Why using BSM Planning Wizard?
• Network expansion/change - frequent O&M
work
• Direct interface with the Network, risk for
introducing errors
• Difficult to keep track of all dependencies
between parameters
• Difficult to find inconsistencies and handle
conflicts

Why using BSM Planning Wizard?
• Low-level parameter settings require deep
knowledge
• Many parameters are set by default values
• Multiple use of BSC resources

Definitions – The Planning Wizard
• A framework for execution of work orders.
Assuming that a work order is executed from
a wizard using a consistent configuration as
input, the wizard guarantees that the
configuration is consistent after the work
order has finished.

Definitions – Work Order
• A (configuration planning) task performed as
an atomic operation, in terms of changes to
an existing configuration, executed normally
by one single user within a very limited
amount of time. Each work order is divided
into one or more steps each supporting one
well-defined part of the task.

Definitions – Step
• The smallest part of a work order. A work
order step supports one well-defined part of
the work order, consisting of a number of
planning (or UI) attributes. In addition a step
might have a fine-tune step handling rarely
changed attributes

Definitions – Planning Attribute
• Planning attributes (also called UI attributes)
are attributes visible to the user of the wizard.
Depending on the status of an attribute, the
user might be able to change it.
