Business Situation 
  • Tesco seek to continually reduce both existing and future costs of systems management and administration services.
  • Implementations of Active Directory were already in train in the UK, Central Europe and Asia.
  • Many UK projects had global dimensions and others in Central Europe and Asia needed a Global Design for Active Directory.
  • A Global Active Directory design was required in order to provide secure global 'collaboration services'.
  • In addition, Tesco also wanted a Migration Plan to achieve Active Directory convergence.



Working with a global Tesco Team and utilizing the Avanade Solution Delivery Methodology, the team is delivering an agreed Global Active Directory design taking into account specific needs such as:

  • Tesco's short & medium term Business Strategy
  • Delivering design and migration decisions as soon as they become of value to current projects/parties that await final delivery
  • A design that enables Tesco to maximise the realisation of benefit of implementing Collaboration Services, Security & Authentication Services, Object Naming Standards and Group Policies, Systems Management and Software distribution
  • The team is also providing a Migration Strategy. 


  • A Global Active Directory design which:
  • Is robust, reliable and scaleable and which meets Tesco's global needs
  • Provides a migration plan that shows how and when global convergence of Active Directory Services can be achieved
  • Defines a migration and coexistence strategy from existing technologies and directories and which ensures business continuity
  • Defines an implementation approach that is flexible enough to cater for the different time zones of the business units involved
