A good business analyst should responsibly implement several key methods for a perfect workflow within the organisation. There are many key responsibilities of a business analyst like:
| Aspect | Data Analyst | Business Analyst |
| Focus | Analysing and interpreting data | Identifying business needs and solutions |
| Primary Tasks | Data collection, cleaning, and visualisation | Requirement gathering, process improvement |
| Tools Used | SQL, Excel, Python, R, data visualisation tools | JIRA, Microsoft Visio, requirement management tools |
| Output | Reports, dashboards, and data-driven insights | Business requirements documents, process models |
| Objective | Provide insights from data | Improve business processes and solutions |
| Interaction | Mostly with data and technical teams | With stakeholders, business units, and technical teams |
| Skillset | Strong analytical and statistical skills | Strong communication and problem-solving skills |
Agile strategy is mainly used for managing projects and also in creating new software that takes input from the end-users and interprets information in more manageable parts. Waterfall has a strict process followed by several steps before moving on to the next stage. Comparing both of them, agile is more flexible.
A process flowchart can be used to easily indicate tasks and all the processes that are required in a project. It is generally an illustration made using a diagram. Using it, one can easily enhance productivity, convey projects to other members, refine resources and overall development of the project.
A requirement is a wanted trait or operation that a product or procedure needs to fulfil, usually expressed in broad terms. Conversely, a specification is a specific outline of how a requirement will be executed or realised, encompassing technical specifics, norms, and limitations.
To complete a particular task, a use case is used. It works by outlining the process by the participants, assigning tasks, and all the detailed actions performed by them. Its overall aim is to optimise task management.
Here’s what you need to do:
In Business Analysis, a wireframe serves as a diagram or sketch that depicts the framework and organisation of a website or application. It highlights the fundamental framework and arrangement, concentrating on how it functions and the experience it offers to users while excluding design aspects such as hues or illustrations.
To record and monitor different systems, Unified Modeling Language (UML) is used. It involves monitoring all logs and communications to store better records to keep up with the organisation’s requirements.
A Gap Analysis is a method employed in Business Analysis to evaluate the disparities between the present condition of a process or system and the envisioned future condition. It encompasses three primary steps:
The ‘AS-IS process describes the present condition of a business procedure, illustrating the existing methods. The ‘TO-BE’ process shows the envisioned future condition following enhancements or modifications have been made.
Kanban is a graphical system designed to apply agile and lean methodologies in the creation of software and the management of projects. It highlights the importance of gradual enhancements to procedures and aims to increase productivity while reducing unnecessary waste. Kanban employs visual displays, cards, and constraints on ongoing tasks to assist teams in organising and prioritising their activities efficiently.
A Pugh matrix is used to compare and evaluate multiple results, which are based on criteria set by the user. It is also called decision matrix or grid analysis. This is often used in the development of any product, making business analysis statistics, and prioritising tasks for better task management.
It’s a methodical instrument designed to assist in assessing different options by considering various factors and supports the process of making educated choices based on numerical data instead of gut feelings.
A backlog works as a sorted collection of tasks or features that should be done in any project. It consists of a compilation of problems outlining the tasks your team plans to undertake on a project. It serves as an efficient place for organising, keeping track of, and handling various types of issues that are in progress.
Here you can use IS NULL and IS NOT NULL operators to null values in SQL. IS NULL operator looks for the null values while IS NOT NULL identifies non-null values present in the database.
| Aspect | Online Transaction Processing | Online Analytical Processing |
| Purpose | Manage day-to-day transactions | Analyse and query data for decision-making |
| Type of Queries | Simple, frequent | Complex, ad-hoc |
| Data Usage | Current, up-to-date | Historical, summarised |
| Database Design | Normalised | Denormalised |
| Data Model | Entity-Relationship Model | Star or Snowflake Schema |
| Performance | High transaction throughput, low latency | Complex queries, potentially slower |
| Concurrency | Many users performing transactions | Few users performing analytical queries |
| Examples | Retail sales, banking transactions | Business reporting, data mining |
In SQL, a window function is employed to execute computations over a group of rows connected to the current row. It is generally used for determining priority among tasks, monitoring progress by several calculations, and necessary averages according to dynamic data allocation.
