Valuable Waste Management (VWM)

Enterprise

Internal

is an internal tool for tracking, processing, and shipping valuable manufacturing waste. It centralizes shipment creation, weight verification, discrepancy handling, and vendor coordination into a single workflow for production and dock teams.

My Role

Sole Product Designer

As the sole product designer, I led the end-to-end design of an internal waste management system used by production, dock, and accounting teams. I collaborated closely with MES and engineering teams to define workflow architecture, streamline operational processes, and design scalable interfaces for shipment creation, verification, and discrepancy handling.

Skills

The system is currently deployed and being monitored in production environments. Future work includes refining edge-case handling, monitoring operational usage patterns, and iterating on workflows based on ongoing feedback from production and dock teams.

Cross Functional Teams Collaboration

I collaborated closely with software and data engineering teams to define workflow architecture, simplify operational processes, and design scalable interfaces for real-time discrepancy tracking and review.

Problem

Valuable waste operations were spread across multiple tools and manual processes, making it difficult to maintain a consistent workflow across teams. Operators had to switch between systems, processes are different by teams, and on-boarding new operators required significant process knowledge.

From a business perspective, there was also limited standardization and visibility across the shipment lifecycle, creating an opportunity to unify the workflow into a single system.

Solution Vision

Design a centralized workflow that standardized how production and dock teams tracked valuable waste, with built-in safeguards for handling operational issues in real time.

Project Constraints

Multi-Role Complexity

Production, dock, and admin teams each required different workflows and permissions within the same system. The challenge was designing role-specific experiences while maintaining consistency across the platform.

iPad-Only Workflow

Stakeholders required the system to run exclusively on iPad, shaping the interface around touch interaction, portability, and limited screen space.

Discover

To better understand the process from user perspective, I have conducted:

Observations (Field Study)

  • Operators switched between multiple tools and physical locations to complete a single task

  • Label creation, weight verification, and shipment preparation were disconnected workflows

  • Issue resolution relied on Microsoft Teams communication between operators and supervisors

Interviews

  • Operators expressed frustration with the existing workflow

  • Supervisors had limited visibility into valuable waste progress

  • Repeated manual data entry created unnecessary effort

Task Analysis

  • A single task required movement across locations, tools, and manual approval processes.

  • System fragmentation created frequent interruptions and inconsistent execution.

Key Insights

Through discovery stage, I identified key insights.

⛓️‍💥

Daily operations were spread across disconnected tools

Production and dock teams switched between multiple systems and spreadsheets to complete a single workflow, creating missed steps and inconsistent data between teams.

🚨

Critical decisions occurred outside the primary workflow

Approvals and issue resolution were managed through Microsoft Teams instead of the primary system, causing critical decisions to happen outside the operational flow.

📋

Operational processes lacked standardization

Overflow bins, weight mismatches, and damaged labels were handled differently across teams, making the workflow inconsistent and difficult to audit.

Collaboration

VWM made possible through close collaboration across stakeholders, software and data engineering teams.

Feature Priority Alignment

I worked with MES team, alongside software and data engineers, through weekly syncs to prioritize scope and reconcile regional differences in quote detail requirements.

Collaborative Design Process

Stayed in close contact with software and data engineers using Teams throughout implementation, reviewing progress and refining interactions to keep the design consistent.

Design Principles

The key insights and collaborating with cross-functional teams led to core design principles that guided design decisions throughout the project.

1

Unify the Workflow

Replace fragmented tools and spreadsheets with a single system shared across production, dock, and finance teams.

2

Create Clear Operational Ownership

Design role-specific workflows so each team records and validates its own data before handing work downstream.

3

Reduce Training Overhead

Create workflows that are simple enough for teams across locations and technical backgrounds to learn quickly with minimal training.

4

Handle Exceptions Within the Workflow

Support edge cases like weight mismatches, overflowing bins, and approvals directly inside the system instead of relying on external tools.

User Roles

Waste Room Operator

Records daily waste activity and serves as the primary source of operational data entry.

Waste Room Supervisor

Oversees shipment creation and approves weight discrepancies before materials move downstream.

Dock Operator

Supports shipment preparation, weighing, and physical material handling.

Dock Supervisor

Manages receiving, weighing, conflict resolution, and vendor shipment workflows.

Design Process

Information Architecture

Organized around three core workflows: waste room, dock, and vendor shipping. Defining the structure early aligned engineering teams on system scope and role responsibilities before interface design began.

Draggable

Userflows

Mapped the counting workflow end-to-end to identify unnecessary steps and role handoffs. This helped simplify the process, reduce operational friction, and define the minimum number of screens required.

Wireframes

Created wireframes to validate the workflow structure and user journey before investing in high-fidelity UI. Partnered with cross-functional teams to confirm requirements, discuss technical feasibility, and iterate on key features early in the design process.

Prototype Testing

- Improved layout clarity and task sequencing reduced operator confusion. - Increased visibility across steps reduced unnecessary backtracking. - Structured information grouping improved readability in data-heavy workflows.

Time-on-Task Comparison

- Operators struggled to scan and prioritize large amounts of information within limited screen space. - The dual-column layout created confusion around task order during active workflows.

Stakeholder Feedback Loops

- Validated workflow completeness across production, dock, and approval stages. - Clarified ownership and handoffs between operational roles. - Ensured the system aligned with real-world operational constraints and processes.

Userflows

Before

Repeated loops and validation steps created unnecessary navigation throughout the workflow.

After

Reduced decision points and eliminated repeated loops, shortening the path from start to submission.

Wireframes

Before

Two separate pages, each with unused screen real estate and no visibility into previous inputs.

After

Consolidated into one continuous scroll, with all inputs visible and inline validation throughout.

Iteration Outcomes

Steps Reduced

11

steps

9

steps

2 steps reduced

Consolidated redundant interactions to reduce task completion effort without removing critical operational steps.

Removed Redundant Workflow

Eliminated intermediate confirmation and instruction screens that interrupted the shipment creation flow, allowing operators to move between actions with fewer interruptions.

Improved Data Validation for Accuracy

Introduced validation at key points in the workflow to catch errors during entry instead of after submission.

Final Solutions

Streamlined Shipment Creation

Operators can move from material selection to label generation and scanning in a single streamlined flow. Pre-set options reduce manual input and speed up task completion.

Strengthened Shipment Verification

Container information is automatically retrieved through label scanning or manual entry, while discrepancy checks help identify weight mismatches before shipment approval.

Improved Batch Processing

Batch scanning and editing reduced repetitive manual entry, allowing operators to process multiple waste containers more efficiently.

Reflections

Converting a disconnected workflow into one unified system was the primary challenge

The hardest part was not designing screens, but understanding a process distributed across physical locations, disconnected tools, and multiple operational teams. Defining the workflow clearly upfront made the rest of the system possible.

Working outside my usual domain improved cross-functional collaboration

VWM introduced operational and SCADA systems I had not previously worked with. Close collaboration with engineers and stakeholders became essential for validating workflows and making informed design decisions throughout the project.

Standardizing workflows improved day-to-day operations

Replacing fragmented processes with guided workflows reduced onboarding complexity and improved operational consistency across teams. After launch, operators and stakeholders reported smoother daily execution and fewer workflow interruptions.

Next Steps

The system is currently deployed and being monitored in production environments. Future work includes refining edge-case handling, monitoring operational usage patterns, and iterating on workflows based on ongoing feedback from production and dock teams.
