  * Despite what it superficially looks like in (for example) Sariel's build videos, having a big pile of parts spread across the table is not the fastest way. Pour the contents of the smaller bags into containers (I use old plastic take-away containers). That way you are looking through a container of blue 3 long pins and red 2-long axles for a 2-long axle, rather than rummaging through a mound of everything. I tend to pour the black 2-long connector pins onto the build space because there are so many and that way they're close to the build, but everything else goes in a container.
  * A little time sorting will help a lot. Sort things like beams and large parts, but also axles if there's a lot of them. Having a row of beams sorted by size and getting a 9 long one is much faster and easier than rummaging and comparing randomly grabbed beams for length.
  * I find pulling out really large parts early makes things easier. Wheels/tyres, power functions, large panels etc. A stack of 5x11 panels is easier to deal with than when they're randomly in a container hiding little parts underneath them.
  * I find piling the parts to be used in a step up, then installing them avoids missing any. If you need to add 3 axles, but you have one left over at the "end" of that step... you missed one. This is less necessary with modern kits because you put so few parts in per step, but still occasionally helps.
