- Now that the architecture has a vision, and it's been architected and planned, it's time to get it up and running in phase G, the implementation phase. Implementation governance is exercised while the target architecture is being implemented by the organization. The task of the architect is then to check the implementation plan is being followed, and, if necessary, deal with any change requests that arise. What happens in this phase depends on the granularity of architecture. If it is strategic or segmented in nature, then the development of this will be handed over to other architects in the organization. But if the granularity is capability related, then in this phase both the detail design and implementation will be completed like a system being built. The complexities of the organizations that use the TOGAF Framework means it's likely that the best approach to implementation is in stages or transitions. This makes it possible for the business to realize the value and benefits of the architecture early on. Some general approaches include, tailoring an implementation program that enables the delivery of the transition architecture, establishing a phase timetable to reflect business priorities, following the organization's approach to corporate, IT, and architecture governance, making use of any project and or program approach, and defining an operations framework to ensure a long life for the proposed system. An important link exists between the organization of the architecture and implementation, one which will benefit from the development of architecture contracts. The contract will include the name, description, and objectives of the project, the scope, deliverables, and constraints of the project, the measures of effectiveness, or the architecture, the acceptance criteria to define what good looks like and when the architecture is complete, and the risks and issues to identify what might go wrong, and what the acceptable level of risk is. It's important to ensure that compliance with the architecture occurs, and that the implementation is compliant with projects and other ongoing projects. And that's it for the implementation phase. Next, we'll look at the last phase of the ADM, phase H, change management.
