2. MidTerm 2 Question List

3. Describe defining characteristics of open source software development.

4. Characteristics of Open Source Software Development
Software made available, for free, in executable form, access to source provided
Small releases- Frequent (Few months to few years)
Informal, written communication using Internet tools
Customer Availability- Developers are initial customers
Continuous Integration through Internet tools
Requirements may change, collected informally
Informal and iterative design
Minimal documentation- relies on source code
Possibly large distributed teams
Scaling

5. The Mythical Man-Month, to help you as a junior member
How could you use
Brooks’ Law,
from
The Mythical Man-Month,
to help you
as a junior member
of a software development team?

6. Causes for scheduling disasters
We expect that all will go well.
We confuse effort with progress,
and think that people and months are interchangeable.
Managers are often insufficiently stubborn.
Schedule progress is poorly monitored.
When schedule slippage is recognized, more people are added.

7. Brooks’s Law: Adding manpower to a late software project
makes it later.

8. You are a Junior Developer

9. values of the “agile” approach to software development are violated by
Which,
if any,
values of the “agile” approach
to software development
are violated by
the Waterfall Model?

10. Values of Agile Approach violated by Waterfall Model
User Involvement
Agile -needs users to be involved to provide constant feedback
Waterfall- Limited interaction with users- only requirements phase & delivery
Documentation
Agile- Minimal
Waterfall- Heavy (requirements, design & testing)
Short releases and Iteration
Incremental Design

11. Draw a UML Class Diagram for WebReg.

12. Requirements for WebReg
You may use WebReg to enroll in classes and make schedule changes during both the Enrollment by Window and Open Enrollment periods.
Once logged in to WebReg, you will be able to:
Add a class (through 2nd week of instruction)
Drop a class (through 2nd week of instruction)
Change the grading option of a class (through 2nd week of instruction)
Change the unit value of a variable unit course (through 2nd week of instruction)
Use the waitlist option until waitlists are deactivated
View co-classes
List the open sections of selected classes
Receive confirmation of successful enrollment transactions
Receive error messages for unsuccessful attempts to add, drop, or change enrollment
Be notified of any academic holds on your record
Verify your registration fee status
As an undergraduate, you may enroll in as few as 12.0 units or as many as 20.0 units per quarter. However, undergraduate enrollment will be limited to 18.0 units until WebReg reopens after the fee payment deadline.
The status of a course indicates the seat availability in that particular course.
A UCInetID and password is required to use WebReg.
These requirements may be more complex than what you know about WebReg. Make the class diagram as per what the question mentions, and what you know with respect to it.
