I recently came upon an interesting article detailing many of the challenges that keep top corporate CIOs up at night. Gery Menegaz makes some great points on the many, rapidly changing pressures that CIOs face in a constantly evolving and unpredictable technology and business landscape. I'd highly recommend the article; he presents many great, solid insights from some leading CIOs on big data, cloud, BYOD, security, and the myriad other challenges that CIOs face as technology continues to rapidly transform.
