Railway Operator – “Chave na Mão” App

Railway Operator – “Chave na Mão” App

“Chave na mão” application, developed with Scrum framework by CINQ Technologies, helped the logistics company to increase operational efficiency.

Mobile Applications

Client Overview 

Rumo is the largest railway operator in Brazil and offers logistics services for rail, ports, and storage.

Engagement Situation & Challenges

There is a process known as a “maneuver”, that takes place in the loading and unloading yards, such as Santos and Paranaguá (Brazil). These maneuvers are planned at the Rail Yard Control Center (in Portuguese, CCP) by the operators and are communicated via radio for the field team (machinists and maneuverers).

Rumo’s main challenges in this process were:

  • Optimize communications between CCP/maneuverer/machinist, replacing radio communication with an application;
  • Increase the visibility of the real-time process;
  • Access field data to assist in future analysis and process optimizations.


“The biggest challenge from the business’ point of view was to understand the customer needs to find the best way to replace the radio communication.”

Daniel Bastos – Scrum Master


CINQ’s Solution & Contribution

For the application development, a dedicated team of 6 employees from CINQ Technologies worked using the Agile Method and Scrum Framework, seeking closer communication with the client and better visibility of the project’s progress.


“CINQ’s working mode is dynamic and therefore, every delivery we saw what the team had developed and tested. With CINQ, we had agility in identifying the situation and we worked together to reach the best solution proposal.”

Rafael Pinto- Product Owner


A UX (User Experience) project was developed by the team’s designer for achieving Rumo´s objective to replace the radio by the “Chave na mão” app. This phase was essential to the success of the project as it was possible to understand and identify the user’s journey and think about Interface solutions that were ideal both from the design standpoint and from the technology used.


“At CINQ, we include the user experience from the beginning of the project; it is common for designers to be present for surveying user stories with customers, helping to understand the user’s challenges and co-creating a solution. User Journey mappings and field visits are also made to understand all the contexts of use of the future product or service”.

Raquel Prado–Usability Analyst


During the project, the team identified functionalities that were not a priority at the time and that could delay the delivery of the system. Therefore, backlog refinements were made with the Product Owner.


 “Using the Scrum framework allows us to change the project’s scope, adapting deliveries according to the customer’s needs and the team’s perception and learning during sprints”.

Daniel Bastos–Scrum Master


Tools & Technologies used


The biggest technical challenge of the solution was to work with legacy software, which would be integrated with the application with Oracle SOA technology.

“CINQ already knew the technology and we could rely on its support for maintenance, even our operations running 24 hours a day.”

Rafael Pinto – Product Owner

Key Benefits

  • Customer 100% satisfied with the project, according to carried-out quality research;
