SAP HANA@SiemensScope and objectiveProject ScopeProject ObjectiveMigration and consolidation of more than 50 SAPlandscapes to latest and standardized SAP release(e.g. ERP ECC 6 EHP7/Unicode) and SAP HANA forusers in more than 50 countries. Reduction of hardware and data center operationscosts with cost effective state of the art infrastructureThe project covered ERP, BW, SRM, HR and APOprocesses. Huge acceleration of transactions and reports,productivity increase for usersImplementation Partner is Atos IT Solutions and ServicesGmbH.PM@Siemens the Siemens standard projectmanagement methodology with standardized projectplans and milestones for all projects was used integratingAtos Standard MSP/PMP methodology.

SAP HANA@SiemensQuality Approach and TCOQuality ApproachRapid Time to Value and TCI/TCO Strict Program Governance: Siemens CIO, Heads of ITGovernance and Centers of Expertise for Divisions,Regions and Infrastructure were involved throughregular steering committees once per month.Program organization wasn't changed duringprogram timeline More than 50 projects running in one program withsame methodology in predefined timeframe Provider created reference architecture for onesystem which was adapted to all other systems Industrialized approach for system migration andcode remediation saved time and costs DMO as standard software was used for best practicedelivery Nearshoring of data center migrations helped toreduce costs at provider To ensure timely completion of code remediation anAtos program was developed and used for legacyABAP-code to identify all potential select statementsfor sorting issues as early as possible. Cost avoidance by combining other data centerchanges with the SAP HANA program Siemens specific HANA trainings for key expertsbefore project starts. Trainings have been organizedcentrally by Siemens training provider. Bundling for optimized infrastructure Bundling for cost effective ABAP remediationcontracts Consolidation of hosting locations to reduceoperations costs
SAP HANA@SiemensChallenges, Lessons learned and Key contributorsKey Challenges faced, Key lessons learnedKey contributors to the success To run migration in one weekend (especiallythe larger systems) Several test migrations of DMO and SNPtook place with learning curve and improvedmigration times on each test migration Code remediation for 28 projectsconducted with successfulindustrialized Offshore approach Tight program schedule: More than 50migrations in 18 months within midmonthtime slots Put enough migration resources intoprojects. Implement the rule of not morethan 5 migrations in one weekend throughsynchronizing of project plans andrescheduling if necessary. Adherence to data privacy and ISEC rules andregulations in the Offshore approach Involvement of legal and ISEC department Bundling of more than 50 singleprojects to one program withcentral program organization andstandardized industrialized approachincluding milestones and qualitygates for all projects. Identify similartasks for the whole program whichwere used as basis for a Request forProposal process to externalsuppliers Strong management support inconflict resolution and decisionmaking
