Ví dụ trong chương này cho thấy tất cả các công cụ và kỹ thuật được mô tả cho đến nay có thể được tích hợp để cung cấp cho một hệ thống quản lý dự án toàn diện | 29 Example of integration of tools and techniques The example in this chapter shows how all the tools and techniques described so far can be integrated to give a comprehensive project management system. The project chosen is the design manufacture and distribution of a prototype motor car and while the operations and time scales are only indicative and do not purport to represent a real life situation the examples show how the techniques follow each other in a logical sequence. The prototype motor car being produced is illustrated in Figure and the main components of the engine are shown in Figure . It will be seen that the letters given to the engine components are the activity identity letters used in planning networks. The following gives an oversight of the main techniques and their most important constituents. As with all projects the first document to be produced is the Business Case which should also include the chosen option investigated for the Project Planning and Control Figure Investment Appraisal. In this exercise the questions to be asked and answered are shown in Table . It is assumed that the project requires an initial investment of 60 million and that over a 5 year period 60 000 cars units will be produced at a cost of 5000 per unit. The assumptions are that the discount rate is 8 and there are two options for phasing the manufacture a That the factory performs well for the first two years but suffers some production problems in the next three years option 1 b That the factory has teething problems in the first three years but goes into full production in the last two option 2 . The Discounted Cash Flow DCF calculations can be produced for both options as shown in Tables and . To obtain the Internal Rate of Return IRR an additional discount rate in this case 20 must be applied to both options. The resulting calculations are 290 Example of integration of tools and techniques Figure The parts of an overhead-camshaft .
