CSG’s ALM Approach
 Best in breed approach
• Mostly an evolution – no big bang
• Integrated what we had
• Upgrade to better components as we find them
 Solidifying around Atlassian Suite
• Not Open Source but customers are allowed to view and modify
source
• Integrates with many third party tools
• Web based
• Hosted or On Premise
• Rich plugin ecosystem/marketplace
• Open web-based APIs and SDKs

version
 Third party dependencies too!
 Don’t check binaries into Subversion
 Non .NET teams have same needs
 Eventually could replace CSGCopyDeps with NuGet

35. Copyright © 2013 CSG Systems International, Inc. and/or its affiliates (“CSG International”). All rights reserved.35
Artifactory - Package Repositories

 Directories are first class objects, just like files
 Branching and Tagging are “cheap”
• Copy on Write
 Widespread adoption & integration with other tools
 No Stash/Shelve features
• We utilize a Branch

39. Copyright © 2013 CSG Systems International, Inc. and/or its affiliates (“CSG International”). All rights reserved.39
Subversion - Source Control
 VisualSVN Server – On Premise Subversion installation
for Windows

 Builds latest from SVN
 Uses dependencies officially staged from Package
Repository
 Results are staged into Package Repository
 CREATE and MIGRATION scripts also generated
 Triggered nightly

51. Copyright © 2013 CSG Systems International, Inc. and/or its affiliates (“CSG International”). All rights reserved.51
Build Types – Continuous Stable
 “Current build”
 Builds latest from SVN
 Uses dependencies from Package Repository
(dependency DSMs)
 Runs extra checks such as Code Analysis
 Results are not staged into Package Repository
 Triggered off of SVN commit or dependency DSM

52. Copyright © 2013 CSG Systems International, Inc. and/or its affiliates (“CSG International”). All rights reserved.52

dependency
 Results are not staged into Package Repository

Build Types
Build Type Description
Daily Build (DSM) Builds the latest of a module's branch/trunk,
including database CREATE and MIGRATION
SCRIPTs, using other modules officially staged
assets as dependencies, results are officially
staged. Triggered Nightly.
Continuous Stable (CS) Builds the latest of that module's
branch/trunk, using other modules' officially
staged assets as dependencies, results are not
officially staged. Triggered by an SVN change.
Continuous Integration (CI) Builds module's trunk and uses the artifacts of
the latest successful CI build for each
consumed module. Triggered by an SVN
change. Causes all down stream modules' CI
builds to run.
Smoke Tests Owned by module teams. Takes built artifacts
from CS build and runs entire test suite.

Build Types
Build Type Description
Continuous Stable Database
(CSDB)
Builds CREATE and MIGRATION script based
off the latest of that modules branch/trunk
Database Restore Utilities
(QRDB/PRDB)
Stands up a Production/QA database backup
to a database server. Triggered by forcing the
build and selecting various parameters.
Documentation (DOC) Runs like a DSM except it does not publish
built artifacts. Builds documentation using
Sandcastle and publishes the documentation
as defined in the various projects.
Sonar (SONAR) A suite of tests are run under the SONAR
framework and results are published for
subsequent analysis. Triggered on a nightly
schedule but can also be forced.
