ESTUDIO DE FACTIBILIDAD PARA LA CREACIÓN DE UNA EMPRESA DE SERVICIOS DE INGENIERÍA. Freddy Hernán Moreno Lasprilla Carlos Fernando Cuevas Villegas Administración y Contabilidad costo de capital valor presente neto Estructura de capital planeación estratégica En el presente artículo se busca realizarel estudio de factibilidad parala creación de una empresa de serviciosde ingeniería de redes inalámbricasen el área de las telecomunicaciones,apoyado por una estrategiapara la implementación de la empresacon base en el análisis de las cincofuerzas de Porter. De modo que sepueda determinar si es o no competitivacon las empresas extranjeras quebrindan este tipo de servicios en elmercado local, por lo tanto el análisisse realiza fundamentado en losplanes de presupuesto.La utilidad de este documento se encuentraen la utilización de los conceptosde finanzas para estudios de factibilidad y competitividad. Se hacereferencia al concepto de planeaciónestratégica, organizando la informaciónde la industria en el modelo delas cinco fuerzas desarrollado porMichael Porter, para mostrar la factibilidaddel proyecto. 2003 artículo científico 0123-5923 https://www.redalyc.org/articulo.oa?id=21208802 es http://www.redalyc.org/revista.oa?id=212 Estudios Gerenciales application/pdf Universidad ICESI Estudios Gerenciales (Colombia) Num.88
