Signal Decay Window

Signal Decay Window treats every competitive data point as perishable. A rival's ad spend snapshot, a keyword ranking shift, or a tender award has a useful life measured in days or weeks, not quarters. Agencies that timestamp intelligence and set a decision clock around it win pitches with fresh evidence; those that archive it into quarterly decks present stale findings as current strategy. The framework asks three questions for any signal: when was it captured, how fast does this category move, and what decision does it need to trigger before it expires. A concrete case: government procurement awards indexed across 194 countries and 1.4 million contracts move on published tender cycles, so a bid team that reviews award data weekly catches recompete windows that a quarterly review misses entirely. The same logic applies to display ad creative tracked across 145 ad networks, where a competitor's campaign rotation can shift inside a single flight.
