More and more enterprises plan to switch their legacy system to service-oriented architecture (SOA). SOA, the focus of recent software-engineering, modulizes the IT components as “services” which could be re-jointed with each other flexibly and reused to avoid building parts repeatedly. This methodology also yields network externalities (Katz and Shapiro 1986; Markus 1987) as a number of services are integrated. An enterprise could increase the number of services to earn network externalities but such benefits come with risks. / This study aims to evaluate the investment of SOA and justifies the switch of current systems to SOA. Since SOA investment is usually a long-term and risky project for most enterprises, uncertainty becomes an important evaluation factor of an SOA project. This research applies the real option approach to evaluate an SOA switching project which majorly justifies the uncertainties, and use Monte-Carlo simulation to do the option pricing work. We consider three components of uncertainty in the model– risk, exercise time and number of connecting services for reusing- and evaluate how the uncertainty relates to the value of an SOA project. Finally, this research deduces the investment strategies under uncertainties, and describes what advantages for real option SOA has which are SOA could reduce the investment friction.
