Appendix A: Mandatory procedure for the Enterprise Architecture Framework

Enterprise Architecture definition

Enterprise Architecture (EA) is a conceptual blueprint that defines the structure and operation of an organization considering and aligning business, information, application, technology, and security domains to support strategic outcomes.  

The Enterprise Architecture Framework:

1. Prescribes expectations of the Chief Information Officer (CIO) of Canada regarding enterprise architecture.

2. Contributes to the Chief Information Officer (CIO) of Canada responsibility for establishing and chairing an enterprise architecture review board that is mandated to defines the current and target architecture standards for the Government of Canada.

3. Provides the criteria used by Government of Canada enterprise architecture review board and departmental architecture review boards when reviewing digital initiatives to ensure their alignment with enterprise architectures.

These procedures take effect on December 1, 2020. (proposed)

These procedures are an update and replacement of Appendix A. Mandatory Procedures for Enterprise Architecture Assessment.

Refences to the Policy on Service and Digital and to the Directive on Service and Digital

A.2.1 These procedures provide details on the requirements set out in sections:

4.1.2.3 of the Policy on Service and Digital (The Chief Information Officer (CIO) of Canada is responsible for: Prescribing expectations with regard to enterprise architecture.)

4.1.2.4 of the Policy on Service and Digital (The Chief Information Officer (CIO) of Canada is responsible for: Establishing and chairing an enterprise architecture review board that is mandated to define current and target architecture standards for the Government of Canada and review departmental proposals for alignment.)

4.1.1.1 of the Directive on Service and Digital. (The departmental Chief Information Officer (CIO) is responsible for: Chairing a departmental architecture review board that is mandated to review and approve the architecture of all departmental digital initiatives and ensure their alignment with enterprise architectures.

A.2.2 The Enterprise Architecture Framework prescribes the expectations of The Chief Information Officer (CIO) of Canada with regard to enterprise architecture,  defines the current and target architecture standards for the Government of Canada and is the criteria used by the Government of Canada enterprise architecture review board and departmental architecture review boards when reviewing digital initiatives to ensure their alignment with enterprise architectures across business, information, application, technology, security domains to support strategic outcomes.

Status

The EA Framework was presented at GC EARB on July 16th, 2020. Additional feedback has been sought from the departments by August 31st, 2020, before it will return to GC EARB for an endorsement in the fall of 2020.

Business Architecture

Business architecture is a critical aspect for the successful implementation of the GC Enterprise Ecosystem Target Architecture.  The architectural strategy advocates whole-of-government approach where IT is aligned to business services and solutions are based on re-useable components implementing business capabilities in order to deliver a cohesive user experience.   As such, it is essential that business services, stakeholder needs, opportunities to improve cohesion and opportunities for re-use across government be clearly understood.   In the past these elements have not been a priority.  It is expected that the IT culture and practices will have to change to make business architecture, in general, and these elements a primary focus.

Fulfill Design services digitally from end-to-end to meet the Government of Canada users and other stakeholder's needs

  • Clearly identify internal and external users and other stakeholders and their needs for each policy, program and business service
  • Include policy requirement applying to specific users and other stakeholder groups, such as accessibilities, gender based+ analysis, and official languages in the creation of the service
  • Model end-to-end business service delivery to provide quality, maximize effectiveness and optimize efficiencies across all channels (e.g lean process)

Architect to be Outcome Driven and Strategically Aligned to the Department and to the Government of Canada

  • Identify which departmental/GC business services, outcomes and strategies will be addressed
  • Establish metrics for identified business outcomes throughout the lifecycle of an investment
  • Translate business outcomes and strategy into business capability implications in the GC Business Capability Model to establish a common vocabulary between business, development, and operation

Promote Horizontal Enablement of the Enterprise

  • Identify opportunities to enable business services horizontally across the GC enterprise and to provide cohesive experience to users and other stakeholders
  • Reuse common business capabilities, processes and enterprise solutions from across government and private sector
  • Publish in the open all reusable common business capabilities, processes and enterprise solutions for others to develop and leverage cohesive horizontal enterprise services

Information Architecture

Information architecture best practices and principles remain consistent, but their focus must accommodate the needs of a business service and business capability orientation.  In order to share information across Government, information architecture must address the higher standards needed in terms of the awareness of the information handling needs of each piece of data – its source, quality, and associated policy obligations. Collection, use and management of personal information requires adherence to the principles and requirements of GC privacy legislation and its related policies.

