Staffing Ratios for Data Warehouse and BI Functions

November, 2009


Data warehouses are growing in size, scope, and complexity as they serve increasing numbers of demanding users. For businesses today, properly scaling data warehouse and business intelligence (BI) applications while controlling support costs looms as a key challenge. This study, based on a survey of more than 200 IT organizations, provides benchmarks for staffing the data warehouse, data architect, data analyst, and BI functions. We provide the ratio of data warehouse/BI staff to total IT staff for the composite sample and by organization size. We also provide median staffing ratios by business sector and discuss how to ensure these functions are adequately supported. (11 pp., 6 figs.)
