Reading assignment: Chapter 3

Homework must be neat and readable.  At the top of every page you must include your name, the assignment number, and the due date.  Clearly indicate the question you are answering. You do not need to copy the entire question, but you must mark the question number and a brief description at the beginning of your answer for each question.

For Assignment 3, you created an operational concept for a self-checkout system.  

1. Use the operational scenarios you created for Assignment 3 to define functions and ICOMs for the self-checkout system and the external systems with which it interacts.  Enter your functions and ICOMs into CORE.  Use a consistent numbering system for your functions and ICOMs. Use the description field in CORE to describe your functions and ICOMs.  Using CORE's generic table output script, produce a table containing  the items you defined and their descriptions.  Repeat for the functions and components you defined.
   
2. Use the "input," "output," "trigger" and "performs" relations to connect your ICOMs to the functions you defined.  Use CORE's generic table output to produce a functions and ICOMs table.  This is a table that has columns for function,  inputs, outputs, controls (triggered by) and mechanisms (allocated to).
   
3. Produce an external systems diagram -- an IDEF0 diagram showing the self-checkout system interacting with its external systems.   Print and hand in your IDEF0 diagram, clearly labeled with your name.
4. Write an explanation of your IDEF0 diagram.  Explain the functions performed, the systems that perform the functions, and the flow of items.  An intelligent non-engineer should be able to read your explanation, look at the diagram, and understand the basic concept for how the system works.
   
5. Print an element-relation diagram for your main system function F.0.  Make sure it is clearly labeled with your name.
