Throughout this chapter, we've built on the techniques that we've teed up in prior chapters and extended them to the application space. We positioned the key tasks through the lens of a process-based systems security engineering methodology (or at least the architectural elements of that discipline), rather than a purely enterprise architectural one. This lets us work within the constraints of the software development life cycle that our organization uses.
From here, we will start executing our architecture vision. Whether you created a vision at the enterprise scope in the previous chapter or created one at the application scope in this chapter, the next step is to lay the groundwork to put it into practice. This includes engaging subject matter specialists and engineers in key supporting areas and mapping out a technical architecture to support the higher-level, business-focused ones. We will do this in the next chapter.
