Domain
Where are we?
The industry, its segments, the players and the regulators that shape it.
You walk away with: A one-page domain map
The nine layers, in order
Each layer answers one question. You do not move on until you can answer it about the industry you are learning.
Business
How does it make money?
The business model, stakeholders, and the KPIs leadership watches every week.
You walk away with: Value chain + KPI list
Process
How does the work flow?
End-to-end processes, the steps, the roles and the business rules at each step.
You walk away with: End-to-end process flow
System
Which applications run it?
The core systems in the landscape and what each one is responsible for.
You walk away with: System landscape diagram
Data
What information matters?
Master and transactional data, key fields, and how records change over their life.
You walk away with: Key entities & fields
Integration
How do systems talk?
Interfaces, message standards, APIs, files and events between systems and partners.
You walk away with: Interface catalogue
Transaction
Follow one, end to end.
A single real transaction traced step by step across every process, system and interface.
You walk away with: Transaction walkthrough
Testing
How do we prove it works?
Test types, the high-risk scenarios, test data needs and what to validate at each layer.
You walk away with: Test scenario checklist
Real-world scenario
What happens on a live project?
A production-style case: what went wrong, how it was traced, and the test that would have caught it.
You walk away with: Case study & lessons
Why this order works for QA, BA and delivery roles
Most domain "training" is a glossary. You memorise that GMROI is gross margin return on inventory investment, or that an 837 is a claim file, and none of it sticks, because you never saw where it sat in the business.
The nine layers force the opposite sequence. You learn what the industry is and how it makes money before anyone shows you a screen. By the time you reach the System layer, you already know what each application is for, so the landscape diagram explains itself. By the Testing layer you are not guessing at risk — you know which transactions carry the money and which failures a business would actually notice.
What that changes on a project
- Requirements get read against the business, not just against the screen.
- Test scenarios cover the flows that carry revenue and compliance risk first.
- Defect triage gets faster because you can trace a transaction across systems.
- Conversations with business stakeholders stop needing a translator.
The framework applied, domain by domain
The same nine questions, answered for each industry BDC teaches.
Retail
From the buyer's plan to the shelf, the checkout and the return — how stores and online retail really run.
Healthcare — Provider
Hospitals, clinics, diagnostics and home care — how care is delivered, documented, coded, billed and paid.
Insurance
Turning risk into a product — how policies are priced, sold, serviced and claimed.
Banking
Deposits, loans and payments — the systems that move money safely every second.
Finance
The finance function and capital markets — how companies record, close and report every rupee.
Government
Digital public services — identity, benefits, taxes and procurement at population scale.
Logistics
First mile to last mile — how shipments are stored, moved, tracked and delivered.
Common questions
What is the BDC nine-layer learning framework?
A fixed order for learning any business domain: Domain, Business, Process, System, Data, Integration, Transaction, Testing, Real-world scenario. Every Business Domain Connect track answers the same nine questions in the same sequence, so what you learn in one industry transfers to the next.
Why learn a domain in this order?
Because software teams usually start at the System layer — they are shown screens and told what to build or test. Starting at Domain and Business means you understand what the industry does and how it makes money before you look at a single application, which is what lets you spot the requirement nobody wrote down.
How long does one track take?
Ten sessions per domain: one per layer, plus a certification assessment. Sessions release weekly on the YouTube channel, and enrolled learners get the materials for every layer as the track builds.
