ASOA Valence

ASOA Valence refers to the degree to which an element of an Architecture of Service-Oriented Applications (ASOA) contributes positively or negatively to the overall business value derived from the architecture. It's a measure of the 'goodness' or 'worthiness' of a service or component within the ASOA ecosystem, evaluated based on factors such as its alignment with business goals, its impact on key performance indicators (KPIs), and its contribution to desired business outcomes.

A service with high valence is considered highly valuable and supportive of the business objectives. It typically demonstrates strong alignment with business processes, efficient resource utilization, and positive contributions to measurable business outcomes like increased revenue, reduced costs, or improved customer satisfaction.

Conversely, a service with low valence may hinder the achievement of business goals. This could stem from various factors, including poor design, inadequate functionality, misalignment with business needs, performance bottlenecks, or excessive operational costs. Services with low valence may require refactoring, replacement, or decommissioning to improve the overall effectiveness of the ASOA.

The concept of ASOA Valence is used to inform decision-making related to service design, development, deployment, and maintenance. It provides a framework for prioritizing efforts and allocating resources to services that deliver the most business value, while identifying and addressing areas where improvements are needed. Understanding the valence of individual services and components helps ensure that the ASOA as a whole effectively supports and drives business success. Analyzing ASOA Valence often involves evaluating various aspects such as the service's contribution to specific business capabilities, its impact on data quality, its contribution to organizational agility, and its adherence to architectural principles.
