Describe the process of identifying the BOs.
What are the differences between EBTs and BOs?
T/F: The product of the first-level abstraction is design.
T/F: The product of the second-level abstraction is architecture.
What are the differences between SAPs and traditional analysis patterns?

Apply the Negotiation pattern to purchasing an item online.• Draw a class diagram of using negotiation patterns to purchase an item online.• Generate a significant use case for this context.• Map the use case to a sequence diagram.
List the properties of EBTs and each of the properties as Stable Analysis Patters.
For negotiation stable analysis pattern.a. Name a few context of negotiation.b. Use one of the context and draw a class diagram.c. Document a detailed and significant use case selected context in b.d. Create a sequence diagram of the created use case of c.
For trust stable analysis pattern.a. Name a few context of Trust.b. Use one of the context and draw a class diagram.c. Document a detailed and significant use case selected context in b.d. Create a sequence diagram of the created use case of c.
Explain and define Pattern.
Define generality. Why is it important?
Define traceability. Why is it important?
“Satisfying both generality and traceability is a factual challenge in current analysis patterns.” Explain why.
Can generality be achieved if pattern as developed as templates? Justify your answer.
Why developing patterns as templates sacrifice their traceability?
What problems arise if analysis patterns are used through analogy? Explain.
Explain stability model.
What are the three layers of stability model? Explain with the help of a diagram.

Draw and explain negotiation stable model.
What are the participants in negotiation stable model? Explain.
Justify the existence of the following classes in negotiation stable model.a. AnyAgreementb. AnyMediac. AnyContextd. AnyParty
Why is prefix “Any” used in front of the class names in negotiation stable pattern?
Apply the negotiation stable pattern to buy a car. Draw a class diagram for the same.
Explain content negotiation using CC/PP. Draw a class diagram for the same.
Explain the advantages of stability model over analogy approach.
Explain how traceability and generality is achieved using stability model.
“Each object in the negotiation pattern has a clear role, independent of the application the pattern will be used in.” Explain and justify.
Compare stability approach with analogy approach.
Model your dream vacation by using analogy approach and stable approach. Which one do you like more and why?
Model your dream house by using analogy approach and stable approach. Which one do you like more and why?

Try to identify the class in the stable design pattern for culture.
Try to connect those classes together to form a class diagram.
Try to find 2–3 scenarios where this pattern can be applicable.
Consider a scenario where your laptop has stopped working and you take it to a repair center. The vendor asks for a huge sum of money, but you negotiate with him the price for repair. Create a class diagram for this using negotiation patterns as your base and draw a sequence diagram for
Consider a scenario where you negotiate with a company over the salary and perks being offered for a position. Create a class diagram for this using negotiation patterns as your base and draw a sequence diagram for negotiations.
Consider a scenario where an online trade application is being developed. The two registered users can negotiate over the price of a product being traded. Create a class diagram for this application using negotiation patterns as your base and draw a sequence diagram for negotiations.
Explain main disadvantages of starting analysis from scratch for each project.
What does a pattern represent—a complete system or a specific commonly occurring problem?
List eight essential properties that influence usability and effectiveness analysis models. Give brief description for each property.
What are the three foundation concepts of stability model?
Give a description for three foundation concepts in stability model.
Describe three main steps to identifying EBTs.
(T/F) EBTs should have a direct physical representation.
Where do you start developing BOs for any particular EBT? What questions do you need to ask?
What criteria do you use to filter the list of BOs?
What are the four characteristics that a BO must satisfy to fully qualify as a BO in any particular pattern?
What characteristics do you check for each BO?
How do you apply a stable analysis pattern to a particular context?

Use the Any Entry pattern to model entries in a spreadsheet style application.a. Draw a class diagram of using Any Entry pattern.b. Generate a significant use case for this context.c. Map the use case to a sequence diagram.
List and explain essential properties of analysis patterns.
“A pattern is not intended to represent a model for a complete system.” Explain.
Why is it important that each pattern must focus on one specific problem?
Why is it important to decompose a system into individual components?
“If a pattern is used to model an overly broad portion of a system, the generality of resulting pattern is sacrificed.” Explain with the help of an example.
Explain why a pattern representing rental system will not be complete and accurate.
What are the key characteristics of a model that makes it easily testable?
List advantages of stable models.
Why is graphical representation of a model important?
How is applicability of a pattern related to pattern reusability?
What are the two categories of pattern generality? Explain.
Why is it important for a pattern to present the core aspects of a system?
Explain the classification of analysis patterns based on the methodology of construction. Briefly describe each category.
What is the concept behind constructing an analysis pattern by using direct approach?
What are the drawbacks of constructing analysis patterns using direct approach?
What is the concept behind constructing analysis pattern using analogy approach?
“Analogy approach makes people end up building templates rather than building patterns.” Explain.
Explain the concept behind constructing analysis pattern by using stability approach.
What are the advantages of using stability approach over direct and analogy approach?
