1. What is Business Analysis and Who is Business Analyst?

As per IIBA, Business Analysis is the practice of enabling change in an organizational

context, by defining needs and recommending solutions that deliver value to stakeholders.

One should not restrict the BA role to only being a link between Non-It and IT or only for

development projects. A BA is someone who is able to bring in improvements, changes

(technology, process, people etc.) in an efficient manner. So a BA could be part of the

marketing team who helps the marketing team in providing estimates/high level solutions for

a said project which is under the process of procurement. Or he could be someone involved

during the Requirement gathering/analysis once the project is initiated. Or he could be

someone who brings profit to the company by performing process improvement activities

ROIs at process level.

Last but not the least BAs could be domain specific as well.

2. What is the career path for a Business Analyst?

A Business Analyst in the IT field has many varied directions among which to choose a

career path. The most direct would lead to a Lead Business Analyst position and then Project

Manager whereby the incumbent manages projects through the entire lifecycle from inception

to post-implementation including the management of business analysts’ system analysts

quality assurance analysts and most likely development project managers or team leads. That

path would then lead to Program Management perhaps PMO management or Product

Manager and on to Directorship. In addition a good Business Analyst may find they are

heading toward a Customer Relationship Manager position whereby they become the primary

IT interface to a given Business Unit (BU). This role most often leads to a position within the

BU as a Manager of Applications or a Process Management role. Process Management opens

many jobs including process re-engineering quality program development and large scale or

enterprise process management programs such as ITIL or Six Sigma initiatives. These roleswill continue to proliferate as companies realize the benefits of having a SME in process and

quality. And still many Business Analysts find their understanding of business process

entirely portable into purely system related positions in the business side that are only

peripherally related to IT. These of course may lead to quantitative roles manager roles or

operational roles such as supply chain logistics et cetera.Of central importance to a successful

Business Analyst is the interest in speaking to people. Face to face verbal communication is

paramount to support other tools such as surveys and diagrams. Incumbents must be

interested in understanding not only the pieces that comprise a system but the people that

comprise it and the realities that embrace the system. Briefly the Business Analyst mustunderstand and not judge the what should be and the what is.

3. How would you transform business requirements to functional requirements?

While preparing Business requirements documents you mention why you need to built a

system, i.e. problem statement. What you need to do while creating functional requirements

is you have to specify is, solution of the problem. Specify thoroughly business problem and

explain solution for the same.

Business requirement documents do not necessarily contain solution part, functional

requirement may contain it how end user wants the system to perform. Don’t forget to add

non-functional requirements same doc.

Following is the instance of Business Requirement, Functional Requirement and Non-

Functional Requirement.

Business Requirement Functional requirement Non-Functional Requirement

Sales order is made against

customers purchase order.

Sales order is given for

approval to upper authority

Sales order shall be made with

reference from Purchase order

and it should be approved

from upper authority.

Sales order should be in proper

format (Specify format) and six

copies of sales order should be

printed from printer in 1 minute.

4. How do you resolve issues?

I would rather focus on issues and the facts related. Origin of issue, severity of the issue,

implications and possible solutions to solve the issue. Try not to focus on the person who

brought up the issue.

Another important part is how to avoid similar issues in future.

5. What analysis and modeling techniques do you use to translate business

objectives into system requirements?

-initiation diagrams including business use cases, activity diagrams,

workflow diagrams, flowcharts

business diagrams

activity diagrams or other techniques

-relationship diagrams from the use cases or other high level diagrams

g the other relevant types of

UML diagrams, detailed design entity-relationship diagrams, and decomposed dataflow

diagrams

cycle, and understand which diagrams are derived from others

intelligently on the topic and review diagrams that have been normalized or decomposed



knowledge/

6. Mention some of the tools commonly used by business analyst?

There might be various tools that you as a business analyst would be using depending upon

the work environment.

The primary tools are:

MS-Office (Especially Word)

MS-Visio (for visualizing the concepts, creating diagrams)

But a lot of bigger organizations have been using Rational Software. Rational software

licensing is expensive so you might not find it being used everywhere.

Rational Requisite Pro (for Requirement Management)

Rational ClearCase/ClearQuest (For change management)

I have also found that some places like using MS-SharePoint, telelogic DOORS and other

tools for document collaboration. I would say, keep a working knowledge of MS SharePoint,



4/20

at least.

Sometimes you might end up being a BA com QA. As such, it is nice to have a working

knowledge of creating Test cases, using Load Runner, QTP etc.

