The work triangle described was made famous by Lillian Gilbreth's
(of Cheaper by the Dozen fame) use of it in laying out the galley
kitchens. In a kitchen, the cooking sequence went from refrigerator
to sink/prep area to stove.
Refrigerator sink/prep stove When cooked, the food and utensil went
back to back to sink/prep or refrig..
By using cabinets to hold the utensils around the prep/stove area,
she was able to make an efficient work space. It is a simplification
of the string method of determining proper layout of a task sequence.
You can use the same methods to determine how to layout your work
area: Get a ball of twine and tape and a marker. Start making a
typical something. Every time you change area, tape the string down
and number it. Be careful! Don't make a costly item, because you
will have a spider's web as you cross over and back and forth doing
things!! If you are being very detailed, also note when you change
tools and supplies.
When finished creating, look it over your area. If possible,
diagram it (a standard layout diagram is done on quarter inch paper -
put in windows, doors and nonmoveable items - make a to scale master,
diagram the string bit on a copy) or take a picture or make a
drawing. Then analyze it. (if you made a layout diagram, you can make
scale models of stations and move them around. Some software does
this stuff also) The objective is to lay things out using as little
space as possible without crossing over too many times. (Purists say
you should never cross over, but I never got that to work) If you
did note the supplies, see if you can build in cabinets above, below,
or beside to hold them where they are used. (Yes, it is common sense
but then this method is very old.) If you are interested in that
sort of thing, look up work simplification methods.
