"Good" technology governance is business technology (BT) governance — a conscious effort by senior executives to establish strategies, structures, processes, and measurements for the management of technology to boost business results. In the past, technology governance focused on the IT department, which played the role of the organization's main technology supplier. But this traditional role model is changing as organizations increasingly use new technologies — such as mobile, social, cloud, analytics, and business process management (BPM) — that are often managed by stakeholders outside IT's direct control. Given this reality, senior executives need to revisit the traditional approach to technology governance, understand the directions of change, and identify the most appropriate practices for making BT governance more sustainable.
