Value Streams
Value streams are one of the core elements of a Business Architecture. This document provides an architected approach to developing a business value model. It addresses how to identify, define, model, and map a value stream to other key components of an enterprise’s Business Architecture.
TOGAF® Series Guide:
Information Mapping

TOGAF® Series Guide:
Organization Mapping
This document shows how organization mapping provides the organizational context to an Enterprise Architecture. While capability mapping exposes what a business does and value stream mapping exposes how it delivers value to specific stakeholders, the organization map identifies the business units or third parties that possess or use those capabilities, and which participate in the value streams.
TOGAF® Series Guide:
Business Scenarios
This document describes the Business Scenarios technique, which provides a mechanism to fully understand the requirements of information technology and align it with business needs.
