[FedCom] Interoperability Hamppers Agencies

[Michael Rumberg]

My apologies for any offense my writing style caused.  I was not intending to say or imply you the writer was lying.

Rather, the phrase "gives the lie to" was not pointed at you; I just meant that the theory of more complexity equals more failure does not hold true.  My larger point being better planning equals better performance.  The space program and modern aircraft being the most obvious examples.

Your point of system redundancies is well taken.  At the same time it also shows my point of better planning 9by including redundancies such as another poster pointed out in this same thread) reduces downtime.
