How Architects Evolve: From Technical Expert to System Architect
This article outlines the core stages of product development, details the architect's responsibilities across these stages, and presents growth and competency models—including the Chuck Kilmer model—illustrating how developers transition from specialists to full‑system architects while emphasizing the need for broad skills and experimentation.
The product development process can be divided into several core stages: customer‑facing process, product planning process, optional product line development process, product development process, and personnel and technology management process.
The main responsibilities of architects in each process are as follows:
The architect growth model, Chuck Kilmer model, is shown below:
The growth curve for developers transitioning from technical experts to architects is shown below:
It can be seen that architects undergo a shift from depth to breadth: first mastering a technology to become a technical expert, then broadening knowledge to become a multi‑technology expert, then a subsystem architect, and finally, through accumulated experience, a software system architect.
The architect competency model is shown below:
All engineering progress builds upon a series of failures, gradually maturing into success. In software architecture, one must be willing to experiment while possessing comprehensive skills to reduce the likelihood of failure.
