Here’s the annual reminder about the tyranny of numbers: Ranking looks at article traffic within a calendar month. As we post articles all month, this may give articles posted mid-month a disadvantage, since peak traffic may be split across two months. And some were very close in ranking. Number 21 in the ranking, “How to Choose Wireless Technology for Industrial Applications,” was within a few views of number 20, for instance.

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
