Backstory
In the high-stakes world of manufacturing, every second of machine downtime translates to lost productivity, increased costs, missed deadlines, and wasted materials. Traditional quality control methods rely heavily on manual oversight and intuition, making it challenging to prevent issues before they escalate.
Elementary, a leader in AI-powered quality inspection stations, set out to transform how manufacturers approach quality control by introducing a platform that leverages predictive analytics and data storytelling. This platform not only aggregates vast amounts of production data but also turns it into actionable insights accessible across all organizational levels.
The Challenge
Manufacturers grapple with:
- Unplanned Downtime: Machine breakdowns halt production lines, causing significant financial losses.
- Inefficient Quality Control: Reliance on manual inspections and fragmented data makes it difficult to identify root causes of defects.
- Data Overload without Insight: Massive data lakes from various sensors and systems lack cohesion, preventing meaningful analysis.
- Collaboration Barriers: Disconnected teams struggle to communicate issues and solutions effectively.
Objective: Develop an analytics tool that provides real-time, actionable insights, enhances collaboration, and integrates seamlessly with existing manufacturing systems.
Design Process
To understand the needs and pain points of various stakeholders—quality engineers, operators, and executives—I conducted in-depth user interviews. I found users needed:
- Quick Issue Identification: The necessity for immediate recognition of problems to prevent escalation.
- Performance Benchmarking: A desire to compare shifts, machines, lines, and sites for a global performance view.
- Collaborative Root Cause Analysis: A need for tools that facilitate teamwork in identifying and resolving issues.
Additionally, secondary research involved scouring scientific journals and industry reports to identify ideal manufacturing processes, providing a foundation to create workflows that mirrored best practices.
At PackExpo, a major industry trade show, I developed a research guide to identify customer groups based on their data maturity levels:
- Visionaries seeking predictive solutions.
- Process Optimizers enhancing existing systems.
- Platform Seekers whose processes were failing and lacked a clear solution.
These insights, combined with user interviews, shaped user archetypes:
- Factory Operators: Require real-time, easy-to-understand alerts and intuitive interfaces to quickly address issues on the production floor.
- Quality Managers: Need tools for trend analysis, root cause identification, and collaboration to ensure consistent product quality.
- Data Scientists: Seek access to raw data, integration capabilities, and flexible analytics tools for advanced analysis and predictive modeling.
- Executives: Desire high-level insights, strategic reporting, and predictive analytics to make informed decisions and drive business efficiency.
Major Findings & Design Challenges
Communication and collaboration needed to occur across three main areas:
- Identification of Improvement Areas: Spotting high-value, low-effort opportunities for process and product quality enhancements.
- Performance Benchmarking: Comparing shifts, machines, lines, and sites to obtain a global performance perspective.
- Collaborative Root Cause Analysis: Addressing the struggle quality managers faced with fragmented data when identifying issue sources alongside manufacturing teams.
Collaborative Design Sprint
I facilitated a design sprint with a cross-functional team focused on developing solutions at every organizational level. User journeys were mapped out, interface ideas sketched, and prototypes developed that could adapt to identified factory worker needs.
Rapid Prototyping & Iteration
Interactive prototypes brought the vision to life:
- For Operators: Human-Machine Interfaces (HMIs) were designed to display clear, actionable insights and alerts. A "traffic light" system (green, yellow, red) indicated shift productivity and quality status at a glance, turning raw data into intuitive visual cues.
- For Quality Managers: A collaborative root cause analysis tool was developed, combining data points, timelines, and annotations. This enabled seamless communication between departments and facilitated effective issue resolution.
Collaboration with data scientists and developers ensured the platform integrated with existing systems—PLC, SCADA, MES, and ERPs—allowing seamless data collection and analysis. An executive dashboard offered top-level KPIs and deep-dive analytics, ensuring decision-makers had real-time visibility into the factory's health.
Validation & Testing
I used usability testing sessions on the factory floor to provided critical insights:
- Visual Preferences: Operators favored the "traffic light" alert system for quick comprehension.
- Time of Incident: Knowing when issues occurred was crucial for understanding context before and after incidents.
- Image Galleries: Users focused on image galleries, highlighting the importance of visual evidence in understanding issues.
- Collaboration Needs: The ability to share images facilitated collaborative root cause analysis among team members.
These insights led to iterative improvements:
- Enhanced Metrics Display: Failure rates were prominently displayed alongside previous rates for easy benchmarking, with color coding indicating trends.
- Top Defects Chart: An easy-to-scan list of defects, helped users quickly identify recurring issues.
- Share Image Feature: Implemented to facilitate collaboration and communication among team members.
- Dynamic Timelines: Provided to help quality managers pinpoint when issues occurred, enhancing the root cause analysis process
Rapid Development with High-Impact Daily Reporting
With users eager to replace their daily reports with Elementary's insights and challenged by limited resources, designs were simplified to expedite rollout:
- Focused KPIs: Failure rates, shift productivity using the "traffic light" system, total failed and inspected items were prominently displayed.
- Comparative Metrics: Previous failure rates were provided for quick benchmarking.
- Visual Aids: Bar charts for top defects facilitated quick understanding during shift meetings.
Low-Tech, High-Impact Solution
To meet immediate needs, I led creation of a streamlined reporting solution using Google Sheets integrated with the platform's data via App Script:
- Delivered Value Quickly: Met users' needs without waiting for full-scale implementation.
- Increased Trust: Demonstrated the system's capabilities, building user confidence and validating which KPIs were most needed.
- Unlocked New Metrics: Encouraged creative data presentation, leading to the development of previously non-existent metrics and insights.
This low-tech, high-impact approach not only provided immediate value but also validated the system's potential, strengthening user trust and engagement.
Outcomes
20% Increase in Shift Productivity: Identified and resolved a problematic process within the first week, significantly boosting efficiency.
Reduced Downtime: Proactive issue detection led to fewer production halts.
Enhanced Collaboration: Teams used shared insights and image-sharing features to make informed adjustments in real-time.
Adoption of Data-Driven Culture: Daily reports became integral to shift meetings, fostering reliance on actionable data and increasing brand equity for Elementary.
Strengthened Customer Relationships: The platform's immediate impact built trust and positioned Elementary as a critical partner in operational success.
