Implementing a successful metrics system in an IT company involves defining goals and key performance indicators from both a top-down and bottom-up approach. Quality metrics should track factors like cost of quality, defects, and rework trends over time. Regular collection and analysis of metrics on projects, processes, and people can provide insights into trends and areas for improvement. Both business objectives and individual project success can be better managed through an iterative process of planning, collecting, analyzing, and evolving organizational metrics.
