• 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
