I am a trainee. According to my teacher, he says that to solve a problem we should go with steps to solve it like

1. Create Algorithm (optional)
2. Create a Datatable: By analyzing the problem, create main concepts in those problem as columns and the related issues in the main concept as rows.
3. Create a Flowchart based on the Datatable. (when creating flow chart, think that you are in that situation and design it in your brain)
4. By seeing the Flowchart, solve the problem.

These steps should always consider by a programmer if he/she wants to become a Software designer (not programmer). Because the above approach gives an efficient way of finding solution to a problem even the problem is small. According to him, this way of approach also works in real time scenario's.

My question is: Is this really an efficient way? please share also your thoughts.

Keeping beside my question I just want to share some thoughts of my teacher with you who is a good mentor for me.
