Who’s Heinrich Schmid?

Heinrich Schmid is a large-scale German company, offering a wide range of construction services across Europe. With its extensive network of hundreds of branches and thousands of employees, the 100-year-old industry leader generates terabytes of data and handles thousands of mission-critical transactions every day.

What’s Our Partnership Like?

We have been collaboraring with Heinrich Schmid for the last 4 years. Although we are currently involved in a long-term partnership with the company, we started our journey together with our 100-day MVP model to quickly validate how well Heinrich Schmid employees would adapt to digital transformation. Starting from day one, our collaboration has been grounded in open communication and a transparent development process, with our work readily accessible on platforms such as GitHub and Jira whenever needed.

What’s the Project About?

After years of doing business in the traditional way, Heinrich Schmid realized that managing thousands of transactions on paper was no longer practical or efficient. In search of a more modern solution, the company decided to digitize their internal processes, recognizing that even SAP was unable to handle their problems.

To meet this challenge, Heinrich Schmid approached us to develop an internal app that would simplify and streamline their business operations. The app would allow employees to say goodbye to the struggles of working with paper and provide a single platform for conducting business with clients online. All files and information would be easily accessible with just a few clicks, bringing convenience and efficiency to the workplace. However, the initial uncertainty around whether Heinrich Schmid employees, who were accustomed to traditional methods of conducting business, would embrace the new system, was another factor that added to the challenge. 

What Did We Do?

Heinrich Schmid has various departments with different use cases. But for the MVP scope, we focused on the offer module they used to manage the bidding process of their projects. We then named our project, Baumappe. 

After 100 days, we launched the first version of the application. Following the release, Systemhaus, Heinrich Schmid's responsible technology unit, collected feedback from every branch using our product to evaluate its performance. The initial feedback was overwhelmingly positive, indicating that Heinrich Schmid employees found the app easy to use and integrated it seamlessly into their daily work processes.

With the validation of our product, we took the next step and continued the project through our  long-term partnership model.

What Kind of Team Did We Structure?

We built 2 dedicated and self-oriented Scrum teams following Scaled Scrum principles. These teams consist of Backend Developers, Frontend Developers, QAs, DevOps, Test Automation Engineers, and Scrum Masters.

What Services Did We Offer?

Web Development, Software Architecture, Quality Assurance, Data Engineering, Platform Engineering, DevOps

What Technologies Did We Use?

Azure Portal, Azure DevOps, Kubernetes, Terraform, Microservices, Micro Frontends, Feature-Toggling, Kustomize, Argo CD, New Relic, Grafana, OpenFaaS, Node.js, TypeScript, GrapQLl, React, Apollo, Apollo Federation, gRPC, Azure Service Bus

What’s the Result? 

We have provided Heinrich Schmid with a tailor-made super app that effectively handles the problems left unresolved by the SAP system they previously used. Today, over 5,000 employees across hundreds of branches utilize the app's cloud-based file storage, which enables easy management of nearly 100,000 projects and seamless sharing of millions of documents with just a few clicks. This streamlined system has transformed Heinrich Schmid’s business operations in a way that would have been unimaginable when managing thousands of transactions on paper.
