A requirements engineering approach based on the alignment of data warehouses and business strategy

Garantizar que los almacenes de datos estén alineados a la estrategia del negocio es primordial para su éxito, ya que estos son utilizados por los gerentes del negocio con el fin de analizar los datos estratégicos de la organización. En este trabajo presentamos un enfoque de ingeniería de requerimientos orientado al negocio que alinea el Almacén de Datos a su plan estratégico. El proceso se describe mediante un conjunto de directrices que incluyen: el análisis VMOST para obtener los objetivos desde los usuarios, el modelo BMM para comprobar que los objetivos definidos estén alineados con la estrategia, el modelado de objetivos por medio de i* con el fin de obtener los requerimientos de información del Almacén de Datos, y el modelado multidimensional mediante un perfil UML. Se presenta un estudio de caso para mostrar el proceso completo.Ensuring that data warehouses are aligned to the business strategy is critical for their success, as these are used by business managers to analyze the organization's strategic data. An approach to requirements engineering-oriented business that aligns the data store to its strategic plan is presented. The process is described by a set of guidelines that include: VMOST analysis to obtain the objectives from the users, the BMM model to verify that the defined objectives are aligned with the strategy, modeling objectives through i* to obtain the information requirements of the data warehouse and multidimensional modeling by UML profile. A case study to show the entire process is presented.Este trabajo se ha realizado con el apoyo de la Dirección de Investigación, Vicerrectoría de Investigación y Postgrado de la Universidad de La Frontera, a través del Proyecto de Investigación DIUFRO DI11-0044

How Do Business People Rank Requirements Representations for Information Systems?

The research question that summarises the primary research goals is: How do business people rank their intentions to use different requirements representations for information systems? An additional goal of the research is to understand the determinants that contribute to these intentions. Business people in this research are defined as working people who are not in an information systems role. The requirements representations evaluated were Prose Narrative, Image Narrative, Diagram Narrative and Video Narrative. The results of this research show that business people rank their intention to use the requirements representations in the following order: Prose Narrative, Image Narrative, Diagram Narrative and Video Narrative. The determinants that influence the intention to use a representation are: Job Performance, Effort, Attitude to a Representation, Social Influence, Facilitating Conditions, Self-Efficacy, Anxiety, Freedom of Choice, Experience, Age and Gender. This research shows that the influence of each of these determinants on the intention to use a representation is significantly different for each requirements representation
