And, in fact, this section is a little anticlimactic. The code should be really lean. We'll start with the basics and then investigate add-ons little by little.

The Third Step: The Rough Framing of the Code

From a nerd-centric perspective, the following technique is perhaps one of the two most important statements in the book:

That means that the ElectroCard routing team (from Chapter 5) might produce these lines of code as one product of their architecture activity:

class CircuitGraph
end
def route(theCircuit)
end

or these lines if they are programming in C++:

#include "BoardLayout.h"
class CircuitGraph;
extern BoardLayout
route(const CircuitGraph theCircuit);

Remember these goals of Lean:

  • To avoid producing artifacts without end-user value;

  • To deliberate carefully before making a decision, and then to act decisively;

  • To create processes and environments that reduce rework;

  • To guide work according to overall consistency and harmony.

Lean architecture avoids producing wasteful artifacts simply by ...
