Please explain the meaning of the phrases in bold in the following two paragraphs:
I Accenture, which is increasingly offering Information Technology 9IT), business process outsourcing (BPO) and business consulting as a “soup-to-nuts” bundling strategy for its global clients, aims to double its management consulting staff across the world in about three years.
II. Women tend to quit such jobs (taxing ones, ie. 70 - hour week) after a few years, the study shows. Men often stay but more than 40 per cent who worked those hours experienced “brown-out” within a period of five years and had the tendency to their creative zeal.
To 'brown out' (or burn out) is what an electric lightbulb does at the end of its life (that is, the incandescent ones, with a filament that glows). 'Burn-out', a noun, refers to people having a glowing career and then losing their get-up-and-go entirely; I imagine 'brown-out' (not a noun I've heard) refers to a progressively unreliable performance.
