WHAT IS FLSA?

​FSLA™ combines forensic linguistic principles, structured methodology and documented reasoning to support objective credibility assessment.

At DDL, we developed FSLA™ (Forensic Statement & Linguistic Analysis) to bring greater clarity to complex situations. By applying a structured analytical framework, FSLA™ helps clients assess credibility, identify risk and make informed decisions based on evidence rather than assumption.

Objectivity
 

Independent analysis based on linguistic evidence, structured methodology and documented reasoning rather than assumption or personal opinion. 
Clarity


A systematic approach to examining statements, helping reveal patterns, inconsistencies and indicators that may otherwise be overlooked.   
Informed Decisions


 Actionable analytical insight that supports sound judgement when important decisions depend on the credibility of information. . 

HOW THE FSLA™ PROCESS WORKS

​FSLA™ follows a structured and methodological process.

We designed FSLA™ to assess credibility, identify risk and support informed decision-making. 

 

Each stage applies a consistent analytical framework, ensuring findings are based on documented observations, linguistic evidence and objective reasoning. ​By breaking statements down into their component elements, FSLA™ helps transform complex information into clear, actionable insight while maintaining transparency throughout. 

​

The methodology follows EIGHT key stages:
