Enterprise Inventory (Erl)

How can services be delivered to maximize recomposition?

Problem

Delivering services independently via different project teams across an enterprise establishes a constant risk of producing inconsistent service and architecture implementations, compromising recomposition opportunities.

Solution

Services for multiple solutions can be designed for delivery within a standardized, enterprise-wide inventory architecture wherein they can be freely and repeatedly recomposed.

Application

The enterprise service inventory is ideally modeled in advance, and enterprise-wide standards are applied to services delivered by different project teams.

Impacts

Significant upfront analysis is required to define an enterprise inventory blueprint and numerous organizational impacts result from the subsequent governance requirements.

Principles

Standardized Service Contract, Service Abstraction, Service Composability

Architecture

Enterprise, Inventory

Listen to the podcasts that accompany this site

An enterprise service inventory establishes an enterprise-wide architectural boundary that promotes native interoperability and recomposition among all services.
