Advertisements And that was my point that there is HARD work involved if the work is hard, even if the steps are easy to define and are known ahead of time, the task itself is difficult. Listing the steps to accomplish it is easy, but the actual work is (or can be) hard. For example, I work at NASA. I could sketch out a very simple flow diagram that explains the basic steps to assemble the solid rocket motors for a Space Shuttle Flight. The problem is the actual work is VERY difficult and relies on highly trained people to pick up a 180,000 lbs rocket segment and position it to within 0.025" lower it onto another 180,000 lbs segment and maintain rates of engagement less than 0.060" per second. and that's the easy part we have nice big cranes to do the lifting.
