The www.webventurer.co.uk site aims to show how sound businesses can be built on the back of the company's .net technologies.
Microsoft's partners in the initiative include PriceWaterhouseCoopers, KPMG, Internet hosting firm Attenda, and Internet consultancies www.netcraft.com and www.blueberry.com.
The site offers guidance on building start-up businesses that can attract venture capital funding. The company claims this information will also be of use to established companies when evaluating their own business plans.
"I have come across one company that is applying the rigours of a venture capital exercise to its own e-business plans," said Allan Dorman, systems engineer manager at Microsoft.
Speaking from his own experience, Eiren O'Keefe, chief technology officer at Blueberry, said, "Moving to e-business is similar to the move to ERP. If it doesn't work on paper, there's no hope of getting it right when implementing the technology."
Keefe said that businesses were no longer trying to throw a Web site together in a matter of months. "Now businesses are slowing down and planning more effectively," he explained.