A Business Process Model and Notation (BPMN) helps to recognise standards in business processes. It helps to maintain continuous progress by different graphical representations of data, examination techniques and quantitative analysis in any business project.
A Project Manager is responsible for planning, implementing, and managing the overall workflow of a project. All the remaining tasks and objectives to be done by any individual are managed by the project manager. They guarantee that projects are finished punctually, within financial constraints, and adhere to quality criteria.
Prioritisation of requirements is one of the most important and initial parts of any business project. Taking account of those elements which contribute to the main project, resource allocation, sorting tasks based on importance and time-saving pipeline workflow should be done. Some of the methods for prioritising resources are MoSCoW and the Kano model.
| Aspect | Risk Mitigation | Risk Avoidance |
| Definition | Reducing the impact or likelihood of a risk occurrence | Eliminating the risk by avoiding the activity |
| Focus | Minimising the effects of a risk if it occurs | Preventing the risk from happening |
| Approach | Addressing the risk through proactive measures | Steering clear of activities with potential risks |
| Example | Installing fire extinguishers to reduce fire risk | Choosing not to build a factory in a flood-prone area |
| Goal | Manage risks to an acceptable level | Eliminate risks for certain activities |
A business rule is a precise, implementable declaration that outlines limitations, necessities, or standards inside a company. It determines the procedures for conducting business activities or the management of data. For instance, a business rule for a bank could be “To open a new account, customers are required to present authentic identification.”
Here, you can say your communication skills are strong in both verbal and written forms. Verbal communication helps in gaining immediate feedback and understanding from anyone. On the other hand, written communication helps format documentation and maintain clarity in any written form.
You encountered a challenging stakeholder who was hesitant to embrace change. To handle this, you established a connection, paid attention to their worries, and highlighted the advantages. You persuaded them of the project’s worth by encouraging transparent speech and understanding, eventually securing their trust in completing the project.
Suppose you had to manage two projects that had deadlines that coincided. You can sort tasks by assessing their significance and immediacy. By engaging with stakeholders to discuss and adjust deadlines, you can distribute time based on the importance of the projects. This approach guaranteed that both projects were finished punctually without sacrificing their quality.
Here, you can provide an in-depth examination of the advantages and possible drawbacks of the project and emphasise how the change would improve the project results. Additionally, you can propose different options to tackle any worries, which lead to their approval.
You can follow these tasks:
To develop a project schedule, start by pinpointing essential activities and significant achievements. Predict how long each will take and arrange them in a sensible order. Allocate necessary resources, take into account what needs to happen before others can start, and include backup plans to guarantee a timeline that is both feasible and attainable.
In executing risk management for your project, you pinpoint possible dangers, evaluate their probability and severity, create strategies to reduce their effects and oversee and manage these risks from start to finish.
In Business Analysis, the importance of data modelling cannot be overstated. It plays a key role in comprehending and recording the needs of data, creating effective databases, and guaranteeing the quality of data. Moreover, it supports clear communication among all parties involved, which in turn results in more informed choices and positive results from projects.
To conduct this, several methods include analysing different elements and aspects of the project. For example, tech-stack, scheduling and cost, legal formalities, and economic value of the project in future, etc. features should be taken into account.
To effectively manage scope creep, you must ensure that the project stays on track and meets its target. Here are some tasks you can perform
You can mention the following tools:
To overcome any outcome issues in a project, or to find any potential threats, a graphical method is used which is called a fishbone diagram. This method uses problem statements, brainstorming methods, categories for its branches, and asking why any problem occurs to form the diagram. It is mainly used to find the root cause of the problem. As per the name, the diagram looks like a fishbone.
To extract data from various origin points, an ETL (Extract, Transform, Load) method is used. It also converts data into a uniform structure that helps it to merge within a designated database or data repository. Many computational methods are used to alter data, examine, integrate and form reports.
Here you can mention the usage of common techniques between Informatica or Talend ETL tools. Both are used in moving data from one source to its target but perform different methods. Both have slight differences in repository, components, transformations, design area and overall interface.
You can mention both the tool’s skillset or you can mention anyone you have used. An overview of both tools is mentioned below.
