Title: IEEM 5352 E-Enterprise Integration


1
IEEM 5352E-Enterprise Integration
  • Architectural Planning of
  • Intra-enterprise Integration

2
Lecture Objective
  • The objective of this lecture is to explain the
    major concepts of intra-enterprise integration,
    so that they may be extended (with understanding)
    to include inter-enterprise integration,

3
Enterprise Integration(Initial Definitions)
  • Enterprise Integration is the vertical and
    horizontal alignment of plans, business
    processes, and information systems across
    organizational and functional boundaries to
    provide competitive advantage.
  • The process of achieving Enterprise Integration
    includes all managerial and technological factors
    that enable cross-functional process integration.
  • The end result is a customer oriented management
    structure with information systems that are
    formally linked to processes and the integration
    of processes needed to establish/retain customer
    satisfaction.

4
Extended Enterprises
  • Customers
  • Suppliers
  • Partners
  • Contractors and Subcontractors
  • Temporary Partners
  • Others

5
Enterprise Integration(Refined Definitions)
  • Intra-Enterprise Integration applies to a single
    enterprise.
  • Inter-Enterprise Integration applies to the
    extended enterprise.
  • The extended enterprise includes suppliers,
    customers, partners, and other enterprise
    constituents.

How Does One Achieve Horizontal Integration?
10
Achieving AlignmentProcess vs. I.S.
  • Reengineer the process, and then develop an
    integrated information system that aligns with
    the business process.
  • Adopt an off-the-shelf standard software solution
    and reengineer internal business processes to
    align with the solution.
  • SAP, Baan, Oracle, etc.
  • Most US companies have selected the second option.

11
Relationship to IDE
  • The Integrated Data Environment (IDE) the most
    basic EI concept.
  • How does horizontal integration relate to IDE?

12
The Integrated Data Environment (IDE)
  • An IDE implies the electronic sharing of data in
    support of cross-functional process integration.
  • The data are stored once, but accessed as needed.
  • The organizations information systems are
    aligned with the workflow processes.

13
Intra-Enterprise IntegrationBusiness and
Technical DataThe Major Components areERP,
PDM/PLM, EDM, and MES
14
Intra-Enterprise Integration(Including Technical
Data)
Dataflows
15
ERPStandard Software Solutions
  • These are pre-engineered and integrated solutions
    that connect the complete scope of the business
    applications.
  • The solutions are usually modular e.g.,
  • Financial and Accounting
  • Human Resources,
  • Sales and Distribution,
  • Manufacturing and Logistics.
  • Full implementations are called Enterprise
    Resource Planning (ERP) Systems.

16
Product Information Management
  • PIM captures all design elements and all related
    information during the design process.
  • The focus is on the operational requirements at
    the interface between manufacturing and
    engineering design.
  • The primary focus is on document and
    configuration management.
  • The primary PIM components are Product Data
    Management (PDM), Product Lifecycle Management
    (PLM) and Enterprise Document Management (EDM).

17
Product Data Management
  • PDM is a combination of change and distributed
    electronic document management to support product
    development in manufacturing.
  • PDM emphasizes the managing of formal product
    structures hence, the concept favors discrete
    manufacturing.

18
Key Elements Associated with PDM
  • Configuration management ????
  • Data control and vaults ????
  • Archiving ??????
  • Access control and security ????
  • Release and approval ????
  • View and markup ???????
  • Engineering changes ????

19
Enterprise Document Management (EDM)
  • EDM systems permit an enterprise to create,
    index, store, query, retrieve, view, modify, and
    print documents.
  • EDM systems are made to be used across an entire
    company, while PDM systems are more toward
    applications specifically for the engineering
    departments of manufacturing and design
    corporations.
  • EDM systems primarily organize documents along
    the generic hierarchical folders and file them
    that is prevalent in graphical computer file
    systems.

20
Manufacturing Execution Systems
  • MES describes a species of plant-floor computer
    systems meant to automate production control and
    process management.
  • These standard software solutions replace both
    paper-based systems and the many stand-alone
    systems that have sprung up on plant floors over
    the last 25 years.

21
MES is and is not
  • MES does not have planning focus.
  • MES is concerned with scheduling work, based on
    orders that are in hand.
  • The MES provides realistic delivery dates to
    customers wanting to place orders, based on
    real-time information about shop floor
    conditions.
  • MES is the information system that tells plan
    floor resources (e.g., people, equipment, and
    controls) how to build and provides feedback on
    what was built and when.

22
The Dataflows
  • Data flowing from the ERP system to the MES
    include production demand, bill of materials,
    drawings, part programs, routing information, and
    process data.
  • Dataflow from the MES to the ERP system include
    real time resource status, labor status, actual
    bill of material, actual routing and process
    data, product genealogy as built, and scrap
    levels.

23
MES Dataflow in an Enterprise
24
MES Integration
  • In 1995 it was estimated that roughly 80 of MES
    installations operate with MRP II.
  • At that time, it was projected that there was a
    growing trend toward integrating MES with more
    comprehensive ERP systems i.e., integrating MES
    with order entry, financials, and distribution.
  • To a large extent, the projection was optimistic
    and remains unrealized, although progress has
    been made.

25
Component Supplier Management (CSM) Systems
  • CSM Systems provide a between engineering design
    and procurement execution.
  • This represents one link between engineering and
    business systems.
  • CSM systems are usually an add-on module to ERP
    systems.

26
The Components of a CSM System
  • A classification scheme that describes components
    according to physical characteristics.
  • A component reference database.
  • Tools and services for legacy data migration to
    the database.
  • A navigator and data mining capability for the
    database.

29
Intra-Enterprise Integration Status
  • Most large US firms have been striving to achieve
    parts of the previously presented model.
  • Some parts are more difficult to achieve than
    others, but in some areas, significant progress
    has been made e.g., CSM and procurement
    execution.

30
Inter-enterprise Integrationor
Business-to-business EC
  • Business-to-business EC extends the
    intra-enterprise integration model to include
    suppliers and customers.
  • The new model is one of inter-enterprise
    integration, with a focus on self service.
  • Our leading firms are extending the first round
    of integration activities to include the supply
    chain, and the Internet is the enabler.
