Abstract: Methods and apparatus for executing a series of sequential tasks existing within a system-level domain of a customer computing system providing provisioning of meta-level domain products are disclosed. For each product or product action (202), one or more sequence of tasks (250–272) is defined. Within each sequence, one or more tasks are defined as milestones (250, 252, 254, 260, 264, 270, 272). The sequence of tasks is executed, and at each milestone task, an enquiry is made of a related meta-level domain feature to determine whether, as a precondition, it has attributes associating it with a customer, and further whether the product feature holds a locking attribute that corresponds with the milestone task. If so, the execution is continued, and the product feature is placed in a locked state such that its attributes cannot be changed until execution of the task sequence is complete.

Abstract: Methods and apparatus for mapping an action, occurring within a customer servicing computer system, from a meta-level domain to tasks within a system-level domain are described. The actions are defined to have a plurality of data-fields, each of which has attributes. For a subset of the meta-data fields, and for each field within the subset, the mapper key is formed from a portion of the attributes. Each mapper key is compared with a set of task templates. The task templates define a sequence of system-level domain tasks. If there is a match of all the mapper keys with a respective template, then a system-level domain task sequence is formed to give effect to the action as the collective tasks of all task templates.
