[QUOTE="pretzel_man, post: 594833, member: 927"] There are no allowances made for everything you mention. That does not mean that your last statement is true. Time studies are worked up initially based on "expected conditions". Not perfect conditions. The "expected conditions do not include the ones you mention, but.... This is an important but... After the base times are determined, an additional allowance is added. I don't know what its called today, but when I was taught, it was called PDF. Nearly 30 years ago I went to school at UPS to learn how to do original time studies. This is different than the ones I.E.'s do when they study you. A select few people were sent to school and we got a coveted "blue card" that enabled us to work up and original analysis. The last step of working up a study was to add in PDF. It used to be 15%. It was meant to account for many of the things not accounted for. PDF stands for Personal, Delay, and Fatigue. So, its not true that perfect conditions are expected. Its not true that no delays are accounted for. Also, as I have said before, work measurement is NOT meant to measure an individual driver for an individual day. PDF may be too little for you, and too much for a different driver. P-Man [/QUOTE]
