First of all, the BA should get a document signed by the relevant party that after a specific date, no changes to the requirements will be accepted.
After that, they will identify the changes, evaluate their impact on the project, assess the resources available for implementing them, and check whether the proposed measures affect functional documents, coding or testing in a project.
The tools they must be well-versed to use, in this regard include Microsoft Office, Rational tools and ERP systems.
3. What are the documents used by a BA in a project?
The list is pretty long, but major documents are Functional Specification document, Technical Specification document, Business requirement document, Use case diagram and Requirement Traceability Matrix, among others.

- Activity diagram (the flow from one activity to another)
- Data flow diagram (the flow of data into and out of the system)
- Class diagram (a fundamental building block for detailed programming)
- Entity-relationship diagram (a data modelling technique)
- Sequence diagram (shows how objects operate)
- Collaboration diagram (communication between the objects)
8. What is the Kano Analysis?
Kano Analysis is a powerful technique used to identify the end-user requirements for a new product. It deals with the needs of the end consumers of the product. The main attributes studied in this technique include threshold attributes (what a customer expects), performance attributes (what adds extra enjoyment to using the product) and excitement attributes (what a customer does not know about but is excited to discover).

CATWOE makes the users answer questions like, "Who has ownership of the business?" and "What environmental impact can be seen because of the new changes?"
12. What is the purpose of the Requirement Traceability Matrix (RTM)?
RTM is a type of technique that records all the requirements stated by a client. The purpose of RTM is to ensure that all of those requirements are met.
13. How do you perform requirement gathering?
In requirement gathering, each step involves specific tasks to perform, principles to follow and documents to produce. The steps include collecting background information, identifying stakeholders, discovering business objectives, evaluating options, defining scope, creating a business analyst delivery plan, defining project requirements, supporting implementation through SDLC and evaluating value added by project.
14. What are the elicitation techniques in Business Analysis?
The elicitation is a requirement gathering practice involving several techniques such as:
- Document analysis
- Interface analysis
- Reverse engineering
- Conducting interviews, focus groups and surveys
15. What is the System Requirements Specification (SRS), and what are its key elements?
SRS is a set of documents that outline the features of a system or software application. It provides a high-level idea of the system and its functionality. The critical elements of SRS include the scope of work, functional requirements, non-functional requirements, dependencies, data model, assumptions, constraints and acceptance criteria.
16. What is a use case, and how do you design one?
A use case is an integral part of the software modelling technique. It is a diagrammatic representation of a system that describes how someone can use the system to accomplish a goal.
The steps involved in designing a use case include identifying the users of a system and creating a profile for each category of them; defining the essential goals associated with each group, creating the use cases for each goal based on a user template, and structuring, and reviewing and validating the use cases.
