The job that is needed is basically customer check-out process. What we need is the ability to allow customers to build their own speaker boxes. Meaning the customer can select the unit they want and then the process would have them select an available stereo system that will fit in the that box. Once they have selected their stereo then it will bring them to the speaker section they will then be able to select the speakers they want. The final step will be accessories. Once they have selected accessories then they can check out.
I have attached a storyboard document that explains it in more detail. Please remember that not all speakers and all stereos will work with all boxes. So the admin will need to be able to load the products by category.
