"A new crop of [business] buzzwords usually sprouts every three to five years," says the paper, as it offers up some of the latest, freshest produce.
delayering: has nothing to do with cake. It's the up-to-date euphemism for 'firing', f/k/a rightsizing or downsizing.

skills development: corollary to knowledge acquisition: putting new skills into existing employees
unsiloing: cooperation across departments and functions, such as sharing resources, cross-selling, etc.
execution: older term now back in vogue, replacing previous emphasis on 'strategy'
volume-sensitive business: one with high fixed costs
How in the world did someone come up with unsiloing? The only thing I can figure is that a silo is used for storing (usually grain), so siloing is used as a verb meaning storing (or hoarding), and unsiloing is not storing, or sharing.
