THE FSLA™ FRAMEWORK PROCESS
FSLA™ follows a structured and methodological process.
FSLA™ was developed to provide a structured and evidence-based approach to credibility assessment, risk identification, and informed decision-making. Rather than relying on physiological measurements or mechanical testing, FSLA™ focuses exclusively on the analysis of communication. By examining a person's OWN words, we identify significant linguistic patterns, indicators, and areas requiring further consideration.
Every stage follows a consistent analytical framework, ensuring that conclusions are based on documented observations, objective reasoning, and verifiable linguistic evidence. The result is greater clarity, increased transparency, and actionable insight for legal professionals, investigators, organisations, and private clients.
OBJECTIVITY | CLARITY | INFORMED DECISIONS
The FSLA™ methodology comprises eight key stages. Contact us to find out more.
