2. Chapter 2 Problem Analysis and Understanding User Needs
	Topics What we plan to accomplish Problem Analysis Steps Analysis Steps Stakeholders Definition of Actors Analysis Steps Bring out the requirements Interviewing Step A: Interview every stakeholder Step B: Requirements Workshop Requirements Workshop Organizing requirement workshop Brainstorming Brainstorming- Idea reduction Documentation Analysis & Focus Groups Interface analysis & Observation Prototyping Surveys/Questionnaires Step C: Identify Constraints Example - Given scenario Example (cont d) Registration system Problem statement Registration system Problem statement(cont d) List the stakeholders and users in the scenario List the actors Identify the constraints in the scenario Creating a constraint list

3. Chapter 3 Vision Document & Managing scope
	Topics Topics - cont d Vision document - Objectives Vision document - Scope Vision document - References Vision document - Positioning Vision document - Positioning (cont d) Vision document - User Description Vision document - Product Overview Vision document - Feature Attributes Vision document - Product Features Vision document - Constraints Vision document - Quality Ranges Vision document - Precedence and Priority Vision document - Other Product Requirements Vision document - Documentation Requirements Example of Vision document Managing Scope Define a baseline Example of itemizing list of processes or use cases Setting priorities Example - Setting priorities Assessing effort Example - Assessing effort Adding the risk element Example - risk element Get customer agreement on scope Use iterative development process Plan Change Request (PCR)

4. Chapter 4 Use Case Concepts
	Topics What are Use Cases? Benefits of Use Cases Use-Case Modeling An use case is a collection of scenarios To Use Case or not to Use Cases Use case modeling steps An Example use case Identifying the actors involved in this use case Write the use case for the above scenario Use case for the above scenario (contd) Classifying Use Cases A business use case Example of business use case (contn d) A system use case See notes Levels of use cases Examples of Summary level use cases Example of User goal level use cases Examples of Sub function use cases For use case modeling Use cases are only one part The Problem with Requirements Specifications Relationship Between Use Cases and Requirements Who are interested in use cases? General Principles Scenarios Primary Scenarios Example of ATM use case See notes Use Case interactions Finding Actors Finding Actors - continued Documenting Actors Where are the actors documented? The Actor-Profile table for the course registration system: Actor-profile table contd. Example Actor-goal list Goal List

5. Chapter 5 Use Case Modeling Use cases and supporting documents
	Topics Basic building blocks Basic Building Blocks of an Use Case Supporting documents Conceptual model Domain Model Non-functional Specification More use cases Documenting use cases Use Case Diagrams Scope The scenario we have been working on Identify the requirements that must be addressed by the system: Identify the use cases : Example - use case model Example - use case model for Registration system Lists used to manage scope In/out list for the above example Lists used to manage scope Actor/goal list for the above example Example - Use Case Specification Example - Use Case Specification (Contn d)

6. Chapter 6 Writing Use Cases
	Topics Actor Personalities Goal Levels Pre-conditions and Triggers Example of Pre-conditions Guidelines for writing flows Do's and don'ts" when writing use cases Extensions Use case linkages Sub Use Cases Example - Sub use cases with include & extend relations Quality Measures for Use Cases More Quality Measures See notes Who should write use cases? Fully Described Use Cases How much detail? Completeness & Complexity

7. Chapter 7 Use Case Formats
	Topics Formats to choose from Brief Description Format Bulleted Outline Format Conversational Format Narrative Format When to choose a format. Tools CASE tools Reviewing Use Cases Style Style Guides

8. Chapter 8 Miscellaneous Topics
	Topics Describing UI Wizards Make sure that the system is included Make sure that the user is included Wrong goal levels Make the use case easy to read Collect multiple pieces of data Do not forget the Exception Flows (failure scenarios) Stay away from internal system details Preconditions should be established by the system Proper use of UML CRUD Use Cases Contain the explosion Example - CRUD Use Case Specification Example - CRUD Use Case Specification (cont d)
