Patent ID: 6973652

Claim:
A method for executing a series of sequential tasks existing within a system-level domain of a customer service computing system providing provisioning of meta-level domain products, each said product having features, and said features carrying an attribute prescribing a related locking milestone, the method comprising the steps of: (a) designating one or more of said tasks as a milestone; and (b) executing said sequence of tasks, and for each said milestone task: determining, as a precondition, whether said feature has attributes associating it with a customer so as to be valid, then (i) making an enquiry of a related said product feature to determine whether the task milestone corresponds to said locking milestone and, if so, placing the said feature in a locked state such that its attributes cannot be changed until execution of said task sequence is complete, and then (ii) continuing with said execution, whereby milestone tasks are reflected as aspects of said product features in the meta-level domain, and there is the further step of defining milestone status in said meta-level domain.
