Let’s say you work at a sandwich store. A customer comes and orders a sandwich without any specifications. What would you do? What all fillings would you add? Would there be cheese? Will it be grilled or not? There are many questions. To make a perfect sandwich, you will have to ask your customer in the end. Right?

If you had all the specifications of your customer well in the beginning, wouldn’t the process become better?

Similarly, here, our mobile app is our sandwich and the sandwich maker is the project manager of an app development company. Without understanding more about your final product starting with the development process is difficult. Even if you were able to create an iOS and Android app, most probably the idea would fail.
