Evaluating Software Architectures
for Stability and Evolution with Real Options
What is ArchOptions ?
ArchOptions
combines a novel theory and a technique that use real options to
evaluate software architectures for stability and evolution.
What approach does ArchOptions take?
ArchOptions uses a synergy of real options and
viewpoints
ArchOptions & real options: the major
idea of this work is that the flexibility of an architecture to endure
changes in stakeholders requirements and the environment has a value.
This value can assist in the evaluation of an architecture for
stability. Given likely evolutionary changes, ArchOptions value the
flexibility of an architecture to expand in the face of these changes.
ArchOptions builds on Black and Scholes options theory (Nobel Prize
winning) to achieve this objective.
ArchOptions & viewpoints: the valuation using
ArchOptions necessarily requires a comprehensive solution that
incorporates multiple valuation techniques, some with subjective
estimates and others based on market data, when available. To introduce
discipline into this setting and capture the value from different
perspectives, ArchOptions adopts viewpoints as a solution.
Possible Uses
ArchOptions predictive results can have different
usages: valuing the long-term investment in a particular architecture;
analysing trade-offs between two or more candidate software
architectures for stability; analysing the strategic position of the
enterprise- if the enterprise is highly centred on the software
architecture (as it is the case in web-based service providers
companies); and validating the architecture for evolution.
