A Functional Needs Analysis (FNA) assesses current and future capabilities to meet the military objectives of the scenarios chosen in the Functional Area Analysis (FAA) and is an output of the Capabilities Based Assessment (CBA). Using military scenarios, the FNA assesses whether or not an inability to achieve a desired effect exists to determine if there is a capability gap. The FNA also identifies any capabilities that have overlaps or redundancies which allows for streamlining efforts. Below is the JCIDS process map and where the FNA fits in the the CBA.

JCIDS Analysis Flow

A Functional Needs Analysis (FNA) should:

  1. Describe the capability gaps in terms of the scenarios assessed and the effects on achieving the relevant military objectives
  2. Assess the impact of the capability gaps
  3. Characterize capability gaps
    • Proficiency (inability to achieve the relevant effect in particular conditions);
    • Sufficiency (ability to achieve the effect but inability to bring the needed force to bear due to force shortages or other commitments);
    • Lack of existing capability;
    • Need for recapitalization due to aging of an existing capability;
  4. List the gaps that should be address or conclude that no pressing gaps exist.

The next step is the Functional Solutions Analysis (FSA)


  • The current CJCSI 3170.01G does not reference an FNA.  It rolls it up under a Capabilities Based Assessment (CBA).  You have to view previous versions of the 3170 to get a description of a FNA.