Collect data to address the needs of the users and other stakeholders where permissible by law

  • Assess data requirements based on users and other stakeholder needs
  • Collect only the minimum set of data needed to support a policy, program, or service
  • Reuse existing data assets and only acquire new data if required
  • Ensure data collected, including from third party sources, are of high quality

Manage and re-use data strategically and responsibly

  • Define and establish clear roles, responsibilities, and accountabilities for data management
  • Identify and document the lineage of data assets
  • Define retention and disposition schedules in accordance with business value as well as applicable privacy and security policy and legislation
  • Ensure data are managed to enable interoperability, reuse and sharing to the greatest extent possible within and across departments in government to avoid duplication and maximize utility, while respecting security and privacy requirements
  • Contribute to and align with enterprise and international data taxonomy and classification structures to manage, store, search and retrieve data

Use and share data openly in an ethical, privacy-centric and secure manner

  • Share data openly (for example on Canada’s Open Data portal) by default as per the Directive on Open Government and Digital Standards, while adhering to existing enterprise and international standards, including on data quality and ethics
  • Ensure data formatting aligns to existing enterprise and international standards on interoperability. Where none exist, develop data standards in the open with key subject matter experts, in consultation with the Enterprise Data Community of Practice
  • Ensure that combined data does not risk identification or re-identification of  personal information – de-identification techniques should be considered prior to sharing personal information

Design with privacy in mind for the collection, use and management of personal Information

  • Consult the departmental ATIP Office, reference the Privacy Act and Access to Information Act for guidance and application of the policies.
  • Determine if the initiative will be collecting, using, disclosing, retaining sharing and disposing personal information, which is any recorded information about an identifiable individual
  • Only collect personal information if it directly relates to the operation of the programs or activities
  • Notify individuals of the purpose for collection at the point of collection by including a privacy notice
  • Design processes so personal information remains accurate, up-to-date and as complete as possible, and the ability to correct
  • Personal information should be collected directly from individuals but can be from shared sources where permitted by the Privacy Act
  • Personal information needs to be available to facilitate Canadians’ right of access to and correction of government records
  • Conduct a Privacy Impact Assessment (PIA) to identify and mitigate privacy risks for new or substantially modified programs when personal information is identified
  • Perform Algorithmic Impact Assessment (AIA) to support risk mitigation activities when deploying an automated decision system as per Directive on Automated Decision Making
  • Design access controls into all processes and across all architectural layers from the earliest stages of design to limit use to “need to know”  and disclosure of, and access to personal information
  • Establish procedures to address privacy breaches so they can be reported to the ATIP Office and measures to contain, and manage the breach efficiently and effectively

Application Architecture

Application architecture practices must evolve significantly for the successful implementation of the GC Enterprise Ecosystem Target Architecture. Transitioning from legacy systems based on monolithic architectures to architectures that oriented around business services and based on re-useable components implementing business capabilities, is a major shift.   Interoperability becomes a key element, and the number of stakeholders that must be considered increases.

Use Open Source Solutions hosted in Public Cloud

  • Select existing solutions that can be reused over custom built
  • Contribute all improvements back to the communities
  • Register Open Source software to the Open Resource Exchange

Use Software as a Service (SaaS) hosted in Public Cloud

  • Choose SaaS that best fit for purpose based on alignment with SaaS capabilities
  • Choose a SaaS solution that is extendable
  • Configure SaaS and if customization is necessary extend as Open Source modules

Design for Interoperability

  • Design systems as highly modular and loosely coupled services
  • Expose services, including existing ones, through APIs
  • Make the APIs discoverable to the appropriate stakeholders

Technology Architecture

Technology architecture is an important enabler of highly available and adaptable solutions that must be aligned with the chosen application architecture. Cloud adoption provides many potential advantages by mitigating the logistical constraints that often negatively impacted legacy solutions hosted “on premises”.  However, the application architecture must be able to enable these advantages.

