The Situation: 

E-commerce KPI Analysis is a collection of data related to its sales across multiple countries around the world. It encompasses various attributes, such as orders, sales, products, market, etc. Our goal is to transform their raw data into meaningful insights and recommendations for management. More specifically, we need to:

• Track KPIs (orders, sales, profit, quantity, profit margin)
• Compare regional and state-level performance
• Identify product effectiveness and customer behavior

The Data:

We’ve been given a collection of raw data (CSV files), which contains information about orders, quantity, sales, discount, products, categories, customers, segments, regions, markets and others, in a total of a single table, from the years 2020-23.

The Task:

We are tasked with using solely Microsoft Power BI to:

• Connect and transform/shape the data in Power BI’s back-end using Power Query
• Build a relational data model, linking the 2 fact and dimension tables
• Create calculated columns and measures with DAX
• Design a multi-page interactive dashboard to visualize the data in Power BI’s front-end

The Process:

1. Connecting and Shaping the Data

Firstly, we imported the data into the Power Query editor to transform and clean it. The process involved:

Removing Duplicates: Duplicate entries were removed from the dataset to ensure accurate analysis.

Data Type Conversion: Columns were converted to appropriate data types to ensure consistency. Dates were converted to Date type, numerical columns to Decimal or Whole Numbers, and text columns to Text.

Standardizing Date Formats: All date columns were formatted consistently to facilitate time-based analysis. This step was important for ensuring accurate time-series analysis in Power BI.

2. Building a Relational Data Model

Secondly, we modeled the data to create a snowflake schema. This process involved creating relationships between the dimension and fact tables, ensuring cardinalities were one-to-many relationships.

We enabled active or inactive relationships, created hierarchies for fields such as Geography (City-State-Country-Region) and finally hid the foreign keys from the report view to ease the data analysis and visualization steps and reduce errors.

3. Creating Calculated Columns and Measures

Next, we used Power BI’s front-end formula language, DAX, to analyze our relational data model and create several calculated columns (for filtering) and measures (for aggregation) that we could later reference and use when analyzing and visualizing the data.

We used calculated columns to categorize discount into defined groups. The list of calculated measures includes key information on sales, customers, orders, profit, quantity, and more.

4. Visualizing the Data

The final step of the project was creating a multi-page interactive dashboard, including a range of visuals and KPIs that could serve management and lead to informed decision-making. We used several visuals and tools to demonstrate and visualize the data across 3 report pages, including KPI cards, line, column and bar charts, matrices, donut charts, slicers, and maps. We ensured the report was fully interactive and simple to navigate, with icons used to enable filters, cancel filters, and guide users to each report page with ease. Features such as bookmarks and parameters were also used throughout the dashboard, further enhancing its usefulness and impact on management.

Overview Dashboard: The first report page provides a high-level view of overall performance. We used card visuals to present Key Performance Indicators such as overall sales, number of orders, quantity sold, profit and profit margin. We also included current and previous year performances of those matrices, providing insights into recent trends, a clustered bar chart to show sales and profit by product category, a line chart to display sales monthly trends, another line chart to show profit margin by discount segments, and a matrix to display the top 10 products with their overall sales, profit, profit margin profit margin by year.

Region View: The second report page is a regional overview page to further analyze the performance in a specific region. It consists of a clustered bar chart that shows sales by regions, a map chart to display sales distribution by regions, a line chart to visualize yearly sales of markets, and a matrix chart that displays top 10 countries with their sales, profit, profit margin and profit margin by year. This offers insight into sales distribution by region.

Customer View: The third and final report page provides deeper insight into customer behavior and value. It uses a donut chart to show total customers by segments, a column chart to show total customers by year, a clustered bar chart to display total sales and profit generated by segments, one more bar chart to show total customers by country, and a matrix to present customer’s purchase details, including city and country of order, sales, generated profit and profit margin.

