Architecture Contracts are essential agreements in the TOGAF Architecture Development Method (ADM) that define the responsibilities and expectations between stakeholders in an architecture project. These contracts ensure successful implementation and governance of the architecture by outlining deliverables, quality standards, and the processes for collaboration. This guide provides an in-depth understanding of Architecture Contracts, their benefits, contents, and roles within the TOGAF ADM, along with a template and a realistic example.
Purpose of Architecture Contracts
Architecture Contracts serve as joint agreements between development partners and sponsors, outlining the deliverables, quality, and fitness-for-purpose of an architecture. They ensure that all parties involved in the architecture project have a clear understanding of their responsibilities and the expected outcomes.
Key Benefits:
- Continuous Monitoring: Establishes a system for monitoring the integrity, changes, decision-making, and audit of architecture-related activities.
- Clarity and Accountability: Defines clear responsibilities and expectations, promoting accountability and transparency.
- Effective Governance: Ensures that the architecture is implemented and governed effectively, aligning with business objectives and regulatory requirements.
Contents of Architecture Contracts
Architecture Contracts typically include the following components:
- Defined Phases of Deliverables: Outlines the phases of the architecture project and the expected deliverables for each phase.
- Prioritized Joint Workplan: Details the tasks and activities required to achieve the architecture objectives, prioritized based on importance and dependencies.
- Time Windows: Specifies the timelines for each phase and deliverable, ensuring that the project stays on track.
- Architecture Delivery and Business Metrics: Defines the metrics used to measure the success and effectiveness of the architecture implementation.
Types of Architecture Contracts and ADM Stages
1. Statement of Architecture Work
Created in Phase A (Architecture Vision) of the TOGAF ADM, this contract outlines the agreement between the architecting organization and the sponsor of the Enterprise Architecture or the IT governance function. It defines the scope, objectives, and expected outcomes of the architecture work.
Example:
- Scenario: A financial institution is initiating an enterprise architecture project to improve data management and compliance.
- Implementation: The Statement of Architecture Work outlines the project’s scope, objectives, and expected deliverables, ensuring alignment with the institution’s strategic goals and regulatory requirements.
2. Contracts with Systems Integrators, Applications Providers, and/or Service Providers
These contracts govern the development of one or more architecture domains (Business, Data, Application, Technology) or the oversight of the overall Enterprise Architecture. They define the deliverables, quality, and processes for collaboration between the architecture function and external partners.
Example:
- Scenario: A retail company is partnering with a systems integrator to implement a new ERP system.
- Implementation: The contract outlines the deliverables, quality standards, and collaboration processes, ensuring that the ERP system meets the company’s business and technical requirements.
3. Contracts between the Architecture Function and the Implementation Function
Established at the beginning of Phase G (Implementation Governance), this contract outlines the agreement between the architecture function and the implementation function. It ensures that the implementation aligns with the architecture defined in the preceding ADM phases.
Example:
- Scenario: A manufacturing company is implementing a new supply chain management system based on the defined enterprise architecture.
- Implementation: The contract ensures that the implementation adheres to the architectural requirements and business objectives, promoting consistency and quality.
4. Business Stakeholder’s Architecture Contract
This contract includes project scope, deliverables, constraints, measures of effectiveness, acceptance criteria, risks, and issues. It ensures that the architecture meets the business stakeholders’ requirements and expectations.
Example:
- Scenario: A healthcare provider is implementing a new patient management system to improve patient care and operational efficiency.
- Implementation: The contract outlines the project’s scope, deliverables, and acceptance criteria, ensuring that the system meets the stakeholders’ requirements and supports the provider’s strategic goals.
Business Users’ Architecture Contract (Typical Contents)
A typical Business Users’ Architecture Contract includes the following components:
- Introduction and Background: Provides an overview of the architecture project and its objectives.
- Nature of the Agreement: Describes the purpose and scope of the agreement.
- Scope: Defines the boundaries and limitations of the architecture project.
- Strategic Requirements: Outlines the strategic objectives and goals that the architecture must support.
- Conformance Requirements: Specifies the standards, regulations, and policies that the architecture must adhere to.
- Architecture Adopters: Identifies the stakeholders who will adopt and use the architecture.
- Time Window: Specifies the timelines for the architecture project and its deliverables.
- Architecture Business Metrics: Defines the metrics used to measure the success and effectiveness of the architecture.
- Service Architecture: Includes Service-Level Agreements (SLAs) that define the expected level of service and performance.

Architecture Governance and Contracts
Architecture Contracts are essential for managing changes to the Enterprise Architecture, particularly in Phase H (Architecture Change Management) of the TOGAF ADM. They ensure that the architecture remains adaptable and aligned with evolving business needs and regulatory requirements.
Key Roles:
- Architecture Board: Responsible for the monitoring and control of Architecture Contracts, ensuring that the architecture is implemented and governed effectively.
- Architecture Governance Framework: Ensures accountability, responsibility, and discipline concerning the development and usage of all architectural artifacts.
Conclusion
Architecture Contracts play a crucial role in the TOGAF ADM, ensuring successful implementation and governance of the architecture. By defining clear responsibilities, deliverables, and expectations, these contracts promote accountability, transparency, and alignment with business objectives. This comprehensive guide, along with the template and realistic example, provides valuable insights into creating and managing Architecture Contracts, driving successful architecture projects, and achieving strategic goals.
