Enhancing Reporting with Power BI: A Journey from Manual to Automated Insights

I’m thrilled to share a recent project I worked on that involved transforming a manually created PowerPoint report into an automated, dynamic Power BI dashboard. The journey has been both rewarding and insightful, and I’m excited to highlight the skills I applied and the impact of this solution.

The Business Challenge

Every week, our team would generate a retailer ticket trend report using PowerPoint and Excel. While the report provided useful insights, the manual process was time-intensive, prone to errors, and lacked interactivity. Stakeholders needed more detailed, real-time analytics to better track and manage retailer tickets by priority, team assignment, and backlog data.

The Solution

I reimagined this report using Microsoft Power BI, an intuitive business intelligence tool that enables interactive data visualization and automated reporting. The new Power BI dashboard addressed key pain points by:

1. Automating Data Integration: The dashboard pulls data directly from source systems, eliminating manual data entry and ensuring real-time updates.
2. Interactive Insights: Users can drill down into specific metrics such as ticket status, assigned teams, backlog trends, and retailer-level performance.
3. Improved Visuals and Accessibility: The Power BI dashboard provides a clearer representation of key metrics, making it easier for stakeholders to identify patterns and bottlenecks.

Key Features of the New Dashboard

• Dynamic Ticket Breakdown: Tickets are categorized by priority (e.g., P2, P3, P4), status (e.g., Resolved, On Hold, Work in Progress), and retailer.
• Team Performance Analysis: Visuals showcase ticket resolution by assigned teams, enabling targeted process improvements.
• Backlog Tracking: A dedicated section highlights tickets pending for over 30 days, facilitating better backlog management.
• Date-Range Analysis: Users can compare performance metrics across customizable date ranges.

Technical Implementation

Connecting ServiceNow with Power BI A critical aspect of this project was integrating Power BI with ServiceNow. I used REST APIs and Postman to establish and validate the connection between the source system and Power BI. Below is a code snapshot of how this connection was implemented:

import requests
import pandas as pd

# ServiceNow credentials and API endpoint
url = "https://<your-instance>.service-now.com/api/now/table/<table-name>"
username = "your_username"
password = "your_password"

# API request
response = requests.get(url, auth=(username, password), headers={"Accept": "application/json"})

if response.status_code == 200:
    data = response.json()
    df = pd.DataFrame(data['result'])
    print("Data fetched successfully!")
else:
    print(f"Failed to fetch data. Status code: {response.status_code}")

# Export data to CSV for Power BI integration
df.to_csv("servicenow_data.csv", index=False)        

Using Postman, I tested and validated the REST API endpoints to ensure data accuracy and troubleshoot any connectivity issues before integrating the script with Power BI. Automating this process ensures that the dashboard always reflects the most up-to-date information.

Business Impact

The shift to Power BI has had a significant impact:

• Time Savings: The manual report creation process, which took hours each week, is now fully automated.
• Improved Accuracy: Real-time data integration reduces the risk of manual errors.
• Enhanced Decision-Making: Interactive visuals and granular insights empower stakeholders to make informed decisions quickly.
• Scalability: The dashboard can be easily updated or expanded to accommodate new requirements.

Skills and Tools Used

• Power BI: Data modeling, visualization, DAX calculations, and dashboard design.
• REST API and Postman: Testing and automating data retrieval from ServiceNow.
• Data Analysis: Identifying trends, outliers, and actionable insights.
• Collaboration: Working with cross-functional teams to gather requirements and refine the dashboard.

Before vs. After

The attached screenshots demonstrate the transformation. The old PowerPoint report (Screenshot 1) required manual updates and lacked interactivity. The new Power BI dashboard (Screenshot 2&3) automates the process and offers dynamic, actionable insights.

Reflection

This project underscored the power of leveraging technology to enhance productivity and decision-making. It also reinforced the importance of aligning technical solutions with business needs. I’m proud to have contributed to a solution that adds tangible value to our organization.
