Data Quality Definitions

From Lee, Pipino, Funk & Wang "Journey to Data Quality" (2006)

Data Element: smallest unit of named data that has meaning in the context of the operational environment.

Information Product (IP): a collection of data element instances that meets the specified requirements of a data consumer.

IP-MAP: a sytematic representation of the process involved in manufacturing or creating an information product.

Corporate Household Knowledge: knowledge about organizations and their relationships (a poor definition, but an important concept).  Appears to be the "as-is" business architecture with an RDBMS bent - that is, to address entity identification (what things are the same), entity aggregation (what things to include), and transparency (what is in the lineage).

Enterprise Architecture Definitions

From Christensen, Grossman & Hwang "The Innovator's Presecription" (2009), an example of what can happen without Enterprise Architecture:

Supply Chain Disruption (ASUSTeK disrupting Dell's supply chain) "Just like the types of disruption where an entrant company comes into the bottom tier of a market and then eats its way up-market, tier by tier, the causal mechanism of supply chain disruption is the pursuit of profitability (by the disrupted)." p. 266

From TOGAF v9

  • Architecture is the fundamental organization of something embodied in
    • its components
    • their relationships to each other and to the environment
    • the principles governing their design and evolution
  • Enterprise Architecture is
    • the organizing logic for business processes and IT infrastrcture reflecting the integration and standardization requirements of the firm's operating model (MIT CISR)
    • a conceptual blueprint that defines the structure and operation of an organization.  The intent of an enterprise architecture is to determine how an organization can most effectively achieve its current and future objectives (SearchCIO.com)
  • Architecture Framework is a toolkit which can be used for developing a broad range of different architectures
    • it should describe a method for designing an information system in terms of a set of building blocks, and for showing how the building blocks fit together (MdP: note the tie-in to first two bullet points of architecture definition above)
    • it should provide a set of tools and a common vocabulary (MdP: often called a taxonomy and/or ontology)
    • it should include recommended standards and compliant products for implementing and connecting building blocks

From Mark Lane, personal communication

"The goal of Enterprise Architecture is to define the structures for linking a company’s strategy to its execution.  This vital link captures the corporate vision as blueprints that include enough guidance and detail for the various parts of the organization to execute. Specialized practices are used to determine where the company is today, where it will be tomorrow, and the roadmaps that lead from one stage to the next."

Data Warehousing Definitions

  • It is NOT a Federation of Data (aka EAI/EII/Real-time ETL/Gateway)
  • It is NOT a Data Mart that can be grown into a DWH (aka the Kimball DWH Lifecycle)
  • It is NOT an Activce DWH (aka Operational BI)
  • It is NOT a Dimensional Star Schema (aka a Dimensional DWH)

Healthcare (IT) Definitions

From Christensen, Grossman & Hwang, "The Innovator's Prescription" (2009)

Every Disruption is comprised of three components:

  1. A technological enabler which transforms a technical problem from a complex one into a simple one
  2. A business model innovation which can take the technology to market at low cost
    1. value proposition
    2. resources
    3. processes
    4. profit formula
  3. A value network of suppliers and distributors who's business models are aligned with 1. and 2.

