Information Systems and Strategies
The implementation plan includes planning, training, converting to the new business processes, acceptance testing, and post-implementation auditing; these serve to create a structure in which formal acceptance by the users is likely. Because an enterprise system would demand a large amount of information in a unified database, it might be prudent to also initiate a prototype cycle. The task of implementing an enterprise software solution is a large one, and once implemented it may be difficult to alter. Therefore, a prototype system would certainly aid the task finding flaws and indicating what the final system will need to function optimally.

2.) Models, as useful representations of something that exists in reality, can help determine design strategy for information systems. Two examples of this can be found in mental models and mathematical models.

Mental models encapsulate the unwritten beliefs and assumptions people use when they consider a specific subject. Mental models may include generalizations or certain if-then criteria. For example, a managerÆs mental model may be phrased to say: ôif a salesperson has no experience, then he or she will be easily adapted to company standards and methods regarding how to make a sale." Because our mental models prompt us to seek out certain information, they reflect directly upon the information systems available to us. Thus, if it is understood that the example above does in fact pertain to a manager at a given co

 

Implementation is the third phase. It is the process of introducing the new or improved work system to the organization. At this phase, the software has been tested and is running. Essentially, the implementation phase marks the transition from the old to the new; planning, user training, conversion to the new systems, and follow-up are all prudent steps to take at this point, as implementation may fundamentally alter the ways in which organizations or individuals operate. In this, much can go wrong in implementation. As a safeguard, it is helpful to run the old information system along side the new one. Simultaneous operation of the two systems helps to identify unanticipated problems with the new system that might ultimately need modifications before implementation is complete. Also, with the implementation of the new system, barriers between departments within an organization may be constructed or dissolved. As a result, political issues are bound to emerge. Such issues must be identified and controlled early in order to best deter conflict between users.

The second phase, development, describes the process of acquiring the needed resources for the new work and information system. Hardware, software, and other resources needed to perform IT-related and non-IT-related functions. The key goal of the development phase is to make sure that work system and information system features actually solve the problems that users want solved. The purchasing and testing of equipment is necessary during the development phase, in the interest of identifying(and correcting) programming errors and misunderstandings. Documentation is also created at this time to explain how the work system and information system are supposed to operate. During the development phase, a challenge lies in ascertaining an accurate sense of whether or not the new information system will help the users. It is often difficult for users to anticipate how a new system would help or even hu
