3. Executive summery:

3.1 Brief recapitulation of the problem situation:

Volkswagen Ltd is one of the largest car manufacturing companies among its contemporaries. Its engines are in service with more than 25 successful models. The company also supplies marine gas turbines for 25 navies and produces engines for industrial duties such as gas and oil pumping and power generation. However, in recent years there has been a rise in the number of car manufacturing companies. As a result, the competition has increased. The customers have recognised a need for a higher capacity engine and a better turbo speed capacity and a fuel-efficient engine. As a result, the company’s turnover has reduced from what it used to be. In order to stay in the market the company introduced a new design for its engine. It was to have a profound effect on the future prospects of the company and its place in the market. The company made a research into building hydrogen-fuelled engine. With the introduction of hydrogen fuelled engine technology the sales of the cars was not as much as the company expected and the company was not making the proportionate profits. The main problems facing Volkswagen were:

• The newly developed hydrogen engine was very economical means of transport for the people, but the cost associated with the purchase of the car is very huge, which is a major drawback in the sales of the car.

• In the manufacturing of the parts the work-in-progress time and material cost has gone up. The new hydrogen engine. In addition, owing to the high work-in-progress effective inventory control has become a major problem with the company contributing to the increase in the cost.

• It was apparent that the future profit ability of Volkswagen depended on the manufacturing efficiency and the reduction in the cost and improvement of sales of the hydrogen car.

3.2 Definition of the scope of the assignment:

The scope/objectives of the assignment is given as below:

 To choose and examine the appropriateness and practicality of the chosen system engineering design to solve the problem for the first assignment. This is done by applying the engineering specialities which provide the knowledge to specific areas such as Design life cycle costing, verification and validation, logistics and supportability, documentation and specification, quality and performance control, managing changes, managing interfaces, managing human factors, systems engineering management planning, technical management planning, identification of risks.

 To identify the tasks to be performed and to draw a time line diagram.

 To identify the types of requirements in every speciality under consideration and
