Small Groups Registration

Small Groups Registration

The Small Groups Registration is a mobile app that optimizes the application and follow-up process of farmer groups accross India, Kenya, Tanzania, and Uganda that are part of the TIST program (The International Small Group and Tree Planting Program). By centralizing this process into a single mobile tool, the app reduces field costs and improves data accuracy.

Created to mitigate climate change while improving the lives of people in need, TIST promotes the goal of conservating agricultural management while enabling participants to earn income through verified carbon credits that can be turned into cash.


Their application process depended on fragmented data sources, Pendragon forms, handwritten notes and manually transcribed spreadsheets, that were compiled and managed by "Cluster servants".

Their application process depended on fragmented data sources, Pendragon forms, handwritten notes and manually transcribed spreadsheets, that were compiled and managed by "Cluster servants".

This lack of centralization has made monitoring costly and inefficient, often requiring long verification processes to gather evidence for groups that might drop off and long waiting periods to receive cash incentives, followed by the risk of TIST being perceived as an untrustworthy organization.

First steps in the field
First steps in the field

When the project was handed to us, it had already been worked by another team for almost three months, but it was approached purely from a graphic design perspective.


After our team reviewed the prototype, we quickly realized it lacked intuitiveness, logical flow and clear feedback mechanisms, but we had a major issue… the delivery date was less than two weeks away.

Old Design

We already had a design system used on a previous project, TIST's learning platform, so we retrieved the look & feel for the new app, ensuring visual consistency across all our TIST's products.


Our main task was to rethink the user experience from the ground up, creating a flow that would guide Cluster Servants through the registration, while keeping the interface aligned with TIST’s visual identity and functional requirements.

With the help of my team lead and the information provided by the company's instructional team, we first began mapping the user journey and reorganizing the registration process into clear, sequential sections:

01

Group details

Group name, geolocation and group photo.

To support the navigation through the app, we added:

1

Bottom navigation bar

Added also as an inherited feature from the learning app, it will provide quick access to registered groups, settings and accesibility features.

2

Confirmation modals

To reassure users their information was successfully saved and to administrate apps permissions.

3

Visual examples

To provide additional information to identify species, and give instructions that need specifal requirements, ensuring consistent submissions across regions.

The first sprout

Once we had finished mapping the user journey, my new duty was to bring our ideas into high-fidelity interfaces.


With the previously stablished design system, I designed base screens, modals, illustrations and gathered images for the whole flow. With the guidance of my team lead, I reiterated several screens until we were satisfied with the final layout, as we weren't convinced they fitted the proposal's standard, until we were satisfied with the final layout.

We validated this mockups with the instructional design lead in charge of this project, but apart from changes in the instructions we didn't get further feedback.

Once we had green light over the mockups, I rushed to have the protoype as soon as possible so we would be able to test if it runned smoothly from end to end for the stakeholder's testing.

Presentating the proposal
Presentating the proposal

As I was assigned to present the prototype for our stakeholders, I practiced my speech with my UX lead, so we could give the flow a final check and time the whole presentation.

The participants of the meeting were the Instructional Design project lead, the Development lead, one of the co-founders of Yeltic (the company I work for) and a Cambridge representative (TIST main associate).


We addressed all the changes in the registration flow, the logic behind them and the added features compared to the actual process.

After the prototype passed internal validation, we were ready to show it to the project's stakeholders.

Iteration and feedback

During stakeholder review, we received highly positive feedback. The interactive prototype was particularly valuable, as it clearly demonstrated the intended navigation and flow of the registration process.

One key insight came from the Cambridge representative:


"The app should be viewed not as a short-term form, but as a long-term record, where Cluster Servants continuously update the group’s progress over time. The trees and stumps section correspond to the registry process as this step takes time and sources that are often wasted due to groups droping off the process."

This insight led to a significant structure change, dividing the registration into two main steps:

  • Expression of Interest (initial data collection)

  • Registry (baseline grove information and ongoing tree data updates)

All the worked we had done, specifically corresponded to the Expression of interest.

Growing together

The project was ultimately approved by TIST, it's under the first steps of development and it will be tested by Cluster servants for a second round of feedback and polishing.


Although I'm not part of the final testing process, I'm really grateful for the opportunity to participate in a project that has so much social impact as it keeps growing.

Presenting it directly to stakeholders and showcasing the flow through a functional prototype, actually opened a door for an upcoming 2026 project where it's planned to overcome the second step of the registration process… which by the way, was assigned to my team and I'm currently working on the next steps with the guidance of my UX team lead.

After the positive acceptance of the project and my now relieved agenda, I was able to look back and realise how much we had achieved under 7 days.

Working on a real-life tool with a positive impact on people's life, made me understand how empathy and functionality go hand in hand. Even under pressure (…a lot of it), I learned to:

  • Prioritize usability features and simplify complex processes.

  • Gained practical experience in building a coherent experience across multiple connected products within the same ecosystem.

  • Understood the value of designing scalable products for long-term user interaction, not just one-time tasks, as user's needs evolve as data grows.

  • Strengthened my confidence presenting UX decisions and receiving feedback from senior stakeholders and clients.

Seeing how our redesign was so well received, made this project's experience very valuable to me. Eventhough I'm not always so aware of it, this little achievements make me realise my own growth.
