I wouldn't say that there's a general rule. In fact, in many instances, you can arrange the stages in different ways, just as long as it makes sense.Stuti567 wrote: Hi Brent,
Thanks a lot for your wonderful explanation.
However, I have difficulties in breaking a task into stages. For example, in this question, why can we first select the model and then the color for each model? I understand that the variety of models is less than the number of cars to be selected still I don't feel very confident about it. Is there any rule or trick to divide a task into stages?
If we were to pick the models first, we'd need to consider several different cases: All three models are Model A, all three models are Model B, 1 model A and 2 model B's, ...and so on. As you can imagine, this get complicated pretty fast.
Once we see that this route isn't working, we might try a different approach.
Cheers,
Brent
