21st Century Business Logic:
1. Multi-task. Never devote your entire attention to one task when you could be juggling 7.
2. Run Lean. Why hire a dedicated expert developer, a dedicated sysadmin, a dedicated DBA and a dedicated network engineer? Make one person do all those things (see #1, above).
3. Run 100% and demand 110. Who needs expansion room for when things inevitably go pear-shaped? Which Murphy guarantees even when you don't tempt him with #1 and #2.
4. Run cheap. Demand maximum expertise from the lowest bidder. There's always someone in a third-world country who'd be GLAD to do items #1, #2 and #3 for pennies a day!
5. Use easily measured things to determine employee effectiveness. Lines of Code, Time on Phone, stuff that's easily objectively measured, unlike less tangible things like customer satisfaction (what, you think we bother to ANSWER those silly surveys?), externals (like poisoning 6 downwind countries) or time to do the job right the first time. Use these as weapons to demand more of #1, #2, #3 and #4.
6. Subscribe to overpriced buzzword-laden management fads to assist in accomplishing all of the above.
