Notes:

[1] Note that leaving the instance name blank can represent anonymous and unnamed instances.

UML Notation of the instance

 instance name : class name 

[2] From http://en.wikipedia.org/wiki/Sequence_diagram

In order to display interaction, messages are used. These are horizontal arrows with the message name written above them. Solid arrows with full heads are synchronous calls, solid arrows with stick heads are asynchronous calls and dashed arrows with stick heads are return messages.

Activation boxes, or method-call boxes, are opaque rectangles drawn on top of lifelines to represent that processes are being performed in response to the message.

When an object is destroyed (removed from memory), an X is drawn on top of the lifeline, and the dashed line ceases to be drawn below it (this is not the case in the first example though). It should be the result of a message, either from the object itself, or another.

A message sent from outside the diagram can be represented by a message originating from a filled-in circle.

[3] What is the difference between a signature and a contract?
(Motivation for Operating Conditions)

http://www.cs.rit.edu/~afb/20012/cs4/slides/contract-04.html

Sequence Diagrams indicate the signatures and the return types;
However, the "operating conditions / contracts" outline the contracts

Also, see hierarchy of contracts
http://www.cs.rit.edu/~afb/20012/cs4/slides/contract-05.html

Extensions are obliged, however, to fulfill the contract of their base classes. Hence, contracts must not be weakened by extensions.

RUP artifacts

Artifact Sets in each of the RUP disciplines are given. And for each artifact, the standard templates are also provided.

Scrum, Spiral, XP, RUP and Waterfall models

[1] Scrum

[*] Comparison of RUP and DSDM in the context of Testing
RUP as a buffet - Do you want heavy or light?
RUP as garage or basement - because there are artifacts, we tend to hoard these

[*] Introduction to RUP
Good information on how much %age of schedule and effort are spent in each of the phases.
Also, the outline of the presentation is presented in terms of the I, E, C and T (like RUP). That is creative

NOTES:

[1] Use Cases are described in terms of the language of an end user (customer).
Analysis Models are described in terms of the language of the developers.

Requirements: Do the right thing
Design: Do the thing right

Boundary Classes (actions, widgets)
Entity Classes (domain objects) and
Control Classes (C in MVC)

[*] To illustrate a problem with the waterfall model: Suppose I estimate that the project will take two years, and it really takes three years. At the end of two years, what do I have? Nothing useful works. No partial delivery is possible. Diagrams and models are great, but they can not execute.

[*] Waterfall is conceptually straightforward because it produces a single
deliverable for each step (requirements, analysis model, design model,
code, etc), resulting in a single release. The fundamental problem is that
it pushes risk forward in time, where it’s costly to undo mistakes from
earlier phases. An initial design will likely be flawed with respect to its
key requirements, and furthermore, the late discovery of design defects
tends to result in costly overruns or project cancellation. The waterfall
approach tends to mask the real risks to a project until it is too late to do
anything meaningful about them.

[*] Interesting site http://www.monstersdlc.com/ The site is developed as RUP phases

[*] Waterfall Model is also called Staircase model

[*] All development processes are (a) plan driven (heavy weight) or (b) evolution driven (light weight) or (c) a combination of both
