process iteratively enables the process to be executed by incrementally aligning the product to be implemented with the end-user (organization). Embedded & Generic methods One way to implement product software is through usage of an embedded method or model. Embedded models are part of the auxiliary materials (see: definition of product software) that come with the software package. Implementing a software product using an embedded model implies not only that the model is (mostly) only usable with the specific software product, but also that the product can or should only be implemented using the model. Embedded methods can thus be seen as very specific ways implementing product software. Examples of software products with an embedded method are: Implementing SAP (SAP R/3), using the ARIS embedded model. Implementing the Baan ERP system, using Dynamic Enterprise Modeling (DEM). Implementing Oracle E-Business Suite, using Oracle Application Implementation Method (AIM). Generic implementation methods are not meant for a specific software product but for common usage in implementing product software products. This usage is going to be elaborated on using the example of implementing product software using Object Process Methodology. This methodology is very useful in for example ERP modeling: the modeling of ERP systems in order to implement it into an organizational structure. Assessments Using an embedded method brings the power that the method is designed to implement the software product that the method comes with. This suggests a less complicated usage of the method and more support possibilities. The negative aspect of an embedded method obviously is that it can only be used for specific product software. Engineers and consultants, operating with several software products, could have more use of a general method, to have just one way of working. Using a generic method like ERP modeling has the power that the method can be used for several ERP systems. Unlike embedded methods, the usage of generic methods enables engineers and consultants that operate in a company where several ERP systems are implemented in customer organizations, to adapt to one specific working method, instead of having to acquire skills for several embedded models. Generic methods have however the lack that implementation projects could become too situational, resulting in difficulties and complexity in the execution of the modeling process, as less support will be available.
