includes all key events; you should also

complete Data fragment for each event

identified. A levelled set of

dataflow diagrams for

this system

5: thoroughly done and correct, attention to detail, maybe a few small errors

4: good work, some errors but nothing major

3 overall OK but significant flaw in understanding or many small errors

2 generally on the right track but significant multiple flaws in understanding or omissions

1 really off track and would require a major rewrite virtually from scratch

0 not attempted

Bonus Point earned (up to 5 marks): For the Bonus mark, we will look for the following:

• Provide an excellent report or models;

• Complete additional tasks to fulfil the assignment, such as a very detailed problem analysis,

functional or non-functional requirement……;

• Demonstrate a sound research effort via high quality of references.

All the above will be discussed and decided by the teaching panel. We will mark on quality not

just quantities.
