Abstract:
ArchOptions is a real-options based model that we have pro-posed
to value the flexibility of software architectures in response to
future changes in requirements. In this paper, we build on ArchOptions
to devise an options-based model, which values the architectural
flexibility that results from a refactoring exercise. This value
assists in understanding the payoff of investing in refactoring: if
the refactored system results in an architecture that is more
flexible, such that the expected added value (in the form of options)
due to the en-hanced flexibility outweighs the cost of investing in
this exer-cise, then refactoring is said to payoff. We apply our model
to a refactoring case study from the literature.
