The Data Quality Landscape – Q1 2017
Data quality is not a new subject: we are all familiar with examples of letters and forms being sent to out-dated addresses, possibly multiple times. Some data quality issues cause more serious consequences than mis-routed mail or delays in processing utility or bank forms. The Mars Climate Orbiter spacecraft was lost due to a mismatch of imperial and metric units for rocket thrust, causing the craft to crash. In between these extremes there can be embarrassing and costly data quality problems. One well-known phone company ordered a huge consignment of display boxes for a new brand of phone, and only when lorries started to roll into warehouses was it discovered that the dimensions of the boxes had been specified in cm rather than mm, resulting in boxes being manufactured that were exactly ten times too large in each dimension. There are many aspects of data quality. Accuracy of data is one thing, but so is completeness (is all the data that you need present?), currency (is it sufficiently up to date?) and relevance.
As long as human beings are involved in capturing data, there will be issues with data quality, and
it was natural that technology be brought to bear to address this problem. Data quality technology typically provides a range of capabilities. These include “profiling” of data, where an initial assessment can be made to understand the scale of problem, through to defining business rules for correcting common errors, to matching potential duplicates using algorithms. Beyond this, some data may be enriched e.g. a precise geocode can be added to an address, and indeed supplementary information can be provided to supplement the original data. For example, a tool might be given a business address and be able to recognise that this address is owned by a certain company where a number of staff are employed, and even link back to business databases to tell you about the size of that company, or its credit rating. A residential address might be recognised by a tool as being in a certain voting district, or even within a flood plain, useful if you are an insurance company. Data quality is not just a one-off exercise. Once you have made an effort to improve data quality, you will want to monitor it on a regular basis, and see whether trends appear over time in the quality of the data. Modern data quality tools can do all these things and more.
The technologies on the market have a wide range of capabilities. Some focus on name and address validation for mass mailing, using algorithms to detect common misspellings of names and addresses, or having glossaries that understand common synonyms for names e.g. “Bob” and “Robert”. Others have much broader functionality and, naturally enough, the more functional products may have a much higher price tag than the more basic ones. Although name and address is the most common area addressed in data quality, product data is another broad domain requiring different approaches, and indeed business rules can be defined and applied to help with data quality across a wide range of data domains. Some data quality products are stand-alone, while others link to separate master data or data governance tools with varying degrees of smoothness.
The diagram that follows shows the major data quality vendors, displayed in three dimensions. See later for definitions of these.
It is important to understand that this is a high-level representation of the market, with vendors represented on the chart specialising in different areas and at very different price-points. If you are considering data quality software, it is important to tailor your selection process to the particular needs that you have rather than relying on high-level diagrams such as this. The Information Difference has various detailed models that can assist you in vendor selection and evaluation.
As part of the landscape process, each vendor was asked to provide at least ten reference customers (some vendors provided over 50 references), which were surveyed to determine their satisfaction with the data quality software of the vendor. The happiest customers based on this survey were those of Innovative Systems, followed by Datactics and HelpIT, then those of Experian and Trillium. Congratulations to those vendors.

The Information Difference Landscape diagram shows three dimensions of a vendor:
▪ Market strength
▪ Customer base.
“Market strength” is made up of a weighted set of five factors: revenues, growth, financial strength, geographic scope and partner network. Each of these individual elements is scored, the total producing the “market strength” figure. Similarly “technology” is made up of four factors: “technology breadth” (the coverage of the vendors in various data quality areas as illustrated below), the longevity of the software in the market, analyst perception of the product via briefings, and customer feedback from reference customers (this has a high weighting), which we surveyed. In each case the scoring is on a scale of 0 (worst) to 6 (best).
Vendors were asked to submit answers to various questions via a questionnaire. Vendors were interviewed directly by an analyst and their software demonstrated and assessed. Reference customers were surveyed to give their experience of the software of each vendor. The technology functions which the vendors were asked about are as shown below. These are drawn from the Information Difference vendor functionality model; if you are interested in more detail on this then please contact The Information Difference.
