Researching a more efficient production process

To make your production line more efficient you need to break down those tasks into smaller and smaller tasks. For example the task to 'fit body' on our current production line is far too big. You can see how much time it takes by clicking on the slot itself (not the bit with the car on...) and that will bring up the following dialog box:The data that concerns us is at the top. It shows that although this production slot is described as 'fit body', it actually carries out a whole list of smaller sub-tasks (the top row of progress bars). Plus it takes 32 minutes (of game time) to do this!If these tasks are split into more slots car production flows much faster, and the overall processing time will be much shorter. How do we go about doing that?Return to the slot picker and expand the fit body option. A bunch more options break down this task into smaller ones. Currently all of these are locked! We cannot employ them until they are fully researched!To research upgrades at least one research office, which also employs scientific researchers, is required. The research office is inside the folder called 'facilities' on the slot picker:Place the research facilityon the factory floor. Note that although generally facilities can be placed anywhere, (they don't have to be anywhere close to, or connect to, the production line), in the case of 'office' facilities like the research office, they need to be placed in one of the green office zones on the map, so space is limited!Once you have a research office, either click on it, or use the icon at the top left of the screen to take you to the research and development screen. Select the 'Body Specialization' item, and begin the research. This will take some time, depending how many research offices you have. Be warned, they are not cheap. Also note that you need to produce a certain number of cars before doing this research, but if you wish, you could research something else while those ten cars are being made.Eventually, you will have access to those unlocked new production slots from the slot picker. In this case we have 3 new slots, Fit Bodyframe, Fit Roof and Fit Doors. Note that together (and in that order) these new slots will REPLACE the existing fit body slot. (You don't necessarily have to delete the old one, you can branch out and have one fast, and one slow production line).By replacing the single slot with 3 different slots, the production line will get longer, but will actually move. In time, you may have to demolish old slots to make room for a more complex line. Eventually, you can research every process tech and have a VERY long but VERY efficient car production line.
