Software Configuration Management

Lecture: SCM and PDM

Niels Veerman

René Krikhaar


Lecture objectives l.jpg

Lecture Objectives

  • Learn about Product Data Management (PDM)

  • Learn about SCM/PDM similarities and differences

  • Learn about SCM/PDM tool integration


A definition of pdm l.jpg

A Definition of PDM

  • Product Data Management is the discipline of designing and controlling the evolution of a product design

  • PDM systems and methods provide a structure in which all types of information used to define, manufacture and support products are stored, managed and controlled.

  • PDM supports Hardware Configuration Management


Product data management l.jpg

Product Data Management

Typically, PDM is used to work with electronic documents, digital files and database records, including:

  • product configurations/structures

  • part definitions and other design data

  • CAD drawings

  • geometric models

  • images (scanned drawings, photographs, etc.)

  • engineering analysis models and results

  • manufacturing process plans and routings

  • software components of products

  • audio and live video annotations

  • hardcopy (paper-based and microform) documents (by reference)

  • project plans, notes and correspondence

  • others


Pdm main functions l.jpg

PDM – main functions

User functions

  • Data Vault and Document Management (storage,meta-data & routines)

  • Workflow and Process Management (process monitoring & control)

  • Product Structure Management (part hierarchy & relations management)

  • Part and Component Management (classification & retrieval)

  • Project Management (project monitoring & control)

    Utility functions

  • Data Transport and Translation

  • Image Services (displaying data)

  • Administration (user access control)

Software/hardware worlds

Hardware process

  • SW and HW development processes differ

    • Incremental vs sequential

    • Concurrent development

    • Manufacturing phase (hours vs months)

  • SW and HW cultures differ

    • Terminology and tools

    • Single-domain knowledge

    • Product focus

Software process

Hardware focus: documents

Software focus: source code


Scm and pdm tool integration l.jpg

SCM and PDM tool integration

  • Why?

  • When?

  • How?

    • No integration

      • Manual intervention

      • Risk of inconsistencies

    • Loose integration

    • Full integration

SCM/PDM – loose integration

  • Independent tool operation

  • Own information models and repositories

  • Information exchange

    through interoperability functions

  • No common information model

  • Integration points

  • Periodic synchronization required

  • Interoperability functions

    can become very complex

Summary l.jpg

Summary

SCM and PDM integration =

an efficient way of managing product information

  • SCM – managing software product data both processes and tools originates from software development

  • PDM – managing product data both processes and tools originates from hardware development


Conclusions l.jpg

Conclusions

  • Overlapping in tools, technologies and processes

  • Used by different domains with different cultures

  • In order to build an integration, the following has to be considered:

    – Processes

    – Tools and technologies

    – Culture differences

  • Many SCM/PDM challenges ahead!
