provided in the
Template overview
section.
This template describes how to represent a UK_Defence change impact, using
Applied_activity_assignment
This information object represents an impact that the related change would have if it were implemented.
For further information about the representation of a change impact, see below.
This information object represents an impact that the related change would have if it were implemented.

Table 1 — Change Impact attribute details
The EXPRESS-G diagram in
Figure
2
shows the templates and EXPRESS entities that are required
to represent the template
"change_impact".
The text highlighted in blue shows the template parameters.

The graphic for the template to be used in other EXPRESS-G diagrams
is shown in Figure

below.

The following input parameters are defined for this template:
This is the Identifier of the Change Impact.
The organization that created the associated identifier. Additionally
a Person or Information System could be defined when either of these are the source; see Identifier template characterizations
This is the name of the type of the class used to classify the identifier and so
provide the role or reason for the identification.
The following classes and their sub-classes can be used:
This is the reference to the item to which the impact relates.
This is the reference to the Change that causes this impact.
This is the description of the impact that the Related Change will have.
This is the estimated number of units that are affected by the change. The datatype is always 'any_number_value'
and should not be registered together with the value, i.e. enter the
value as a number, without datatype.
This is the categorization of the Change Impact.
The following reference parameters are defined for this template:
%^target = $change_impact.impact%
Allow the
Assigned_property
entity instantiated in this path to be referenced when this template is used.
%^target = $change_impact.property%
The following parameter combinations specify a uniqueness constraint:
Unique constraint: Unique id
Each instance of the
entity
(
Applied_activity_assignment)
within the data set shall be uniquely identified
by a combination of the following parameters on this
template (change_impact) namely:
related_change,
ID.
The
instance is
referenced by the following template parameter:
impact.
The Id and change of the product should only occur once in a data set.
The instantiation path shown below specifies the entities that are to be
instantiated by the template.
A description of templates and the syntax for the instantiation path is
provided in the
Templates Help/Information section.

The following entities are instantiated with attributes as specified:
The instance diagram in Figure

shows an example of the EXPRESS entities and templates that are instantiated by the template:
/change_impact(ID='imp444', source_organization='BAE Systems', ID_type='Identification_code', impacted_item='@33', related_change='@118', description='will stop wet weather work', quantity_of_items='ANY_NUMBER_VALUE[2]', type='Hydraulics')/
(an illustration of the consolidated change_impact template is shown in
Figure
5 below.)
Figure 4 — Entities instantiated by change_impact template
The instance diagram in
Figure
5
shows the graphic symbol for the template that is to be
used in other instance diagrams. The example template is:
/change_impact(ID='imp444', source_organization='BAE Systems', ID_type='Identification_code', impacted_item='@33', related_change='@118', description='will stop wet weather work', quantity_of_items='ANY_NUMBER_VALUE[2]', type='Hydraulics')/
Figure 5 — Instantiation of change_impact template
The following section details how the
change_impact
template can be optionally characterized by assigning
other constructs to it. These are characterizations commonly
applied to the template. The ISO 10303-239 EXPRESS model may enable
other assignments to the entities instantiated by the template.
The EXPRESS-G diagram in Figure
6
shows the possible characterizations of the template
"change_impact".
Figure 6 — Characterizations for change_impact
The following characterizations may apply:
Characterization Assigning properties
NOTE this characterization is optional.
Properties, e.g. estimated total cost; estimated total non recurring cost; estimated total recurring cost;, can
be assigned to a typical activity.
A property is represented using templates
assigning_process_property
and process_property_numeric.
NOTE
The assignment of process properties are described further in capability C077: assigning_process_properties.
/assigning_process_property(property_class_name='Estimated_total_ cost', property_ecl_id='urn:plcs:rdl:uk_defence', described_element='@117')/
other possible values for property_class_name could be "Estimated_total_non_recurring_cost" and
"Estimated_total_recurring_cost".
/process_property_numeric(value='750', unit='Pound_sterling', unit_ecl_id='urn:plcs:rdl:uk_defence', si_unit='false', context='Numerical_representation_context', context_ecl_id='urn:plcs:rdl:uk_defence', property='@10')/
NOTE
Presuming that the example of template assigning_process_property is given the value @10.
