This makes our activity very challenging both on business and IT services.
  • To accommodate this fast changing world Luminus IT has organized its delivery in a bimodal way where on the one hand changes are delivered directly by BizDevOps teams organized in Release Trains (i.e. the teams work according to a scaled agile framework) and on the other hand through Big Projects which are managed by project managers.
  • The last years some important investments were done to standardize our IT platforms. Nevertheless we still have some IT debt coming from our Luminus history.
  • Luminus has a multi technological environment where besides applications also topics like infrastructure, database, security and impact on operations needs to be taken into account

The aim is to reduce operational business cost. We are in a face to replace legacy applications by new COTS applications. This will require complex integration to existing landscape and also includes the implementation of a new Operational Data Store and Data Management System. 

The current IT infrastructure, which is becoming obsolete, is a mixture of applications (homemade and COTS) and technologies (excel/access, .NET, JAVA, APEX, DELPHI, VB6) and strong interfacing (DLL, web services, ODBC, FTP, sFTP, file transfer).
