Software development- continuous deployment
I was delighted to read this post about the efficiencies of doing "Continuous deployment". My software company has been doing this for years with really good success. Of course we've run into problems from time to time but all in all our customers have been really happy with the process. They've gotten what they've needed at a fraction of the cost of traditional development.
I used to try and explain our approach by telling people that we followed an "Agile" development process or an "XP development" process but in reality we have been doing continuous deployment. They key is using principles that are rooted in continuous improvement processes such as Six Sigma and asking the "5 Why's" and looking at root causes.
