TOGAF Knowledges Assortment – CyberSecurity Memo

 makes adoption of greatest practices simpler. It’s going to present you the place to seek out enduring and common ideas and confirmed greatest follow and it’ll additionally underscore the place to search for new rising concepts. Collectively common ideas, greatest follow steerage, and rising concepts are the way you adapt the TOGAF Normal on your configured Enterprise Structure follow. 

Let’s begin by reviewing enterprise structure frameworks; there are too many to call right here, so we are going to follow probably the most well-known. Quite a few structure frameworks exist at this time, akin to TOGAF, Zachman Framework, NIST, SOA. A short abstract of every framework is printed beneath (this isn’t a complete definition, only a transient define for consciousness and context).

Totally different deisgn shall be used for various function of every stage of challenge, additionally shall be trageted for various sort of audiences.

A Methods Architect obligations consists of the flexibility to create, overview, and replace (don’t overlook this final one!) designs or blueprints to offer an general path for the system, challenge, division, or enterprise.

Contextual Design  The place you wish to go: mission/imaginative and prescient)

This the area or the context wherein your downside exists or manifests and also you wish to clear up it. Principally it’s the 20,000 foot stage.

Usually it shall be going from
Contextual —-> Conceptual —–> Logical ——> Bodily.

Conceptual Design  (flesh out the context into ideas ) 

A conceptual design is an summary or excessive stage design which incorporates solely the most necessary elements and entities. The primary aim of a conceptual design is to offer an comprehensible image of the general function of the proposed answer. Elements could embrace main expertise programs, exterior programs which are required for integration or general performance, excessive stage information circulate, and system performance. Consider this because the “black field” diagram the place parts of the diagram could also be merely a expertise element to-be-named-later however is recognized with its function and function.

Logical Design  ( Group them below a bucket/performance and so forth)

A logical design is a extra detailed design which incorporates all main elements and entities plus their relationships


. The info flows and connections are detailed on this stage. The audience is usually builders or different programs architects. Nevertheless, it’s potential to create logical designs for enterprise functions to make sure that all elements and performance is accounted and properly understood. Logical designs don’t embrace bodily server names or addresses. They do embrace any enterprise companies, software names and particulars, and different related info for growth functions.

Bodily Design  ( Depart it to Implementation)

A bodily design has all main elements and entities recognized inside particular bodily servers and areas or particular software program companies, objects, or options. Embrace all identified particulars akin to working programs, model numbers, and even patches which are related. Any bodily constraints or limitations must also be recognized inside the server elements, information flows, or connections. This design often precludes or could also be included and prolonged by the ultimate implementation workforce into an implementation design.


The UML (Unified Modeling Language) can be one other methodology that may be explored for design and definition for these and different designs. There are a number of diagram varieties inside the UML which may very well be developed at every one in every of these design levels. I’d have an interest to listen to about your curiosity or experiences with growth of those designs or others much like it. Additionally, some consider there ought to be varied focus areas such because the Microsoft Structure  format with enterprise, software, expertise, and data views of every of those levels. It will depend upon the maturity of your organization’s structure program and in addition the challenge scope and audience on your designs.

  • Lucid Charts — my go-to answer
  • Orbus Software program — helps Conceptual, Logical, Bodily diagrams (
  • C4 mannequin — for visualizing software program structure (modeling not diagraming, one other strategy) —
  • ArchiMate — mannequin pushed
  • MEGA — BPMN modeling

Structure vs Design 

Structure focuses on what and design focuses on how; the important thing distinction between structure and design is general scope and stage of element (and thus meant utilization)


Construction of the TOGAF Doc

There are 4 most important components to the TOGAF doc:

(Introduction) This Half offers a high-level introduction to a few of the key ideas behind enterprise structure and specifically the TOGAF strategy.
(Structure Improvement Technique) That is the core of TOGAF. It describes the TOGAF Structure Improvement Technique (ADM) – a step-by-step strategy to growing an enterprise structure.
(Enterprise Continuum) This Half describes the TOGAF Enterprise Continuum, a digital repository of structure belongings, which incorporates the TOGAF Basis Structure, and the Built-in Info Infrastructure Reference Mannequin (III-RM).
(Sources) This Half contains the TOGAF Useful resource Base – a set of instruments and methods out there to be used in making use of TOGAF and the TOGAF ADM.

