Success Stories

Every project is an opportunity to demonstrate our commitment and technical capability. From process digitalization to the development of custom solutions, our success stories reflect how we help our clients optimize operations, improve control, streamline decision-making, and generate sustainable value.

We faced the challenge of digitalizing the monitoring of maintenance orders in an organization with multiple key processes. We created a PowerApps application that automatically connects with Excel files, allowing for constant information synchronization. We included practical functions such as QR code scanning and user registration with login. This solution enabled the client to optimize the registration, tracking, and visualization of orders, significantly improving operational efficiency and reducing manual errors.

An automotive sector client needed to establish a clear authorization flow for the transfer of parts between plants. We implemented a workflow system that allows for detailed tracking of each step and required authorization in the logistics process. This solution helped the client strengthen their internal controls, reduce delays, and ensure that every movement of parts was properly authorized and documented.

We were tasked with developing a digital solution to capture specific user requirements using an accessible and flexible tool. Utilizing PowerApps, we designed an application capable of quickly responding to user needs, improving communication between departments, and reducing response times. The solution was well-received for its practicality and immediate impact on workflows.

A company with multiple business lines required a centralized solution to visualize key metrics. We created a web portal that integrates embedded Power BI dashboards, offering a unified view of the performance of all the client's units. This tool enabled senior management to make more informed decisions by having reliable, real-time data from a single platform.

An engineering department requested a solution to control technical changes with greater traceability and visibility. We developed a system that centralizes the authorization, tracking, and safeguarding of critical information related to engineering changes. The solution offers a clear summary of the progress of each modification, along with a simple interface to facilitate interaction with directors. With this, the client improved document control, inter-departmental communication, and efficiency in implementing changes.

We collaborated with an organization to improve their Bill of Materials (BOMs) application. The objective was to offer greater visibility and tools throughout all steps of the process. We implemented various improvements and adaptations in their application, optimizing the navigation, visualization, and editing of material structures. The result was a more efficient, intuitive tool, aligned with the operational needs of the engineering and production departments.
