Does the maturity of an organization’s information systems (IS) unit have a measurable impact on the organization’s financial performance and is that increased maturity acknowledged by the stock market? Drawing on existing IS maturity literature and organizational performance research, this paper proposes to analyze archival data to assess the impact of IT maturity achievement on key financial metrics. In addition, this paper will determine if the announcement of maturity achievement is rewarded with a “wealth impact” by the stock market.
