Helping Hand Questions for OGBA-101

Value networks are primarily concerned with identifying the participants involved in creating and delivering value. They focus on the interactions between different stakeholders, including customers, suppliers, partners, and internal departments. This approach helps in understanding how value is exchanged and co-created across the network, highlighting the roles and relationships that contribute to the overall value delivery.

The Architecture Requirements Repository within the TOGAF Architecture Repository holds the architecture requirements that have been agreed with the Architecture Board. Here’s a detailed explanation:

Architecture Requirements Repository:

This repository is a part of the larger Architecture Repository in TOGAF, which is used to store and manage all the artifacts related to the architecture.

Content of the Repository:

Agreed Requirements: It includes the architecture requirements that have been formally reviewed and agreed upon by the Architecture Board. These requirements are essential for guiding the development and implementation of the architecture.

Governance and Compliance: The repository ensures that these requirements are accessible and can be used to enforce governance and compliance throughout the architecture development process.

TOGAF ADM Phases:

Phase A: Architecture Vision: Initial requirements are identified and refined.

Phase B, C, D: Requirements are further detailed and agreed upon.

Architecture Governance: Throughout these phases, the agreed requirements are stored in the repository to ensure they guide the architecture work and are adhered to.

Purpose and Benefits:

Centralized Repository: Having a centralized repository for agreed requirements ensures that all stakeholders have access to the current and approved requirements, facilitating better coordination and compliance.

Traceability: It provides traceability of requirements throughout the architecture development lifecycle, ensuring that all decisions and designs are aligned with agreed requirements.

In summary, the Architecture Requirements Repository holds the architecture requirements that have been agreed with the Architecture Board, providing a centralized and authoritative source for guiding architecture development and ensuring compliance.
