14
Download and Install

• Check Open Software Web Site (e.g., via
  SourceForge) for news/latest release info
• User download packaged open software source code
  files (e.g., RPMs) and/or executable image
• Unpack and and install source code

15
End-Use

• Review any application documentation or Web pages
• Use downloaded executable image
• Optional
• Perform local source code build
• Perform local integration test
• Perform local version control check-in

16
Communicate Experience

• Browse OSSD project Web site, discussion forum,
  or other online sources
• If observe bugs, then do bug report
• If observe performance bottlenecks, external
  innovation opportunities, or localization
  shortfalls, then do enhancement or code
  restructuring request

17
Analyze and Redesign

• Select application, process, or Web site to
  redesign
• Analyze and model
• Identify and Extract structural properties
• Components, connectors, interfaces, resources
  I/O, configuration, and version(s)
• Identify applicable redesign heuristics
• Develop redesign transformation plan
• Execute plan

18
Assert Requirements-Design

• Assert software requirements or design update
  using communication tools/artifacts
• Read and make sense of updates, determine
  accountability
• Browse and extend software discourse web
• Harden discourse web via navigational
  cross-linkage
• Provide global access to software web

19
Develop Open Source Code

• Check-out and download source code from project
  repository/Web site
• Edit source code file(s)
• Compile local source code into executable image
• Debug as needed
• Perform unit test on executable image
• Submit source code to configuration management

20
Manage Configuration (1)

• Compose/integrate source code files (e.g., via
  Make files)
• Build/make executable composed image
• Regression test executable image
• Optional
• Submit source code for review
• Review and approve/reject submitted source

21
Manage Configuration (2)

• Check-in source code into (CVS) repository
• Create remote installation package (e.g., RPM)
  for release
• Create and build multi-platform executable images
  for release
• Create release news information
• Post news and release on project Web site
• Track and record source/image downloads

22
OSS Community Development
OSS Community Development Process
23
Develop Community

• Contribute External Source Code
• Initiate OSSD Project
• Create OSSD Project Web Site Portal
• Create and post Project OSSD to do items
• Invite new contributors to join
• Create community rights of passage and
  hierarchy
• Assert relevant OSS license/rights to use
• Create Foundation to assure legal status

24
Contribute External Source Code

• Develop open source code implementation of
  existing software system/application
• Create Web site for open source code content and
  announce project
• Optional Register project and Web site at
  SourceForge, Freshmeat, or similar
• Configuration manage source code
• Solicit community participation in further
  developing open source

25
(Re)Organize Project Team

• Solicit and designate Project core contributors
• Identify opportunities for other contributors
• Identify secondary and tertiary participant roles
• Self-select Project to-do tasks to perform
• Self-select Project teamwork structures or
  patterns
• Align Project (local) configuration for tool,
  repository, and OSSD artifacts

26
Scan External Environment for Innovation
Opportunities

• Surf informative Web sites and other media for
  content on new tools, techniques, concepts, or
  data source that may add value to local OSSD
  project
• Acquire additional knowledge of these
  opportunities, as needed
• Propose new features or enhancements on local
  OSSD project mail list server for how and why to
  incorporate the opportunity

27
Develop Community Software

• Select OSSD Tools for use by Project
• Setup Project Web Site
• Setup Project resource repositories
• Network file servers
• CVS directory structure/archive
• Content management servers
• Post links to Project tools

28
