My presentation to SAP's UK #SAPForum in Birmingham on July 03 2013.

Synopsis:
Because data is what drives key business processes, to fully realise return on your SAP investment it's critical that the data you have is of high quality and validated to fully support your business processes. Although most data migrations focus almost exclusively on the technical build the 'X factor' for success lies in good Data Design. This session will explain how to select the optimal migration approach for your requirements, what Data Design actually involves and how collaborating with the business in Data Design will dramatically reduce project risks, timescales and costs.

  • SynopsisData Design: The X Factor for a Successful SAP MigrationThe biggest mistake most organisations make is to approach data migration as a tactical challenge, overlooking the fact that data is what drives their key business processes. Data Migration can be expensive, risky and difficult – yet in spite of well-known risks many businesses frequently do not fully understand the challenges until too late and problems become expensive to fix.  Sharing ‘real world client experiences this session discuss:Why good Data Design is critical to successful data migrationHow to engage the business to ensure the data you have is transformed into the data your business processes needHow to select the optimal approach for your specific data migration requirementsHow automated code generation dramatically reduces project risks, timescales and costsAlthough based on Clive’s extensive SAP experience there are lessons to be learned here for all enterprise scale data migrations.
  • Within the Data Migration area, again the reports provide validation and information to support the creation of the mapping specifications and value mapping processes, as well as tracking progress for the projects management team. The actual data flowing through the migration process is dynamically available within the Data Profiling, Rule Violation and Data Model reports.

  • 2. © 2011 ENTOTA LTD 33ENTOTA 2013© Data Migrations often get a bad press More than 80% of data migration projects run over time and/or over budget. Cost overruns average 30%. Time overruns average 41% Bloor

  • 4. © 2011 ENTOTA LTD 55ENTOTA 2013© Why do so many data migrations fail? Attitude to the data migration project • Tactical • One-off • Outsourced, 3rd parties Technical and Data issues • Source data quality and knowledge • Continuously changing target • Too many others to list here! Management issues • Lack of visibility into progress and status leads to nasty surprises • Politics, culture and deadlines Issues caused by spreadsheets and lack of collaboration

  • 16. © 2011 ENTOTA LTD 1717ENTOTA 2013© Data Designers should… Organise  Assign business process names  Assign business process owners  Create the data object inventory Define  For each data object • Define the data quality rules to setup the data quality ‘firewall’ • Business rules that define what is business valid • Active record determination and archiving rules Map  Centrally maintained mapping rules integrated with sample records  Structured approach to source-to-target mapping rules enables reusability
  • 17. © 2011 ENTOTA LTD 1818ENTOTA 2013© Data Design drives successful migrations Manage Inventory  Conversion inventory defines the scope of the migration  Ensures a centralised record of all the data related activities that need to take place at cutover Collect  Often need to provide data inputs when data not held within a source system  ENTOTA recommend a single place to collect user specified data rather than spreadsheets that have little control or governance Synchronise  Single place to manage everything ensures nothing is out of sync  Target system interrogated to ensure technical and business validity  Auto-generated code always based on the latest definitions
