Configuration management
Configuration Management

  • ANSI/EIA-649

    • "A management process for establishing and maintaining consistency of a product's performance, functional and physical attributes with its requirements, design and operational information throughout its life."(http://www.pdmic.com/cmic/introtoCM.shtml)

  • Susan Dart

    • "The goals of using CM are to ensure the integrity of a product and to make its evolution more manageable.”(http://www.loria.fr/~molli/cm-index.html)

Apt development challenges
APT Development Challenges

  • Code Integrity (Design, Implementation)

  • Multiple Developers (Implementation)

  • Build Availability (build, testing)

  • Release Requirements (release)

Main strengths and weaknesses
Main Strengths and Weaknesses

  • The latest develop version is always available.

  • Code for each release is isolated.

  • We are very robust to supporting multiple platforms.

  • We don’t have a good way to safely manage long term projects (> 2 months).
