Some how, I am getting impressions of HP's former CEO Carly Florina, while reading this article. Hope it won't end like that.
It appears Marissa Mayer is in hurry to prove something but without proper strategy. She is sort of mixing Apple's Steve Jobs way, netflix way, Google's data obsessive ways to somehow create some recipe for success.
I feel she has to cool down and make some original recipe rather than mixing from various other companies.Wall street, Yahoo Board and investors need to be told that turnaround may take at least five years and there should be no hurry in between just like HP's current CEO Meg Whitman did, irrespective of consequences. This can give her peace of mind and helps in creating a better strategy. It appears, she wants to rush but do not know where to and meanwhile falling. She has to slow down and rethink.
Also, this article can be condensed. It lists about yahoo from its start to previous CEO's, her hiring ...etc. Yahoo's past before Mayer may be irrelevant in the context of this article.If needed, URL to past article may be sufficient.
