Enterprise SystemEnterprise System (ES)* is an information system that supports business processes spanning over several departments or an entire organization. Data belonging to business processes are completely supported by IS, that is, all data are in electronic form.

Sales & Delivery Process

Marketing Process Production Process Supply Process

Management Process (operational, strategic)

Accounting & Finance Process

IS Development & Maintenance Process

Departments covered by ES: purchasing, inventory, production planning and scheduling, accounting, finance, HR, sales… almost any.*ES typically performs functions of TPS and MIS. With additional modules, ES works as data-driven DSS.ES are developed differently than other IS. Software is sold in packages, then configured to meet a company’s needs. **

Enterprise System Design

• The core is modules called ES Engineand Broker. Business processes are mapped in there.

• Centralized DBs used by ES supply data to business processes defined by ERP modules (accounting, finance, HR...)

• ES can use various database brands (e.g., SAP ES often uses Oracle databases)

Corporate centralized databases

Databases for Enterprise System

Databases that support ES may have tens of thousands of tables. High complexity.

Benefit from centralizeddatabases is that an entity is defined just once and so used across company departments. This improves data quality (next slide).

Purposes of ES (ERPS):1.The main purpose is to provide an integrated view of a company’s operations. This is possible owing to centralization in corporate data management. Primary beneficiary is executive managers.2. The integrated view allows for more informed decision making because data are:

- more consistent *- more complete – reports from ES reflect a whole company - more accurate** - more timely***

Department-specific and Corporate-wide reporting

Billing Record: CustomerBillingID, Date, Amount, Payment Method

Customer Support: Customer ID, Complaint, Customer, Date

Market management entities: Segment, Promotion, Campaign, Channel

Corporate centralized Databases

Data Warehouse

Data Warehouse (DW) is a large repository of data extracted from corporate databases. Thissoftware is purchased separately from standardES software.

DW is not relational databases, but has its own tables, keys, and data models. DW is used for building data cubes.* The capability of data cubing makes ES a data-driven DSS.

Enterprise System Vendors

SAP (Systems, Analysis and Products, Germany).

Oracle, PeopleSoft, J. D. Edwards (U.S.)

Microsoft Dynamics, aimed at smaller companies

SAP Business One is competing product

SAP BusinessByDesign

On-demand SaaS (Software as a Service – a method of renting Enterprise System services that are offered by an external party).

Instead of buying and owning software and hardware and operating ES on their own, a company rents the ES services.

This is a new method of managing information systems in general.

SAP• SAP is a software package for enterprise systems. It captures largest

global market share.

• Company was formed in Germany in 1972.

• SAP’s goal was to develop a standard business software that could be configured to meet the needs of a particular company.

• SAP’s founders wanted to:

• Make data available in real time (without delay)

• Enable users to work on a computer screen, not paper

• In 1972, these were big goals

• We will use SAP in the lab. It is a complex system and requires attention to details and – patience!

Why Is Knowledge of SAP Useful?

13

• SAP used much in Manitoba• Provincial government• Manitoba regional health care• Manitoba Hydro• Blue Cross• Deloitte (a global accounting & consulting company)

• http://www.deloitte.com• You can increase chance to be hired if you have some

exposure to SAP.

14

Enterprise System Costs• Initial tangible costs of an Enterprise System:

• Software and Hardware purchasing price

• Configuration cost (costs of setting up ES)

• Training cost (users need to be trained to use ES and new processes)

• ES (like SAP) may require big changes in business processes. This may stir up employees’ reluctance or rejection of ES intangible costs.

• A large company, with over 1,000 employees, can spend from $50 million to $500 million on an ES. ES is a “Cadillac” of information systems – it may cost a lot!

• Management should have a clear picture of total cost of ownership though whole life of system* before deciding to invest in ES.

15

ERP System Benefits• Better coordination between organizational functions, as data

flow smoothly throughout the whole enterprise.

• Reduced complexity created by different departmental IS (data must be reformatted to be shared across different departmental systems).

• Improved control. (Management value; a business document or even a single piece of data can be tracked down)*

• Better decision-making based on better data (see before) - readily available and integrated data; reports covering entire company. (Management value).

• Increased speed of processes. (Value shared by the entire organization).

Summary

Enterprise System (ES) (or Enterprise Resource Planning System – ERPS) is an IS that supports business processes which run across departments and may cover an entire organization.

Data management is standardized to provide an integrated view of business – ES is a TPS/MIS for whole enterprise. With additions, ES can be used as a data-driven DSS.

Databases for ES can be very complex and made by different vendors than is the ES software.

ES costs can be large and should be accounted for the entire system life. Intangible costs include organizational change and employee resistance to it.

ES improves process performance due to better coordination across the enterprise, elimination of complexity associated with separate departmental IS, time savings, more effective management control, and decision making using integrated view of enterprise.
