Speaking here on the first day of the Linux specialist's annual user conference,
"There is still a lot we need to do around execution. One thing I have heard from customers and partners over the last few months is that we are basically kind of tough to do business with--great technology but not necessarily the easiest company to do business with," he said Wednesday.
"Quite frankly we found out in the first six months that our customers don't want to consume software via an exchange so we have morphed that into a fully fledged open-source ISV program," he said, using the acronym for independent software vendor.
As well as improving how the company interacts with customers, Whitehurst said that that his new employer's future lies in becoming an open-source adviser to end-user companies to allow them to share internally developed software with the rest of industry.
Red Hat has done very well so far with a business model of making community-developed software enterprise-ready, but there is still a whole lot more that could be achieved, said Whitehurst.
"One thing is clear: we have built a great business around open source, but I would argue that that is a specific sliver of open source," he said. "In my view...that is the tip of the iceberg; the vast majority of software is written in the enterprise and not for resale. And the vast majority of that is never used; the waste in software development is extraordinary."
Whitehurst claimed Red Hat's future lies in helping and encouraging companies to share internally developed software with other businesses, thereby increasing the number of open-source applications and platforms available.
"For open source to provide the value to all our customers worldwide, we need to get our customers as not only users of open-source products but truly engaged in open source as part of the development community," he said.
