Connected Supply Chain Platform

A digital tracking platform to process and record the diamond journey from mine to export and beyond.


The connected platform was designed to process the data that is received from the GemFair digital tracking mobile app. The connected platform records the diamond journey from mine to export in order to maintain the traceability and record the fair value.

Lack of transparency and traceability has been a historical risk and challenge for the diamond supply chain, especially in the ASM (Artisanal Small-scale Mined) sector.






How might we create a trustworthy data processing platform to support data integrity?

How might we provide supporting data to assist buyers to make a better decision?


How might we help users to build a sense of confidence in using the app with or without an inconsistent internet connection?

How might we integrate with the De Beers IP (the price book) without duplicating the data while also protecting data from unauthorized parties?


I led the design and project management for the connected supply chain platform. I led efforts to evolve the features and address user pain‐points and needs related to collaborating with internal tools and improving the experience for users with unstable internet connections.

User Insights & Ideation

I conducted user interviews to uncover insights and translate concepts into features that address customer behaviours and motivations.

Experience Strategy & Vision

I created frameworks and prototypes to share the vision and led the product strategy to look beyond the current scope and be forward-thinking to align with business strategy. 

Planning & Scope Definition

I defined the product with the Lead Engineer. With the user's needs and balancing business goals in mind, I worked with the Lead Engineer to prioritise and negotiate features for each sprint and launch.

Design Execution & Validation

I executed journeys, wireframes, prototypes and design specs. I worked closely with end-users to ensure the product addresses user needs and provides a pleasant and satisfactory user experience.


User insights

When I reviewed the various existing data tables in the app, I questioned if they served the right information and met the users' needs.

I started with understanding the purposes and functions of each table and mapping out the connections between them. With the business requirements of 1) expanding the functionality of the app, and 2) using the opportunity to improve the current framework, I conducted user interview to help me answer the following questions:

- What is the user trying to do the data from the table?

- What are the events that happened before and after the user interacted with the table?

- Does the current table help the user take action with confidence?

- What don't you need to see on the table?

Feedback from the users:

The tables are very similar to each other and it is hard to get the information immediately.

I only want to see the most recent data on the "At the mine" tab.

There are some missing steps in the purchase flow that are unable to fulfil my needs.

I rarely use the transaction history page because it doesn't serve meaningful information to me.

I am unable to filter and look for a particular item.

The app provides the wrong information which stops me from processing the data. 

To protect the De Beers IP (Intelligent Property) I have to do pricing separately. I wish there was an easier and efficient way for me to use the platform. 

The insights gathered from the users helped me to redefine the user stories and translate concepts into features that addressed user behaviours and motivations. 


Designing data tables

A good data tables should provide clarity on the information presented and help users take action with confidence. 

Here is the comparison with the previous design:

As the product involved and grew into a more complex platform, I have made several improvements for the global table design through the platform. The changes I made have improved the useability significantly according to feedback from users.

The connected Supply Chain Platform receives data from the digital tracking app; then, the users continue to process the data through the diamond supply chain. The connected platform aims to provide data transparency and traceability. The key activities in the platform include the diamond purchase flow, export flow and stock management.

To comply with my non-disclosure agreement, I have omitted and obfuscated confidential information. I have limited information and images shared here. The information in this case study is my own and does not necessarily reflect the views of GemFair or The De Beers Group.


Diamond purchase flow

The purchase page is used by buyers to process diamond purchases. The purchase flow is designed with a strict rule to assist the Responsible Sourcing Assurance Programme.  

The design direction I focused on here was to create an intuitive and informative user flow to assist diamond buyers in making decisions with confidence. The approaches I took included: simplifying the steps, providing information accordingly and thoughtfully preventing errors

Diamond export flow

The export page allows users to select and choose the diamonds they desire to export. The export process includes several steps that some users found to be complex and frustrating.


The design direction I focused on here was to divide the process into logical and manageable steps, giving users options to save their progress during the export process, while assuring data integrity. The approaches I took included: optimizing the diamond selection methods to align with the diamond stocking categories, preventing unintentional changes and human error and ensuring data is recorded exactly as intended

The Connected Supply Chain Platform is the world's first digital traceability system for the diamond supply chain in the Artisanal Small-scale Mined (ASM) sector. It is very challenging to develop something that hasn't existed before. We are learning and improving the system as we go. Here are the key successes:  

Sourced over 2,100 carats of traceable diamonds

Helped over 100 artisanal mines bring their products to into the international market

Recorded and processed over 500 transactions.
