Problems with Non-ERP Systems
In-house design limits connectivity outside the company
Tendency toward separate IS’s within firm
lack of integration limits communication within the company
Strategic decision-making not supported
Long-term maintenance costs high
Limits ability to engage in process reengineering
Traditional IS Model: Closed Database Architecture
Similar in concept to flat-file approach
data remains the property of the application
fragmentation limits communications
Existence of numerous distinct and independent databases
redundancy and anomaly problems
Paper-based
requires multiple entry of data
status of information unknown at key points
What is ERP?
Those activities supported by multi-module application software that help a company manage the important parts of its business in an integrated fashion.
Key features include:
Smooth and seamless flow of information across organizational boundaries
Standardized environment with shared database independent of applications and integrated applications
Two Main ERP Applications
Business analysis applications
a.k.a. Online Analytical Processing (OLAP)
decision support tool for management-critical tasks through analytical investigation of complex data associations
supplies management with “real-time” information and permits timely decisions to improve performance and achieve competitive advantage
includes decision support, modeling, information retrieval, ad-hoc reporting/analysis, and what-if analysis
OLAP
Supports management-critical tasks through analytical investigation of complex data associations captured in data warehouses:
Consolidation is the aggregation or roll-up of data.
Drill-down allows the user to see data in selective increasing levels of detail.
Slicing and Dicing enables the user to examine data from different viewpoints often performed along a time axis to depict trends and patterns.
