Pharma IT Press publication  \nA Pragmatic Approach to the Validation of Excel Spreadsheets – Overview  \nMany GxP critical spreadsheets need to undergo validation to ensure that the data they generate is accurate and secure. This paper describes a pragmatic approach to the validation of Excel spreadsheets using the principals of GAMP 4. The validation lifecycle requirements are met using a generic documentation set which allows spreadsheet validation and implementation with two documented deliverables. Compliance with the user’s applicable regulations is achievable using this flexible and cost effective process.  \nBy David A Howard & David Harrison  \nKey Words: Validation, Compliance, Spreadsheets, MS Excel, 21 CFR Part 11, Pharmaceutical, GAMP, GxP, GLP, GMP, GCP, End User Computing.  \nEXCEL SPREADSHEETS  \nIntroduction  \nThis is the first of a series of short articles describing a generic process, as developed by ABB Engineering Services, for validating Excel Spreadsheets; future articles in this series will include the following topics:  \n• A Pragmatic Approach to the Development and Specification of Excel Spreadsheets  \n• A Pragmatic Approach to the Testing of Excel Spreadsheets  \nIt is recognised that Excel Spreadsheets have been widely used in all industries for many years. A major attraction of spreadsheets is their ease of use and flexibility – anybody with a minimum amount of training/experience can create and modify spreadsheets. The downside of this versatility is the potential for developer and operator error, and the difficulty in verification of the spreadsheet and the data it produces. Additionally there are inherent security and audit  \ntrail deficiencies in the standard MS-Excel product, leading many experts to consider spreadsheets as ‘unvalidatable’. These factors have led auditors to consider spreadsheets asa common system in which data can be incorrectly calculated and reported , both due to accidental , and intentional operator actions.  \nMany companies within the pharmaceutical industry initially took the approach of removing, or at least planning to remove, spreadsheets from all critical areas of the business. This approach has had some success; however it has been an extremely costly and time-consuming process and is by no means complete except in a handful of companies. Often the replacement of Excel simply moved the compliance concerns to other systems, and the process of migration greatly inconvenienced a large user base of experienced Excel users and in-use spreadsheets. In addition change always brings about a level of risk, and often migrating the process to a new system actually increases the risks to the data, especially in the short term. Many companies are confident in their data produced from the Excel processes, but have found it difficult to demonstrate that confidence to inspectors and auditors. The argument for maintaining the use of Excel, but in a controlled and validated process is therefore well founded.  \nABB have developed and optimised the validation approach outlined in this series of articles over a number of years, enabling implementation of compliance improvements and improved business processes whilst continuing to use Excel. A major benefit is that the process can be implemented rapidly in all regulated environments; it has been successfully applied to many hundreds of spreadsheets in major pharmaceutical comp","cbCaipnim2Yk1jwH","https://ap.wps.com/l/cbCaipnim2Yk1jwH","pdf",390399,7,"English","# Introduction\n## Does the spreadsheet need to be validated?\n## Inventory and risk-based assessment\n## Spreadsheet validation scope","[{\"question\":\"Why do GxP-critical Excel spreadsheets need validation?\",\"answer\":\"Validation ensures the spreadsheets generate accurate, secure, and auditable data, addressing both potential operator/developer errors and deficiencies in standard spreadsheet security and audit trails.\"},{\"question\":\"How can you decide whether a spreadsheet must be validated?\",\"answer\":\"Determine whether the data flow includes GxP-critical data requiring validation, and identify which spreadsheets within that data flow fall under validation scope.\"},{\"question\":\"What method supports selecting which spreadsheets to validate first?\",\"answer\":\"Create an inventory of spreadsheets, then perform a risk-based assessment of the data used, spreadsheet functionality, and the data reported to prioritize highest regulatory and business risk items.\"}]","A Pragmatic Approach to the Validation of Excel Spreadsheets - Overview | PDF",1789205639]
