Here’s a view from inside Tesla by one of it’s former employees. Taking the report at face value, which is of course an arguable proposition, you can see how technical debt can build up to a point where it’s near impossible to pay it down. That in turn can have significant effects on the safety performance of the organisation, see the Toyota spaghetti code case as another example. The take home for this is for any software safety effort it’s a good idea to see whether the company/team is measuring technical debt in a meaningful fashion and are actively retiring it, for example by alternating capability and maintenance updates.

There also appears to be a community of like minded spirits out there who are intent on seeing how far they can push the automation… sigh.  Continue Reading…
