An IT department is under pressure to cut costs. As a result, the quality of services has started to suffer. What imbalance does this represent?

Excessive focus on quality would mean over-investing in quality improvements at the expense of cost efficiency, which is the inverse of the scenario described.

Excessively reactive describes an organization that only responds to failures after they occur rather than preventing them proactively, which is unrelated to a cost-versus-quality imbalance.

Excessively proactive describes over-investment in preventive measures before issues arise, not a scenario where cost reduction degrades service quality.

ITIL Service Strategy requires maintaining a balance between cost efficiency and service quality; when cost reduction becomes the dominant priority at the expense of quality, it is classified as an excessive focus on cost. This imbalance is a recognized anti-pattern in service management where financial pressure overrides the obligation to deliver value.
