The challenges that we have in the engineering world vary to some degree from one particular engineering discipline to the next because they're different work environments from one engineering discipline to the next. As an example, in biomedical and environmental engineering fields there are huge numbers of women. The challenges are fewer in those areas because there is a large diversity of people there.
In the areas, for example, of computer engineering, electrical engineering—my personal background, though not any more, is transportation engineering—it's still largely men in those industries. The industries vary, so you'll have a lot of women in government, because in government there are systems in place and protection in place and equity is far more.... What's the word I'm looking for? You can see it; it's right there. It gets reported on. It doesn't necessarily in private industry, so it's difficult to try to quantify what the challenges may be.
Anecdotally, we've heard about a number of challenges. They largely relate to work-life balance, and we're hearing those same challenges now from the new generation of people working, where the men are just as interested in work-life balance as are the women. The biggest challenge for us, really, is in management styles. We need to get more women into the senior levels. The management styles that women have are quite different from the management styles that men have. Women tend to be collaborative; men tend to be hierarchical. I'm painting with a broad brush.