Except for these tools if you have knowledge of RDBMS, Oracle, SQL, different operating

systems, some OOP, it is always a plus.



knowledge/

7. Explain equivalence class?

Equivalence class a mathematical concept is a subset of given set induced by an equivalence

relation on that given set. (If the given set is empty then the equivalence relation is empty and

there are no equivalence classes; otherwise the equivalence relation and its concomitant

equivalence classes are all non-empty.) Elements of an equivalence class are said to be

equivalent under the equivalence relation to all the other elements of the same equivalence

class. For each equivalence relation there is a collection of equivalence classes. Any two

different equivalence classes are disjoint and the union over all of the equivalence classes is

the given set. Equivalence classes and their corresponding equivalence relation are defined inset theory a vital foundation for mathematics and those fields that use mathematics. More

details can be found in a study of equivalence relation.



knowledge/

8. What are the problems solved by business analysis?

As a BA the most critical part is in gathering requirements (we should understand them very

well from a Business User /stake holder point of view!!!)

Reason: There might be a chance for the whole project to go in the wrong path due to wrong

understanding of the Business users/ Stake holders’ needs and the gathered requirements

created for the work following that step… i.e. going from A to C instead of going from A to

B.

Notes: (Business Users: are the individuals who work in organizations in different

departments like Logistics accounting finance Inventory) in the company who wanted thesoftware in Place for them to work on to help the Customers.

Stake Holders: Someone who is related to the Project? 2 types of People are involved:

Direct Stake holders: business end users customers developers tech team.

Indirect stake holders: management etc.The Project Manager responsibility (usually) identifies the stakeholders determine their needs

and expectations and more important must manage and take their help for the project success.

(You should Understand them well to provide them with right service for the right success of

the project)...

SME’s: are the Subject Matter Experts who know about that project and have in-depth

knowledge about that software application used and that particular business domain

knowledge like Finance (terms and permutations etc.) Accounting (Business Planning Ledger

maintaining Forecasting) Mortgage (Local banking rules Knowledge about compliancy of

applications forms/ applications that needs the authorizations of the local Government bodies

or counties Underwriting conditions (How flexible the Loan lending organizations at the

individuals credit check or History)

So The SME’s help the Project Manager or BA to help them understand about the necessities

or needs of the Business Users or Stake holders like/interests- (How the Project help save

time for the transactions or? how much secure/security is needed the application wise or

profitable over long run) and SME’s explain How the Stakeholders or Business Users want

the application to be or appear to be for the Customers or Business Users).

9. What is the difference between data model and an entity relationship diagram?

A data model is a model which shows how data is stored and used for e.g. a normal database

It has 3 main parts 1)Structural part:- how data is structured 2)Integrity part:- Rules

governing structure3)Manipulation part:- operators used to select, update, query that data, e.g.

select, update, delete commands in SQL. To further add Data Modeling is when we add this

theory to Live instance. ENTERPRISE DATA MODEL (ENTERPRISE RELATIONSHIP

MODELING):- This can be called as an conceptual model or semantic model The sub parts

of an ERM are 1) Entity:- It is an object, e.g. employees, computer 2) Relationship:- It

captures how two or more entities are related to each other 3)Attributes:- Every entity has its

own sets of attributes (e.g. PAN no in India for each employee or SSN in US). To clarify the

points look at example: An employee is an entity belonging to entity sets (All employees)

which has a relationship with department, and attributes is emp code

10. Who uses the output produced by business analyst?

The output will be used by the Both IT and Non-It People, as IT people use this document as

key for the building of the application and Non - It people use those document where they

can see prototype of their application.



knowledge/

11. What is the educational qualification required for a business analyst?

There is no specific qualification for a business analyst. Well, if you are a management

graduate it is an added advantage since you have they have better communication skills. One

important thing a BA needs to have is domain knowledge or business knowledge. Unless

he/she understands the client's business process thoroughly they cannot draft the requirements

properly.



knowledge/

12.

Mention the components of UML?

UML uses many concepts from many sources. 1. For Structure: Actor, Attribute, Class,

Component, Interface, Object, Package. 2. For Behavior: Activity, Event, Message, Method,

Operation, State, use case. 3. For Relationships: Aggregation, Association, Composition,

Depends, Generalization (or Inheritance). 4. Other Concepts: Stereotype. It qualifies the

symbol it is attached to.

13. Mention some of the important points a business analyst must take care while

preparing business plan?

