Why to Manage Product Data?
Large volume of data
Data is on different media
Data is used by many people for different functions maybe at different sites
Data is used by many computer programs
Data exists in many different versions
Data has multiple relationships
Data may need to be maintained for many years

Product Structure Management
Product structure management facilitates the creation and
management of product configuration and Bill of Materials
(BOM)
Typically Product Structure (PS) contains attributes, instance
and location information of an assembly in addition to standard
BOM data
Standard BOM can be generated from Product Structure
automatically
Product Structure and parts can be associated with product
definition data like drawings, documents and process plans

Revision Control Deals with the modification of already released data / document.
Modification is not allowed on a released file. PDM vault maintains multiple revisions of same data.
To use the released data as the basis for new work PDM will copy
the file and places it in.
next revision code in the sequence. the initial status code in the status level of life cycle
Revise a document
After the document is released

Baseline
Baseline is a snapshot of the Data at a particular
instance of time
Baselines are created at important stages of the
product life cycle
PDM allows users to retrieve a particular product
configuration by baseline query

Work Management
Data undergo changes continuously
Work Management is what happens to data when
someone works on it A mechanism to capture all the changes to data
without affecting the original data
Ability to roll back the changes

Check Out and Check InCheck out
For doing any modification on the PDM controlleddocument, user must check out the file from PDM
The user must have sufficient privilege to Check out the
document at the current state
When checked out, the particular document is locked for allother users for modification
Others can have read only access
Check In
Once the user completes the modification, the file can beChecked in back to EDM.
This action will release the lock for other users
Ownership of the checked in file changes from user to vault

Workflow Management Data flows around in the department depending on the
development technique and lifecycle
Work flow management is flow of data between people
Dependency between data is complex and change in one data
may have a far reaching effect on others
A triggering mechanism controls the progress of the work along
with a routing list Many people participate in chiseling a Part
Sequentially and concurrently How work flows between people involved
Sequential, Automatic, Conditional
Reviews (electronic voting) Who can do what
User access control Notification Warnings

Lifecycle Lifecycle represents different states the product goes
through from concept to becoming obsolete
Lifecycle will have many states
Each state in lifecycle will have a associated workflow.
Change in lifecycle state will usually involve a review
process

Concurrent Engineering
Concurrent Engineering is a systematic approach tothe concurrent design of products and their related
processes, including manufacture and support
The objective of Concurrent Engineering, is to
command all the stages of the product developmentprocess simultaneously and to concentrate onshortening the development process and reducingdevelopment costs.
The idea is also to preserve the high quality of
production by constantly developing themanufacturing process

The idea of CE is very design and designer oriented. The
design, production, and marketing of products havetraditionally been carried out consecutively as a series ofrepeated functions.
The product goes through the different stages of designconsecutively;
the product designs are moved to production planning,which designs the production and the necessarymanufacturing software for the manufacturing process.
The procurement organization can then carry out materialacquisitions and production can begin on the actual product.
According to the principles of CE the whole process ought tobe carried out simultaneously in order to achieve the bestresult overall.
The idea is to make the totality efficient rather than torationalize individual sub processes
