What is the best abstract problem solving process?

It is difficult to answer his question. Problems (and so their solutions) differ in nature, complexity, impact, continuity, urgency, and other parameters. A valid approach to solve one problem could not be valid for another. In some kinds of problems we can not even determine if a solving approach is correct or wrong, and should wait to see the final results to judge if the solution was good or not. But the logic process that may applicable could be preseted as the following (5D) Model:

1- Define: Understand the problem, the situations, the impact, the causes, ... everything you can understand about the problem, and especially the real cause (i.e the root cause)

2- Design: Build up the best feasible applicable solution that can get rid of the problem. it's cause, and it's impact with te minimum resources & cost

3- Do: Apply the solution

4- Direct: Manage the solution, evaluate it, correct if necessary

5- Develop: Learn to be better and well prepared for the next times

There are many Abstraction themes which involves induction of ideas or the synthesis of particular facts into one general theory about something as:

1. Compression
2. Instantiation
3. Material process
4. Ontological status
5. Physicality
6. Referencing and referring
7. Simplification and ordering
8. Thought processes

all of them are state of mind and a way of thinking to generate ideas, solutions and problem solving.

Identify the source of problem,

Note down the causes,

List all possible ways,

Check the feasibility and consequences,

Draw a road map using CPM & PERT.

Attack the problem and resolve it.

problem can be solve by the following ways

identify the problem first and make more then alternatives.compare all the possible alternatives with the problem while looking at cost and time...select on of the most suitable solution among the alternatives and implement it.
