Making final adjustments and preparing deliverables
Large-scale management and organization systems play a crucial role in industries that handle complex operations and data management. In energy data analysis specifically, professionals often encounter inefficient workflows and unintuitive interfaces that make their tasks more challenging to navigate.
Our main stakeholder, who works at Calpine Energy Solution, uses a traditional Revenue Management (RM) system that allows data analysts to review customer records, maintain databases, and execute various analysis reports. However, the current system is outdated, difficult to navigate, and often freezes when handling large data sets.
Energy data analysts working with customer records struggle with complex, poorly documented systems that require extensive learning time, causing them to repeatedly miss analysis deadlines and experience growing anxiety about falling behind on multiple client deliverables.
Given the increasing volume of data and the growing reliance on technology for decision-making, improving the user experience of these systems became a necessity for our stakeholder. Our team was tasked with redesigning the interface to create a more intuitive, efficient, and error-free workflow for their data analysts.
We conducted interviews with two key stakeholders. Our goal was to understand the current software used for large-scale data management and the challenges that stakeholders face in their day-to-day operations.
Daily Activities: Analyzes customer records, ensures accurate accounts setup, performs correlation analysis on billing and utility data, and follows up with utilities regarding billing inquiries for CCA customers.
Tools Used: Outlook, SQMD, CAISO Metering, Calpine Website Tool, Excel, SQL, Microsoft Teams, Revenue Manager (RM), SDGE & Utility Websites, Visual Cron
Pain Points: Outdated RM app that freezes when working with large datasets; confusing tab placement that switches positions; unintuitive toolbar functions; cannot access records when SCE fails to send updates overnight or when archive processes are paused
Daily Activities: Manages procurement activities, negotiates contracts and rates for parts and labor, develops cost-saving strategies, and creates/manages purchase orders worth millions of dollars.
Tools Used: Outlook, Microsoft Excel for data analysis, PowerBI for visualizing trends, Microsoft Teams, and in-house ERP system for supply chain management
Pain Points: Challenges managing large amounts of data; difficulty transferring between different systems; time-consuming report generation in PowerBI and ERP; unintuitive user interfaces; lack of visual feedback for supplier compliance
Our semi-structured protocol included:
Our primary stakeholder is a Data Analyst for Calpine Energy Solution. Their responsibilities include:
Throughout their day, they use multiple software applications, but the two main ones are:
Junior Data Analyst
Jack is a junior data analyst with a pre-med background who feels overwhelmed by setbacks and stuggles with the company's new interface, cuasing stress and delays.
Senior Data Analyst
Jaquline, a senior data analyst, with 20+ years of experience (15 in energy), excels in complex tasks but struggles with system delays that disrupt deadlines. These system delays are often due to accidental errors made by analysts due to the unintuitive workflow of the in-house software.
We conducted a competitive audit of similar data analysis tools to identify best practices and potential improvements for our redesign. We compared three major products in the energy data analysis space:
| Features | Tableau | EnergyCap | DNV |
|---|---|---|---|
| Web Based | Yes | Yes | Yes |
| Learning Curve | Highest | Lowest | Moderate |
| Data Visualization | Excellent | Standard | Limited |
| Real-Time Monitoring | Limited | Yes | Yes |
| Dashboard Customization | High | Moderate | Read Only |
| Large Datasets | Struggles | Handles Well | Handles Well |
| Collaboration | Yes | Yes (not live) | No |
These insights guided our design decisions, helping us focus on creating an interface that combines the best aspects of these tools while addressing the specific needs of energy data analysts.
Based on our research and competitive analysis, we developed UX flows to map the user journey through the redesigned interface. We focused on the most common tasks performed by data analysts:
This flow addresses the main pain points identified in our research:
We developed two distinct approaches for our low-fidelity wireframes:
The first approach featured a simple, tab-based environment that focused on:
The second approach took a more experimental direction with a node-based canvas that offered:
We also explored a hybrid approach that combined elements from both designs, which later influenced our final direction.
For our low-fidelity prototypes, we used:
We conducted user tests with our primary stakeholders to evaluate both prototypes. Participants were asked to complete the following tasks:
The testing revealed a strong preference for Prototype 2 (node-based interface) with some elements from Prototype 1:
Users emphasized that Prototype 2 provided a more customizable workspace that would help them organize information according to their specific needs, making their workflow more efficient.
Based on this feedback, we decided to focus on the node-based design while incorporating some elements from the tab-based approach, particularly the customer information layout that users found intuitive.
Our high-fidelity prototype focused on refining the node-based workspace concept while addressing the feedback received during user testing. We maintained a clean, intuitive layout while adding more customization options and clearer visual hierarchy.
Using Figma as our primary design tool, we created a comprehensive high-fidelity prototype with interactive elements. This allowed us to simulate the actual user experience and test more detailed interactions before implementation.
Based on additional feedback from peers, TAs, and stakeholders, we made several key improvements to our high-fidelity prototype:
These refinements addressed the feedback we received and improved the overall usability and aesthetics of the interface.
Our redesigned Revenue Manager addresses the key pain points identified in our research while incorporating best practices from competitive products and feedback from user testing.
The final design creates a more efficient workflow by:
Users can now complete their analysis tasks more efficiently, with fewer errors, and with a reduced learning curve for new team members.
This project demonstrated the importance of balancing innovation with user needs when redesigning complex interfaces. By taking a node-based approach to data organization, we were able to create a more intuitive, flexible workspace that adapted to users' workflows rather than forcing them into rigid structures.
The feedback from stakeholders was overwhelmingly positive, with particular appreciation for the balance between customization capabilities and structured organization. The redesigned interface not only addresses the immediate pain points but also creates a foundation for future enhancements as the system evolves.
This case study highlights how thoughtful UX/UI design can transform complex, technical tools into intuitive systems that enhance productivity and reduce frustration, ultimately creating a better experience for those who rely on these tools daily.
This project was a collaborative effort by a team of dedicated designers who brought diverse perspectives and skills to the challenge.
