9. Module 9: Domain Knowledge & Case Studies

Industry-specific domain knowledge helps Business Analysts understand the context, regulatory constraints, and user expectations of various systems. This chapter provides three practical case studies to illustrate the BA role across e-commerce, healthcare, and banking domains.

This chunk describes the importance of domain knowledge for Business Analysts (BAs). It emphasizes that BAs need to understand not just what they are working on, but the environment and regulations surrounding it. Understanding specific industries such as e-commerce, healthcare, and banking helps BAs effectively analyze business needs and develop appropriate solutions. The chapter aims to showcase real-world examples to illustrate the BAs' roles in these industries.

Think of a doctor who specializes in cardiology. To effectively treat their patients, they must understand the heart, how it functions, and the various diseases that can affect it. Similarly, BAs in different industries need their own 'specializations' to address the specific needs and challenges of their projects.

📌 Project Objective Design and deliver a shopping cart feature for an online retail platform, enabling users to add, update, and purchase items.

✅ Key Business Requirements ● Users can add multiple products to the cart ● Cart contents are saved across sessions ● Discounts and promo codes can be applied ● Cart updates dynamically with stock availability ● Checkout process integrates with payment gateway

👥 Stakeholders ● Product Owner ● Marketing Team ● Customers ● Logistics & Inventory Team

📊 BA Activities ● Gather user stories (e.g., “As a shopper, I want to remove an item from my cart”) ● Create wireframes for cart UI ● Define business rules (e.g., max quantity per product, cart expiration) ● Document functional & non-functional requirements ● Conduct UAT for checkout and promo logic

🛠 Tools Used ● JIRA (User Stories) ● Figma (Wireframes) ● Confluence (BRD/FRD) ● SQL (Verify cart behavior in DB)

This chunk outlines the first case study, which focuses on developing a shopping cart feature for an e-commerce platform. It defines the project's objective, which is to create a user-friendly cart that allows customers to manage their purchases effectively. Key business requirements detail what functionalities the cart must support, such as saving cart contents, applying discounts, and integrating with payment gateways. It also highlights stakeholders such as the product owner, marketing team, and logistics teams who contribute to this project. The BA activities involve gathering user stories from potential users to inform the design and functionality of the cart, creating wireframes to visualize the cart interface, documenting essential business rules, and conducting user acceptance testing (UAT). Tools like JIRA and Figma are used throughout the project for managing user stories and designing UI wireframes.

Consider how online shopping works: a cart is like a shopping basket in a physical store. It allows you to collect items before you decide to check out and purchase. Just as a store needs to know how many items you can take home and whether discounts apply, an online store must manage these aspects digitally, which is what this case study illustrates.

📌 Project Objective Develop a system for patients to book, reschedule, or cancel appointments with doctors, with real-time availability and notifications.

✅ Key Business Requirements ● Patients can search doctors by specialty, location, availability ● Doctors can accept or reject appointment requests ● Automatic SMS/email reminders before appointments ● Admin dashboard for scheduling rules and blackout dates

👥 Stakeholders ● Patients ● Doctors & Medical Staff ● Admin/Operations Team ● Regulatory (HIPAA compliance)

📊 BA Activities ● Elicit functional and non-functional requirements ● Create activity diagrams for patient-doctor workflows ● Define data privacy requirements (e.g., storing patient data securely) ● Collaborate with QA on test cases for booking, notifications ● Assist in UAT with hospital staff

🛠 Tools Used ● Lucidchart (Process flows) ● Excel (Traceability Matrix) ● JIRA (Sprint planning and bug tracking) ● SQL (Validate appointment data and time slots)

This chunk describes the development of a healthcare appointment system, focusing on the ability of patients to manage their appointments with doctors. It outlines the project's objective, ensuring that patients can easily book, modify, or cancel appointments while receiving timely notifications. Key requirements ensure that patients can find doctors based on specialty and real-time availability, and the system supports reminders for appointments. The stakeholders include patients, medical staff, and administrators, highlighting the complexity and regulations involved, such as HIPAA compliance. BA activities include defining technical requirements, creating workflow diagrams to illustrate interactions between patients and doctors, ensuring data privacy, and conducting testing with staff to verify system effectiveness. Tools like Lucidchart and JIRA are essential for creating visual representations and managing project tasks.

Imagine the way a receptionist manages appointments in a healthcare facility. They need to track who is coming in, when they are available, and ensure that patients receive reminders about their upcoming visits. This digital system does the same job but works more efficiently, connecting patients and doctors through a user-friendly application.

📌 Project Objective Build a digital loan application portal to streamline the process of applying, verifying, and disbursing personal loans.

✅ Key Business Requirements ● Users can apply for a loan with ID and income documents ● System auto-calculates eligibility based on rules ● Risk engine flags high-risk applications ● Integration with credit bureaus (e.g., CIBIL) ● Application tracking via dashboard

👥 Stakeholders ● Customers ● Credit & Risk Team ● Operations (Verification Team) ● Legal & Compliance ● Loan Officers

📊 BA Activities ● Gather BRD and map user personas (Salaried vs Self-Employed) ● Write user stories and define system integrations (APIs with credit bureaus) ● Coordinate test scenarios for fraud checks and KYC compliance ● Prepare data mapping for reports and dashboards ● Assist in training call center on system usage

🛠 Tools Used ● Draw.io (Data Flow Diagrams) ● Confluence (BRD, API documentation) ● JIRA (Requirements and test logging) ● MS Excel (Eligibility criteria modeling)

In this chunk, we examine the banking sector's loan application process. The objective is to develop a digital platform that simplifies how users apply for personal loans and how these applications are processed. Key requirements include the ability for users to apply with necessary documentation, automatic assessment of eligibility, and tracking of their application status. Stakeholders involved range from customers to loan officers, underscoring the various roles in the process. Business Analysts engage in activities like gathering business requirement documents, identifying user types (like different employment statuses), defining integration with credit reporting systems, and ensuring compliance with regulations like anti-money laundering checks. Tools such as Draw.io and JIRA are utilized for creating process maps and tracking project progress.

Consider how applying for a loan would feel if done entirely on paper: tedious, requiring you to visit offices, fill out forms, and wait for long periods. Now imagine a streamlined digital process. It's like ordering a coffee through a coffee shop's app rather than waiting in line — faster, more efficient, and more convenient, just as this digital loan application system aims to achieve.

“Business Analysts succeed not just by knowing how to write requirements — but by understanding the business context in which they operate.”

The final chunk summarizes critical takeaways for Business Analysts (BAs) from the case studies. It highlights specific challenges and skills required in different domains: e-commerce relies on understanding dynamic pricing and real-time stock validation, the healthcare sector focuses on compliance and managing complex scheduling, and banking requires risk analysis and knowledge of regulatory constraints. The take-home message is that the success of BAs goes beyond just writing requirements; it includes understanding the broader business context and needing to adapt skills to various industries.

Think of a BAs' role like a tour guide. To provide the best experience, a guide must know not only the paths to take but also the history of the locations, potential challenges, and diverse interests of the travelers. Similarly, BAs need a rich understanding of their industry to lead successful projects.
