Designing a Simple and Effective Feedback Tool to Streamline Employee Reviews.


Problem - A legacy feedback system with many disabling processes, such as filling out and uploading spreadsheets, exporting files to inputs from other systems and performance monitoring not so assertive due to the richness of feedback details. An arduous and slow process.

I had the opportunity to be a part of an MVP development that required an enormous cross-team collaboration and development efforts, planned to be implemented in 60+ countries, starting in Germany and England for the testing period.


It's essential that Team Leaders have the ability to provide feedback and guidance to their team members as they take on any project, specially in large-scale projects. I was honored to be a part of the team that designed and developed this unified platform which serves over 35,000 employees across the globe.

I was of part of a multicultural team of 18 members distributed around the world, In a variety of seniorities spread across the following positions →

• Project Manager
• Product Manager
• Business Analyst
• QA Analyst
• Developers
• Researcher
• Agile Coach
Product Designer 
• UX Writer

These are the four initiatives that make up the Feedback system,
I was part of the second engagement:

Engagament 1 - IS

Supports the process to search and assign firm members to engagement opportunities.

Engagament 2 - EF

Enable team leaders to provide feedback to team members for every engagement.

Engagament 3 - DC

Enable collaborators to provide structure inputs about an evaluee's performance review cycle.

Engagament 4 - DE

Supports the performance review evaluation process, considering most of the roles involved.

Understanding business was my daily routine since the project has many integration flows between engagements

I put effort into learning the compliance terms, general flows (fig. 1), Stakeholder Map (fig. 2), and other systems' informations useful for our team work. 


We used a collaborative team board - an easy way to document, validate and share valuable information

Source of Truth Board (as it was called) was our main consultation and construction reference for the project. Together we design flows, align ideas and validate proposals, before creating prototypes.


My design process and some highlights

We used the Source of Truth board for design validations with the team. This facilitation was called Design Critique, where the team could validate their doubts and assumptions so that the development was fluid.

Research and User Validation - Inputs that made all the difference

We had a Research Specialist responsible for the research processes (described below). When I had the opportunity, I worked alongside the Researcher, learning more about his techniques and approaches within the Firm. I participated in user interviews and usability tests.

A good example of learning is that the project started with the premise of Mobile First but, after talking to some key users, we understood that its main use is given to iPads and Notebooks. In this way, we prioritize the design of screens in wide.

Why? Due to the need to write too many texts and notes, it was a unanimous decision to use larger screens and often use the keyboard when possible, even so we created a mobile version adapting with breakpoints to encourage use.


Hands-On Deliverables

My role was integral in delivering a full suite of user interfaces and experiences – from user flows and wireframes, prototypes and components, user testing and visual interface elements. My work was then validated by all stakeholders - users, developers, and business directors.

Managing components and variants

Before - After

From the starting version to the end, this was the visual switch for the tool. All these components worked together to make it possible resulting in outstanding success, delivering perfomance, encouraging feedback and providing user-friendly options on mobile and tablets.


UX Writing - Friendly and contextual

In the creation of creative texts (e.g. →),
I participated until we reached final ideas that were disruptive but within any cultural context and not offensive.

In systematic and tool action texts, we had a UX Writer focused on content production.

Personally, I have evolved a lot for having worked with one of the one of the "Big Three" management consultancies in the world. The expectation of excellence are daily, individualy and performing as a team. Synthesis, negotiation, presentation of ideas, facilitation were just some of the soft skills I was able to sharpen and receive feedback.

I had the opportunity to following our Research Specialist in his process. Feel like I've learned a lot from him about how to record the results of a survey effectively (Hard skills) and how to present these results to a completely technical team (Soft skills).
