|§ clearly identify internal and external users and other stakeholders and their needs for each policy, program and business service
|
* 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 accessibility, gender-based plus analysis, and official languages in the creation of the service
* perform Algorithmic Impact Assessment (AIA) to support risk mitigation activities when deploying an automated decision system as per ''Directive on Automated Decision-Making''
* model end‑to‑end business service delivery to provide quality, maximize effectiveness and optimize efficiencies across all channels (for example, lean process)

|'''Architect to be outcome‑driven and strategically aligned to the department and to the Government of Canada'''
|'''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
|
* identify which departmental/GC business services, outcomes and strategies will be addressed
* establish metrics for identified business outcomes throughout the life cycle 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'''
|'''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
|
* 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

|'''Collect data to address the needs of the users and other stakeholders'''
|'''Collect data to address the needs of the users and other stakeholders'''
|§ assess data requirements‑based program objectives, as well users, business and stakeholder needs
|
* assess data requirements‑based program objectives, as well users, business and stakeholder needs
* collect only the minimum set of data needed to support a policy, program, or service
* reuse existing data assets where permissible and only acquire new data if required
* ensure data collected, including from third-party sources, are of high quality
|-

|'''Manage and reuse data strategically and responsibly'''
|'''Manage and reuse data strategically and responsibly'''
|§ define and establish clear roles, responsibilities, and accountabilities for data management
|
* 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 and secure manner'''
|'''Use and share data openly in an ethical and secure manner'''
|§ share data openly by default as per the ''Directive on Open Government and Digital Standards'', while respecting security and privacy requirements; data shared should adhere to existing enterprise and international standards, including on data quality and ethics
|
* share data openly by default as per the ''Directive on Open Government and Digital Standards'', while respecting security and privacy requirements; data shared should adhere 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
* ensure that combined data does not risk identification or re‑identification of sensitive or personal information
|-

|'''Design with privacy in mind for the collection, use and management of personal Information'''
|'''Design with privacy in mind for the collection, use and management of personal Information'''
|§ ensure alignment with guidance from appropriate institutional ATIP Office with respect to interpretation and application of the ''Privacy Act'' and related policy instruments
|
* ensure alignment with guidance from appropriate institutional ATIP Office with respect to interpretation and application of the ''Privacy Act'' and related policy instruments
* assess initiatives to determine if personal information will be collected, used, disclosed, retained, shared, and disposed
* 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
* personal information should be, wherever possible, collected directly from individuals but can be from other sources where permitted by the ''Privacy Act''
* personal information must be available to facilitate Canadians’ right of access to and correction of government records
* design access controls into all processes and across all architectural layers from the earliest stages of design to limit the use and disclosure of personal information
* design processes so personal information remains accurate, up‑to‑date and as complete as possible, and can be corrected if required
* de‑identification techniques should be considered prior to sharing personal information
* in collaboration with appropriate institutional ATIP Office, determine if a Privacy Impact Assessment (PIA) is required to identify and mitigate privacy risks for new or substantially modified programs that impact the privacy of individuals
* establish procedures to identify and address privacy breaches so they can be reported quickly and responded to efficiently to appropriate institutional ATIP Office

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.
