Problem solving: Method: Analysis: Simplification: What is 'Decompose 
problem in subproblems' method

---

Fractionation:

---

In order to simplify the problem solving process, you often see that
you will reduce a problem in subproblems, and try to solve this
subproblems separately.

By breaking the problem into smaller pieces (subgoals) that are more
solvable), it might be easier to solve.

---

You try to get an overview of the problem, to distinguish the rather
independent parts of it, and then you separate these as much as 
possible.

---

For example, when you have to write a compiler, you might after some
thinking see that at least 3 different, rather independent parts might
be involved: a lexical analyzer, a syntax analyser and a semantic
analyser. A rather complex problem has now further been reduced to 3
more easy to solve subproblems.
