Nowhere in current literature does a high-level model exist that explains ERP in an easily understandable format. Many vendors have in-depth brochures and white papers that explain what their products are capable of, yet some still battle to comprehend fully what it is. Many people, however, are familiar with the 4Ps marketing model. The 4Ps marketing model was a general marketing model where the Ps originally stood for people, product, promotion and price (Alexandrou, 2002). This model was used extensively during the 1980s and 1990s. Over the years, this model has been changed to become a business model and was modified by replacing promotion and price with process and performance. This modified 4P business model was used to construct the proposed conceptual ERP model because most of the people in management are familiar with the concept of the 4Ps.