While Creating Business Document, Make sure you start from small problems. Don’t jump to

big problems right way. Keep the Business sponsors and IT folks in the loop. Make sure your

document clearly state Exceptions, Assumptions and Limitations. Sometime you need to keep

in mind the legal issues. Business document should be well written for usability and forfuture projects.

outstanding. Sometimes users are just looking for functionality in system and they are not

even able to say that what exactly will be their dream functionality which will be most

convenient to them. In that case BA should explore them and figure out the exactly demanded

requirements.



knowledge/

18. How is requirement analysis done by business analyst?

Requirement session is usually done through JAD session. Business Folks and Major

sponsors are always there along with some technical folks. Business analyst then goesthrough each requirement and asks for the feedback. If Business Sponsors and Technical

Folks think that all the requirements are according to the business and won’t be a barrier to

existing system. They get the official signoff on Business Requirement document. IT

manager and Business manager both do the sign off on that business requirement document.



knowledge/

19. Does the business analyst interact with clients directly? If so state the reason for

the same?

It depends on the project to project it is not always the same that we do interact with the

talk with for gathering business requirements. These people have regular daily works to do

and their time to spend in the gathering sometimes hard to schedule and for this reason

gathering business requirements is delay.

- resources management

- risk management

- Daily/weekly status report to project stack holders etc.

where as business analyst sometimes report to project manager or may report to business

manager.

Business Analyst deals with business users to gather requirements prepare RD, FD and

coordinate with development team for development and then do the testing involve with users

in testing get the sign off and move component to live environment.

I hope this clarify the roles of PM & BA.



25. Where would you document Functional and Non Functional Requirements (i.e.

deliverable)?

Functional Requirements are documented in the SRS document / Use Case Document. Non

Functional requirements are listed in the SRS document.



knowledge/

26. How do you identify the basic flow? What would you do if someone was

struggling to determine the basic flow for a use case?

Basic flow for use case can be identified from Business Requirement Documents or

Functional Requirement Documents as these use cases are prepared on the basis of these

requirement.



27. What is the relationship between use case and test case?

A use case is written from a "user" perspective describing the interaction of a piece of

software between the user and the software. These are written in common language typically

from the business or user point of view and in enough detail for the developer to create a

piece of software. Typically written in a MS Word type tool. Use cases capture the

functional requirements of the system. It describes the expected interaction the user will

experience, in detail. The audience is the business, for signoff, and technology fordevelopment.



11/20

A Test Case is written using the use cases for a source. It takes a use case to a deeper level so

that software testers can exercise every possible scenario that could occur, negative and

positive scenarios. One Use Case can turn into 10 test cases. 10 test cases make up a test

script. Typically Test Cases will be written in a testing tool like Test Director, but also can

be written in MS Word. The audience is QA testers.



knowledge/

28. What would you do if the client says that you and the other analysts cannot

directly talk to the users?

If this happens then explain the purpose of your talk (e.g. capture requirements) and why it’s

important to talk to users directly (e.g. the quality of requirements will be better if they come

directly from the users’ mouth). Explain them that it will be a high risk to the project if

analyst can't talk to the users directly. Client can give access to indirect (surrogate) users but

explain that the quality of requirements will be not good. Hopefully your client will agree by

now otherwise flag it as a higher risk in Business Requirement Document and highlight

during your meeting with your PM and Project Sponsors. Now, it’s your PM or project

sponsor ’s duty to provide you access to those direct users. If they can't than you are safe

anyways.



knowledge/

29. We are going to a client on Monday to help them with their requirements. We

have just received a business case from the client, and they have no tools in place.

What would we do the first week?

First week in this case is always advisable to do a due diligence of the amount of work,

expectations, existing process, time lines with the constraints surrounding. One of major

constraints in this case would include lack of tools.

Depending on the project timelines, complexity and volume of the project present your

recommendations for tools to be used and the estimated budget allocation required.

Document the comparison of productivity and flexibility with and without tools used.

This should help the project sponsors to take a call on going for tools

30. Version control and configuration management are terms used widely in the

business industry, write short notes about the terms.

By definition, version control is essentially a subset of configuration management. It is

usually concerned with the handling changes arising in previous documents as opposed to

configuration management which essentially handles the individual components.



knowledge/

31. Good documentation management systems are highly recommended in system

development; briefly describe the factors that contribute to a good

documentation management system.

32. State the different software methodologies.

The term software methodology, software development methodology and software process

mean almost the same thing in computer software or system development, i.e. the activities

carried out by computer system engineers or computer software engineers in an attempt to

procure particular computer software that servers a certain function or purpose. This includes

the framework adopted, structure, plan as well as the control of the resources engaged in the

software or system development process.

