T-mobile: customer experience went omnichannel


The Story of T-Mobile

T-Mobile is a well-recognised mobile operator. The Polish subsidiary is the 4th biggest operator, having a 20% market share. Being under competitors' pressure, the company must continuously improve its offer. Excellent self-service applications are a strategic goal that allows for standing out in the market.

Self-service before the iPhone and Android relied mainly on IVR and web applications. The voice channel was in the spotlight. The mobile applications boom changed the way how customers interact with organisations. Telecommunication companies such as T-Mobile started to rapidly extend their communication channels.

The Challenge

After launching many self-service applications, T-Mobile recognised that managing multiple channels in parallel: 

  • Creates difficulties in maintaining consistent communication
  • Slows down the delivery of changes in self-service and back-office applications
  • Increases the cost of software modification across many channels

The challenge pointed out by the customer focuses on three “hows”

How to speed up business level configuration?

How to unify the configuration across channels?

How to reduce the costs of the development and modifications?

Why did T-Mobile choose Eversis?

Eversis was the only company that could deliver consultancy services with a strong technical capacity. The customer appreciates the business level and customer experience know-how.  A solid technical team guaranteed end-to-end project delivery.

What we delivered

Eversis team implemented and deployed the Alvaria CX Suite (formerly Aspect CXP), an integration platform dedicated to self-service applications. The platform managed the most critical self-service process, including:

  • Promotions and sales communication (including marketing consents),
  • Bills, invoices, billings, and the status of the payments,
  • Status of the services, enabling/disabling services,
  • Contracts and owned devices,
  • Help desk and customer support.

Thanks to the platform, the business owners, marketing and sales teams can adjust communication flows to their needs. The implemented solution allows designing, configuring, and deploying communication flows and management of business rules without programming.

Alvaria CX Suite flexibility gives new possibilities to improve self-service channels by:

  • Complex architecture which relies on many technologies
  • Vendor lock, which slows down your development process

All self-service applications and communication channels exchange the data directly with back-office systems.

It causes many issues, such as:

  • Complex architecture which relies on many technologies
  • Vendor lock, which slows down your development process

We achieve what the customer required, in particular:


of backend reconfiguration is performed within the platform


application development cost reduction


unification of common rules across all four communication channels

A business rules engine with a graphical interface changes the maintenance of self-service processes. The marketing and sales teams learned to change standard configuration parameters such as promotion and sales messages, and service announcements. Building more complicated rules, which rely on customer profiles and buying experience becomes feasible from the GUI. It cuts off most of the marketing and sales changes, which needed coding previously.

Finally, all teams have a bird-eye view of how the systems interact with end-users. Transparency allows the unification of common components across the channels.

Additional benefits

Apart from the project's main goals, the customer gains new possibilities for self-service development.  Connectors framework for seamless integration with new communication channels allows easy integration with chats, virtual assistants, and bots. The platform flexibility opens the solution for advanced AI/Machine Learning algorithms for predicting the next best action from the customer.


Our customers now have the same information and the same processes available on any channel, thanks to the integrated platform designed and implemented by Eversis.
