Configuration Management is a Systems Engineering process for establishing and maintaining consistency across the LBNF/DUNE/Integration project's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The Systems Engineering Management Plan (SEMP) docdb 49 describes the Configuration Management (CM) responsibilities and processes that support the design and implementation of the Long-Baseline Neutrino Facility (LBNF), Deep Underground Neutrino Experiment (DUNE), and Integration project elements. The main goal of the LBNF/DUNE/Integration SEMP is to prevent unauthorized or uncontrolled changes to engineering design or analysis, hardware, controlled documents, and controlled software.
The SEMP provides the guidance necessary for Change Control and Interface Management and Requirements Management. Currently, Design Documents, Requirements, Interface Control Documents (ICDs), 3D models, interface and layout drawings and supporting documents for requirements are being placed under configuration management in EDMS. The documents that are currently under configuration management are available at the following EDMS locations:
Configuration control is implemented in EDMS utilizing workflow for the documents. The following image shows the steps involved in the EDMS configuration control process.
A document when initially posted in EDMS is assigned the “In Work" status. The owner of the document then places it under “Engineering Check" to solicit feedback from reviewers if needed. When the feedback comments are received the owner then updates the document and places it “Under Approval" workflow to solicit the approval of the document by the responsible personnel. The document is then “Released" which signifies that the document can no longer be modified. Any update to the document will then require the initiation of a “New Version".
The above described process is a brief overview of implementing config control in EDMS, there are other ways of setting up signoff for approvers also, which are not described here.
