Figure: Phase G: Implementation
Governance
Objectives
The objectives of Phase G are to:
- Formulate recommendations for each implementation project.
- Construct an Architecture Contract to govern the overall implementation and deployment process.
- Perform appropriate governance functions while the system is being implemented and deployed.
- Ensure conformance with the defined architecture by implementation projects and other projects.
Approach
It is here that all the information for successful management of the various implementation projects is brought together. Note
that in parallel with Phase G there is the execution of an organizational-specific development process, where the actual
development happens.
Phase G establishes the connection between architecture and implementation organization, through the Architecture Contract.
Project details are developed, including:
- Name, description, and objectives
- Scope, deliverables, and constraints
- Measures of effectiveness
- Acceptance criteria
- Risks and issues
Implementation governance is closely allied to overall architecture governance, which is discussed in Part IV: Resource Base , Architecture Governance .
A key aspect of Phase G is ensuring compliance with the defined architecture(s), not only by the implementation projects, but
also by other ongoing projects within the enterprise. The considerations involved with this are explained in detail in Part IV: Resource Base , Architecture Compliance .
Inputs
Inputs to Phase G are:
Steps
Key steps in Phase G include:
- Formulate Project
recommendation formulation - for
Recommendation
For each separate implementation project do the following:
- Document scope of individual project in Impact Analysis
- Document strategic requirements (from the architectural perspective) in Impact Analysis
- Document change requests (such as support for a standard interface) in Impact Analysis
- Document rules for conformance in Impact Analysis
- Document timeline requirements from roadmap in Impact Analysis
- Document Architecture
Contract: Contract
- Obtain signature from all developing organizations and sponsoring organization
- Review Ongoing

Outputs
The outputs of Phase G are:
- Note:
- The implemented system is actually an output of the development process. However, given the importance of this output, it is
stated here as an output of the ADM. The direct involvement of architecture staff in implementation will vary according to
organizational policy, as described in Part IV: Resource Base , Architecture Governance .
