Task 1:

1 Define the term ‘use case' and explain the role of use cases in system analysis.
2 Explain the difference between the <<include>> and <<extends>> relationships in use case diagrams?
3 Compare and contrast between ‘Agile' and ‘iterative' methodological approach.
4 What is the difference between USDP and the Waterfall lifecycles in the relationship of between activities and phases?
5 Explain Class diagram. Outline the main steps in developing a class diagram for a Use Case(UC).

Task 2:

Task-2 of this assignment uses the Case Study based on an Interview contained in a separate document (Please see the details in page 221 of your text book). Carefully read this case study. You are required to answer the following questions based on the Case Study.
It is expected that answers to the assignment questions be succinct and MUST be written your own words.

Question 1: UC diagram
Prepare a use case diagram for the case study.

Question 2: Description of the UCs
Write a short description for the following UC:
• Start line run
• Record employee joining the line
• Record employee leaving the line
• Stop line

Question 3: Sequence diagram
