What is Configuration Specifications in Computer system validation?

 


In Earlier post we understood what is project validation plan (PVP) & What Content should include in PVP?


Now in this article we are going to understand What is Configuration Specification, Its Roles & Elements in Computer system Validation.

 

What is Configuration Specification (CS)?

The Configuration Specification details the configuration parameters & how these settings address the requirements in the URS. This may be a standalone document or detailed in the FS.

Configuration specification is specific & describes in detail how the function will be configured, and what you must do to test the function.

The configuration specification includes the configuration items for the application hardware and software, operating system, interface (if any) and data for the implementation of system.

The Configuration Specification document is defined in order to describe the list of HW/SW components included in the Computerized System.

Here you define the configuration of the application required for your business purposes based on your requirements (for example, Audit Trail Settings, Electronic Signature, User Administration, Authorization Concept).

Functional and configuration specifications are not required when using commercial off-the-shelf software (Category 3). As a result, the extent of the testing performed would also be reduced.

  System Configuration Specifications includes

•         Hardware Configuration

•         Operating System Configuration

•         Software Configuration

•         Interface Configuration

•         Data Configuration

 

The Configuration Specification identifies the System Configuration Baseline addressing the SW components and interfaces and the System Parameters, focusing on the configuration items which may affect the GMP functionalities.

A Security Matrix is created (included in the document or in a separated document) in order to identify the user profiles defined in the system and the related functions included.

The assignment of the users to each profile shall be executed according to the security-related procedures. The document shall also describe the IT landscape on which the software resides and how it is to be connected to any existing system or equipment.

Therefore the document shall include also (or make reference to other document) a description of the system landscape and a specification of all elements shown on the Landscape (e.g. Operating systems, Middleware, Ancillary Software e.g. PDF viewer, System environments, Interfaces, Relevant IT Infrastructure components e.g. Servers).

 

The CS describes how the system will be configured to match its functions to the business process. The actual configuration process usually occurs on-site after system installation, and may be performed by the system vendor.

The elements of the CS should now be recorded in the trace matrix beside the corresponding requirements and functions each configuration item is meant to satisfy.

What is System Release Certificate (SRC) in computer system validation?

Image
  In Earlier post we understood What is Validation Master Plan, Its content & Regulatory requirement in Computer system validation? Now in this article we are going to understand what is System Release Certificate (SRC) in computer system validation. System Release Certificate (SRC) is authorizes the release of System for use in the Production Environment at Location for the users in the department. The objectives of this SRC are to certify that System has been successfully validated and can be used by the users in the department at Location. It is essential because it confirms that all project/system has been completed as per regulatory standard mentioned in project plan.   This certificate provides confirmation that all activities specified in the validation plan have been completed & all acceptance criteria have been met and the software is ready for deployment. All system-related documents/procedures will be provided, developed and/or will be revised be...

What is RTM & Its importance in CSV?

Image
  In Earlier post we understood What is Configuration Specification, Its Roles & Elements in Computer system Validation. Now in this article we are going to understand What is Traceability Matrix, Its Use, & Benefits    in Computer system Validation.   What is Traceability Matrix? (TM) A TM is a document that co-relates any two-baseline documents that require a many-to-many relationship to check the completeness of the relationship. It is used to track the requirements and to check the current project requirements are met. What is RTM? RTM is a method used to establish the relationship between documents. Its purpose is to ensure that requirements have not only been traced to the appropriate design elements but also that requirements have been met through test or other means of verification. The traceability matrix is a tool both for the validation team, to ensure that requirements are not lost during the validation project, and for auditors, t...

GxP Assessment & Categorization of Computerized System

Image
The first stage of whether a system requires a validation is to identify whether the system has a GxP impact. The result of the GxP Assessment and system Category checklist decided whether Validation required for computerized system. If Outcome is “GxP Applicable” then follow Computer system validation procedure and other risk assessment for validating the system. All systems which handle data or processes which fall under the impact of GxP or any other regulatory requirements must be validated Determine whether the application has been validated elsewhere you in organization. The amount of work required may be significantly reduced by referring some of the deliverables in as in state or with slight changes. The details must be addressed in the change control. If required any “Non GxP Applicable “systems that process data critical to operations of the business such as those involving financial, certain personal data etc. Quality assurance, IT, CSV responsibility person, HOD of ...
