1. Dilemma of simple questions and known answers: What is the population of Bangladesh now? How many are unemployed? What is the import-export disparity? Simple question, right? And the answer is almost known to everyone. So where is the dilemma? To understand, the following questions should also be considered. Is population a curse or power? What is the idea of reducing the import-export disparity? How can unemployment be reduced? Didn’t you think about the environment in a country like ours with a weak economy? Some questions are more important than thousands of answers. The above questions are the burden of that.

2. Why is reverse engineering and circular economy called co-existent? Companions are those who take the family forward with cooperation, sympathy and unity in difficult times. Sahadar understands the need of difficult times and strengthens each other’s solidarity in the face of it. Before understanding the whole story of the above cohort, let’s know their identity. Reverse engineering is a process that welcomes destruction for the sake of creation, a process that starts from the end of the engineering journey and goes in the opposite direction along the familiar path of engineering. Engineering starts from zero, applying the acquired knowledge and data moves forward towards the target object. On the way, many ups and downs, frustration also gets against the desired results. But the engineers kept full control of this difficult journey in their fists. Reverse engineering, on the other hand, starts its journey based on that mature, usable product or system, trying to understand the needs of each component, their mutual relationships and types of cooperation. Its journey is not as much a friend’s journey as a friend’s engineering journey. However, they do not have full control of their journey. It may seem that reverse engineering does not get the taste of creation, because it walks on the familiar path created by others, where is the opportunity to create here? That’s not the case. They also create the goods or systems of time, society and state. Most of the time it is a slight modification of the final product or system, in some cases a completely new creation. The main differences between engineering and reverse engineering are given below in the form of charts: Feature Engineering Reverse Engineering Course Forward Backward Oriented How to start? Based on the product available in the market through concept or design the goal is to understand some new processes and create replicates Focus on innovation and development, analysis and knowledge accumulation Legality Generally, legitimacy or illegality depends on the final product and its intellectual property rights. Suppose you bring a new smart phone to the market. Then you must start the engineering process. And if you want to know how your opponent’s smart phone works, then you must start the reverse engineering process. The chart gives an idea of the above two processes: Engineering Process Reverse Engineering Process Objective concept: The whole team will work hard to finalize the features of the new smart phone so that it easily creates attraction in the market. Such as advanced cameras, higher speed processors, and long-lasting batteries.
