Analysis Of The Sixth System Engineering Process

The fifth system engineering process is identification and prioritization of technical performance measures (TPMs). This part of the process will ensure the designer what is more important (Blanchard). An “objective tree,” like in figure 2 below, may help in facilitating the prioritization task of this process. For instance, is it more important to maximize cost effectiveness or to maximize system effectiveness? In the case of the space shuttle for NASA, they prioritized on maximizing cost effectiveness due to the budget cuts they received during the 1970s (“Challenger…”). They figured it will be more cost effective to have a reusable space shuttle instead of a disposable one. Therefore, they prioritized in designing a reusable space shuttle.

Design is a vital step in the system engineering process. This step applies art, science, affordability, requirement, fulfillment, technology, and integration altogether (Blanchard). Therefore, this step decides what materials to use, how your product will look like, the cost of making the product, and many more. The space shuttle consists of three main components, the orbiter, external tank, and solid rocket boosters (Dunbar). The orbiter design is shown in figure 3 below. This component is the brains of the space shuttle, the crew’s home in space, and the payload’s storage. The external tank design is shown in figure 4 below. This contains pressured liquid hydrogen fuel and liquid oxygen oxidizer for the main engines of the orbiter during lift-off (“EXTERNAL TANK”). This is the largest and heaviest component of the space shuttle. The solid rocket booster is shown in figure 5 below. This provides the main thrust to lift the space shuttle up to an altitude of about 150,000 feet (“SOLID ROCKET…”). Also, this is the major component where the failure
