How can our company use technology to manage/improve our corporate culture?

You don't say what type of corporate culture you are aiming for? Is this a young company needing focus and direction, or a growing company looking to stay on track (or even change course)?

I think sharing information is the best way to improve corporate culture and get everyone on the same page. Use your technology to share key metrics and how they are/not aligning with the company goals. People will react to information more consistently than a lecture. Let each area be responsible for updating and even presenting the information. The team leaders will automatically rise to the top and become proactive when they know how they impact overall company performance.

Focus on using technology to improve communication and collaboration. Promote interactive communications. Particularly if you have multiple locations or remote workers, having easy access to chat or online meetings can be helpful. Develop shared online resources (team rooms, shared directories) where individuals across departments can work collaboratively. Equip conference rooms with video conference capabilities and projectors. The more accessible these tools are, the more they will be used to promote a collaborative culture.
