A set of pre-defined datacenter IT solution tasks which are to be
performed by a user for setting up or for extending a datacenter is
provided for a pre-defined IT solution. Groups of basic tasks and
learning tasks are provided such that each learning task comprises one or
more basic task. A sequence of interface tasks is assigned to the basic
tasks and learning tasks. An interface task provides a predefined
instruction or set of instructions for validation or for verification of
the correctness of the performed learning task or interface task. This is
done by evaluating a characteristic behaviour of the datacenter and not
necessarily by monitoring each step of the user who is fulfilling the
tasks.
