4 Why Data Quality?To realise the full potential of the GDSN, Trading Partners must ensure the following:Accurate product information is aligned across internal manufacturer systemsGood quality product information is synchronised through the GDSNProduct information within retailer systems is aligned with product information received via the GDSNThe industry must be able to trust the quality of data flowing through the GDSN!
5 Why Data Quality? (Cont’d) Without reliable data in the Network, trading partners are forced to set up additional means to control data quality, resulting in a longer, more complicated ‘road’ for the information.
6 Why Data Quality? (Cont’d) The impact of bad data is highlighted on data synchronisation processes, but has consequences for all the processes in the supply chain!Benefits obtained by doing data synchronisation will be nullified if data is erroneous and trading partners are forced to correct it.The impact of bad data is multiplied when considering the cost of initially creating the (bad) data, plus the cost of correcting it and compensating for the problems it caused.
8 What is Data Quality?In order to achieve objectives on data quality, trading partners must agree on a clear vision of what can be considered ‘good quality’ data.Additionally, data quality is the shared responsibility of manufacturers and retailers:Information providers are the source of the product data and so are the starting point for needed improvements in process for creating good dataInformation recipients have responsibility to maintain accurate data within their systems and ensure its integrity in their processesTrading partners must work together in order to assure the right conditions exist for developing data quality initiatives.

10 Data quality must be sustainable throughout time! Pursuing Data QualityData quality must be sustainable throughout time!Short-term ‘remedies’ for data quality may yield some quick results, but maintaining them through time is an resource-exhaustive activity and still will not provide the desire data quality objectives.
11 Pursuing Data Quality (Cont’d) In order to have a sustainable approach for data quality, trading partners must become engaged in several actions that complement one another and help to maintain quality on the dataA central component to these effort is having internal processes that result in a consistently good quality data output
12 Actions for Data Quality Trading partners must collaborate and establish the right set of actions to guarantee quality through time.+Product inspectionsCumulative costEducation and trainingData Quality Management SystemInternal Data Alignment--+Sustainability in Time
13 Constant data corrections and fixes Why are internal processes important: The “Leaky Pipes” of Data QualityInternal processesInternalProcessConstant data corrections and fixes
14 How to get there?The Industry has realised that in order to achieve sustainable data quality, internal processes must be shaped to build a sustainable cycle.This realisation led to several key Industry organisations to collaborate on the development of a unified approach and solution to data quality.This resulted on the Data Quality Framework which is now under the stewardship of GS1.
15 Data Quality Framework: Key DefinitionsData Quality:The desirable characteristics of data when published by trading partnersComplete, standards based, consistent, accurate and time stampedData Quality Framework:Best practices for the management of data quality systemsDepending on market needs, compliance can be demonstrated through:Self-declarationThird party certification based on inspection and auditing
16 Key Definitions (Continued) Internal Data Alignment (IDA):Internal management of data across various business systems to achieve data qualityOne aspect of achieving data qualityMeasurement Services:External measurement service to help businesses publish accurate dimensional dataOffered by several GS1 Member Organisations and Data PoolsVoluntary or mandatory based on market agreement

19 An Industry Call to Action … In late 2004 / early 2005, a number of different industry and country-specific work groups were independently formed to address the data quality issueHowever, the work groups encountered the risk of creating multiple solutionsAs a result, in April 2005, the GCI Executive Board recommended the creation of a Joint Business Planning Data Accuracy Task Force… with the charter to develop a framework for a global data quality solution
20 Achievements of the Data Accuracy JBP Created Data Quality Framework, including:Data Quality Guiding PrinciplesData Quality Protocol (for industry review)Data Quality Management System (DQMS)Data Inspection ProcedureAligned with, or considered, other industry initiativesMeasurement Tolerances Data Accuracy GSMP Project TeamInternal Data Alignment (IDA) methodologiesAgreed an industry governance model and transition and hand-off to GS1 (GDSN)
21 Further developments … In GS1 collaborated with AIM and Capgemini to develop a self-assessment module which would allow organisations to conduct assessments of their compliance with the Data Quality Framework.Within that work, a KPI model was also developed as a means to monitor the actual accuracy of data and validate the effectiveness of internal processes for data quality.A new version of the Framework was then produced including the self-assessment module and the KPI model.This new version was approved by the Steering Committee on January 2008.
23 Governance and Management Upon being entrusted with the stewardship on the document, GS1 (under GDSN) created the Data Quality Steering Committee as the group responsible to manage and maintain the Data Quality FrameworkData Quality Steering Committee reports directly to GDSN BoardThe Data Quality Steering Committee has established a sub-group called the ‘Data Quality Adoption Group’ and has commissioned it with the task to further develop education, communication and tools to support the adoption of data quality and the Data Quality Framework.

33 Data Quality Management Systems Requirements (Chapter 3 of the Framework) III Closing the circle:Internal auditsManagement reviewContinuous improvement
34 Compliance Assessment Conformity with the Framework can be proven through:Self-declaration (Chapter 4)Chapter 4 provides guidance for organisations undertaking an assessmentThird party auditing (Chapter 5)Chapter 5 provides requirements for the third party auditors
35 Self-assessment (Chapter 4 of the Framework) I Chapter 4 contains a procedure that organisations can use to assess their compliance against the Framework (requirements from Chapter 3).Self-assessment procedure may be performed in isolation or with assistance to record results.Organisations may define the scope of the assessment (processes included, goal and timeframe)
36 Self-assessment (Chapter 4 of the Framework) II Self-assessment questionnaire consists of a total of 74 questions that assess conformity with the requirements on Chapter 3.Questions are divided in basic questions (34) and general questions (40). An organisation willing to self-declare must score at least a total score of 80% and fulfil all the basic questions.The results of a successful self-assessment must be validated by high marks on the KPI model.Organisations may wish to assess individual processes in order to identify opportunities for improvement.
37 Self-assessment (Chapter 4 of the Framework) III The KPI model covers the following categories:Overall item accuracyGeneric attribute accuracyDimension and weight accuracyHierarchy accuracyActive/OrderableKPIs can be inspecting using the product inspection procedure (Chapter 6)Recommendation for ‘benchmark’ goals on the KPIs
38 Inspection procedure (Chapter 6 of the Framework) Comparison of a sample size of actual product against related dataLimited to 15 key attributesProcedure prescribes best practices for sample size, measurement methodology and result analysisKPI Model used to monitor progress and upgrades on the accuracyProcedure(s) can be used to be used:InternallyBy Third partyAs part of an audit or as a best practice
