Herramienta de software para la enseñanza y entrenamiento en la construcción de la matriz DOFA Amparo Mariño Ibáñez Félix Antonio Cortés Aldana Luís Alejandro Garzón Ruiz Ingeniería software matriz DOFA análisis situacional Planeación estratégica En la actualidad, la mayor parte de las empresas usan la planeación estratégica. La planeación estratégica analiza la situación actual y la futura esperada, determina la dirección de la compañía y desarrolla los medios o estrategias para lograr la misión. Este artículo tiene dos propósitos. Uno, el de revisar ciertas consideraciones generales sobre planeación estratégica empresarial. El segundo, presentar una herramienta computacional que apoye la elaboración de la matriz DOFA para relacionar las amenazas y oportunidades del entorno con las debilidades y fortalezas, especialmente, de una empresa. Los pasos del ciclo de desarrollo de sistemas para desarrollar el software fueron: análisis, diseño, implementación y uso. Para el análisis fue importante la revisión de la literatura sobre planeación estratégica y análisis DOFA. El software sólo automatiza un aspecto de todo el proceso de planeación estratégica y puede ser utilizado para mejorar la capacitación en el análisis DOFA de estudiantes y miembros de la empresa. Con este tipo de trabajos se busca promover la realización de investigaciones interdisciplinarias. 2008 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64328324 es http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.28