4 Commom Architectuer Utilizing TOGAF

There are 4 forms of structure which are generally accepted as subsets of an general enterprise structure, all of which TOGAF is designed to help:

  • A Enterprise (or Enterprise Course of) Structure – this defines the enterprise technique, governance, group, and key enterprise processes.
  • A Knowledge Structure – this describes the construction of a corporation’s logical and bodily information belongings and information administration sources.
  • An Functions Structure – this type of structure offers a blueprint for the person software programs to be deployed, their interactions, and their relationships to the core enterprise processes of the group.
  • A Know-how Structure – this describes the logical software program and {hardware} capabilities which are required to help the deployment of enterprise, information, and software companies. This consists of IT infrastructure, middleware, networks, communications, processing, requirements, and so forth.

TOGAF Primary Elements

TOGAF offers a commonsense, sensible, prudent, and efficient methodology of growing an enterprise structure.

TOGAF consists of three most important components:

  1. The TOGAF Structure Improvement Technique (ADM), which explains learn how to derive an organization-specific enterprise structure that addresses enterprise necessities. The ADM offers:
    • A dependable, confirmed manner of growing the structure
    • Structure views which allow the architect to make sure that a fancy set of necessities are adequately addressed
    • Linkages to sensible case research
    • Tips on instruments for structure growth
  2. The Enterprise Continuum, which is a “digital repository” of all of the structure belongings – fashions, patterns, structure descriptions, and so forth. – that exist each inside the enterprise and within the IT business at giant, which the enterprise considers itself to have out there for the event of architectures. At related locations all through the TOGAF ADM, there are reminders to contemplate which structure belongings from the Enterprise Continuum the architect ought to use, if any. TOGAF itself offers two reference fashions for consideration for inclusion in an enterprise’s personal Enterprise Continuum:
    1. The TOGAF Basis Structure – an structure of generic companies and features that gives a basis on which particular architectures and Structure Constructing Blocks (ABBs) might be constructed. This Basis Structure in flip consists of:
      • The TOGAF Technical Reference Mannequin (TRM), which offers a mannequin and taxonomy of generic platform companies
      • The TOGAF Requirements Info Base (SIB), which is a database of open business requirements that can be utilized to outline the actual companies and different elements of an enterprise-specific structure
    2. The Built-in Info Infrastructure Reference Mannequin (III-RM), which relies on the TOGAF Basis Structure, and is particularly aimed toward serving to the design of architectures that allow and help the imaginative and prescient of Boundaryless Info Stream.
  3. The TOGAF Useful resource Base, which is a set of sources – pointers, templates, background info, and so forth. – to assist the architect in the usage of the ADM.


 Structure Improvement Technique

The TOGAF Structure Improvement Technique (ADM) offers a examined and repeatable course of for growing architectures. The ADM consists of establishing an structure framework, growing structure content material, transitioning, and governing the belief of architectures.

All of those actions are carried out inside an iterative cycle of steady structure definition and realization that enables organizations to remodel their enterprises in a managed method in response to enterprise objectives and alternatives.

Phases inside the ADM are as follows:

  • The Preliminary Section describes the preparation and initiation actions required to create an Structure Functionality together with customization of the TOGAF framework and definition of Structure Ideas
  • Section A: Structure Imaginative and prescient describes the preliminary part of an structure growth cycle

    It consists of details about defining the scope of the structure growth initiative, figuring out the stakeholders, creating the Structure Imaginative and prescient, and acquiring approval to proceed with the structure growth.

  • Section B: Enterprise Structure describes the event of a Enterprise Structure to help the agreed Structure Imaginative and prescient
  • Section C: Info Methods Architectures describes the event of Info Methods Architectures to help the agreed Structure Imaginative and prescient
  • Section D: Know-how Structure describes the event of the Know-how Structure to help the agreed Structure Imaginative and prescient
  • Section E: Alternatives & Options conducts preliminary implementation planning and the identification of supply automobiles for the structure outlined within the earlier phases
  • Section F: Migration Planning addresses learn how to transfer from the Baseline to the Goal Architectures by finalizing an in depth Implementation and Migration Plan
  • Section G: Implementation Governance offers an architectural oversight of the implementation
  • Section H: Structure Change Administration establishes procedures for managing change to the brand new structure
  • Necessities Administration examines the method of managing structure necessities all through the ADM
