunch of half-assed hedges against their fatal strategy, like high-ish end platforms such as Maemo, Symbian's advanced versions, etc.., but in fast moving markets with extraordinarily complicated infrastructure/platforms, this approach does not work. You can half-ass evolution, but you have to full-ass revolution.

They realized this mistake fairly early on, but by then it was too late to develop a platform, and full-assing it would have put the company's core competencies at huge risk. So Kallasvuo was fired, Elop was hired, the company moved in with Microsoft, and, eventually, they married.

when a company is of a certain size and top management is making millions, radical change becomes impossible

BB is dying, because it needed a radical change, but top management, I think, were too afraid to act on it

This is even true of lower levels inside organization, managers accept defeat rather than challenge it by requesting a radical change

To add more, I believe manager prefer to fail for doing small changes, rather than fail .. because they took on radical changes ...

they should have gone radical, but they went incremental, because its better for management to fail that way

If you do, then you are very naive. Yet you don't hear men whining about about a gender imbalance because women get up to just as much objectification. There are other reasons why there's an imbalance, if you look at other factors, ethnicity, for example, you'll find the same imbalance, and for the same reasons.
