Question 2

Which of the following is the primary goal of the 'divide and conquer' strategy, a classic form of problem decomposition?

Accepted Answer

Answer

To assign different parts of a problem to different individuals.

Answer

To increase the difficulty of a problem to test problem-solving skills.

Answer

To solve the easiest part of the problem first to build momentum.

Question 3

In project management, the creation of a Work Breakdown Structure (WBS) is a formal application of which problem-solving strategy?

Accepted Answer

Problem Decomposition

Answer

Question 4

A software development team successfully decomposes a large application into ten independent modules. They assign each module to a different developer who codes and tests it perfectly in isolation. However, when they try to integrate the modules, the entire system fails. What critical step of problem decomposition was most likely overlooked?

Accepted Answer

Defining the dependencies and interfaces between sub-problems.

Answer

Ensuring the sub-problems were small enough.

Answer

Assigning tasks based on developer skill.

Answer

Using a top-down instead of a bottom-up decomposition approach.

Question 5

Which of the following is NOT a recognized benefit of applying problem decomposition?

Accepted Answer

It guarantees that an optimal solution for the overall problem will be found.

Answer

It reduces cognitive load and makes complex problems more manageable. [3]

Answer

It facilitates parallel work, allowing multiple people to solve different sub-problems simultaneously. [3, 4]

Answer

It simplifies debugging and troubleshooting by isolating issues within smaller components. [3]

Question 6
