ERP Enterprise resource planning (ERP) makes
timely information easily available for analysisand decision-making in companies of all sizes.
ERP systems monitor business functions inreal-time to provide timely information inmanufacturing, finance, distribution, sales orhuman resources. A strength ofERP systems
is that they integrate data across allfunctions.
For example, a manufacturing supervisorwould be notified when raw materialinventory falls below a set floor.

Advantages of ERP
Eliminates costly, inflexible legacy systems
Improved technology infrastructure
Improved work processes
Increased data access for decision making
Current business conditions make enterprise-wide accessibility of information a key to success. ERP software offers that possibility.
Deploying an ERP system allows a firm to replace numerous separate, sometimes isolated, inefficient legacy applications with a singleset of integrated products. This improves the efficiency of systems and decreases the cost of maintaining old systems. This improves
an organizations ability to adapt to changing conditions. Implementing an ERP system also gives an enterprise the chance to upgrade
and standardize hardware, software and databases, reducing support and operations costs.
ERP systems are designed around the most effective and customer-oriented business pract ices found. Thus, deploying an ERP system
will help an organization follow the industrys best practices. Although the adoption of improved work processes can be beneficial, as
noted on the next slide, this can also be a disadvantage. Often established processes must be re-engineered, possibly causing
dissatisfaction or turnover among experienced employees.
Since ERP systems maintain an integrated database, decisions can be made based on enterprise-wide data. This is far more efficient
than trying to coordinate decisions across units.

Disadvantages of ERP
Expense & time
Radical change
Integrating with other systems
One vendor risks
However, ERP systems are time-consuming, expensive, and difficult to implement.
Some companies have spent millions of dollars and many years implementing ERP systems
not always with successful outcomes.
Many companies have also had problems making ERP systems work with existing systems, adding to the expense and difficulty of deploying ER
After investing so many resources in implementing ERP, switching costs are very high,
so an ERP vendor essentially holds a business that uses its system hostage.
Even with these problems, however, many organizations are successfully using ERP systems.
