Читать книгу IT Architecture from A to Z: Theoretical basis. First Edition - Vadim Aldzhanov - Страница 17

To implement the TOGAF methodology, the question arises: what is the minimum set of documents required to maintain an architectural project? Extra documents mean extra time and funds. From my own experience and theory (during preparation for certification), the minimum set can consist of eight documents:

• The Main Methodologies are Templates, Business Principles, Goals, Drivers, required to understand the company’s mission, goals, and strategy and register the business principles. See Template “TOGAF 9 Templates, Business Principles, Goals, Drivers.doc”

• Architecture Principles are the rules to guide the work on architecture. Architectural decisions are made based on these principles. Principles need to be formulated based on TOGAF examples. Using principles when working on architecture has proven its effectiveness. See Template “TOGAF 9 Template Architecture Principles.doc”

• Architecture Vision is a high-level description of the desired end product of an architectural project. So, these are the results to achieve. Description of the solution of the problems and tasks to start the project for. This document is important for interaction with the project sponsor and other stakeholders. See Template “TOGAF 9 Template Architecture Vision.doc”

• Statement of Architecture Work is an agreement between the sponsor and the project team on the implementation of the work. It includes all the frameworks, restrictions, assumptions, terms, budget, and project rules. It designates the project manager and states his/her rights and responsibilities. Addendum includes the architecture vision as a description of the project framework. See Template “TOGAF 9 Template Statement of Architecture Work.doc”

• Architecture Definition is a presentation of the current and target architecture and covers each of the architectural domains i.e. business, data, applications, and technology, as well as an analysis of the discrepancies between the current and future state. See Template “TOGAF 9 Template Architecture Definition.doc”

• Architecture Requirements Specification is a document providing a quantitative view of the requirements, restrictions, suggestions, and measurable criteria that must be met during the implementation of the architecture. See Template “TOGAF 9 Template Architecture Requirements Specification.doc”

• Transition Architecture. The implementation of the target architecture has several stages. Each intermediate state must be workable and valuable. This document groups projects for each of these stages. See Template “TOGAF 9 Template Transition Architecture.doc”

• Implementation and Migration Plan is a consolidated implementation plan for projects aimed to achieve the target architecture. It also includes benefits, scope, timeframe, cost, risks, and milestones of projects. See Template “TOGAF 9 Template Implementation and Migration Plan.doc”

Such set of documents can be done rapidly and in a cost-effective way. If you are going to use third party services, I recommend to include one more document – an architectural contract. This is an agreement between architects and IT project executives. See Template – “TOGAF 9 Template – Architecture Contract.doc” When accepting a project, it will be easier for you to get the desired result if you have agreed on it beforehand.
