One year ago it costs us about $5,000 per year per developer for the software operating system, development environment, tools, MSDN subscriptions, etc. etc. We then changed our viewpoint and focused on leveraging cloud computing and the open source community.
Our costs today per developer for software are $0. Zero dollars for a developer software environment per year.
Combine this with the elimination of server hardware and software, IT infrastructure support and maintenance, moving from a large office environment to a virtual work place with a drop in as-you-need-it office, and leveraging free video conferencing and the savings are off the chart.
The creation of intellectual capital is becoming cheaper and cheaper.
