Executive promotion/bonus lifecycle
[1] pick business function(s) to outsource; friends who run outsource firms can help, and later provide favors, kickbacks, and/or references.
[2] present financial figures (generated by friends in [1] above, from delusional optimism and marketing materials) that show substantial (usually unrealistic) cost savings; ignore or dismiss any mention of functionality or service levels (those can be invented later); add huge doses of marketing-based fertilizer.
[3] sign outsource agreements; put previously invented cost projections into future budget(s); inform everyone of stunning success, and watch the share price spike (note - flip stock options).
[4] collect bonus and/or receive promotion (and soonest, before the real consequences begin to manifest - in a big company, this will hopefully take some time); MOVE ON (this becomes important later).
[5] as the cost savings prove illusory, and the functionality, quality and flexibility of services plummet (this is normal in outsourcing), blame the implementation ("behold the incompetence! i would have done it differently..."); assert that your glorious vision was mishandled (note - good time to sell short).
[6] as former employer desperately scrambles to insource the function(s) outsourced by your initiative (note - stock price will fall, buy low), evaluate current employer for the same sequence (go back to [1]).
...rinse, repeat.
