Transforming Business Through Data Quality Improvement
Published: June 1, 1998
1. Create Constancy of Purpose for Data Quality Improvement Deming's first point describes the beginning point of a quality environment: "create constancy of purpose for the improvement of product and service." Constancy of purpose means dedication to quality as a way of doing business. The purpose of this constancy is to become competitive, stay in business, and provide jobs. Business and I/S management must balance two sets of problems: those of today and those of tomorrow. Business failure occurs when management focuses too much attention on today's immediate needs, such as quarterly profits, at the expense of adequately solving tomorrow's problem, such as discovering and satisfying customers' emerging requirements. The pressure of solving today's problems-meeting project target dates, converting applications and databases to support the Year 2000, "fixing" application bugs to get operations back up, cleaning data from legacy databases for the data warehouse -must be balanced with creating tomorrow's solutions. What good is it that applications are "Year 2000 enabled" if the enterprise goes out of business because it was not able to develop applications that drive critical new processes? What good is clean data in the data warehouse if it is the wrong data? What good is measuring data quality if it only leads to finger-pointing, blame and deeper entrenchment into political freedoms of proprietary databases? Deming says no company without a plan for the future will survive. No I/S organization without a plan that positions the enterprise to meet tomorrow's knowledge requirements and the ability to rapidly adapt to new ways of performing business processes can-or should be allowed to-survive. One aspect of constancy of purpose is innovation. Innovation, however, is not innovation for innovation sake. New I/S products and services must not simply be new applications or new technology platforms. Creating a web site because it is the technology du jour is not innovation. What is its purpose? How does it move one to accomplish the mission. I/S must improve how its business partners achieve strategic business objectives, and at the same time improve its end-customers' lives. The ramification is that data producers may be asked to capture attributes about business events that are needed by downstream knowledge workers. These attributes may not be needed within the data producers department, but are required to effectively save the end customer. Constancy of purpose for data quality means that data resource management (DRM) must continually ask, "how are its information products going to capture and deliver knowledge resources that enable the business to achieve its mission, and how will it improve end-customer satisfaction?" It also means application development must continually ask, "how is this application going to support reengineered processes that enable the business to achieve its mission, and how will it improve end-customer satisfaction?" Quality information systems products will be reusable and will require low maintenance. Quality databases will be minimally redundant (except where planned AND managed) and will be reusable by subsequent applications and business areas by simply adding any newly required data and not requiring structural database changes. Quality applications will be non-redundant (except where replacing planned obsolescent applications) and will add value? To achieve quality innovation, Deming says, top management must have a "declared unshakable commitment to quality and productivity". Permanent data quality improvement occurs only when senior I/S and business management recognize two facts. One, the amount of time and money spent fixing today's problems as the result of non-quality data is unacceptable The second fact is that this wasted time results from creating short term non-integrated applications and not spending enough time building a stable and flexible information infrastructure that solves tomorrow's problems. Information systems productivity is not "how fast can we develop and implement an application. Information systems "quality and productivity"-or "qualitivity"-is how it can deliver stable (does not require a lot of enhancement requests) applications as a result of reusable quality components such as shared data. This requires planning and development of reusable information infrastructure components that enable the enterprise to accomplish its mission and continually satisfy its end customers". A critical aspect of constancy of purpose of data quality is that the "obligation to the customer never ceases". I/S products and services must always be planned, designed, built and implemented with the downstream knowledge worker and end customer in mind. The only success measure is how well do they satisfy the end customer and meet their needs and expectations. This does NOT mean how well does it satisfy the immediate users of that application. It DOES mean how well does the product of this application (data) satisfy the downstream knowledge workers needs to satisfy the end customer. The ramifications of Deming's point 1 for data quality are two-fold:
Guidelines for creating constancy of purpose for the improvement of data product quality and service:
2. Adopt the New Philosophy of Quality Data "Reliable service reduces costs," Deming says. Mistakes, rework and delays are what raise costs. Philip Crosby in Quality is Free reconfirms this. The "unquality things," such as doing things over, around, or instead of because of non-quality are the things that increase costs. Quality point 2 really means a transformation of management, according to Deming. Management must dismantle the organizational structures that have created barriers to quality, and caused inefficiency in performing business processes. Data quality point 2 likewise means data quality is no longer optional. Every data warehouse project reconfirms this. The requirement for data quality is driven by the fact that business can no longer afford the luxury of the costs and problems caused by poor quality data. Every hour the business spends hunting for missing data, correcting inaccurate data, working around data problems, scrambling to assemble information across dis-integrated databases, resolving data-related customer complaints, etc., is an hour of cost only, passed on in higher prices to the customer. That hour is not available to add value. Two information product and service facts are also clear: 1. Reliable data management reduces information systems costs Unfortunately, conventional wisdom disagrees. Data management is often perceived as adding costs to an application. To be sure, a data management function that only adds costs to information systems should be eliminated and replaced with an effective value-adding data management program. Data management is not simply developing application-specific data models and defining application data. Quality data management defines and models data that is reusable throughout the enterprise. Quality data management is measured by how much of its defined data and databases are reused and shared. By eliminating the need for redundant applications creating data redundantly, redundant databases, and unnecessary transforming interfaces, quality data management reduces costs of applications development and maintenance, as well as the costs to fix problems caused by inconsistent redundant data. 2. Reliable data reduces business costs Quality data likewise reduces business costs by eliminating the costs of scrap and rework caused by inaccurate or missing data. But more significantly, quality data eliminates missed and lost business opportunity due to poor customer caused by non-quality data. When customers receive poor service because of problems, they may not complain to you. They simply go elsewhere, and take with them their customer lifetime value. If all companies provide the same level of (non)quality, they may simply trade unhappy customers. Even this has costs. It costs 4-5 times as much to gain a new customer as to retain a happy one. But, when someone raises the quality bar, the rules change for everybody. Ramifications of DQ point 2 for information systems management:
Guidelines for adopting the new philosophy of quality data product and service:
Adopting the new philosophy of data quality does not mean saying one believes in it and creating slogans. It means acting those beliefs and changing behavior to make it happen. What do you think?
