ArchiMate distinguishes three main layers: The first dimension core entities are assigned to are the different layers of an enterprise architecture model. Key relationships between diagram elements are sometimes missing or ambiguous. However you decompose your system is up to you, but I tend to identify the major logical components and their interactions. It's easy-to-use, intuitive. By visiting our website, you agree to the use of cookies as described in our Cookie Policy. The focus should be on people (actors, roles, personas, etc) and software systems rather than technologies, protocols and other low-level details. I know what "RDS" means here, but you probably don't, so that should really be fixed. it is a great way to visualise a solution and communicate it quickly plus it paves the way for collaborative design and collective code ownership. The OpenGroup ArchiMate language provides a graphical language for representing enterprise architectures over time, including strategy, transformation and migration planning, as well as the motivation and rationale for the architecture. Methods & Tools uses Google Analytics for statistics. UML provides both a common set of abstractions and a common notation to describe them, but I rarely find teams that are using either effectively. The strategy and motivation elements in the ArchiMate language can be used to support the Requirements Management, Preliminary, and Architecture Vision phases of the TOGAF ADM, which establish the high level business goals, architecture principles, and initial business requirements. Advertise | I'm not a fan of bidirectional arrows, because they tend to be harder to label correctly. You can use it as a flowchart maker, network diagram software, to create UML online, as an ER diagram tool, to design database schema, to build BPMN online, as a circuit diagram maker, and more. Sketching should be a skill in every software developer's toolbox. My approach is to use a small collection of simple diagrams that each shows a different part of the same overall story. It's high-level, clean, concise, colourful, and you might even be able to work out what's being described here. In this post I will describe our code visualization choices. He says that architecture represents the "significant decisions", where significance is measured by cost of change. Agile approaches talk about moving fast, and this requires good communication, but it is surprising that many teams struggle to effectively communicate the design of their software. Draw a simple block diagram showing your system as a box in the centre, surrounded by its users and the other systems that it interfaces with. Most of the visual models can be model by ArchiMate in TOGAF ADM as kind of visual artifacts, but not all TOGAF ADM deliverables (such as textual documentation, logs, meeting minutes) can be represented by ArchiMate. All lines are labelled too. Software Development Magazine - Project Management, Programming, Software Testing, Simple Sketches for Diagramming your Software Architecture,, Methods & Tools uses AddThis for easy content sharing. As an industry, we do have the Unified Modelling Language (UML), which is a formal standardised notation for communicating the design of software systems. Here's a better version of the diagram above. Do you understand the meaning of all icons used? Author "Software Architecture for Developers" | Creator of the "C4 model for visualising software architecture" | Founder at Structurizr | Software architecture training at, here's a link to the section in one of my talks where I discuss this, Announcing the Structurizr diagram review tool. Application layer supports the business layer with application services which are realized by (software) applications. This is about partitioning the functionality implemented by a software system into a number of distinct components, services, subsystems, layers, workflows, etc. It's simple and intuitive. We strive for transparency and don't collect excess data. Do you understand the meaning of all line styles used? VP Online makes diagramming simple, with a powerful diagram editor, and a central workspace to access and share your work. More ArchiMate Diagram examples: Example 1 – Location (e.g. The factors that prompt me to draw class diagrams for parts of the software system include the complexity of the software plus the size and experience of the team. This diagram shows how the content updater is divided into components, what each of those components are, their responsibilities and the technology/implementation details. The Motivation Extension (Drivers, Goals, Requirements, Principles, etc.) Technology choices (or options) are usually omitted. We're a place where coders share, stay up-to-date and grow their careers. Do you understand what every element does? Annotating those boxes with responsibilities helps to avoid ambiguity while providing a nice "at a glance" view. Do you understand what the diagram scope is? (e.g. As illustrated by the containers diagram, includes a standalone process that pulls in content from Twitter, GitHub and blogs. Do you understand the type of every element? Do you understand the meaning of all colours used? ArchiMate distinguishes three main (Core) layers: The ArchiMate Motivation elements enable the modeling of stakeholders, drivers for change, business goals, principles and requirements. I especially like that you focused on how to review architecture diagrams.
