Data Quality is the foundation for all data and systems activities within a corporation. Quality data is required to deliver correct information to decision-makers who will leverage it to gain a competitive advantage in the market.

Bardess will work with your team to assess data quality across the enterprise or within specific business functions. We will identify key data elements and business rules, assess data for common defects, create rules or recommend actions for fixing data, and create metrics to detect defects as they enter a system/database.


The Bardess Data Quality Analysis Methodology

The Bardess Data Quality Analysis Methodology is comprised of eight primary offerings. Our consultants will work to develop an entire quality program or augment your current data quality initiatives in any stage where you need outside expertise.

Data Assessment Plans

Bardess consultants will work with you to set objectives and develop a comprehensive plan to assess your data assets. The plan will help you to identify your assets and target areas for analysis and improvement. In addition, we will assist you in structuring a work plan to identify source systems, system interfaces and data repositories needed to support key target business functions and data needs, assess system data quality and usability, identify data flow gaps, cleanse or regenerate data, and measure the results.

Data Inventory and Classification

Bardess will perform a detailed inventory of your data assets and systems and classify the information into identifiable groupings. We will identify legacy data repositories needed to support key business functions and their underlying sources of data, as well as interfaces. We will assist in determining the main data sources and additional adjunct data requirements to support the business functions. Bardess will develop an inventory catalog of legacy systems and associated table and data element listings. The process will include identification of key master file data (customer, product, service, entitlement masters) within and across all relevant systems.

The following tasks may be performed for both the legacy and new systems structures.

  • Identify current objectives and plans
  • Identify and review Legacy data sources
  • Identify what data is applicable to the target system
  • Determine existing data stewardship and ownership responsibilities
  • Determine interfaces to data sources and related functionality
  • Determine existing data stewardship and ownership responsibilities
  • Classify data into logical grouping

Data Flow Analysis

Bardess will perform a Data Flow Analysis for your company or business function. The analysis involves a detailed evaluation of existing corporate data from legacy systems as well as data that was extracted, moved, or changed during migrations to new systems. We analyze the data flows and identify the true meaning of the data and how it is used by business functions. We will document both the existing As-Is and the future To-Be flows from a logical business model perspective as well as through physical database designs.

Business Rules Discovery

The Business Rules offering encompasses the identification and documentation of business rules defined by business owners. Bardess will gather, classify and prioritize rule information from business owners and obtain success-level criteria. The rules may be obtained from a variety of methods including facilitated user workshops and structured, one-on-one interviews. Bardess can work individually with your business team to create the business rules or lead workshop sessions to identify rules. Bardess will document the rules and identify gaps based upon initial assessments and obtain concurrence from the business owners.

Data Assessment

The Data Assessment encompasses the most critical activities within the Data Quality Analysis. It is the cornerstone supporting all subsequent analysis activities. In this comprehensive offering, Bardess will perform an inspection and evaluation of key data elements in your installed systems or those defined for migration or data clean up. The assessment may be performed throughout the enterprise or on targeted functional business systems.

During the assessment process, Bardess will uncover anomalies or inaccuracies in the data and focus upon the impacts to business rules, conversion issues and target functionality impacts. Each data element will be assessed using a variety of measurements intended to highlight and delineate the validity, usability and consistency of the data.

Bardess will perform 10 critical assessment tests on your data consisting of Primary Data Quality (PDQ) Assessments as well as Pragmatic Information Quality Assessments.



Primary Data Quality Assessments:

Bardess will assess and measure the physical correctness and accuracy of the data using three types of tests. These tests ensure that the data is of high quality for corporate information systems.


  • Standardized Physical Data Assessments – Completeness, Uniqueness
    These primary Data Assessments can be carried out without working knowledge of existing business rules. The assessments are carried out across all rules and are an aid in identifying fields for business rule definitions and integrity testing.


  • Customized Physical Data Assessments – Validity, Integrity, Referential Integrity, Consistency
    These Customized Assessments are directly driven by business defined rules. The tests are usually applied after the business users have determined the specific fields and business rules to be tested. The tests may identify data gaps and the results may serve as primary input into remediation planning.


  • Data Accuracy Assessments – Accuracy, Timeliness
    These Assessments are driven by business definitions and functional requirements. The tests are among the most difficult and are usually performed on business-critical information. The tests aid in identifying fields for business rules definition and integrity testing and assist in measuring progress and the acceptability of business remediation efforts.


Pragmatic Information Quality Assessments:

Bardess will assess whether the accurate data provides useful information to the Enterprise by a qualitative group of assessments. These tests ensure that the high quality data in corporate information systems is of value to the business users. Valuable data has meaning (clear definitions) and an understandable presentation to the user. Bardess will work with your business users to ensure that data is presented in a way to support the processes within your Enterprise.

Data Gap Analysis

In the Gap Analysis stage, Bardess will identify, quantify and summarize data gaps using the output from the Data Assessment stage. We will produce gap analyses by system, release and/or defined grouping of data elements. The following activities will be performed:

  • Analyze results and identify data gaps
  • Develop summary-level reporting identifying the overall impact of gaps
  • Segment and report gaps based upon the degree of non-compliance and their overall impact
  • Provide detailed reports, where necessary, identifying the record and each identified gap requiring resolution by data element

  • Gap Reporting


Data Improvement and Remediation Plans

Bardess will develop a Remediation and Improvement Plan based upon previous data assessment and gap analyses. We will develop several options for resolution and/or correction of the identified data gaps as well as identify data enhancement and data regeneration requirements for business critical data. Understanding where your inaccurate data resides will allow you to prioritize where the most effective areas for remediation are located. The planning activities may include the following:

  • Analysis of trends and overall impact of gaps identified in previous gap analysis stage
  • Prioritization of gaps by business owners
  • Remediation plan development segmented by business owner
  • Enhancement plan development
  • Communication and coordination with business owners to finalize option(s) chosen for remediation and timelines


Bardess will develop remediation plans based upon the overall migration strategy. The remediation may occur in existing (Legacy) systems, in Data Link Repositories or at the time of conversion to a new system.

In addition, any plans to improve the data will be addressed. This may include addition of data fields to add useful information, use of standardization tools, or verification and/or regeneration of business critical fields with a cost/benefit analysis.

Quality Measurement and Tracking

Bardess will develop quality progress reporting and data quality dashboards to measure and track the data quality improvements. We will develop Data Quality Indices (DQIs) to identify the quality of key data fields that impact the business functions. These key data quality metrics will be incorporated into the Tracking Reports and Quality Dashboards.

Bardess consultants will work with your team to:

  • Develop standardized methods for business owners to provide status of progress as it relates to remediation plans
  • Confirm and validate data updates/corrections based upon business owner progress reporting
  • Develop tracking tools to provide summary-level progress reporting and detailed comparisons
  • Develop processes to communicate results and validate the remediation plan data improvements back to the business users, including incompleteness or inaccuracies.
