Current priorities
Ideal priorities
Challenges IT Executives always seem to face…
Create challenges to
Application Cost Control
Application Quality
Application Performance
Quality Challenged software: A hidden drag on IT
and business performance
Unnecessary
IT Cost
Drag on
Business Productivity
Faulty Application
Software
Sloppy Development:
Bring back contractors
to rework 40% of code
Poor Design:
Add hardware as
quick fix for perfor-
mance lapses
Inconclusive Testing:
Hire new QA vendor as last
resort before deployment
Delayed Launch:
Competition got there first
Frequent Brownouts:
Call center reps
waste time; average
wait times rise
Unpredictable Disruptions:
Customers move to other
online competitors

• Complex Development/Production environments
– Legacy / Objects / 100+1 languages and operating systems
– Insource / Outsource / Homegrown / third party
– Server / Web / co-located / Virtual / Cloud / SOA / Middleware / Software everywhere
• 24 x 7 Global operations: There is no tomorrow…
• Economic projections means…
– Slower growth and tighter IT budgets
– Competitive survival pressure increases (less food in the forest)
– Fear replaces reason in driving decisions
• Executive perception is reality…
– Anecdotal news (bad news travels faster than speed of light)
– Hard data often lacking to balance opinions
Challenges Software Development Leaders
Face Today
7
• Focus on getting more out of existing systems
• Fact-based justification for maintenance increases reduces executive blowback
• Fact-based data on quality supports confidence in the QA function
• Fact-based data on quality will suggest high-ROI initiatives on
– cost reduction
– productivity improvement
– software lifecycle changes
Opportunities Software Development
Leaders can move on today
…Facts require Intelligence
Application Intelligence
Security
Robustness
Performance
Transferability
Changeability
Effort Metrics Function Points
Work Effort Estimation
Maintainability Index
• You are entitled to your own definition of quality standards
• You are not entitled to your own set of facts
• Application Intelligence arms you with factual data to which to drive the right kind of change from the Executive suite to the test lab

Performance
Transferability
Changeability
Effort Metrics Function Points
Work Effort Estimation
Maintainability Index
Improved Quality Metrics Visibility
Measure quality that fits your culture and cost profile
Define/track Defects tracing root causes
Provide IT executive visibility to reduce unfounded
opinions
Higher IT Team Productivity
Catch quality problems earlier: multiple savings per
defect
Understand code quality to share best practices
across organization
Reduce application maintenance costs
Fix architectural problems once
Fix workmanship problems and improve team skills
Do more and quicker with your Applications budget
…Facts require Intelligence
Intelligence informed Product
