Ans. Extends is a relationship shown by a dotted line. It is usually used to specify optional behavior that has no independent meaning.
Extends adds one use case to another step to a first-class use case. It is used when one use case does not make sense without the other use case. This because it is an extended version.

Ques.40. Name the two documents related to a use case.
Ans. The two documents are-
1. FRD (Functional Requirement Document)
The FRD serves is similar to a contract. It includes the requirements of the application and the developers agree to fulfill them. It is an official document.

Ans. The verification and validation of the V model is a sequential way to process the testing and development phases. It shows how testing and development can go hand in hand.

Ques.46. What is the Fish model?
Ans. In the fish model both, validation and verification are done parallel, but by different teams in each phase. This is one of the reasons it might end up being expansive. The structure created of this model looks like a fish. Thus the name.

Some of its characteristics are-

1. Each phase is tested and reviewed by other people.
2. Due to regressive testing and reviewing, the fish model proves to be more expensive.

Ans. The JAD stands for Joint Application Development. It involves the user/client in the complete design and development phase from start to end.

Ques.50. What is ETL?
Ans. ETL stands for Extraction, Transformation, and Load. It is a data processing method mainly used in data warehousing. It is a recurring activity (daily, weekly, monthly) of a Data warehouse system.

In simpler words, it extracts data from various sources. Perform a few processes on them in the staging area (like calculations, concatenation, analysis, etc.). And then finally upload the whole thing in the data warehouse.

Ques.51. Do you think testing knowledge required as a business analyst?
Ans. Yes, although the job profile requirements are different. However, to make sure the products meet the expectations of the end-user BA is required to be involved in each phase of testing to validate it.

Ques.52. Explain Black Box Testing.
Ans. Black box testing is a type of testing where the entire unit is tested as a whole. Here, the tester only checks the input and the output of the system, nothing about the technicalities of the system.

Ques.53. What is a Kano analysis?
Ans. The Kano analysis is a graph used to analyze customer requirements. It is used to measure satisfaction, needs, and what the client wants.
It gives precisely what the customer actually wants. And, how the requirements will be fulfilled.

Ques.54. What do you know about scope creep?
Ans. Scope creep is also called requirement creep. It means uncontrolled changes in the project’s scope without increasing the resources like schedule, budget.

Customer needs do change over time. Delivering a project that answers their needs often means altering the scope. Therefore scope creep is a reality that every good project manager expects and plans for.

Ques.55. How can you avoid Scope Creep?
Ans. Scope creep can be avoided by using the following measures.

1. Plan and document all the requirements before starting the project. This will help in avoiding unnecessary last-minute changes.
2. Always create a project schedule. Many days before the start of the project.
3. Use a methodology that is agile and not reluctant to changes.
   
   

Ques.56. What is CaaS?
Ans. CaaS stands for Communication as a Service. CaaS is useful for application deployment. It is a type of cloud service where the service provider allows the clients to manage and release containerized applications.

Ques.57. What are the risk and issues?
Ans. Both the terms might look similar but risk is a future event. It is the negative impact that the company might go through. This is due to decisions taken in the present.
Whereas, the issues are errors that come up in the present and can be fixed.

Ques.58. What is a misuse case?
Ans. A misuse case is an activity performed by a user that causes a system failure. It is derived from the opposite of the use case. It may be a malicious activity that misguides the system function flow.
The misuse cases are created to improve the quality of the system. The cases that could not be involved in the use cases are included in this. Thus risks can be identified to customers specifically.
