Build a basic piece of software with a rich web interface. Capture some details of a product, and a tray, along with a picture of each. These using good interface design the user can check that the tray conforms to the instructions provided.
I don't have a language / software preference. It just needs to be scalable, and supported for web hosting.
I am following an Agile concept and have prioritised my requirements. So, this is the first iteration of what will be many.
Please refer to the attached files for the rest of the details. If you have any questions at all please ask.
I have also included a demo app to give an idea of how it works and the interface ideas.
