Phase 1

Fundamentals

Days 1 – 7
Day 1 What is Power BI? 2 hrs

Power BI is Microsoft's end-to-end business analytics platform. It lets you import data from any source, model it, create stunning visualisations, and share insights across your organisation — all without writing a single line of code.

  • The Power BI ecosystem overview
  • Business Intelligence vs Data Science vs Analytics
  • When and why companies adopt Power BI
  • Your first look at the Power BI Desktop interface
💡 Pro Tip: Bookmark the official Power BI documentation — it's the single best free reference you'll have.
Day 2 Desktop vs Service vs Mobile 2 hrs

Understanding the three pillars of Power BI is critical. Desktop is your authoring workbench. Service is the cloud-based sharing and collaboration hub. Mobile delivers dashboards to any screen.

  • Power BI Desktop — the developer's primary tool
  • Power BI Service — publish, share, govern
  • Power BI Mobile — consume on the go
  • How the three products work together in a real workflow
💡 Pro Tip: Create a free Power BI Service account right now — you'll need it by Week 4.
Day 3 Installing Power BI Desktop 1.5 hrs

A clean install and proper configuration saves you hours of troubleshooting later. Walk through the entire setup and familiarise yourself with the ribbon, canvas, and panes.

  • Download Power BI Desktop from the Microsoft Store
  • System requirements and compatibility check
  • First launch — the interface tour
  • Configuring default settings and privacy options
💡 Pro Tip: Always install from the Microsoft Store — it auto-updates for you.
Day 4 Importing Data (Excel & CSV) 3 hrs

Data is the fuel. Learn to pull in structured datasets from the two most common file formats and understand how Power Query previews and transforms data before it hits your model.

  • Get Data → Excel Workbook — step by step
  • Get Data → Text/CSV workflow
  • Power Query Editor — first look
  • Checking column types and null values
💡 Pro Tip: Always preview your data in Power Query before loading — changing column types later is painful.
Day 5 Basic Visuals 3 hrs

Visuals are how you speak to stakeholders. Master the three most-used chart types and understand when each one is the right choice for your data story.

  • Table visual — displaying raw data cleanly
  • Bar chart — horizontal comparisons
  • Column chart — vertical category comparison
  • Dragging fields, formatting axes and titles
💡 Pro Tip: Less is more. One clear visual beats five cluttered ones every time.
Day 6 Building Your First Dashboard 3 hrs

Combine everything from Days 1–5 into a single cohesive dashboard. This is your first real deliverable and the foundation for every project that follows.

  • Arranging visuals on the canvas
  • Adding a title and colour theme
  • Basic slicer for interactivity
  • Saving and reviewing your work
💡 Pro Tip: Use the "Align" tools in the Format tab — aligned visuals instantly look 10× more professional.
Day 7 Week 1 Review & Mini-Project 3 hrs

Consolidation day. Build a complete mini-project end-to-end using a sample sales dataset — this proves you can work independently before moving to the trickier Week 2 topics.

  • Download a sample sales dataset
  • Import, clean, and build 3 visuals
  • Add a slicer and a title page
  • Save and do a self-review checklist
💡 Pro Tip: Save this file — you'll revisit it in Week 2 to add relationships and DAX.

🏗️ Hands-On Projects

What You'll Build

Every project is a real deliverable you'll add to your portfolio. No toy examples — only work that demonstrates genuine capability.

Week 1

Sales Overview Dashboard

Your first end-to-end report. Import a sales dataset, build 3 visuals, add a slicer, and create a clean one-page dashboard. This is the foundation every future project builds upon.

Tables Bar Charts Slicers Formatting
Outcome: A polished single-page dashboard ready for a basic portfolio.
Week 2

Sales Analytics Report

A multi-table project with a proper star schema. You'll create 8 DAX measures, build Year-over-Year comparisons, and produce a 4-page interactive report. This is where you cross the line from "user" to "developer."

Star Schema DAX Measures Time Intelligence Multi-Page
Outcome: A complex, interview-worthy report demonstrating modelling and DAX skills.
Week 3

Executive KPI Dashboard

The pinnacle of visual design. Build a C-suite-worthy dashboard with drill-throughs, custom tooltips, performance optimisation, and mobile-responsive layouts. This one turns heads.

Drill-Through Tooltips Performance UX Design
Outcome: A showcase-quality dashboard that demonstrates advanced Power BI mastery.
Week 4

Full Business Intelligence Solution

The capstone project. Plan, build, publish, and share a complete BI solution — from raw data to a live, shared report in Power BI Service with proper permissions and scheduled refresh. This is your graduating project.

End-to-End Publishing RLS Scheduled Refresh

Top Interview Questions

01
What's the difference between Measures and Calculated Columns?

Measures are context-aware aggregations computed on-the-fly. Calculated columns are row-level and stored physically in the table. Default to measures for performance.

02
Explain CALCULATE in your own words.

CALCULATE evaluates a measure in a modified filter context. It's the most versatile DAX function — nearly every advanced measure uses it.

03
Why do you prefer a Star Schema?

Star schemas are fast to query, simple to maintain, and natively supported by Power BI's query engine. Snowflake adds joins that slow things down.

04
How do you handle slow-performing reports?

Use Performance Analyser to identify bottlenecks. Reduce calculated columns, remove unused data, and consider switching from DirectQuery to Import mode.

05
What is Row-Level Security?

RLS restricts which rows a user can see in a report, based on their identity. It's critical for multi-user dashboards where data access must be controlled.
