Project Challenges and Lesson learned
 Business Challenges
•
•
Verification of Bank files from major banks due to Unicode remediation
Treasury functionality change significantly from Ehp5 to Ehp7
 IT Challenges
•
•
•
Several Diverse teams on SAP side to interact and co-ordinate including
o HEC Team
o HEC services team (backend processes like, backup jobs, etc.)
o Migration Team (SAP Services)
o Business functions team (BI, Fiori, etc.)
o AMS
o Testing (SAP Services)
No central authority over all these teams
HEC activity is driven by ticketing process & difficult to get dedicated resources
o Create tickets well in advance to reduce time
o Difficult to get the same group of resource for Dev, quality & Production
o SLAs are different between Project build phase & go-live phase
 Infrastructure Challenges
•
•
Network Extension Challenges
o Manage and Maintain DNS across both networks
o Plan for FTP and SFTP requirements early
o Ensure accommodation for DR site in hostnames
Operating System
o Migrate from Windows to Linux
o File and folder permissions vary
o Cross mount NFS vs migrate
o Review file paths in job variants
Project Challenges and Lesson learned
 Infrastructure Challenges
• Server Certificates
o Load balancer & Web dispatcher signed certificates
 Technical Challenges
• Unicode Remediation
o Identify the programs used in last 365 days for critical path
• Personas
o Retrofitting Personas 2.0 takes good amount of work and a lot of notes to be applied
o Evaluate moving to Personas 3.0
• SAPGUI
o Upgrade to 7.4
o Ensure the SAPGUI updates to remote users
o Personal lists needed to be rebuilt after the upgrade
 Delek Project Team
• Small Team
• Long Hours
• Short Timeline
• QA Automation with TAO & Solution manager
 HEC knowledge – Know the big picture but not the details
