  • the bridge to the new town a legacy system migration pattern
    European Conference on Pattern Languages of Programs, 2000
    Co-Authors: Wolfgang Keller

    Abstract:

    Imagine you are the person responsible for the Application Portfolio of a large insurance company. For their business the company runs one monolithic system for most of its product divisions1. This system is 25 years old, written in Assembler and sits on an IMS/DB database. This is the old town. It’s at the end of it’s potential growth and people want to move out of it to the other side of the river. Let’s call this old system (or town) CLS for complete legacy system. You want to replace this system with newer systems, a new town, in a step by step

  • ICIS – NARROW FRAMING EFFECTS ON REAL OPTIONS: THE CASE OF IT Application PortfolioS
    , 2010
    Co-Authors: Sarah S. Khan, Ram L. Kumar, Moutaz J. Khouoja, Kexin Zhao

    Abstract:

    Real options theory has been advocated as a solution to IT investment problems with uncertainty around future outcomes and the inability of traditional financial measures to account for managerial flexibility. On the one hand, it is argued that real option analysis captures and formalizes managers’ intuition, thus creating a disciplined decision making process. On the other hand, the intuitive valuation of the options is criticized due to the prevalent effects of various judgmental biases. Through this study, we try to capture one of the biases that can affect the real option value at exercise time in an IT Application Portfolio setting i.e. narrow framing. We also explore the impact of uncertainty around outcomes on real option exercise time. By conducting an online experiment using experimental choice analysis with IT managers as subjects, we try to see if they are prone to simplifying complicated real option exercise decisions by isolating them.
