So perhaps the Blackberry maker RIM's new CEO is getting a lesson in the value of being careful fairly early on his his stint at the smartphone specialist.
Thorsten Heins responded to a $125m loss pointing out that it made sense to refocus the business on its core market in the corporate market.
That led to headlines across the board about a decision being made to exit the consumer business. It has also led this afternoon to some serious backpedalling by RIM, which is now doing everything to stress that it is not leaving the consumer business.
But as HP found out when its former CEO Leo Apotheker said it would consider exiting the PC market, just a few words can do a lot of damage.
RIM has a heap of problems at the moment trying to regain ground lost to Apple and other rivals and although you can see the sense in what the CEO is saying, the way he expressed himself has caused more issues for the management and vendor's channel to deal with.
