I've heard some argue that we shouldn't be allowed to request engravings of specific things because it is too much like mind control. I agree with this to an extent. However, there are a number of elements in the game that amount to almost the same thing, for example the ability to tell dwarfs exactly what to furnish a room with and where to place it. I think the game would play more smoothly if there was a consistent level of control over the dwarfs in all tasks. (For example: you should only be able to control the metal a door is made out of if you can control the stone it is made out of.)
For the sake of simplicity we can divide the possible levels into three broad categories:
Micro-managing boss: This is currently what we have with most tasks - you can give your dwarfs extremely precise instructions and expect them to follow them exactly. (you, legendary craftsdwarf, make me a bin out of copper (by setting who can work at the shop)) If that is what we want then we should, for the sake of consistency, get control over what stone things are made out of, what an engraver carves, and a decorator decorates (you there, carve me some carp). Personally I don't like this level of control because it usually is more work than it is worth. For example, I generally order things through the manager screen because I find messing with individual workshops to be pretty tiresome, especially when you have to go through several sub lists, like at the forge.
Town mayor (or a good boss): Manages by setting goals, leaves details of the implementation up to the workers. For example, under such a level of control you might designate an area as a room of a specific type and then instruct your dwarfs to furnish it to a certain level of opulence. The dwarfs themselves would then determine what to furnish the room with and where to place it, generating jobs to make items if needed. A large room would get more beds / tables and chairs than a small one would. Similarity, you would tell a dwarf to join the military; he or she would pick their own weapon and armor based on availability, personal preferences, and the composition of the existing military. A request to make some armor would result in an available artisan producing a full suit; the type being determined by available materials, personal preferences, and skill (only the better dwarfs would attempt a suit of plate armor). So for most tasks this is a bit more abstract than we currently have. Also the need to order the production of intermediate goods (such as potash) would probably vanish.
King: Manages by setting long-term objectives. This is probably not a good option for DF, but it's good to have in mind as an extreme. In such a control scheme you would set, for example, the percentage of labor and resources that should go to the military, and dwarfs would manage themselves accordingly. This would probably leave the player with too little to do.
