Abstract:
Architectural stability refers to the extent an architecture is
flexible to endure evolutionary changes in stakeholders' requirements
and the environment. We assume that the primary goal of software
architecture is to guide the system's evolution. We contribute to a
novel model that exploits options theory to predict architectural
stability. The model is predictive: it provides "insights" on the
evolution of the software system based on valuing the extent an
architecture can endure a set of likely evolutionary changes. The
model builds on Black and Scholes financial options theory (Noble
Prize wining) to value such extent. We show how we have derived the
model: the analogy and assumptions made to reach the model, its
formulation, and possible interpretations. We refer to this model as
ArchOptions.
