Tool Overview
Atlassian Software Systems (Sydney, Australia)
• Jira and essential plugins
• Confluence
• FishEye
• Crucible
Perforce Software (Alameda, CA)
• Perforce Versioning Engine
4
• Project/issue tracker with powerful customization
options
• Agile plugin adds agile project management to any
JIRA project for software development teams
practicing Scrum or Kanban
• Structure plugin is an enterprise issue organizer
for Project Management, Requirements
Management, Test/QA and Help Desk
5
Enterprise wiki to collaborate and share knowledge.
Content variations
• IT helpdesk information
• Development requirements definition
• Development design/specification collaboration
• Beta tracking
• Deployment tracking
• Operations maintenance/logging
• Blogging
• Reporting
6
• One tool with two distinct purposes
• Fisheye provides the ability to view the
contents of your Source Code Management
(SCM) repositories in your web browser
• Crucible allows an on-premises code review
solution for enterprise teams
7
Perforce Versioning Engine stores and manages access
to versioned files, tracks user operations and records all
activity in a centralized database.
• Software version control
• Document management
• Release archive of record for production software
• Product delivery mechanism

Deployment Footprint

Lifecycle Processes Enforced by Tools
Jira
• Issue type specific workflows (Field Report, QA reported bug, Development
Epic/Story or Task, etc.) to define scope
• Auto assignment based on issue type to expedite closure
• Individual project team custom workflows to reinforce policies
• Custom fields (~200) and custom screens that require the entry of detailed
information to facilitate development efforts
• Agile development enforced by Jira Agile plugin to clearly establish formal
lightweight process
11
Lifecycle Processes Enforced by Tools
Jira
• Action authorization for issues managed by custom permission schemes
per project (role based for transition between workflow steps)
• Custom email notification schemes per project manages to whom email
is sent and for which event type (issue created, issue closed, etc.) to
eliminate noise
Perforce
• Protection scheme to prevent unauthorized or inadvertent access to files
• Policies in place to enforce intelligent branching
• Software products submitted and a promotion model established (Dev
Test – QA/Test – Beta – General Availability) for release management
• Product release documentation promotion model in place to ensure the
correct documents are bundled with each release
• Field Support team members pull the software release product from the
General Availability location to ready for deployment activities to
customers

What are the Benefits
Flesh out new features before development starts,
saving resource time by using the collaborative
design and requirements gathering in Confluence.
13
What are the Benefits
More maintainable code and improved products by
embracing efficient lightweight peer code reviews
with Fisheye/Crucible.
14
What are the Benefits
Early detection of bugs/issues prior to field
deployment by employing interative development
and test using Jira.
15
What are the Benefits
Better estimating of resource time, cost and scope
by using the Jira Agile plugin to manage competing
project priorities.
16
What are the Benefits
Project scope can span multiple Jira projects. The Jira
Structure plugin (also known as the Enterprise Issue
Organizer) provides a common view of overall progress
across projects with unlimited hierarchy (sub-issues,
sub-sub-issues, etc.).
17
What are the Benefits
Fewer customer outages for upgrades with new
software delivery model that ensures the qualified
software work product is what is deployed to the field
from Perforce (repeatable and reliable delivery).
18
What are the Benefits
The ability to accurately detail what was delivered
in a release with reports from Jira and Perforce.
19
Conclusion
The migration to this process started in 2003 and
was fully realized when our engineering teams
instituted the Atlassian tool set a few years ago.
