Unit Lesson Just What is ERP?
To answer this question, it helps to look back and consider how companies managed
before enterprise resource planning (ERP). Companies consist of a number of
functions that each work together to earn a profit. These include the creation of a
product, (Research and Development (R&D), the production of a product
(manufacturing), locating clients and offering the product for sale (Sales and
Marketing), shipping the product (warehouse functions), and finally, taking money and
accounting for the sale (Finance and Accounting). Prior to the advent of computer
systems in business, each function carried out their respective jobs on paper, and kept
detailed records in journals, file folders, and filing systems. As the technology became
available, some of these paper functions became computerized in order to make them
more efficient. However, computerization did not solve the fundamental problem of the
paper organization—the difficulty of sharing data.
In a paper organization, accounting kept the books in accounting journals, sales and
marketing made notes of contacts in pocket planners and wrote paper reports—or
perhaps even sent and received faxes. R&D kept records in engineering notebooks,
and finally, the warehouse function kept files and records of incoming and outgoing
transactions. ERP was a response to the problem of the intra-organizational sharing of

data that previously resided in a function so that companies could become more
focused and competitive. However, ERP was not born in a day—rather, it started in
one function, and it evolved into what we have today.
In the Beginning, There was Transaction Processing…
Computers began to assert themselves within the business arena by easing the
burden of the tedium associated with recording of data. Where was the recording of
data the most intense? This was in the areas of shipping and receiving, accounting,
and material control. It is easy to see why recording data in these functions would be
time consuming. When a sale was made, the sale would need to be captured on an
order form. The order form would typically need to be transferred to an internal
inventory “pick-list” or, forms that would pull the associated parts and components
forming the “kit” that would fulfill the customer’s order. When the components were
pulled, inventory would need to be manually decremented by updating the warehouse
books. Accounting would then need to record the sale, increment accounts
receivables, and decrement inventory. Invoices would be issued to the customer, and
if necessary, orders for new components would be placed to suppliers. This is quite a
bit of work, so why not automate the sequence of events? For example, why not enter
an order, and have the sequence of internal events and paperwork generate
automatically? This where MRP arrived at the scene.
MRP, the Precursor to ERP
MRP, or “material requirements planning” is a manufacturing centric system that
manages the warehouse, production floor, and material management books, and links
all of these with the internal accounting system. The benefits of such systems were
obvious to high-volume manufacturing companies who previously had to live with
implementing the internal processes by hand and on paper. However, as MRP
became more widely used, it became obvious that manufacturing, material control,
and accounting were not the entire company—and other company functions had data
processing needs, and such data would benefit from being integrated with the MRP
system. For example, the management of products from out of R&D into
Manufacturing generated part numbers, bills of materials (BOM), and work
instructions. Sales and Marketing would collect data on customer requirements and
deliver such information to engineering. In short, volumes of detailed data must flow
through all functions of a company, and it therefore makes sense to enter the data
only once, and use it where applicable. This is the essence of the ERP concept.
ERP: Common Database, Multiple Systems
As we have seen, each functional area has its unique data needs, and as a result,
each function tends to have systems that are optimized for the particular function,
Sales and Marketing, for instance, focuses on the management of sales leads, bids,
quotes, and competitive information. The optimal system to manage these functions is
the Customer Relationship Management, or CRM system. The R&D function relies on
computer aided design or CAD systems along with department intranets, and software
development tools. The accounting department relies on specialized accounting
software that records and manages transactions and updates the balance sheet,
income statement, and cash flow ledger. The beauty of ERP is that each of these
optimized systems is maintained, but the data can be shared and retrieved from a
MBA 5401, Management Information Systems 3
single database. In this way, a holistic view of company operations can be developed,
and the company’s strategy may be optimized.
Now that we have ERP, What do we do with it?
ERP created the centralized database and allowed for the sharing of data collected
from the functional systems in the organization. But, just because you have data
doesn’t mean you can keep it or make sense of it. Data must be stored somewhere,
and tools are needed to sift through the data equivalent of “grains of sand on the
seashore”. This need drove the evolution of important managerial support systems.
For example, the need to store volumes of data led to the data warehouse—a large,
long-term repository of massive amounts of data. Since large volumes of data are not
easy to use, data mining systems were created to enable the “slicing and dicing” of
data so that the patterns in the data that are not immediately obvious to the unaided
researcher could be observed clearly.
Last but not Least-the Tools of the Data Trade
Important trends that impact a business may be subtle at first and difficult to observe
directly. Often these trends lie buried in data that a firm has already captured in the
course of doing business. The raw data may be collected, stored, and mined, but it
takes additional tools to transform the mined data into decisions and company
strategy. A DSS, or decision support system, can take many forms and can be as
simple as using Microsoft Excel or Access to sort and make calculations with data.
Ultimately a DSS is intended to provide support for managerial decisions. Significant
trends associated with the macro-environment inhabited by the company require more
sophisticated analysis, and this is supported by executive information systems, or the
EIS. Further developments in data analysis seem to arrive on the market daily, but
what they all have in common is that they attempt to uncover and highlight deeper
nuances in the data using algorithms of increasingly advanced sophistication.
Managerial support systems are in essence the capstone on the ERP pyramid, in
which they are designed to aid businesses in fully realizing what ERP set out to
accomplish.
