In the paper we examine one of the issues in designing, specifying, implementing and formally verifying a small operating system kernel --- how to provide a productive and iterative development methodology for both operating system developers and formal methods practitioners.

We espouse the use of functional programming languages as a medium for prototyping that is readily amenable to formalisation with a low barrier to entry for kernel developers, and report early experience in the process of designing and building sel4: a new, practical, and formally verified microkernel.
