Who Is a Business Analyst?

Business analyst – commonly known as BA – is one of the job titles in the data science family. Business analysts analyze business operations and give recommendations on how to improve them. In other words, their role is optimizing processes, often including implementing new technology.

What Does a Business Analyst Do?

The shortest and most exact description of what business analysts do is that they act as a bridge between business needs and technical solutions.

Good, but how do they do that?

An Overview of What a Business Analyst Actually Does

From the high-level point of view, a business analyst’s job description consists of these five responsibilities.

An Overview of What a Business Analyst Actually Does

1. Requirement Gathering: Working with stakeholders to understand and formalize their business needs. Simply put, business analysts need to understand how a certain process looks, what the people involved do, and how they do it.

2. Data Analysis: They analyze the collected data and look for patterns and areas for improvement.

3. Process Improvement: They identify improvements needed to the process, which may or may not require a software solution.

4. Solution Design: If a new software solution or improvements to the existing ones are needed, business analysts work with the development team on the solution design. It is to ensure that it meets business requirements.

5. Change Management: Business analysts make sure the transition from the old to the new process or solution is done smoothly.

Roles and Responsibilities of a Business Analyst

To get into even more specifics about the business analyst’s job, we first need to know what the business analysis process looks like.

We can visualize it this way.

Roles and responsibilities to understand what does a business analyst do

The business analyst’s responsibilities are directly related to the stages of the process. By knowing the importance of each stage and techniques used, the exact role and responsibilities of a business analyst will start to unravel in front of your eyes.

1. Define Business Areas and Scope

In this initial stage, BAs identify the areas of business that will be affected by the project. Its purpose is to establish the scope and the focus of the project so that it’s managed effectively and all the relevant sides of the business are involved.

Roles and responsibilities to understand what does a business analyst do

There are several reasons why this stage is important.

1. Focusing the Efforts: With clearly defined objectives and the scope of the project, it’s easier to concentrate on relevant business areas and avoid misallocation of resources.

2. Identifying Stakeholders: Connected with the point above, this stage is also used to identify stakeholders. That way, everybody impacted by the project can be involved.

3. Risk Management: The project's potential risks can be identified in this stage, enabling their management.

4. Setting Clear Objectives: The precise objectives of the project have to be set against which the success or failure of the project will be measured.

5. Resources Optimization: With the clear objectives and scope of the project, it’s easier to utilize resources efficiently, i.e., time, staff, cost, etc.

6. Scope Creep Management: This stage prevents scope creep, i.e., the uncontrollable increase in the project’s scope.

Business analysts can use these techniques to achieve these objectives.

Roles and responsibilities to understand what does a business analyst do

1. SWOT Analysis: The SWOT analysis is used to identify strengths, weaknesses, opportunities, and threats of the project.

2. Use Case Diagrams: A use case diagram shows how the systems and external entities interact. Visualizing it gives you a clearer picture of the project scope.

3. Scope Modeling: This technique involves creating visual models (e.g., context diagrams) that represent the project scope, including systems, processes, and stakeholders.

4. Business Process Mapping: To easily understand business processes and identify needed improvements, BAs can create visualizations of existing processes.

5. Stakeholder Analysis and Mapping: BAs have to identify and thoroughly understand stakeholders, their roles, and their impact on the project. That way, it’ll be easier to meet their business needs.

6. Feasibility Study: Its purpose is to establish the project's viability, ensuring that the assumptions and expectations are realistic, considering available resources.

7. Work Breakdown Structure (WBS): WBS is used as a tool to break down the project into smaller parts that the project team will work on.

8. Requirements Workshops: These workshops gather stakeholders and collaboratively understand different stakeholder groups' specific, sometimes even contradictory, requirements.

2. Requirement Gathering

In the next stage of business analysis, also called requirement elicitation, BAs work with stakeholders to understand and document their business requirements and current business processes. This aims to ensure the project team that will design and implement solutions understands the business requirements.

There are several reasons this stage is important.

Roles and responsibilities to understand what does a business analyst do

1. Clear Guidelines: The gathered requirements will serve as guidelines for the project team, making sure the implemented solution meets the stakeholders’ business needs.

2. Risk Management: When the requirements are clearly defined and well documented, it’s easier to identify potential risks, thus making it possible to manage them in this early stage.

3. Optimizing Resources: Well-understood requirements make it possible to allocate needed resources. In other words, forming a project team of an adequate size and expertise, along with outlining realistic timelines for the milestones. Also, there will be fewer surprises along the way and, ideally, no need to constantly go back to this stage and revisit the business needs.

There are many techniques available to BAs for this stage. They depend on the type of project and the size of the company. Usually, several of these techniques are used simultaneously.

Roles and responsibilities to understand what does a business analyst do

1. Interviews: The requirements can be gathered in one-on-one or group interviews.

2. Questionnaires: Interviews are sometimes very time-consuming. Questionnaires can be used instead of or to complement them. Having stakeholders fill in the questionnaires gives the collected information a structured form.

