Product Lifecycle Management By Srinivasan V Mudaliar November 26, 2012
What is a Product?To understand PLM, you need to first understand definition of Productand the challenges associated with getting one to the market place.A good, idea, method, information, object or service created as a result ofa process and serves a need or satisfies a want. It has combinationof tangible and intangible attributes (benefits, features, functions, uses)that seller offers a buyer for purchase. @ http://www.businessdictionary.comExamples of Products:-
What is PLM ?PLM is a tool that helps to manage both product data and productdevelopment process.PLM Softwares vision is to enable a world where organizations and theirpartners collaborate through global innovation networks to deliver world-class products and services, allowing them to deal swiftly with emergingrisks and opportunities.PLM integrates and manage processes, applications, and informationthat define products across multiple systems and media.Any organizations in a global market place strives: To reduce Product costs To attain better Quality To reduce/improve “time-to-market” To attain Product Differentiation

Why PLM? In Industries the Most Common Problems are -• Ensuring everyone works to the correct revision level• Distribution of drawings• Time to implement an engineering change• Time to access drawings• Control of variants/configurations• Exchange of drawings with suppliers/customers• Revising paper based drawings Only 20% of Design Data is Geometry though the other 80% applies to it
Business Benefits of PLM• To help win more business• To build, store and share valuable information• To control the explosion of digital information• Provides data control and integrity• Aid in concurrent engineering• Speed up product development• Enable a virtual product development team• Provide accountability
PDM FunctionsIMAN User Functions: Data Vault and Document Management Workflow and Process Management Product Structure Management Classification Utility Functions : Communication and Notification Image Services Data Access Control
Data Vault and Document ManagementIMAN The vault is a data store that contains some data within itself and controls other externally generated data by managing access to it. It is used for logical grouping of the data. Types of Data stored in Vault - Product data e.q. Cad Model Files, CAE Data, Operating Manuals etc. Data about PDM controlled information.
Data Vault and Document Management Secure and Control Storage Check-in and Check-out provide information Access Release Management ensures data Consistency All the history is stored for future reference Non-electronic data can be managed The user need not know where data are stored
Workflow and Process Management The business processes in the organization can bemapped into PDM system using workflow (Life cycles). Business process rules/constraints can be incorporatedinto the Life Cycles.

Workflow Benefits Managed Electronic Review and Approval Saves Time through Automatic Routing Prioritizes Tasks Provides Management Reports Identifies Bottlenecks Drives the Business Pro-actively
Change Management The Institute of Configuration Management defines CMII as configuration management integrated with project management and quality assurance.Change Items: Change items are the objects, these correspond to documents and other components used in CMII model. Problem Report - Defines a problem or an enhancement. Change Request - Initiates a proposal that recommends a change and captures business decisions associated with the change. Change Notice - Change notice provides a detailed work plan to resolve a set of requests.
Change Management – Change Items A single change notice may logically group and addressissues identified in multiple change requests. A single change request in turn responsible for multiple problem reports.

Product Structure ManagementIt facilitates the creation and management of the ProductConfigurations and Bill of Materials.PDM system tracks the version, effectivity and Design Variationsof the Product Configurations. As Different disciplines requires the unique views of theproduct information, PDM system can show the different views ofthe product. e.q. Design View, Manufacturing view, Finance View Data can be transferred to ERP and SCM packages eq. BOM
Product Structure Management Consistency problems: • Several Output Formatsfrom July 1, 96 0815 /A • Different kinds of views (BOM types)until Oct. 17, 96 Car • Generic Configuration from Oct. 17, 96 • Variant Structure 0900 /A 0816 /A 0817 /B 0818 /A Chassis Chassis Engine Gearing new 0819 /A 0820 /C 0821 /A Bearing Toothing Case Box 0822 /A 0823 /B Upper Lower Case side Case side
ClassificationClassification of parts allows similar and standard parts, processesand other design information to be grouped by common attributesand retrieved for use in products.Benefits Similar parts and designs are found very easily. Part Family hierarchies provide organized access to existingdesigns.
Communication and NotificationIt involves the automatic notification of the critical events.Also the event itself triggers the notification. In some cases it actsas the security feature.E.q. Design is approved, The particular product is released
Image Services Images are stored and accessed like any other data Viewing and markup provide enhanced checking Image services enhance productivity of Engineering ChangeRequests.
Data Access Control Mainly for SecurityInvolves: Mapping of the business rules into the PDM system.

Technologies involved in PLM Database - Oracle, Sybase, Informix, SQL Server etc. Front end - X-windows, MS-windows etc, Web Browsers. Networked system enabling communication between hosts i.e.Unix systems, Windows-NT, Apple MacOS, Sun Solaris etc. Most of the PLM softwares are moving towards using J2EEweb technologies to allow easy of configuration and maintenance
