Different audiences want different things.
You're assuming these pages are for average customers:
Why would users even care about the people working there? I just want a working piece of software and thats good...right?
...but those aren't the only people viewing a company's website.
A well-run website design process begins with an audit of all a site's intended users and their particular user needs. Depending on the company this may include:
- Potential business partners or clients. Small in number, very high value, these will want to gauge the size, skills, areas of expertise and levels of capacity and flexibility of the company (particularly the senior specialists), plus whether they seem like people they can do business with.
- Job seekers. Either responding to an advert, pro-actively looking for a company like this one, or having encountered the company through networking or similar, they will often want to gauge if this is the sort of company where they'd fit in.
- Investors, lenders, banks etc. Similar to potential partners, these will want to gauge the capabilities and viability of the company. Possibly more interested in the upper management and their track record.
- Press. If your company does something remarkable, journalists on a deadline will appreciate being able to copy and paste some quick facts that flesh out the story of the company, or that give its claims and comments credibility.
...and so on. Consider also, conference organisers, people following up on encountering a company rep at a networking event or trade fair, bulk buyers, etc etc.
Some company sites will have such user needs, some won't.
If one does, and the site's designed well, this kind of information will be somewhere the above groups can find it easily, but which isn't in the way for average customers who only care about the product.
