Application Maintenance & Support

Sistema Technologies is well versed in Application Maintenance and Support.  The DIR DBITS contract defines “Application Maintenance & Support” as follows:

Definition: Application Maintenance and Support includes the skills and requirements for supporting application systems, including troubleshooting, modifying, maintaining and enhancing legacy systems.  Application Maintenance and Support also applies to applications running in a production environment.

Examples of included services: research, analysis, design, programming, testing, documenting and implementing maintenance changes; correcting software errors; modifying reports and ensuring accurate report runs; making modifications to the applications and documentation; writing ad hoc queries; loading and applying changes to the software language and/or database in which the application is written; providing corrections for production or any changes needed and participation in disaster recovery testing, planning and documentation.  Services may need to be available 24/7 or on an on-call basis.

Case Study:

Tesoro Energy Corporation is a large San Antonio-based energy company that uses SAP on a very large scale.  Owing to Sistema’s performance on the FSCM Migration and other SAP projects, Sistema was awarded a maintenance contract for implementing enhancements, change requests, and bug fixes for a period of 12 months.

Sistema Technologies was responsible for providing maintenance support to the SAP systems.  The support included fixing known defects, making code changes and testing any new functionality that was approved for maintenance work.  In addition, we identified opportunities for optimizing performance for all components being modified as a part of the approved change requests.  A large number of the change requests were in the HCM and PP Modules, including enhancement requests for the FSCM Module.

Sistema was subcontracted by Y&L Consulting, Inc. to perform 100% of the maintenance work.  Sistema’s performance on this maintenance contract was appreciated by the end client, and Sistema Technologies continues to receive more SAP work from Tesoro and other Y&L Consulting sub-contracts.
