How can architecture documentation standards improve your IT projects?

Standards ensure a common understanding and a common reference point for teams. As technology become complex with several dependencies and interdependencies, it is critical that organizations drive standardization. Having said this, it should not be made into precision science either. The key is to have architecture maps that follow a standard vs debate and spend hours on what the standard should be.

Contrary to what Walter Gropius said that, "Architecture begins where engineering ends," in the world of IT, “Engineering begins when Architecture ends.” In IT systems, you can not engineer (or build) something without architecting (or designing) it first. Engineering a system without proper architecture design would be chaotic , time-consuming, and one can not guarantee results. The main purpose of an IT architecture documentation is to share the logic behind a system’s design. Without it, it’s like putting the cart in front of the horse.

Business goals and team brainstorming are a prerequisite for documentation standards. By these steps , we will avoid many changes in he document

My experience is from environments where architecture documentation was sometimes present, sometimes not. And sometimes when it was, it wasn't socialized sufficiently. In these cases, engineering must take on the architectural design, which may depart from the multi-year strategy that exists (or should exist) within the architectural documentation. In the end, someone has to define the long-term strategy, standardize them so they are consistent, and social them with other teams that need to align to it (and provide feedback on it - this isn't a 1-way street). If you don't have a formal process for this, it means you're just hoping things will work out.

Availability of business applications is critical for any business. Thereby documentation of standards around architecture helps anyone managing projects / building solutions to use it as a reference architecture. Provided it’s proven for few years.

IEEE 1471: Foundational framework and terminology for software-intensive system architecture. ISO/IEC/IEEE 42010: Comprehensive framework for describing, analyzing, and evaluating system architectures. TOGAF: Extensive methodology for enterprise architecture development, management, and governance. ArchiMate: Graphical modeling language for enterprise architecture notation, analysis, and visualization. Choosing the appropriate standard depends on the specific needs and objectives of the architecture documentation project.

Imagine architecture documentation standards like ice cream flavors for your project. **IEEE 1471:** Classic vanilla, framing architectural descriptions for the big picture. **TOGAF:** Versatile chocolate swirl, covering the entire enterprise architecture. **Archimate:** Pistachio - a visual language, adding a pop of color to your documentation. **UML:** Neapolitan, offering various diagrams for a diverse documentation palette. **ISO/IEC/IEEE 42010:** Tutti-frutti, enhancing the quality of architectural descriptions. **Zachman Framework:** Rocky Road, a matrix organizing documentation based on who, what, when, where, why, and how. Each flavor adds a unique touch to your project sundae.

Various architecture documentation standards serve distinct purposes. IEEE 1471 frames terminology for software-intensive system architecture, ISO/IEC/IEEE 42010 covers any system's architecture, while TOGAF is an extensive methodology for enterprise architecture. ArchiMate, aligned with TOGAF, provides a graphical language supporting notation, analysis, and visualization with a metamodel and viewpoint mechanism. These standards offer flexible options for documenting and communicating architecture in diverse domains and organizational contexts.

It's paramount to select from the varieties of standards. Its application will certainly add to efficacy in all ramifications. * Architecture Decision Records (ADRs): Specifies the architectural decisions made by outlining the context, design process, and options considered. * IEEE 1471 / ISO/IEC/IEEE 42010: Core standard provides a framework for architectural description and defines key architectural concepts. * TOGAF: An extensive methodology for enterprise architecture governance, development, and management. * Unified Modeling Language (UML): For documenting software architectures standardized in visually representing system designs.

Choosing the suitable architecture documentation depends on factors like system complexity, audience, resources, and organizational standards. Those factors are key when assessing the project needs.

You need to choose architecture documentation standard based on your goal and area or context. Sometimes it also depends of type of tool being used from resource perspective.

Selecting an architecture documentation standard requires a tailored approach. Assess your system's complexity, intended audience, and purpose, considering factors like resources and existing organizational standards. Prioritize flexibility, scalability, and alignment with project needs. Engage stakeholders to ensure consensus, fostering effective communication and documentation practices.

Comprehensive sequential steps are essential in ensuring successful implementation across projects or organizations. This entails definition of goals and objectives, customization of specific needs, and establishing processes and workflows, for applying an architecture documentation standard.

