Logical Models Logical models are the simplest method used to determine system requirements. If this , then . This modeling tool is very effective for designing simple operations for a company, but lacks the complexity needed to develop a system that will effectively and efficiently manage a larger technology system. In addition to these other programming tools, there are also linear programs that can be used to determining the correct allocation of resources for a business. Linear programming looks at historical data regarding the resources used in a business operation and helps to determine the optimal solutions for the business working within the known constraints of the business.
Linear programming can be a simple or as complex as wanted.
The complexity of this model is determined by the nature of the business and the demands of management. Ultimately the tools used within the requirement studies process will shape the end business system the company chooses. The more complete the study that is performed, the more likely the end result will manage the business process effectively and efficiently. There are many trade-offs between these modeling tools. The main drawback is that the more complex the modeling tool used, the more time consuming and expensive the process is.
