Above and beyond a simple list of waza ...
In my book I advise to work on hard training for a long time before switching to soft training. What I mean is, hard training against resistance and determined attacks is 100 times more effective and prepares one with an excellent base for soft training. You cannot easily do this in reverse. To be effective, in your early Aikido days, up to say Shodan or beyond, training should focus mostly on overcoming resistance - hard training. Also, one should concentrate on developing fitness and power. Of course, some softer training is always in order, but you cannot really focus on such full-time until the hard training 'restructures' your body.
What does it mean to be Shodan? We make far too much of this in the West. In the East, the Shodan has learned all the basic techniques and is ready to move on. In the West, the Shodan will typically have trained longer and harder. I prefer to think of the learning process along three simple levels.
Incorporating learning in a syllabus
Note 1: The above is a very different approach to what most Aikidoka would think of as being a syllabus. My suggestion is to try and incorporate 'method' into the 'structure' of your syllabus.
Note 2: Next time you watch a high grade throwing uke about with ease, check and take note of how hard, or not, uke is really trying to grab and/or clobber tori. Most ukes just fly because they feel they are supposed to. I am suggesting you build some sensible resistance into your syllabus, or at least, your training regimen.