  • "Affordability comes from reducing complexity-driven overhead, and quality stems from rational integration around the jobs of patients" p.422
  • Adam Smith's "Invisible Hand" v. Alfred Chandler's "Visible Hand of Managerial Capitalism"
  • sustaining innovation/competition v. disruptive innovation/competition
  • "Jobs arise in the(lives of customers) that they need to do, and they hire products or services to do these jobs" p.11
  • "Proprietary integration of the company's resources, processes, and profit formula in order to do a job that the custoemr is trying to do is the essence of competitive advantage" p.14
  • "...convenience and cost are not jobs(, j)obs exist independently of a market for products that can be hired to do them(, a)nd the job exists independently of customers as well" p. 17
  • "We know of no business that has successfully housed two fundamentally different business models within the same operating unit." p.76
  • "Only when an organization's resources, processes and profit model are focused around a job-to-be-done can they be intergrated in a correct and optimzed way that does the job as perfectly as possible" p.79
  • "It was only by understanding the jobs to be done that they could see how to correctly integrate, in order to orchestrate ... as perfectly as possible" p.80
  • "Low cost comes from focus.  Quality comes from correct integration to get a job done." p. 96
  • "Quality should only be expressed realtive to the job-to-be-done." p. 122
  • "The value of solving a correctly defined problem is immense, in every industry." p.157
  • The Chronic Quadrangle p. 161
  • "To predict what actions people will prioritize, we need to watch what they do, because we are often misled when we listen to what they say." p. 170
  • "An innovation which makes it easier and cheaper for people to do what they are already trying to do is called a "killer app"." p. 171
  • "Maintaining health is a job that only a minority of people prioritize in their lives.  For the rest becoming healthy only becomes a priority job after they become sick." p. 172
  • "A business model is built around a value proposition that helps a group of customers do more effectively, affordably, and conveniently a job they have long been trying to do.  Understanding the job is a prerequisite to integrating resources and processes in a coherent way that optimally gets it done.  Then and only then can consumers truly be satisfied.  The fact that hsopitals and physicians' practices are not job-focused, but instead aspire to do anything for anybody, has caused them not to be integrated correctly.  In their current configuration, they cannot be consumer-driven." p. 215
  • "When products don't perform well enough or reliably enough, competitive advantage goes to those firms that compete with proprietary, optimized product or process architectures."  p. 267
  • "As a general rule, money is made at the stage(s) in the value chain where the performance of the overall system is determined." p. 278
  • "Many who have written about health-care reform urge in an undifferentiated way for transparency - for disclosure of outcomes data for individual hospitals and physicians.  We have concluded that a key reason why such transparency hasn't emerged is that what these reformers have urged is not just overly simplistic: it is an impossible appples and oranges problem." p. 381
  • "Regulatory insistence on compliance to inputs and process standards eventually can become a hindrance to further innovation if a pioneering company could potenetially figure out a way to deliver superior outcomes by deviating from convention." ppg. 381-2

From James Feldbaum MD in Healthcare Informatics October 2009 

  • Guidelines: Consensus statements that are systematically developed from efficacy and effectiveness research and clinical consensus to assist practitioners in making patient-related management decisions about appropriate care under various clinical circumstances.

  • Clinical Pathways: Also known as “critical pathways,” and represent a “roadmap” of care that allows providers to understand the key goals, diagnostic tests, treatments, and discharge planning activities that should occur to improve outcomes and reduce costs for hospitalized patients. Clinical pathways are often organized into days or phases of hospitalization. They represent a method for monitoring and managing a process by providing a sequence and timing of care.

  • Protocols: Treatment recommendations based on guidelines or policies that are utilized to decrease variation in patient care. Protocols provide an agreed upon process of care for a specific patient population or condition.

  • Order Set: A set of orders routinely issued by physicians in recurring situations in the care of patients with particular diseases or other conditions requiring medical, surgical, and nursing care. The consistent use of order sets is intended to reduce the risk of error, increase patient safety, improve outcomes, and increase efficiency.

  • Philosophical Definitions

    Fallibilism (Charles Sanders Pierce): all knowledge can, in principle, be mistaken.

    Falsifiability (Karl Popper): the logical possibility that an asssertion can be shown to be false by observation.

    • Duhem-Quine Hypothesis: it is impossible to test a scientific hypothesis in isolation because it rests on one or more background assumptions (i.e. hypotheses).
    • Scientific Paradigms (Thomas Kuhn): what members of a scientific community and they alone share.
      • my interpretation - paradigms are the hypotheses being tested and their background assumptions.
    • The notion that theories are more or less fit to a problem set
      • my interpretation - that falsifiability is like extinction and that verifiability is like selection
    • That theories need no justification i.e. there are no such things as good positivist reasons, but that theories with justification may be fitter
    • That a falsified/false theory may still yield satisfactory predictions, but that an unfalsified theory with satisfactory predictions is fitter
    • That unfalsifiable theories may still yield productive research programs (Darwinism) and are therfore fitter than unfalsiable theories which do not yield productive research programs

    Reflexivity: any situation where causality is bidirectional between cause and effect.
