The task class and skill hierarchy guide the other three components — supportive information, procedural information, and part-time practice. That is why I suggest you now improve the skill hierarchy to make better choices in the future. Remember that you should design and develop these three components for each task class. Again, as the first task class consists of very easy simulations, you could manage to design and develop the other three components. However, if you are not familiar with a field or designing a program for advanced students, you could need a practitioner's help.
