Product

A Product is a set of bits, e.g. an ISO image or a self extracting exe.

A product may be described by

• the source code to be used (e.g. a CVS repository and a CVS tag), this is the products code base,
• it's features, as well as the brand and the localization to be included, and the configuration used while building, this is the products variant,
• it's relationship to previous products, this may be something as "patch", "update", "respin" or "add-on", this is the products type,
• the format of its bits, e.g. "ISO image", "self extracting archive" or "APT repository", this is the products format.
• the target platform (architecture and Operating System), e.g. Solaris Sparc, Linux x86 or Windows x64, this is the products platform.

E.g.

SO8u9Solx86-CD = SRC680_m236, [{StarOffice}, {Writer, Calc, Impress, Draw}, {English, German}], Update-to(SO8u1), ISO, Solaris/x86

Version

Software provided to a customer typically has a version, describing timely variant. Typically older variants have smaller version the younger variants. Versions may be differentiated into Major, Minor and Micro.

Relationship

• No relationship -> self contained
• Update relationship
  • update only (e.g. add-ons, localizations)
  • self contained (e.g. OOo 2.1 updating OOo 2)
  • Multi-update relationship
    • Cross version (major / minor / micro)
    • Cross language
    • Cross brand
    • Cross variant
    • Cross platform

Requirements

Development

Support for Changes:

• updated package(s)
• (automatically) remove package(s)
• add package(s)
• rename package(s)

• remove file(s)
• add file(s)

Program Management

In a perfect world, program management would be able to create any kind of product, only depending on business needs, not at all restricted by technical constraints.

Program Management basically mediates between marketing / market requirements and the pool available technologies.
