I recently attended the 19th annual CIO 100 Symposium, where we honored the top CIOs in the country. Here\u2019s what I learned from them. (And for more lessons learned from the CIO 100, go to www.cio.com\/081506.)\u2022 Mobile, shmobile. Only one in 10 enterprise workers has access to e-mail on a BlackBerry or Palm Treo, and even fewer can access business apps on those devices. Conclusion: There\u2019s huge growth potential in the enterprise mobility market.\u2022 Communication, communication and more communication, among all levels of your IT staff, is critical to delivering innovative solutions. Regulatory and legal issues are the biggest external roadblocks to innovation, while unsupportive corporate cultures and inadequate funding constitute the main internal speed bumps.\u2022 Training end users\u2014initially and continually\u2014is the most important thing a CIO can do when rolling out an innovative application.\u2022 If you want to be innovative, you gotta embrace your failures and accidents.\u2022 Don\u2019t even try to stop the tsunami of consumer devices entering your infrastructure. It\u2019s a losing battle. In fact, it\u2019s already been lost. (But put Skype at the top of your public enemies list.)\u2022 Saving money ("the whole mess for less") is absolutely the worst reason to outsource. You outsource to grow your business the right way.\u2022 Vendors do not sell service-oriented architecture solutions; CIOs must buy them.\u2022 The CIO\u2019s future role will morph into the CEO\u2019s present job.\u2022 My biggest lesson? Realizing how much I didn\u2019t know!
