Context

Context

Pão de Açúcar is a retail chain that handles a high volume of orders through digital channels.

The current system was experiencing problems with orders that were incorrect, damaged, or different from the original purchase. This scenario generated a large number of customer service calls, which affected operational efficiency and user experience.

Our challenge was to develop a solution that would automate the process of reporting problems with orders, giving customers more autonomy and agility, while reducing demand on the service team and generating savings for the business.

Research and Discovery

Research and Discovery

We used an email survey to gain insight into customer experiences with service channels and to map the pain points and behaviors of GPA customers when their purchase includes missing products.

We got good results with 109 respondents to all 33 questions.

Mapping behavior

Mapping behavior

As a starting point for the project, we carried out a survey to map the profile of users and understand their behaviors, preferences, and main pain points when dealing with this type of problem. The research helped us identify the biggest frustrations during the purchasing experience, as well as validate hypotheses about bottlenecks in the resolution process.

Mapping of exchange experiences and missing products

We tried to understand whether there was a recurrence of unforeseen situations when receiving products online and whether these problems were resolved satisfactorily.

Creating a conversational system

Creating a conversational system

A user-friendly conversational interface was created, allowing customers to navigate through steps, select their issues and products, and ultimately choose their preferred method for receiving a refund or having the product redelivered.

Understanding the preferred channel of customers

We found that the telephone is not only the most commonly used communication channel, but it is also regarded as the most effective method for resolving issues. To gain a better understanding of this, we conducted a more in-depth usability test to evaluate whether the proposed solution aligns with the user’s perception of this channel.

Usability test

Through user testing sessions, we found that navigation through the experience was fluid and intuitive. However, there were suggestions for improvement, such as making the "I need help" button more prominent and tweaking the message box to allow users to better describe their problem.

Gain of Time and Agility

Conversational Interface - The flow allows the customer to autonomously report incidents related to missing, damaged, or incorrect products in their shipments.

Auto-resolution - Users can quickly identify which item has a problem, select the type of event, and choose the form of compensation they want - all without having to contact an agent.

Status tracking - Track the progress of a request in real time, from confirmation of submission to completion of resolution.

Projected impact

Together with the customer support department, we were able to make impact projections with the implementation of the MVP, which can be expanded to other types of problems.

Key Learnings

Changes in the user's routine

Changes in the user's routine

Customers aren't always willing to accept change, even when it's designed to speed up their journey. Understanding their real needs and proposing simple solutions can have a greater impact than you might think.

Often, it is in the limitations that we find the best opportunities for innovation.

We had the support of a consulting firm for the recruitment, testing, and user interviews.

My role was to coordinate these stages, work behind the scenes during the sessions, and be responsible for collecting and organizing the insights - a challenging and very enriching experience.
