1. Data exchange blocks;
Software applications built to run on different operating systems cannot be connected to run together on the same operating system. We need to re-entry data from one system to another system in order to exchange information, thus leading to data inconsistency;

What ERP Systems Can Offer to an Enterprise? – Benefits
ERP creates value through

Advantages and Disadvantages
Factor Pro Con
System Integration Improved understanding Less flexibility
across users
Data Integration Greater accuracy Harder to make corrections
Best Practices More efficient methodsImposition of how people do their
work
Less freedom and creativity
Cost of computingMore efficient system
planned Changing needs
Under budgeted training expense
Hidden costs of implementation

ERP Modules
Reasons of designing ERP systems in Modules
1. Obtain specific functionality
2. Cost
3. Implement the system in bits rather
than bring entire massive system online
at one time

Ways to Developing ERP SystemMethod Advantages Disadvantages
Develop in-house Best fit with organizational needs
Most difficult to develop, most expensive, Slowest
In house system with vendor supplements
Gain commercial advantages combined with organizational fit
Difficult to develop, Expensive, slow
Best-of-breed Theoretically gain best of all systems
Difficult to link modules, slow, potentially inefficient
Customized vendor system
Retain flexibility while keeping vendor expertise
Slower, usually more expensive
Selected vendor modules Less risk, relatively fast, least expensive
If expand, long run time and cost higher
Full vendor system Fast, less expensive, efficient Inflexible
Application service provider
Least risk, least cost, fastest, least subject to vendor change
At the mercy of the provider, no control, and subject to price increases
