The comment is definitely with regards to businesses and with regards to advances made by the business as seen by stakeholders.

I did not intended this to apply to anything else.

I may have made an error in my post, though. Making unpredictable progress is not lethal in itself if you can show steady progress. It should have probably been worded "lack of steady progress is lethal to businesses". It is ok to have some unpredictable projects as long as you can build trust with steady progress somewhere else in sufficient quantity.
