Success Factors for the Implementation of Enterprise Portals

The implementation of enterprise portals is still ranked top on the wish list of many CEOs, expecting that the portal becomes the core system for offering a flexible infrastructure that integrates and extends business applications “beyond the enterprise” (Hazra, 2002). By 2009, the market for application integration, middleware, and portals is expected to grow to $7.1 billion, with a 5-year compound annual growth rate of 2.7% (Correia, Biscotti, Dharmasthira, & Wurster, 2005). The success of enterprise portals is not astonishing, since the portal concepts promise to provide secure, customizable, personalizable, integrated access to dynamic content from a variety of sources, in a variety of source formats, wherever it is needed (Amberg, Holzner, & Remus, 2003; Collins, 2001; Davydov, 2001; Hazra, 2002; Kastel, 2003; Smith, 2004; Sullivan, 2004), enabling core e-business strategies by running supportive portals like knowledge portals, employee portals, ERP portals, collaborative portals, process portals, and partner portals. However, after the first wave of euphoria, the high expectations of companies became more and more realistic, taking into account that portal projects are complex, timeand cost-consuming, with a high risk of failure. In complex portal projects, costs and benefits to build up and operate an enterprise portal are weighed up in a systematic manner, including make-or-buy decisions with regard to packaged portal platforms vs. open source developments, individually developed vs. purchased portal components (so called portlets), and benefits vs. costs to run, maintain, and improve the portal (Hazra, 2002). Altogether, the growing demand for portal solutions is leading to an increasing attention in regard to the management of critical success 1361
