Persistence and Change at the Top of the IT Sector

We use the DATAMATION index of the top 50 domestic IT companies (1975–1995) to track persistence and change at the top of the sector. The trends that we uncover are increasing instability, rejuvenation (declining average age of entrants coupled with increasing average age of quitters), democratization (diminishing revenue inequality at the top) and growing supply‐side intertwining of sub‐sectors and industries within IT due to diversification by long‐term survivors.

Optimized Software Licensing – Combining License Types in a License Portfolio

Although software licenses usually range among the most expensive items within the IT budget, they still lack the necessary attention by many companies. Therefore, most companies inadequately have implemented their software asset management neglecting further potential for cost reduction, which can be obtained by optimizing the use of different license types. This paper shows how possible savings can be realized by combining different types of licenses in a license portfolio. The model presented is based on the most common license types considering different user groups as well as their behavior. Additionally to cost risks, the risk of service quality is also taken into consideration. The following examples illustrate the model’s high relevance and show how it can be applied in practice. Accepted after two revisions by Prof. Dr. Hasenkamp.