3. Documentation Analysis: Business analysts also need to analyze the existing documentation, such as company policies, procedures, manuals, and system documentation. The purpose is to understand the current processes, which will serve as a basis for their improvement.

4. Observation: BAs can also directly observe how the stakeholders work to understand workflows better.

5. Workshops: One of the tools BAs have at their disposal is workshops. In other words, organizing meetings where stakeholders can define requirements through collaboration.

3. Analysis

The third crucial role of business analysts is the analysis of the gathered requirements. It aims to structure collected information, understand, refine, and prioritize the requirements. In this stage, business analysts extract insights from data that will be used in informing the stages of the project.

Here’s why this stage is important.

Roles and responsibilities to understand what does a business analyst do

1. Ensuring Clarity: It ensures the requirements are clearly defined and unambiguous.

2. Identifying Gaps: This stage is used to recognize if there are any missing requirements or pieces of information that could significantly impact the project.

3. Prioritization: Business analysts have to determine each requirement's priority, ensuring that the most critical requirements are first met.

4. Risk Management: This stage also helps identify and manage risks connected to the requirements.

5. Feasibility Check: During analysis, BA checks the feasibility of the requirements. In other words, whether they are realistic and achievable.

6. Stakeholder Alignment: This phase ensures that stakeholders understand and agree to all the requirements and proposed solutions.

The techniques used in this stage are shown below.

Roles and responsibilities to understand what does a business analyst do

1. SWOT Analysis: Business analysts once again use SWOT analysis to understand the factors that could impact the project.

2. MOST Analysis: They also use the MOST analysis (Mission, Objective, Strategies, Tactics) to make sure that the project is in line with the company’s business strategy.

3. Use Case Analysis: With the help of the stakeholders, BAs develop use cases that explore whether the solution will be able to meet all the business requirements.

4. User Stories and Epics: Business analysts create user stories and epics to define the users’ needs concisely.

5. Functional Requirement Analysis: This type of analysis means analyzing the requirements regarding the proposed solution functionality, i.e., what it should do.

6. Non-Functional Requirement Analysis: This technique means analyzing the requirements in relation to what the solution should be, i.e., its accessibility, data integrity, robustness, stability, etc.

7. Gap Analysis: Business analysts have to identify the gaps between the capabilities of current and future systems using gap analysis.

8. Impact Analysis: The project's changes have to be analyzed, and their impact on the company has to be assessed. This is impact analysis.

9. Cost-Benefit Analysis: BAs have to confront the expected benefits of the project and the cost to achieve them in a cost-benefit analysis.

10. Data Flow Diagrams: The data flow has to be visualized to understand how the data moves through the company. In other words, it has to be clear where and how data is stored, processed, and used. Data flow diagrams are used for that.

11. Requirement Prioritization Matrix: Business analysts use a matrix to visualize the requirements’ importance compared with the cost of implementing them.

4. Documentation

Once all the above is done, business analysts must document requirements in detail. The documentation needs to be accurate and comprehensive but also understandable, as it will be presented to all the stakeholders and project team members.

This stage is vital for the following reasons.

What does a business analyst do

1. Clear Communication: All the requirements have to be communicated comprehensively and clearly to the stakeholders for validation and then further on to the development team.

In this stage, business analysts use the following techniques.

What does a business analyst do

1. Use Case Documentation: Using the scenarios, BAs describe how the end-users interact with the system to understand the system’s functional requirements.

2. User Stories: With the help of user stories, BAs once again create concise descriptions of the system’s features from the perspective of various end-users.

3. Business Requirement Document (BRD): The BRD is a document with detailed information on the business problems, proposed solutions, involved stakeholders, functional and non-functional requirements, etc.

4. Functional Specification Document: The FSD gives detailed descriptions of the system’s features in terms of data handling, user interface, etc. In other words, it describes what the system is supposed to do.

5. Data Dictionaries: Business analysts create data dictionaries, which are repositories of data where each data element is defined. It involves the meaning, origin, usage, format, and relationship with other data elements.

6. Visual Modeling and Diagrams: The diagrams such as data flow, entity-relationship (ER), and state-transition diagrams are used to visualize data flows, structure, and the behavior of the system.

7. Traceability Matrix: Business analysts use a traceability matrix to connect the users’ requirements with the test cases.

8. Requirement Management Tools: Business analysts have at their disposal tools such as Jira, Confluence, or Microsoft Azure DevOps. They are used to document, manage, and track requirements.

9. Process Workflows: They are used to visually represent all the steps required for a particular task from start to finish.

5. Validating Requirements

This is the next stage in business analysis. It serves as validation that the requirements gathered and documented in the previous stages are in line with the expectations of the stakeholders.

Validating requirements is important for the following reasons.

What does a business analyst do

1. Ensuring Accuracy: It checks the accuracy of everything documented so far.

2. Risk Management: As with any stage so far, this one also helps in identifying and managing potential risks early enough in the project.

3. Avoiding Rework: It minimizes the possibility of going back to the initial stages of the project and re-checking the business needs once the implementation starts.
