Traditional Production Model

• Traditional BTS Build to Stock
• Sales forecast ? production plan ? procurement ?
  production ? FG warehousing ? order taking ?
  delivery
• Slow movement of goods, capital tied up
• Traditional BTO Build to Order
• Customer order ? production scheduling ?
  procurement ? production ? delivery
• Long delivery cycle, lack of competitiveness

8
Exploiting IT capabilities

• Speed
• Accessibility
• Visibility
• Opportunities
• Early involvement and early availability of
  information
• Postponement of decisions

9
Current Production Models

• BTF/VMI Build to Forecast
• Customer rolling forecast ? procurement ?
  production scheduling ? production ? customer
  delivery notice ? delivery to VMI
• BTO
• Customer rolling forecast ? procurement ?
  customer order ? production scheduling ?
  production ? delivery
• CTO/ATO Configure to order, Assemble to order
• Customer rolling forecast ? procurement ?
  production scheduling ? production of components
  ? customer order ? final assembly ? delivery

Interchange of information

• Data
• Data files, coding
• Need Data interchange standards
• Message

• Need Message interchange standards
• Process
• The process involved in a single activity
• Process integration

20

• EOI- EDI over Internet
• HTML
• XML

21
Markup Language

• Markup is a method of conveying metadata (that

XML advantages

• Open, platform-independent
• Vocabulary Definitions of TAGS for different
  Application Domain
• An XML vocabulary is a description of XML data
  that is used as the medium for information
  exchange, often within a specific domain of human
  activity(business, chemistry, law, music, for
  example)
• Program Readable
• Note XML is not a programming language, nor an
  object-based system, nor an operating system. It
  is a powerful, elegant technique for thinking
  about, exchanging, and presenting data in a
  platform-independent manner.

25
XML and Browser

• XML changes in internal structure of browsers
• HTML Interpreter ? XML Parser
• A normal Hypertext web-page becomes Application
  page
• Application Software ? Browser Software
• XML XML data can be processed by application
  systems, instead of a browser

• Understand what the PIP number represents.
• A PIP number has 3 parts  a number a letter
  another number.  Example 3A4
• The first number represents the Cluster.   PIP
  3A4 is in Cluster 3.
• The letter represents the Segment.  PIP 3A4 is in
  Segment A of Cluster 3.
• The second number is a sequential number which
  completes the PIP number.  PIP 3A4 is the 4th PIP
  in Segment A of Cluster 3.
