In terms of technical leadership, what you are interested in? IBM invests enormous amounts of money in open source projects and IBM Research. And for the last 24 years straight, IBM has earned more patents than any other company (it’s not even close).
That's not a great measure of technical leadership. Shows they have good lawyers though!
I think this is definitely true. I also expected this was the case for Yahoo. In general, perks and management philosophies only change when things aren't going well. From what I can observe, IBM has been on a decade long crash course of cutting and squeezing to show increasing profits.
Working from home is great. You get more time in your day, you don't burn any fuel getting back and forth to work, everything costs you less, etc. It's win-win-win-everything.
If IBM can't measure productivity and/or motivate people, I'd say that's a symptom of poor management.
