As a technical authority, part of the responsibility is to analyze the options available and determine whether something can realistically be implemented. Possibility is not only about technical feasibility. It also involves understanding whether the business can support the solution and whether the team has the skills required to build and operate it.
But possibility alone is not enough. The next question is if it is scalable. Many ideas look correct in paper. However, that does not guarantee they will scale. A scalable solution is one that can support growth, evolving requirements, and increasing operational demands without introducing technical debt.
Then comes security. An architect does not need to be a cybersecurity specialist in every domain, but it is important to understand the principles that make a solution secure. Just as important is knowing when to collaborate with security experts to validate important decisions.
Finally, there is correctness. A solution can be possible, scalable, and secure, and still not be the right one. Architecture is ultimately about choosing the right trade-offs for the context of the enterprise.
