Musing: Generalist to Specialist and Back Again

Recently I’ve been musing on IT Generalists vs Specialists. We used to have more generalist roles, covering all parts of the stack. ITIL then pushed us towards greater specialisation.

HP IMC Silent Installation

HP IMC installation is normally a manual process, with plenty of clickey clickey clickey. This is OK for production systems, as most sites will only have one or maybe two IMC servers.

The New Zealand ISP market is dominated by Spark, Vodafone & CallPus/Orcon. A side effect of this is that if one player does the Right Thing™, it really moves the needle. Recently, Spark has done the Right Thing with DNSSEC.
