What is the difference between engineering and reengineering

Unlike re-engineering, reverse engineering takes a finished product with the aim of discovering how it works by testing it. Typically this is done by companies that seek to infiltrate a competitor's market or understand its new product.

In doing so they can produce new products while allowing the original creator to pay all the development costs and take all the risks involved with creating a new product.

Analysis of a product in this way is done without technical drawings or prior knowledge of how the device works, and the basic method used in reverse engineering begins by identifying the system's components, followed by an investigation into the relationship among these components.

Reverse engineering is a controversial subject. While the companies performing it may be at a distinct advantage, saving both time and money, the original creator of the design may be severely affected by the increased competition. Although design patents can protect an engineer or company from this kind of activity, the security this can offer is limited. By reverse engineering a product, you can discover original ideas that are not protected; in doing so, you can infringe another's intellectual property rights.

It is therefore important that designs are not disclosed to competitors and protection is in place to prevent fraudulent activity. Reverse engineering and re-engineering of software is becoming increasingly common with our dependence on computers and the internet.

For example, excessive wear might indicate where a product should be improved. To gain competitive benchmarking methods to understand competitor's products and develop better products.

The original CAD model is not sufficient to support modifications or current manufacturing methods. The original equipment manufacturers are either unwilling or unable to supply replacement parts, or demand inflated costs for sole-source parts. To update obsolete materials or antiquated manufacturing processes with more current, less-expensive technologies.

It takes more time to construct or develop an application. Forward engineering is a technique of creating high-level models or designs to make in complexities and low-level information. Therefore this kind of engineering has completely different principles in numerous package and information processes. Forward Engineering applies of all the software engineering process which contains SDLC to recreate associate existing application.

It is near to full fill new needs of the users into re-engineering. Characteristics of forward engineering: Forward engineering is a variety of engineering that has different principles in numerous package and information processes. Forward engineering deals with the conversion of business processes, services , and functions into applications.

In this method business model is developed first. Then, a top-to-down approach is followed to urge the package from the model developed. Forward engineering tools are accustomed move from implementation styles and logic to the event of supply code. It essentially permits the user to develop a business model which may then be translated into data system components.

These tools basically follow the top-to down approach.
