This is a case study based on my user experience research with a real client, Cucko, a Brazilian club from Porto Alegre, for whom I developed an exclusive app for its customers. I emphasize that the user discovery and solutions realized occurred before the covid pandemic.
Design Process
I utilized the double diamond diagram system to design the project (discover, define, develop, and deliver).
General Problems
•  Brazilian inflation's effect on food/beverage prices causes regulars to stop going.
•  When the club's crowded, there's discomfort due to long lines at the bar and paying the final bil

Project Goals
• Discover and comprehend Cucko's pains and satisfaction, as well as who his customers are.
• Figure out how to make it a more pleasurable experience for them.
• Validate a new digital product that distinguishes itself from the competition.
To understand the scenario with which we are dealing while implementing the project. We employ both discovery methodologies, as well as qualitative and quantitative research.
In the quantitative research, we used a survey with some of the most diverse club regulars to find out what they like and dislike about the club experience. Also included is an in-depth interview with five long-time partygoers.

Quantitative Research
It was created a simple and friendly questionnaire for the users' consumption habits, which received 30 responses. The following are the most important points:
Qualitative Research
We interviewed five long-time partygoers and asked them about their relationship with the club, whether they have a great party story, something that happened there that they didn't like, how they see the club as an inclusive venue, and the issue of higher food and beverage prices.
The following are the most important user testimonials:

Research Findings: 
We discovered some interesting things about the user problems and their passion for the club during the user research. That demonstrates that they are evangelists' customers because they invite their friends to the parties and talk about the place with people outside the club's bubble.
We created some patterns and hypotheses based on the user research findings to create personas and a benchmark with the key players in the Porto Alegre nightlife.

Personas are divisive, but we used two based on real people from our user interviews. Many different types of people enjoy the club, but in this case, we have discovered some key behavior patterns in our regulars. Focusing on these two types of people makes it easier to figure out the features of the digital product:

Despite how different the personas are, we discovered some common issues between them:
• Discounts on drinks and food are required. 
• Due to high demand, the club's service is of poor quality.
• Long queues for beverages, food, and paying the bill.

Competitor Analysis:
We examined two official club web pages from Porto Alegre and So Paulo with the same audience to acquire a better understanding of how they use digital platforms to retain their regulars. Highlighting the best and worst features of each website feature During our study, we discovered that none of them had an official mobile app. As a result, we may learn about the most important components of a digital solution to the client's problems. 
So we use the plus and deltas to show it practically:
User Journey
We discover how each website operates to provide a client experience after researching its rivals and features. With that information, we design a user journey on the Cuckos official website and an offline journey at the club to identify the club's weak spots and consumer requirements for a positive experience. We employ both of the established user personas.
We might define what works in a new digital solution by learning what works in both offline and online journeys. Customer loyalty enhanced by cheaper promotion rates and the ability to avoid long lineups can improve the club experience and provide more enjoyable customer service.
Now with the possible solutions from the previous step, we can prioritize the features and resources to build a minimum viable product. So in this phase, a mobile app could be interesting for the club.

Moscow Method
We use the Moscow Method to prioritize resources and features, and we take what matters for a strong customer experience on online and offline experiences, to make people's life easier, but we also consider what may be improved. 

We understood from analyzing user behavior that an independent digital platform apart from social media may solve some user experience issues. Because it appears to be quite useful for folks using in a party situation. In this MVP, the goal will be the most wanted club services according to our research by the Moscow Method.

• Food and beverages promos.
• Birthday promo with guest lists.
• Exclusive discounts for the week's events.
• The option for locals to pay their bills using the app eliminates long lineups.
With these user goals in mind, we built a sitemap that demonstrates how the user may meet their goals in a clear and simple way. Even in a place like a nightclub with low lighting and a large crowd.
We designed in a very minimalist style, looking for the simplest way for the user to achieve their goals. Given that the user can select a beverage promotion in the midst of a packed party, displaying the QR code for the bartender taking the order. And the ability to pay the final bill without having to go to the pay box and avoid long waits.
User Tests
Based on the client's visual identity, we developed medium-fidelity user interface screens using wireframes. So, with Adobe XD, we created an interactive prototype. Additionally, we conducted additional user testing with club regulars. We invite them to do some easy tasks like:

• Send a list of birthday discounts.
• Pick an event and submit the names of your friends for the guest list.
• Pick a promotion.
• Retain a QR code from the selected promotion.
• Pay the last invoice.

Using the Zoom program, the test was conducted remotely with 5 regulars. Some of these individuals served as the basis for the user personas. Most of them completed the challenges quickly and without any difficulties: 
15 seconds: pay the final bill and pick a promo.
10 seconds: send friends' names for the discount list and redeem a QR code.
Users generally appreciate how simple it was to utilize the program. They also enjoyed the option to pay the bill without visiting the cashier. They claimed that it could benefit the club by increasing the long waiting lines.
Finally, we reach the double diamond's final half, where the MVP is available. With the results of the user testing, we made a few minor changes to the interface to improve the user experience. Make it simpler:
User Interface
A look at the app's interface and key features.
Feature Pay the Bill
This is probably the most important feature because it solves a real-world issue, such as the inconvenience caused by customers when the club is crowded. At the time of checkout, the user can enter the order number. And it can pay with a credit or debit card to generate a QR code which will be shown to the hostess at the club's exit.
Feature Promotions
This feature provides discounts if the user purchases food or beverages through the app, and it helps to improve people's flow at the three bars that operate within the club. Some minimal illustration icons for food and beverages were made, resulting in a more contemporary visual design. The checkout screen includes a tiny banner that suggests the user purchase accompanying goods.
Ticket discount lists
This was the sole feature that remained on the original club website. You can send ticket discount lists with your friend's names and birthday guests, ensuring a significant volume of people using the app and making the customers' journey smoother.
This is crucial for the Cucko's regulars because the general public deviates significantly from the normative standard, and the club serves as a second home for them.
As a result, we used real photos from the regulars to illustrate the user interface screens, forming an effective link with them.
Here's a look at the most recent prototype version.
Final Thoughts
Despite of the user tests, this product's responsibility does not end there. We are always trying to improve, adapting to changing scenarios, and seeking new user experiences. We must always put human valor into our work in order to bring delight and happiness to our users. If they are pleased with the product, they can recommend it to others and become evangelists.
Self-service terminal
In a post-pandemic scenario, even if it is risky for the club to implement its own app, this system can be readily transformed to self-service terminals within the club. In this situation, the product will be emphasized by paying final bills and purchasing food and beverages. The user can print a ticket with a QR code and show it to the bartender or the hostess to exit the club without having to wait in large lineups.
It demonstrates that the user experience can be flexible and that the product solution may be implemented in a variety of situations.
Thank you for reading my case 🙂
