Why good design reduces maintenance cost in Software Engineering - Quick Recap

Recall & Review

beginner

What is one main reason good design reduces maintenance cost?

Good design makes software easier to understand and change, which lowers the time and effort needed for maintenance.

beginner

How does modular design help reduce maintenance cost?

Modular design breaks software into smaller parts, so fixing or updating one part does not affect others, making maintenance simpler and cheaper.

beginner

Why does good documentation lower maintenance cost?

Good documentation helps developers quickly understand the system, reducing mistakes and speeding up fixes or improvements.

beginner

What role does code readability play in maintenance cost?

Readable code is easier to follow and change, which reduces the chance of errors and the time needed for maintenance.

intermediate

How does good design prevent costly bugs during maintenance?

Good design includes clear structure and testing, which helps catch problems early and avoid expensive fixes later.

Which of the following is a benefit of good software design for maintenance?

A Easier to understand and modify

B More complex to change

C Requires more documentation

D Increases maintenance time

Good design makes software easier to understand and modify, reducing maintenance effort.

What does modular design do to help maintenance?

A Breaks software into smaller parts

B Removes documentation

C Combines all code into one file

D Makes code harder to read

Modular design breaks software into smaller parts, making it easier to fix or update specific areas.

Why is good documentation important for maintenance?

A It confuses developers

B It helps developers understand the system quickly

C It increases bugs

D It slows down understanding

Good documentation helps developers understand the system quickly, reducing errors and speeding up maintenance.

How does readable code affect maintenance cost?

A Has no effect

B Makes code harder to change

C Increases errors and time

D Reduces errors and time needed

Readable code reduces errors and the time needed to make changes, lowering maintenance cost.

Good design helps prevent costly bugs by:

A Ignoring testing

B Using unclear structure

C Including clear structure and testing

D Making code complex

Good design includes clear structure and testing, which helps catch problems early and avoid expensive fixes.

Explain how good software design can reduce the cost of maintenance.

Think about how design affects understanding, changes, and errors.
