PSI Framework
As customers are seeking out more “off the shelf”
solutions, PSI has taken the lead on innovative solutions with currently
available and applied technology. These are systems and solutions that support
your business objectives, meet the functional requirements, can be integrated
with existing systems, can be supported with existing staff, can be implemented
efficiently and easily, and justified through True Cost of Ownership (TCO). The
key elements that PSI included in its implementation include compatible
solutions for your enterprise:
- PSI is closely aligned with
your IT infrastructure. This includes but is not limited to:
- co-existence on the current
network and the ability to operate upon the network topology
- the ability to readily
integrate to existing systems
- the ability to support
native integration with back office products and processes
- the support of the various
distributed uses
- the ease that users, support
staff, and maintainers can utilize the product
- PSI is closely aligned with
your business processes. Since an off-the-shelf solution will have the lower
TCO the following elements were considered:
- The PSI products are focused
on automating business processes in the distribution operations center.
- Any administrator can
quickly set parameters adapting the system to meet your business processes
and does not require integrators, system delivery specialists or
customization to do so.
- For the business processes
that continue to remain manual activities, these are easily implemented
around the current tools the utility has in place. Native back-office
integration is supported through the use of the Microsoft Office product
suite.
- It is easy to implement and
support the on-going tasks that maintain the system when in production.
- It is easy to support and
maintain the system in a production setting.
- Standard infrastructure
components, in addition to the production system, are used to support,
maintain, and service the product. It doesn’t take special hardware or
software to support the production system environment.
- The PSI system is well suited
to align with existing data and models of the utility.
- The PSI system can begin
from existing data and sources of this data without the need for a large
scale data conversion effort as a starting point for the project.
- Benefits can be realized
from the system even when data sources are not complete and have
relationship inconsistencies between them. The system provides improved
benefits as the data is cleaned up over time.
- Existing systems and data
sources can be readily integrated using standards-based data exchange
formats, data content specifications, and data transport mechanisms across
the enterprise network media.
- Based on an ROI value system
for feature/functions (data enables functionality), a staged approach to the
prioritized utilization of the existing data/data sources can be readily
implemented.
The PSI specific implementation architecture that meets
these requirements and more is described in the following sections. It is based
on a technology infrastructure using current well-accepted technology components
to form the basis of the system. It includes a model driven architecture that
defines the core modeling methodology, integrated development environment, and
support rapid implementation and delivery capabilities. The implementation
architecture also defined the integration components enabling the data exchange
between existing systems and the PSI model.
