As demand for online network services continues to grow, service providers are looking to meet this need and avail themselves of business opportunities. However, despite strong growth in demand,providers continue to have dif .culty achieving profitability, customer churn remains high,and network performance continues to draw complaints. We suggest that strategicbusiness planning for network services would benefit from a systems thinking approach that analyzes the feedback effects present in the underlying business process. These feedback loops can be complex and have significant impact n business performance. For instance, while the size of a providers customer base depends on price and network performance, network performance is itself dependent on the size of the customer base. In this paper, we develop a planning model that represents these feedback effects using the finite difference equations methodology of systems dynamics.The model is validated by showing its fit with essential characteristics of the underlying problem domain,and by showing its ability to rep- licate observed reference mode behaviors.Simulations are then carried out under a variety of scenarios to examine issues important to service providers.Among other findings,the simulations suggest that (a) under flat-rate pricing, lowering price to increase customer base can hurt profitability as well as network performance; (b) under usage-based pricing, lowering price need not necessarily lead to a larger customer base; and (c) in addition to price, the customers of threshold of tolerance for performance degradation plays a significant role in balancing market share with profitability. We briefly present a prototype decision support system based on the systems thinking approach, and suggest ways in which it could be used to help business planning for network services.
