Sub-fields within I.S. generate benefits for their participants and for the larger research discipline. Sub-fields can also fragment and compete with the broad field they emerge from. One of the largest and most active research groups in the ICIS community is the researchers examining Information Systems Economics. After 20 years of the Workshop on Information Systems and Economics (WISE), this is a moment to identify what sub-fields contribute in I.S. and look forward to what sub-fields can do for ICIS researchers and I.S. practice in the future.
