One of my largest datasets was employment records at a 32,000-employee firm over 10 years. Not only was the data segmented by business unit, but also by department, type of salary, and a myriad of demographic data per employee over time. I was pleased that the leader seeking information only asked to identify if any trends existed. He gave no other direction or constraint. That gave me the flexibility to analyze this huge dataset along all dimensions and variables. My research led me to establish a list of possible biases and to segment the data across multiple dimensions. The rest was the discipline of data analysis and the creation of story boards to illustrate trends and correlations.
