Question1 Week 2 – Shadow Systems

According to Jones et al.(2004), A shadow system is a set of data outside the shadow ERP system for business functions. It may be a Spread sheet or Access database, Word document or a complete application system. Important factor in determining system spectral information contained in the ERP system is stored outside the database, ERP system, the information will be used to run the business. The extract will be stored longer than the default. The system is based on the specified index is created in the ERP system, such as a personal identification number.
Jones et al. (2013), mention about shadow systems can be classified into another groups, such as Real Shadow System. This includes the loading of data into the ERP database to a spread sheet or document information added to the data management, business process, and then the data over time. Moreover, Auxiliary Shadow System, this includes the complete contact information through the ERP system or data extracts and indexes are not part of the actual ERP system.

What threat do these systems pose to integration?
ERP systems are designed to provide accurate information in real-time. The shadow system will be separate from the ERP to provide information that is not readily available to other agencies that can result in a decision data is incorrect or incomplete. There is also a risk of lower production increased resource loss systems separate the expected benefits of the system is not aware of the agility to collaborate effectively flow for the satisfaction of customers or a reduction of expenses (Behrens 2009). Shadow systems are friction and low productivity. They are costly to develop and maintain, as they have evolved in size. Also, the complete lack of reporting too as they evolve randomly without a plan. Business itself is affected by the system because there is no reliable ERP, business can not achieve the desired goal of ERP systems are designed to provide accurate information in real-time in the company.

Who or what else might be threatened by the existence of these systems?
Not only employees be affected from the shadow systems. But also to suppliers or customers that are involved in the ERP system will also threatened and integrated collaboration is critical to ERP systems, and to share data instantly through ERP and so the shadow systems will ‘participate’ immediately as If the shadow systems appears without any control of the company and are suffering from the consequences. One of these threats is associated with the original system used to manage the organization as they had to work even after the ERP system has been implemented (Behrens & Seder 2004).

Conclusions and Future work
One of the major ERP implementation is full integration of the business. Report of the shadow systems in the post ERP implementation suggests that this is not always the case. The use of exploratory case studies as the coding technique based on the theory of this study was to study how the shadows systems are after the ERP. In my opinion, I think the shadow system provides a theoretical framework which suggests that factors common in this type of technology, business organization and how everyone involved in the phenomenon in the context of shadow system in ERP context.
