Most system development methods, at least in principle, have two important components,rnnamely a modeling language and a process. The modeling languages are graphica lrnnotations for expressing designs and provides easy communication and documentation.rnThe process of the method shows how to do the development process.rnThis thesis uses the Rumbough's OMT (Object Modeling Technique) for the process ofrnthe analysis and designing of information support system for SUR Construction S Co.rnEquipped with th is object oriented methods, the thesis focuses on identifying thernrequirement of the company, depa rtment by department. And then a special focus isrngiven to the material resource of the company. It has been found that almost everyrndepartment is concerned with the material resources, and as such it is a decisive objectrnthat determines the success or fa ilure of the company. Therefore, the necessaryrninformation and operations concerned with this important material has to be identifiedrnand des igned so that every department is provided with the kind of information therndepartment requires for decisions making.rnMany system development efforts are made with very little or no regard to the veryrnimportant aspect of development process, namely, the documentation. Although systemrndevelopment efforts are made in SUR very recent ly it appears no sufficientrndocumentation for the requirement analysis of the company has been made. As a result,rneach is an islands of desperate attempts, that failed to come up with a system that canrnprovide an accurate, timely, and relevant information that the management of SUR needsrnfor decision making and control of operation. This thes is uses the UML as ways ofrncommunicating and documenting the requirement analysis of the company.rnRisk and uncertainty are fact of life. SUR are faced with a multitude of different ri sk andrnuncertainty issues. But the company approaches these unpredictable circumstances ofrnbusiness based on the whims and experiences that can be subject to variation and errors.rnHence it is good to col lect the experience of the domain experts of the company on thernarea and formalize and organize the decisions by clea rly identifying the importantrnvariables both control lable and uncontrollable and describe them through a model. Andrnuse th is model to forecast how each risk circumstance behaves, to make a better decisionrnthat otherw ise would have been cost ly. To this end, th is paper explores the potential ofrnmodels in bidding for a new project with competitors.
