Design it like an organism

One of the clearest distinctions between mechanisms and organisms was given about two hundred years ago by the German philosopher Immanuel Kant. He described a mechanism as a functional unity in which the parts exist for one another in the performance of a particular function. The clock was the paradigmatic machine in his time. Preexisting parts, designed to play specific roles in the clock, are assembled together into a functional unity whose dynamic action serves to keep track of the passage of time. An organism, on the other hand, is a functional and a structural unity in which the parts exist for and by means of one another in the expression of a particular nature. This means that the parts of an organism – leaves, roots, flowers, limbs, eyes, heart, brain – are not made independently and then assembled, as in a machine, but arise as a result of interactions within the developing organism.

Always, have a picture of the whole – product or system – while designing, deciding and building. Understand, or at least have a theory of how each change or a new feature is going to affect the whole. There are a lot of techniques out there – design synthesis, design sprints, or prototyping – to visualize the whole. Better use them to not end up with a flaky mechanism.
