The Data Quality Assessment Framework shows you how to measure and monitor data quality, ensuring quality over time. You’ll start with general concepts of measurement and work your way through a detailed framework of more than three dozen measurement types related to five objective dimensions of quality: completeness, timeliness, consistency, validity, and integrity. Ongoing measurement, rather than one time activities will help your organization reach a new level of data quality. This plain-language approach to measuring data can be understood by both business and IT and provides practical guidance on how to apply the DQAF within any organization enabling you to prioritize measurements and effectively report on results. Strategies for using data measurement to govern and improve the quality of data and guidelines for applying the framework within a data asset are included. You’ll come away able to prioritize which measurement types to implement, knowing where to place them in a data flow and how frequently to measure. Common conceptual models for defining and storing of data quality results for purposes of trend analysis are also included as well as generic business requirements for ongoing measuring and monitoring including calculations and comparisons that make the measurements meaningful and help understand trends and detect anomalies. Demonstrates how to leverage a technology independent data quality measurement framework for your specific business priorities and data quality challenges Enables discussions between business and IT with a non-technical vocabulary for data quality measurement Describes how to measure data quality on an ongoing basis with generic measurement types that can be applied to any situation

After realizing the importance of data, organizations have begun to view data as a critical asset, being equally important as other assets such as people, capital, raw materials, and facilities. In order to ensure data are fit for the purpose, there is a need to have high quality levels of data. This book will provide an integrated approach by combining data quality and process quality approaches for ensuring robust quality. When the two concepts are combined, industry can achieve rapid improvements with accurate results and decisions. The methodology is combined with data quality, Lean and Six Sigma philosophies. The approach will guarantee improvements and stable operations.

This book provides essential insights on the adoption of modern software engineering practices at large companies producing software-intensive systems, where hundreds or even thousands of engineers collaborate to deliver on new systems and new versions of already deployed ones. It is based on the findings collected and lessons learned at the Software Center (SC), a unique collaboration between research and industry, with Chalmers University of Technology, Gothenburg University and Malmö University as academic partners and Ericsson, AB Volvo, Volvo Car Corporation, Saab Electronic Defense Systems, Grundfos, Axis Communications, Jeppesen (Boeing) and Sony Mobile as industrial partners. The 17 chapters present the “Stairway to Heaven” model, which represents the typical evolution path companies move through as they develop and mature their software engineering capabilities. The chapters describe theoretical frameworks, conceptual models and, most importantly, the industrial experiences gained by the partner companies in applying novel software engineering techniques. The book’s structure consists of six parts. Part I describes the model in detail and presents an overview of lessons learned in the collaboration between industry and academia. Part II deals with the first step of the Stairway to Heaven, in which R&D adopts agile work practices. Part III of the book combines the next two phases, i.e., continuous integration (CI) and continuous delivery (CD), as they are closely intertwined. Part IV is concerned with the highest level, referred to as “R&D as an innovation system,” while Part V addresses a topic that is separate from the Stairway to Heaven and yet critically important in large organizations: organizational performance metrics that capture data, and visualizations of the status of software assets, defects and teams. Lastly, Part VI presents the perspectives of two of the SC partner companies. The book is intended for practitioners and professionals in the software-intensive systems industry, providing concrete models, frameworks and case studies that show the specific challenges that the partner companies encountered, their approaches to overcoming them, and the results. Researchers will gain valuable insights on the problems faced by large software companies, and on how to effectively tackle them in the context of successful cooperation projects.

Technologisch ist die Integration einer großen Menge von heterogenen Benutzern in ein IT-System heute problemlos möglich. Die Herausforderung besteht darin, neue Arten von Zugängen zu schaffen, die unterschiedlichen Nutzergruppen die jeweils für sie passenden Informationen gleichzeitig bereitstellen. Die unerfahrenen Nutzer benötigen einen Einstieg in das System, der sehr schnell einen Überblick über die vorhandenen Daten liefert. Normale Nutzer brauchen eine konsolidierte Beschreibung, die es ihnen erlaubt, bei Bedarf über ein Drill-Down mit den Daten im System zu arbeiten. Professionelle Nutzer erhalten eine spezifische und sehr genaue Beschreibung, um einen vollständigen Überblick zu erhalten und die Informationen für ihre Zwecke zu verarbeiten. Metadaten liefern eine gute Möglichkeit für einen solchen Zugang. Ein geeignetes, systematisches Vorgehen zur Beschreibung und Verwaltung von Metadaten ist hierbei im Moment noch nicht existent. In dieser Arbeit soll ein erster Ansatz für eine allgemeine Metadaten-Verwaltung geschaffen werden, welche es erlaubt, Metadaten zu definieren, abzulegen und zu nutzen. Für die Definition wird ein modellbasierter Ansatz verwendet. Für das Modell wird ein allgemeines Metadatenschema konstruiert, das auf Stereotypen basiert. Um die Stereotype zu nutzen, wird der Prototyp eines Mediators vorgestellt, der für das Importieren und Exportieren von Metadaten in die Stereotype verwendet werden kann. Zusätzlich werden für das Retrieval von Metadaten automatisiert Strukturen generiert, die zu einem Data Dictionary führen, das dem Konzept in relationalen Datenbankmanagementsystemen ähnelt. Zuletzt wird das Konzept in die Website des deutschen Koordinationsbüros des Internationalen Kontinentalen Tiefbohrprogrammes in Deutschland (ICDP) integriert.
