The act of architecting requires sufficient knowledge of a system to frame useful hypotheses about quality attributes, and the expertise to write code and devise tests (or work closely with team members who can) that can evaluate those hypotheses.

Software Architect is not some sort of honorarium for people who have retired from active development but still have knowledge the organization finds useful it has to be more. This is also one reason why software architects must still be developers they can’t understand or predict the forces at work in a system without developing and testing something. As an old saying goes, good judgment comes from experience, most of which comes from bad judgment.
Knowing what was tried and rejected is often more useful than knowing what worked. The reason for this is that architectural decisions in software are rarely clear-cut nearly every architectural decision is a compromise between competing alternatives, and the merit of alternatives is hard to see until you try a few and see how they work. What they did should be easy to see in the code, if it is well-organized and commented on, but the why is often lost. Knowing why someone did something is just as important as knowing what they did. It’s not that structure and behavior are unimportant, but they are the results of a thought process that is important to preserve if the system is to sustainably evolve over time. The building analogy has led some software architects to focus too much on structure and behaviors, and not the decisions that produce those structures and behaviors. Achieve extreme scale with the lowest TCO. ScyllaDB is the database for data-intensive apps requiring high performance + low latency. Software architecture is about decisions, not structure Not so in software, where how something is built influences what is built, and vice versa. Design and building have become separated. That sense has become lost in the work of building architects, many of whom have never poured a foundation, framed a building, or run plumbing or heating pipes. Architecture is created by people building things. To arrive at a better understanding of software architecture, we have to go back to the origins of the word architect: It comes from the ancient Greek word arkitekton, ἀρχι- (arkhi-, “chief”) + τέκτων (téktōn, “builder”). Software, by its nature, is ever-shifting and dynamic when it stops changing, it starts to die. Buildings are static, and the work of building architects is done just once. But the work of architecting software systems is far more dynamic than the building architecture metaphor supports. Inspired by the work of building architects, the word conjures images of beautiful designs that hint at utopian futures. Part of the problem is that architecture is an inapt metaphor for the result of the work of architecting software systems.
So is there a useful middle ground between these poles of pointlessness? In the experiences of many, it is the cause of valueless meetings and irrelevant documentation that is aptly summarized by the expression “the map is not the territory.” And yet, applications with poor architecture can quickly become like vehicles abandoned by the roadside, broken and unrepairable. Software architecture has a contentious reputation in the agile community.
