8. IT Business Needs
• CITGO needed a solution to validate critical business processes in
order to avoid business disruption and improve quality when
deploying SAP software updates and technology changes.
• The automation platform had to be user friendly for business
analysts.
8

9. Drivers for Automation
Worksoft Certify® was selected to:
• Quickly build and maintain complex end-to-
end tests in CITGO’s environments
• Mitigate risk due to technology change
• Improve the quality of testing; reduce
production defects
• Maintain the integrity of existing systems
• Reduce testing cycles, resulting in faster
SAP upgrade projects
• Increase the level of formal testing on other
projects and support
• Deliver significant savings and efficiency in
business process validation
9

10. Approach
• Organizational and Team Structure Established
– Four governance group members
– Nine sub-committee members:
• Including two Worksoft Certify administrators for attribute updates, role
administration, monitoring and coordination of upgrades to Worksoft platform
• Governance Effort
Naming Standards: Establish standard variable naming conventions. For
example:
• Main Automated SAP Scenario for Transaction Code
• Automated SAP Scenario with child process
• Manual SAP Scenario
• Main Automated SAP Scenario for Integrated Processes
• Automated HR Scenario
• Non-SAP Automated Scenario (MarketNet)
10

11. Approach
• Governance Effort (continued)
Required Fields
• Differentiate process attributes
• Review and approve test scenarios
• Develop reporting criteria
• Train members on the Worksoft Certify software
• Recommend process improvements
Promote to Production
• Before moving to production folder, team leads will make sure all naming
conventions and required information are within the scenario
Folder Structures
• Two main folders to manage activity
– Citgo Development: Development sandbox for all test scenarios
– Citgo Production: Master file for all test scenarios, whether single
transaction or integrated

13. Results
Business Process Coverage
• CITGO is using Worksoft Certify to automate the functional testing
of processes that support key areas in sales, purchasing, supply
chain, inventory and more
• 45%-50% of tests to support highly critical business processes
have been completed
• 769 of 1,910 business process scenarios covered in just 8 weeks
Greater Frequency in Quality Assurance & Defect Identification
• Previous testing was conducted only once per year; Worksoft
Certify is now used on a week-to-week basis
• Weekly testing supports day-to-day activities including
customization of reports, programming, running transactions,
problem solving, and more
13

14. Results (continued)
Efficiency and Time Savings
• Testing time is reduced from weeks to days, hours to minutes
• CITGO spends 3 months out of the year testing for yearly releases
• The company is on track to cut testing effort by 25% or more
with automation - replacing manual labor with digital labor
• Automation gives analysts time back – to focus on more strategic
projects.
• Initial project requires effort above the manual approach, but well
worth the time and investment
• Benefits will extend to subsequent projects

15. Results (continued)
Efficiency and Time Savings – by Workstream
Lubricant and Hydrocarbon process groups:
• Goal is to automate 85% of 1,060 test scenarios, reducing the number of
analysts needed to test and accuracy of testing
• Currently, 14 IT Analyst run full set of tests for 3 iterations of testing cycle
each year for SAP upgrade
• An 85 step business process was completed in less than a minute
• A 400 step business process was completed within two minutes
• Initial results: CITGO has converted 10-15% of test scenarios and
subsequently removed approx. 2 FTE weeks of testing through
efficiencies afforded by Worksoft Certify’s ability to link scenarios
• Worksoft Certify is being used for day-to-day program testing for “run the
business” activities
15

16. Results (continued)
Non-Hydrocarbon process group:
• Goal was to automate 60-70% of 850 test scenarios into approx. 50
Worksoft work process tests resulting in 3 FTE weeks of testing
• Approx. 10 full time equivalent (FTE) weeks of testing per each 850 test
iterative cycle
• Initial results: CITGO has converted 15-20% of test scenarios and
subsequently removed approx. 3 FTE weeks of testing through
efficiencies afforded by Worksoft Certify
• In addition to automation, Certify allows CITGO to test more wisely, spend
more time on critical process oversight and SAP updates
• End result: more thorough testing for the allotted time given to each
test cycle
16

17. Next Steps
• Further automation of business scenarios not covered during initial
project
• “Knitting” together CITGO unit tests to create additional end-to-end
business process tests
• Expanding use of automation beyond SAP
