Problem

Process visibility
System structure

Description

Tends to degrade as new increments are added unless time is spent on refactoring
Managers need regular deliverables to measure progress but developing quickly makes documentation costly

Correct Answer

(1) Process visibility,Managers need regular deliverables to measure progress but developing quickly makes documentation costly
(2) System structure,Tends to degrade as new increments are added unless time is spent on refactoring

Explanation

The two management problems with incremental development are: (1) the process is not visible — managers need regular deliverables but producing documents for every version is not cost-effective; and (2) system structure tends to degrade as increments are added, making further changes increasingly difficult and costly.
