Abstract- Information Technology is one the most important resources in today’s business environment and successful businesses are investing heavily in IT. In fact in today’s business environment it is impossible to manage an organization without using IT tools and systems. Success of IT systems in an organization depends on many factors that one of them is fitness of used system with organizational working model. We can identify organizational working model by considering two dimensions: level of interdependency and the level of the complexity in work. In parallel with these two dimensions we can introduce two dimensions about IT systems that Used in the organization: business process orientation. Doing so, in this paper four categories of IT systems and tools have been identified that each one is proper for specific organizational working model. So this model could be useful to recognize proper type of IT systems for specific organization based on its working model.
Key-Words: organizational working model, IT systems, process orientation, knowledge orientation
and successful businesses are investing heavily in IT. . In fact in today’s business environment it is impossible to manage an organization without using IT tools and systems.
Experiences show that whenever businesses use IT system that is fit with their organizational structure and working model and also organizational culture, they will become successful in the way of their business and if else they will fail. So before using IT systems in organization at first it is important to know organizational working models that are th
e nature of work in an organization or different departments.
According to  we can consider two dimensions to model the organization: level of interdependence involved - that is the degree to which individuals and organizations need to collaborate and interact and complexity of work involved – the degree to which employees need to apply their judgment and interpret a variety of information. Based on these two dimensions Accenture institution has identified for distinct categories of works, or “Work Model”. (fig. 1)Transaction mode, in which there is a low degree of both interdependence and complexity. Work is typically routine, highly reliant on formal rules, procedures and training and depends on a workforce that exercises little discretion.
Integration model, in which there is a high degree of interdependence and low degree of complexity. Work is systematic and repeatable, relies on formal processes, methodologies and standards, and depends on tight integration across functional boundaries.
Expert model, in which there is low interdependence and high complexity. Work requires judgment and is dependant on “star performer”.
Collaboration model, in which there is a high degree of both interdependence and complexity. Work involves improvisation and learning by doing, and relies on deep expertise across functions and the use of flexible teams.
Considering these organizational working models, we want to introduce a framework for categorizing IT tools and systems in organization. To do so we consider two factors that are business process orientation (that supports work interdependency) and knowledge involved in the system (that support work complexity).
