Overview

Creating models

In Tivoli Change Management, a model is a template for changes that occur often or for changes with common data. You create the model for a change category, defining values for the elements of the change that are common to all changes of that category. Then, when a change is requested for the category, the elements defined in the model are automatically added to the change. These fields cannot be modified by the user unless:
  • The user has TCM Model/Rule Value Override security rights
  • Allow Model Bypass is selected for the change category associated with the model

Business rules can also override data inserted from a model.

Using models offers the following advantages:

  • Provides a structure for changes
  • Provides better control for administering changes

You can have more than one model per category, assign a priority when there are multiple models for a category, define a default model for a category, and allow users to decide whether to apply a model or complete a change manually.

You create models from either of the following:

The Model dialog box

You can create models from the Model dialog box. The Model dialog box contains these tabs:
Tab Function
General You specify general information, including the change category (required), status and risk codes, costs, and attached files. See Creating a new model.
Approvals You specify approval requirements, are specify the individuals or organizations who are responsible for approving changes created from the model. See Specifying Approvers.
Impacts You specify impact requirements, which specify the impact analyses that must be performed when a change created from the model is requested. See Specifying Impacts.
Tasks You specify tasks, which are steps that must be performed to complete a change created from the model. See Specifying Tasks.
Activity Activities, which are subordinate changes to a parent change that is created from the model. See Specifying Activities.

Note: You use the Model dialog box to create a specific model. You use the Models dialog box to select a model to edit, view, or delete. For more information, see Maintaining Models.
