Tăng cường sự chặt chẽ trong việc chuyển giao thông tin giữa các ngành và các công cụ "14. SysML sẽ được chính thức được thông qua bởi OMG năm 2005. Mục tiêu của bài tập này là để cung cấp kinh nghiệm trong việc phát triển và nêu rõ yêu cầu bằng cách sử dụng một phương pháp musts, mong muốn, và ưu tiên. | 166 THE TEN MANAGEMENT ELEMENTS IN DETAIL the Systems Engineering Domain Special Interest Group SEDESIG . The goals of that group were to Provide a standard SE modeling language to specify design and verify complex systems. Facilitate integration of systems software and other engineering disciplines. Promote rigor in the transfer of information between disciplines and tools. 14 It is expected that SysML will be formally adopted by OMG in 2005. REQUIREMENTS ELEMENT EXERCISE The objective of this exercise is to provide experience in developing and stating requirements using a method of musts wants and priorities. You have decided to purchase a new vehicle. You have not yet decided on the model or brand and want to make certain that you select the best solution for your needs. Make a list of your musts will not buy without them wants not mandatory but desirable and weight the wants according to their importance. The musts need to be strictly quantitative such as must cost less than 35 000 or must have four or more doors. Qualitative statements such as must be low maintenance do not qualify as a must. It is acceptable to have an evaluation factor in both categories. For instance must stop from 70 mph in 170 feet 110 kph in 52 meters can be a must and short braking distance can be a want to give credit to those that pass the must and are better than others at braking. Once you have identified the musts and wants prioritize the wants by selecting the most important want and assign it a weight of 10. Determine the relative importance of the other wants and weight them accordingly. If two or more wants are of equal importance they will have equal weights. The final list with weights provides the evaluation criteria against which alternatives can be scored. Now conduct a sensitivity analysis to ensure that the weights are properly apportioned to your selection objectives so that the many entertainment and convenience features are not unbalancing the selection.
