The fundamental reason of inculcating design principles is to reduce the cost of development.
Artists aim at keeping things simple and straight forward (Akdeniz). One of the basic rules of design is keeping things simple and stupid (KISS). Avoiding the complexity and sticking to simplicity is the key to efficient design. Also to this, the abstraction principle further supports the art of programming as an art since significant pieces of program functionality are only implemented once. Artistically, an element should not consist of unwanted elements that are not required. In a similar manner, programming design principles propagate that one should avoid adding unwanted functionality in a system. In a nutshell, the application of design principles enhances the elimination of redundancy as they offer advice on the need to eliminate the unwanted repetition (Brooks). The open-closed principle rules that the entities in the system such as classes, functions and modules be open for extension but closed for modification. It is this principle that propels the aviation industry in design high-end, simulated and secure programs. Proper design promotes code reuse that saves time and cost significantly and enables the construction of robust systems. For these reasons, the design serves as the key to making shorter and efficient programs.
Economic Impacts.
Since its conception, the aviation industry has undergone numerous changes and developments to acquire its current status. According to travel and transportation statistics, air travel is constantly on the rise. For 12 years (from 1990 to 2002), a 70% increase in greenhouse gas emissions have been recorded (Capoccitti, Khare and Mildenberger). The annual growth of worldwide air travel is recorded to 5% with China contributing to the highest number of 12% annually. Competition is evident in the commercial sector. Nearly 10,000 airports are serviced by 15,000 aircraft services operating on routes approximately 15 million kilometers.