There are so many software methodologies and the choice as to which one to adopt is usually

dependant on so many other factors such as the purpose of the given software, the prevailing

conditions regarding the software development environment and the will of the company orthe client procuring or intending to use the final software as some clients even look into the

software or system engineers’ methodology to as one of the factors determining whether to

contract him or not.

Regarding the purpose of the software, let’s look at the following, example is a situation of a

safety critical system such as an aircraft navigation system and a business system, one would

find that in a business system, one can have its prototype done and users start using it as they

identify its weaknesses and tell the engineers to rectify whereas in an aircraft navigationsystem, no weakness would be allowed at all for it can cause huge loss of property and life

thus all the possible identifiable weaknesses are eliminated first before that system comes

into operation. Much stories and arguments apart, the following are the available softwaremethodologies:

SLDC- Software Development Life Cycle: also understood as System Development Life

Cycle which encompasses activities such as Analysis, Design, Implementation, Testing,

Inauguration and Maintenance in that order and then back to Analysis, note that it is a cycle

hence once we get to the last stage, i.e. the maintenance we still go back to the analysis stageand move along to the maintenance once more iteratively


14/20

The RUP – The Rational Unified Process: which when looked into intuitively is an

iterative software development process framework that was created by the Rational Software

Corporation in the US which is a division of the IBM (International Business Machine).

However, this process is usually not considered as a single prescriptive framework yet as an

adaptable process which can be tailored by the development team or organization selectively

in order to end up with their respective results depending on the needs prevailing either on the

client’s side, the industry standards or even the development constraints which involve time,

scope as well as the budget, Intuitively, this process has characteristics overlapping with

other development processes and methodology as will be seen when considering the other

methodologies below.

The iterative process: The basic idea behind this method is

to develop a system through repeated cycles (lterative) and insmaller portions at a time (incremental), allowing software

developers to take advantage of what was learned during

development of earlier parts or versions of the system.

Learning comes from both the development and use of the

system, where possible key steps in the process start with a

simple implementation of a subset of the software requirements

and iteratively enhance the evolving versions until the full system is implemented. At

each iteration, design modifications are made and new functional capabilities are added.

100. How would you influence people when you do not have decision making

authority?

Few business analysts have the final authority to make critical decisions on projects. That’swhy it’s so important for business analysts to polish their influencing skills.

The process used to influence people can be a formal, well thought out presentation, or it can

be an informal conversation. Either way, it never hurts to think through a standard

framework by which to structure your thoughts before attempting to influence someone. The

following is a concise 5-step framework that can be used for both formal and informal

communications that involve influencing another person or audience.

Define the What, Why, and Who

Prepare your case Deliver your message


19/20

Obtain a commitment

Agree to a specific action plan

These 5 steps provide a framework to structure and plan your communication to maximizeyour influence over a person or audience, but it’s the details of each step that will determ ine

how influential you will be.

1. Define the What, Why, and Who.

It’s important for you to have a well define and thoroughly understood objective. What is

your goal or objective? Why are you championing your particular position? Who do you

need to influence? Answering these questions will focus your case.

2. Prepare your case.

Notice that I didn’t say “prepare your argument”. Influencing is very different from coercion

or even selling. While there may be some selling involved, it should be a soft sell of the

benefits that you are espousing.

Consider how you can customize your case for the person or audience. What does the person

or audience value? What do you have to offer the person or audience? Do you have specific

technical knowledge? Do you have a strong network which could benefit the person or

audience?

For more formal communications, while you are preparing your case you should outline anumber of potential options for the action plan that might be used if you get the person or

audience to commit.

3. Deliver your message.

When delivering your message be direct in your thoughts and language. You want to come

across as respectful and open to the feedback of the audience, but do so without obscuring the

point of your message. Don’t hint at what you want, but also don’t demand.

Use powerful questions to engage your audience. Open-ended questions that lead the

audience to realize the advantages of your case work best.

4. Obtain a commitment.

Whenever possible, it is best to obtain a commitment immediately following the delivery of

the message while the benefits of your case are still fresh in the audience’s mind. Steer the

conversation to help your audience arrive at the stage where they are comfortable committing.

5. Agree to a specific action plan.

Even with a commitment, you are only truly successful once you’ve realized your

objective. That’s why agreeing to an action plan is so important.


20/20

Develop milestones for reaching the final objective

Identify resources and assign roles and responsibilities

Develop a method for tracking progress

To re-iterate, if you are planning a formal communication or presentation you will have a lot

more time to spend thinking through the details of this 5-step process. However, even for

brief communications within a short conference call, mentally thinking through these steps

for just a few second can help guide your conversation and increase your degree of influence

with your audience.