For applying the architecture documentation standard its important that your goals should be very goals are clearly defined. Once the goals are clearly defined than creation or organizing documents should be done and review is must with your partner.

This also depends on the Framework that the company has chosen to work with, generally each Framework will have a guide on how to keep the documentation and how to create it.

Choosing an architecture documentation standard is like picking the right tool for a project. Define your project's scope and goals, identify stakeholders, and choose views that matter. Pick a language and framework. Organize docs, validate with stakeholders, and keep them updated as your project evolves. It's like creating a DIY masterpiece – plan, showcase, and adapt.

There are two biggest challenges in this process: determine the deliverables that are most valuable to the core businness and find who are the correct sponsors of this project. The first issue can be achieved by a meeting with the main stakeholders and the IT managers, that should determine which documents must have more time and effort dedicated to do and others that must be done, but with less depth. The second issue and the most important, is to choose the sponsors that really understand the value of the process of architecture documentation. You shoud have at least an sponsor from the technology area and one from the business area. In this way, you have both perspectives of the value that these documents can have to the company.

Universal buy-in is the most significant cultural challenge. The consistency has to not only be practiced by the architecture team, but also understood by all other teams in the ecosystem. Whoever is responsible for early cycle requirements gathering needs to ask the right questions so their input has value. Likewise, downstream customers of the architecture need to understand the language to effectively implement the solutions. This requires the architecture team to be passionate evangelists of the standards and language, within their work as well as the system context of the workflow.

It's key to not let the documentation for too long without being updated. Systems change and even tho you might know it your peers or newcomers don't. I recommend you to schedule this update based on your business needs so you always have the documentation up to date. Updating documentation is also a great exercise for someone new on the team. They will learn a lot about the system and have a global view of the past developments that they won't otherwise

Take a pragmatic and flexible approach. Prioritize the value and relevance of documentation for stakeholders, strike a balance between detail and brevity, and leverage automation and integration tools to streamline the process. Apply quality assurance and verification techniques to ensure accuracy and clarity, and adopt a lean and agile mindset, updating documentation incrementally as the system evolves. Seek feedback from peers and experts to continuously improve your documentation practices and address challenges effectively. This approach helps manage the cost, effort, and time associated with architecture documentation while ensuring it remains a valuable asset for your projects.

Architecture documentation can provide a clear and standardized way to communicate the architectural design and decisions to all stakeholders involved in the project. Documentation standards help in maintaining consistency across different components and modules of the IT project. By following a set of predefined standards, developers can ensure that the architecture is well-structured and organized, making it easier to understand, maintain, and modify in the workplace and enable better collaboration and knowledge sharing among team members. When the architecture is well-documented, it becomes easier for all to understand and be educated on before facing a barrier.

Documentation is not crucial only for a good understanding of the projects but is also very important to be clear and concise and support an incident solution during a crisis.

Consider your audience. Most of this stuff does not get looked at by anyone other than the author. General architecture patterns that can be adapted to a number of use cases are best. Infrastructure as code wherever possible is even better.

It is also important to note the evolution of architecture from being IT/Technical Architecture to more Business-Adopted Architecture. From my prior experience, I have first hand see the benefit of establishing and articulating the architectural vision (often led from a technology lens) to a business stakeholder audience. The understanding and acceptance by the business stakeholder group goes a long way with adoption since they are ultimately the internal owners and consumers of technology (prior to serving external customer base). Therefore considering the evolution and nomenclature usage to business-led or business adopted enterprise architecture might seemingly resonate within organizations.

Having proper Architectural Documentation of your IT Environment saves your company a great amount of resources when new projects are on the way. It would save you a lot of money, for instance, with procurement if you find out you already have an answer to your business needs right there under your nose.

When I assumed the role of a Principal Security Architect,. I quickly discovered the importance of documentation to gain consensus and guide the transformation. A service silo may have their own perspectives for the documents. A large enterprise may have another perspective. Use the framework that works best but remember that this is an overhead cost. One or two frameworks works better than hundreds. Last, if you are in an organization that has death by meetings with little tangible benefit, consider using an architect and their documents! You can lead a horse to water and eventually ALL will drink :-)
