Thinking Like an Architect

The Role of Architects
- Architects should strive to be "IQ amplifiers," helping others make better decisions rather than dictating them.
- Architects can help teams make better decisions by expanding their understanding of a problem's potential solutions.
Communication and Collaboration
- The most valuable architects are those who can connect different levels of an organization, facilitating communication and understanding between leadership and developers.
- Organizations with poor communication between leadership and development teams risk creating a "dangerous disconnect" where projects do not align with overall strategy.
- Effective communication, like using the "architect elevator" analogy, involves connecting technical details with high-level organizational goals, such as security, availability, and cost management, to facilitate better decision-making.
- Architects should use metaphors, particularly from the business domain they are working in, to effectively communicate technical concepts to leadership and foster understanding.
Architectural Considerations
- Layering, a common architecture pattern, offers benefits like separation of concerns, abstraction, and replaceability but can also introduce overhead, latency, and change propagation challenges.
- Architectural considerations, whether structural or operational, apply to both technical systems and organizational structures.
Decision-Making and Models
- Architects can introduce new dimensions to a problem, such as considering both the benefits and potential switching costs of cloud services, to help teams make more informed decisions.
- Rather than providing a single solution, architects can offer decision-making models that empower teams to choose the best option based on their specific constraints and goals.
- Good models are simple and abstract away from reality to provide clarity and improve decision-making.
- Architectural models should answer a specific question, and different questions will require different models.
- Uncertainty should not prevent the creation of models; in fact, models can be even more helpful in uncertain situations.
- Good architects understand that architectural decisions are not binary; they involve trade-offs and exist on a sliding scale.
Automation and Security
Platforms and Harmonization
- Enterprise Architects often prioritize harmonization, complexity reduction, and cost reduction, which can sometimes clash with the need for innovation and agility demanded by the business.
- Platforms offer a solution by providing standardization and harmonization while also fostering innovation, as demonstrated by the automotive industry's adoption of platform models, which led to increased product diversity.
- Software architects can create harmonization by standardizing APIs, interfaces, protocols, and data representation. This allows for diversity in programming languages and deployment options.
Uncertainty and Options
- Version upgrades have a switching cost, even in managed open-source projects, because moving from one version to another requires effort and resources.
- Uncertainty increases the value of options, such as the ability to scale up infrastructure or add capacity later. This is similar to the concept of options pricing in finance.
Architecture and Agile
- Architecture and Agile methodologies are complementary and both address uncertainty. Architecture provides direction and Agile allows for adaptation to change.
Fractal Thinking
- The world is a fractal, and understanding this is valuable because different perspectives on the same information can lead to different conclusions.
- Zooming out and looking at a system as a whole, rather than individual components, often reveals that problems arise from the interactions and assumptions between components, rather than within the components themselves.
- Architects should focus on understanding how system components work together and the overall behavior of the system, rather than just managing a list of components.
Models and Misunderstandings
- Some people believed that the Earth was the center of the universe, which is a geocentric model.
- Architects often try to explain things using their own models to people who have different models, which leads to misunderstandings.
Effective Sketches
- Effective architectural sketches, like those by renowned architect Frank Gehry, prioritize capturing the essence of a design, highlighting key elements, and incorporating context rather than getting lost in intricate details.