Jira: Used to prepare burndown charts, sprint reports, tracking tasks, etc., for the advancement of the project. Agile reporting is also supported in Jira and has a limited number of users on the free version. It is mainly supported by agile software development teams.
Trello: Trello comes with a far better and ready-to-use interface, with a lot of templates to initialise with. It supports individual work management, synchronous team activities, private team collaboration, tracking and automation.
Your reply should be customised to mirror your real-life experiences. Here’s a sample reply:
“My involvement with CRM software has been extensive, particularly with Salesforce. I’ve utilised it for handling customer information, monitoring communications, and evaluating sales outcomes. Additionally, I’m well-acquainted with HubSpot and its functionalities.”
| Aspect | BRD | SRS | FRS |
| Focus | Business needs and high-level requirements | Detailed software requirements | Detailed functional requirements |
| Audience | Business stakeholders | Developers, testers, project managers | Developers, testers, designers |
| Contents | Business objectives, scope, high-level requirements | Detailed functional and non-functional requirements | Detailed functional requirements, use cases, scenarios |
| Granularity | High-level | Detailed | Detailed |
| Scope | Overall project scope | Specific software system or product | Specific features or functions |
| Purpose | Defines what needs to be achieved | Describes how the software will function | Details of how each function will behave |
| Changes | Changes are expected as business needs evolve | Changes are managed through a formal change control process | Changes are managed through a formal change control process |
| Examples | Project overview, stakeholder requirements | Use cases, software requirements, data requirements | Functional requirements, interface requirements, data requirements |
A Business Requirements Document (BRD) details the business challenge or chance and explains the business necessities and goals. It generally encloses the project boundaries, managing the requirements from stakeholders, functional needs, and limitations in a project.
Performing a financial evaluation for a system improvement project. You can say about examining the expenses associated with the upgrade, like software fees and the process of putting it in place and comparing them to the advantages, such as enhanced productivity and decreased upkeep expenses.
Identify potential dangers by reviewing previous projects, seeking advice from involved parties, and employing methods to identify risks. Furthermore, we can reduce these dangers by creating several backup strategies, assigning new tasks, and, most importantly, keeping an eye on risks at every stage of the project.
Business Analysis primarily deals with functions and processes, while Business Analytics centres on data.
Business Analysis identifies the needs of a business and devices solutions to address these issues. It uses various tools and techniques such as SWOT, PESTLE, CATWOE, MOST, FIVE WHY, etc.
On the other hand, Business Analytics is used to gain insights into a business’s operations and managing data. It culminates in the creation of reports. There are several categories like descriptive analytics, prescriptive analytics, decisive analytics, and predictive analytics.
The user Acceptance Testing (UAT) method uses the development of test strategies and scenarios on business needs, engaging users in the testing process, recording their input, and guaranteeing that problems are fixed. UAT is in sync and needs detailed records and consistent interaction with stakeholders.
You can mention some practical performance assessments by examining the technical, operational, and financial elements. Weighing elements like expenses, duration, assets, hazards, and possible advantages are used to ascertain if they are feasible and in line with the company’s objectives. You can also mention SWOT analysis and how you conduct feedback from stakeholders.
Here’s a table differentiating between risk mitigation and risk avoidance:
| Aspect | Risk Mitigation | Risk Avoidance |
| Definition | Reducing the impact or likelihood of a risk | Eliminating the risk by not engaging in the activity |
| Approach | Implementing measures to manage risk | Choosing not to undertake the activity that generates the risk |
| Examples | Installing security systems, creating backup plans | Not launching a high-risk product, avoiding specific markets |
| Impact on Project | Risk is still present but managed | Risk is eliminated, but potential opportunities may be lost |
| Cost | Often involves additional resources or measures | This can result in missed opportunities or benefits |
| Implementation | Requires continuous monitoring and adjustment | One-time decision, with no need for ongoing management |
The Spiral Model is excellent in complex., high-profile projects because of its sequential approach and emphasis on evaluating risks. Whereas, the Waterfall model is more appropriate for straightforward, simple projects where requirements are fixed. Waterfall is a linear sequential approach where the client cannot give feedback at the middle stage of the project.
Hence, the spiral model works better for projects that need continuous changes and client approval for each stage because it is an iterative approach.