The Situation: 

CRM is a collection of data related to its sales across multiple countries. It encompasses various attributes, such as total leads, conversion rate, total deal value, etc. Our goal is to transform their raw data into meaningful insights and recommendations for management. More specifically, we need to:

• Track KPIs (total leads, total deal value, leads closed, closed deal value, conversion rate, lost rate.)
• Provide insights into lead distribution across countries, industries, and organization sizes.
• Identify the health of the sales pipeline, forecast potential income over the next few months, and compare sales agent performance.

The Data:

We’ve been given a collection of raw data (CSV file), which contains information about organizations, industries, country, product, lead acquisition date, expected and closed date, and deal value, in a total of 1 table, from January 2024 to September 2024.

The Task:

We are tasked with using solely Microsoft Power BI to:

• Connect and transform/shape the data in Power BI’s back-end using Power Query
• Build a relational data model, linking the 5 fact and dimension tables
• Create calculated columns and measures with DAX
• Design a multi-page interactive dashboard to visualize the data in Power BI’s front-end

The Process:

1. Connecting and Shaping the Data

Firstly, we imported the data into the Power Query editor to transform and clean it. The process involved:

Removing Duplicates: Duplicate entries were removed from the dataset to ensure accurate analysis.

Handling Null or Missing Values: For some columns, missing values were replaced with defaults or averages. Null values in “key” columns were removed using filters.

Data Type Conversion: Columns were converted to appropriate data types to ensure consistency. Dates were converted to Date type, numerical columns to Decimal or Whole Numbers, and text columns to Text.

Column Splitting and Merging: Several columns were split to separate concatenated information or merged to create a unified name.

Standardizing Date Formats: All date columns were formatted consistently to facilitate time-based analysis. This step was important for ensuring accurate time-series analysis in Power BI.

Removing Unnecessary Columns: Irrelevant columns were removed to streamline the dataset. This helped focus the analysis on relevant information, reducing memory usage and improving performance.

2. Building a Relational Data Model

Secondly, we modeled the data to create a star schema. This process involved creating relationships between the dimension and fact tables, ensuring cardinalities were one-to-many relationships.

We enabled active or inactive relationships, created hierarchies for fields such as Date (Month-End of Month-Start of Month-Start of Week), and finally hid the foreign keys from the report view to ease the data analysis and visualization steps and reduce errors.

3. Creating Calculated Columns and Measures

Next, we used Power BI’s front-end formula language, DAX, to analyze our relational data model and create several calculated columns (for filtering) and measures (for aggregation) that we could later reference and use when analyzing and visualizing the data. The list of calculated measures includes avg. weeks to close, # of leads closed, lost deal value, sales person ranking and more.

4. Visualizing the Data

The final step of the project was creating a multi-page interactive dashboard, including a range of visuals and KPIs that could serve management and lead to informed decision-making. We used several visuals and tools to demonstrate and visualize the data across 2 report pages, including KPI cards, line and column charts, matrices, bar charts, and pie charts. We ensured the report was fully interactive, with slicers used to enable filters, and allow users to each report page with ease. Features such as parameters were also used throughout the dashboard, further enhancing its usefulness and impact on management.

Overview Dashboard: The first report page provides a high-level view of CRM’s overview. We used card visuals to present Key Performance Indicators such as Total Leads, Total Deal Value, # Leads Closed, Closed Deal Value, Conversion Rate and Lost Rate. We also included pie charts to show distribution of total leads, total deal value and conversion rate between products, a line chart to represent monthly lost rate and conversion rate, a line and clustered column chart to compare actual closed deal value and expected closed deal value by month, a clustered bar chart to show comparison between total deal value and closed deal value by sales agent, and a clustered bar chart to display conversion rate by country.

Performance by Month: The second report page is to further analyze the sales agent performance and monthly distribution of closed, expected and potential deal values. It consists of a line and clustered column chart that shows average weeks to close vs closed deal value by month, second line and clustered column chart to display average weeks closed before forecast vs closed deal value by month, a stacked column chart to show potential, closed and lost deal value from January to September 2024, a stacked column chart to display distribution of potential deal value by sales agent and product, and a matrix that visualizes performance of salespersons, countries, industries and organization size in closed leads, average weeks, and closed, potential and lost deal values, with addition of spark lines to display their monthly closed leads.
