Reducing ambiguity and rework

Ambiguity in product specifications often leads to costly rework, missed deadlines, and frustration across teams. When requirements are vague, such as describing a product as “fast,” “modern,” or “user-friendly,” teams may interpret them differently, producing inconsistent results. A clear specification prevents this by replacing assumptions with measurable details. For instance, instead of stating that an app should load quickly, the spec can define a target load time of two seconds on standard mobile networks.

Precise wording and quantifiable metrics leave no room for misinterpretation. This approach helps engineers understand technical expectations, designers grasp usability standards, and testers verify compliance. Clarity at the specification stage reduces back-and-forth discussions later and prevents development from drifting away from intended outcomes.^[1]
