A New Paradigm toManage Technical Debt

▪De facto leader for code quality

▪Open source model

▪75K+ companies use our products

▪700+ paying customers

▪49 Fortune 100

SonarSource

▪SonarQube• Enterprise approach• 150K+ downloads/year• 70% of Java Dev use it daily

▪SonarLint• Developer centric• In the IDE

Products

20+ Languages

▪Too late

▪Pushback from teams

▪Lack of ownership

▪Heterogeneous requirements

▪Quality gate

Challenges

▪Development team owns quality

▪Shorter feedback loop

▪Unified quality gate

▪Cost is non-significant

▪This is fun!

Changing the Game

Fix the Leak!

How We Got Here

How many lines of COBOL code do you have?

18

Frustration of Not Knowing

Where to Begin• Who knows?• Who to ask?

Manager Developer Ops Vendor

• How long will it take?• Are the numbers right?

19

Domain Nomenclature

How do you decode these names?

Program/File Lines of code? Issues? Duplication?

POL12345.CBL ? ? ?POL12346.CBL ? ? ?POL12347.CBL ? ? ?COR12345.CBL ? ? ?COR12346.CBL ? ? ?

How Did I Proceed?Brought the right stuff to the table

Inspects my code, Java and COBOL

Made my COBOL tools more awesome

Gets my code, Java, COBOL and more

Benefits1. Less likely to deploy software defects

2. Team standards

3. Less duplication of code

4. Incredible visibility

5. Code reviews are much easier but not replaced

30

Cultural Changes

Good1. Team-wide acceptance now; they like itBad2. Very difficult for mainframe team to pick up distributed tools3. Senior COBOL developers could not independently spin up toolsTruth4. Java team had to spin up tools and mentor COBOL team5. Mentorship created incredible working relationship between teams

The GOOD, BAD, and The TRUTH
