        Enrollment Management Model
Important questions for project success
Project deliverables, activities, milestones

What are the 4 P’s? Which is the most important and why (back up your perspective)?
*** Given a particular situation how should a project leader respond.
Describe the role of the project leader.
Describe the relationships between the producer, customer, and end-user as it relates to
software engineering.
Discuss the MOI model of leadership and how it can affect the productivity of a
development team.
The ______ metrics are best suited for object-oriented applications.
If you can’t measure it, you can’t ______________ it.
Define, compare, and contrast KLOC and FP metrics. What are pros and cons of each?
________________ = available time - real time.
With a large number of unskilled workers, the ______ organizational paradigm would be
most appropriate.
A software’s context, information objectives, function, and performance expectations
determine its ______.
What are the 3 strategies for avoiding risk?
What are questions that a project manager should ask when evaluating the project risks?

How can a risk management plan improve the outcome of particular project and the
Name some generic categories of risk. Provide examples of each.
The ______ team structure has no set leader though there may be task coordinators.
The ______ team structure may be useful for innovation but may lack the structure to
foster orderly performance as required in some projects.
The ______ team structure retains some of the control of the closed paradigm while still
fostering some of the innovation that occurs in the random paradigm.
A ______ type groups structure a team along traditional hierarchy of authority.

Chapter 4: Requirements and software quality assurance
Requirement: a feature of the system or a description of something the system is capable
of doing in order to fulfill the system’s purpose
Three kinds of requirements:
       those that absolutely must be met
       those that are highly desirable but not necessary
       those that are possible but could be eliminated
Requirements definition: complete listing of what the customer expects the system to do,
includes general purpose, background and objectives of system, description of customer-
suggested approach, detailed characteristics, and operational environment.

Relationship between software developers and users/customer (sometimes troublesome)
Requirements specification: restates the definition in technical terms so that the designer
can start on the design
Functional vs. non-functional requirements
Formal Technical Reviews: meetings (cost-efficient), roles, and guidelines
What is the purpose of Formal Technical Reviews?
Software configuration management
Software vault
SCM terms: release, revision, baseline, version, variant (alternative to a particular
version), version control, build, deltas, engineering change order, engineering change

Sample questions:
Define requirements definition and requirements specification.
How would assist customers and software engineers in having an effective working
What are the roles of the participants at a Formal Technical Review?
What is the role of a SQA group? -or- What is the purpose of SQA?
Name 5 guidelines for FTR.

Chapter 5: Designing the System
Decomposition and modularity

3 levels of design: architectural, code, executable
Design issues: modularity, collaboration, user interface, and reusability
Characteristics of good design: loose coupling, high cohesion, fault prevention
UML (class notes)

 State diagrams, activity diagrams
 Use cases and use case diagrams

Sample questions:
What is the difference between analysis and design?
What are the two styles of Architectural Design documents and how do they differ?
Name three design levels and describe each.
     architecture - associates system components with capabilities
     code design - specifies algorithms and data structures for each component
     executable design - lowest level of design, including memory allocation, data
   formats, and bit patterns
Describe 4 UML diagrams and what they are used for.
Define cohesion and coupling.
When a module performs one and only one well-focused task the module possesses a
