An interesting read.

One of the things missing about writing meaningful programmes is the need to 
employ a good deal of 'pre-thinking' in order to establish a suitable 
framework on which to attach your functionality.

Coding should be a minimal proportion of the overall project time, 
especially if it is Safety Related. I find that more than 60% of my project 
effort will be involved with the resolution of the Clients Requirements 
Specification into a document(s) that can be fully validated as early as 
possible. Less than 10% goes into coding and the majority of the remainder 
is mostly testing.

The Norris numbers are sort of interesting, but then 2,000 lines of Forth 
can become quite a powerful application. If done properly, it will not be a 
messy mass. Taking it beyond 2,000 lines will require a bit of a change in 
attitude and making it safe and dependable does require that lots of thought 
goes into its production.