Use Cloud first

  • Adopt the use of the GC Accelerators to ensure proper Security and Access Controls
  • Enforce this order of preference: Software as a Service (SaaS) first, then Platform as a Service (PaaS), and lastly Infrastructure as a Service (IaaS)
  • Fulfill Cloud Services through SSC Cloud Brokering Services
  • Enforce this order of preference: Public cloud first, then Hybrid cloud, then Private cloud, and lastly non-cloud (on-premises) solutions
  • Design for cloud mobility and develop an exit strategy to avoid vendor lock-in

Design for Performance, Availability, and Scalability

  • Ensure response times meet user needs, and critical services are highly available
  • Support zero-downtime deployments for planned and unplanned maintenance
  • Use distributed architectures, assume failure will happen, handle errors gracefully, and monitor performance and behaviour actively
  • Establish architectures that supports new technology insertion with minimal disruption to existing programs and services
  • Control Technical Diversity - design systems based on modern technologies and platforms already in use.

Follow DevSecOps Principles

  • Use continuous integration and continuous deployments (CI/CD)
  • Ensure automated testing occurs for security and functionality
  • Include your users and other stakeholders as part of DevSecOps process

Security Architecture and Privacy

The GC Enterprise Security Architecture (ESA) program is a government-wide initiative to provide a standardized approach to developing IT security architecture, ensuring that basic security blocks are implemented across the enterprise as the infrastructure is being renewed.

Security architecture and privacy has always been an important but often poorly addressed aspect of solution design.  However, for the successful implementation of the GC Enterprise Ecosystem Target Architecture depends on a proper security architectural implementation.  Legacy systems based on monolithic architectures often had simplistic approaches to mitigating security risks. The future digitally enabled GC services will support a diverse community and have interoperating components spread across multiple environments.  It is critical that security be built into all processes and across all architectural layers.

Build Security into the System Life Cycle, Across All Architectural Layers

  • Identify and categorize information based on the degree of injury that could be expected to result from a compromise of its confidentiality, integrity and availability.
  • Implement a continuous security approach, in alignment with CCCS’s IT Security Risk Management Framework. Perform threat modelling to minimize the attack surface by limiting services exposed and information exchanged to the minimum necessary.
  • Apply proportionate security measures that address business and user needs while adequately protecting data at rest and data in transit.
  • Design systems to be resilient and available in order to support service continuity.

Ensure Secure Access to Systems and Services

  • Identify and authenticate individuals, processes and/or devices to an appropriate level of assurance, based on clearly defined roles, before granting access to information and services. Leverage enterprise services such as Government of Canada trusted digital identity solutions that are supported by the Pan-Canadian Trust Framework.
  • Constrain service interfaces to authorized entities (users and devices), with clearly defined roles. Segment and separate information based on sensitivity of information, in alignment with ITSG-22 and ITSG-38. Management interfaces may require increased levels of protection.
  • Implement HTTPS for secure web connections and DMARC for enhanced email security.
  • Establish secure interconnections between systems through secure APIs or leveraging centrally managed Hybrid IT connectivity services.

Maintain Secure Operations

  • Establish processes to maintain visibility of assets and ensure the prompt application of security-related patches and updates in order to reduce exposure to vulnerabilities, in accordance with GC Patch Management Guidance.
  • Enable event logging, in accordance with GC Event Logging Guidance, and perform monitoring of systems and services in order to detect, prevent, and respond to attacks.
  • Establish an incident management plan in alignment with the GC Cyber Security Event Management Plan (GC CSEMP) and report incidents to the Canadian Centre for Cyber Security (CCCS).

Privacy by Design

  • Perform Privacy Impact Assessment (PIA) to support risk mitigation activities when personal information is involved
  • Perform Algorithmic Impact Assessment (AIA) to support risk mitigation activities when deploying an automated decision system as per Directive on Automated Decision Making. For more info, please go to this link
  • Implement security measures to assure the protection of personal information and data
  • Take into consideration the 7 Foundational Privacy Design Principles (English only) when designing services

EA Framework Playbook

Here is an archived version of the playbook that was developed for the original EA assessment Criteria. It will updated to align the updated EA Framework once it is approved at GC EARB.

*The Open Group Architecture Framework (TOGAF) is a framework for enterprise architecture that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. TOGAF has been adopted by the Government of Canada.
