• General Performance issues in the Catalogue (Navigation, Attribute Values,
Stock Information, …), but also in calling ERP functions

• B2B shop scenario is the best starting scenario at the moment for getting
experience with SAP HANA (benefits for IT and Business)

Key Challenges and Success
Factors
TEC 237 – Günther Lanner
Key Challenges and Success Factors
Key challenges faced
Get familiar with HANA, as this was our first HANA implementation we had a lot of
things to learn do a start workshops, involve several SAP experts
Replication of data was also very challenging, to find the tradeoff between source
systems influence and an acceptable latency time
Information to all relevant stakeholders, as SAP HANA is a topic with max
attention from all areas (IT colleagues from application and infrastructure teams,
business, and also SAP) stakeholder analysis and communication plan, several
info presentations

Key Challenges and Success Factors
Key lessons learnt
What went well?
Objectives were achieved; less technical issues with HANA than expected; Especially
stability could now be achieved with HANA (live since 18 months – only one minor issue)
Project was managed professionally – information flow was sufficient;
Project Team was highly motivated and eager to work with HANA and achieve great results.
What could be improved?
Too many experts from SAP involved; (some were less experts than expected and some
only in a particular area). Next time better to have SAP consultants with a broader Know
How.
Significant PM efforts because of new technology and high management / stakeholder
(SAP) attention
Improvement is possible, also in areas we thought it was not possible (e.g. ABAP
performance improvement)

Key Challenges and Success Factors
Key contributors to the success of your project
Involve all stakeholders during the project
Detailed project planning and controlling
SCRUM as success factor for the developments/testing part of the project
Doing an assessment with SAP before project start which included:
Collect business requirements and calculate a business case
Define technical requirements by workshops with SAP and some customer reference visits

What did the quality award
change?
TEC 237 – Günther Lanner
What did the quality award change?
• Establish the PM approach for all further HANA projects, esp. the stakeholder
analysis and communication matrix
• Communication is now done in a better and more efficient way. Important because SAP HANA has a
very high attention in our company
• SAP AGS involvement is standard procedure now
• Further rollout of SCRUM
• More business awareness for HANA, potential for further HANA business projects
• Motivation of project team
• Further quality awards participation planned
• Project leader has now lots of followup projects to choose of ;-)
