What Is the SADRAT Cycle in Intelligence? Explained

SADRAT is the acronym English-language intelligence literature uses to summarise the life cycle of a human source: spot, assess, develop, recruit, handle, terminate. It appears in academic manuals, officers' memoirs and articles in the CIA's internal journal as a descriptive framework for HUMINT work.

This article explains the model at a conceptual and historical level — what each phase describes and what criticisms it has received — without going into specific tradecraft. Its interest, for anyone studying intelligence, lies in giving order to a process usually told anecdotally.

The phases of the model

Most of the literature agrees that the decisive phase is not recruitment but assessment: most identified candidates never reach the next stage, either because they lack the access assumed or because the risk is disproportionate.

The debate over motivations: from MICE to RASCLS

The classic model explaining why someone collaborates is MICE — money, ideology, compromise, ego — usually taught alongside SADRAT. In 2013, officer Randy Burkett published an influential article in Studies in Intelligence criticising it: MICE, he argued, is a catalogue of isolated motives, not a model of why a human relationship works. He proposed replacing it with RASCLS, based on Robert Cialdini's principles of social influence (reciprocity, authority, scarcity, commitment, liking, social proof).

That internal debate matters for understanding SADRAT's limits: these are descriptive, pedagogical frameworks, not laws. The history of intelligence is full of sources who volunteered without being spotted by anyone — the so-called walk-ins — a phenomenon the linear scheme does not capture well.

Criticisms of the model

• It is linear, whereas historical cases show discontinuous processes, with lapses and reactivations.
• It does not explain walk-ins, who in several services have provided the most valuable information of a given period.
• It can give a false sense of control: the Mitrokhin Archive and other sources document fabricated, doubled or uncontrolled sources.
• It centres on the officer rather than the source, whose personal risk — and eventual abandonment once the relationship ends — is the most debated ethical aspect.
• It was born in the Cold War, in a world without biometrics, social media or a permanent digital trail, factors that today radically alter the first two phases.

In the current context, authors such as Michael Warner note that digitally verifiable identity has made clandestine work enormously more costly: the same tools that make it easier to locate a person also make it easier to detect whoever approaches them.
