Questions and answers

What must include interoperability considerations under AR 34-1?

Interoperability must be routinely considered and supported as part of Army planning, programming, budgeting, and execution (PPBE); force design; force structure; doctrine and policy; training; weapon systems and materiel requirements; research, development, and acquisition; information and data processes for assessment, monitoring, and evaluation (AME); materiel management; and logistics support processes. (paragraph 7)

What is the priority order for achieving interoperability?

The order of priority for achieving interoperability will be internal Army (multi-component), Joint, Inter-organizational and MN. The Army will address these priority areas simultaneouslynot sequentially. (paragraph 7)

What functional areas are Army interoperability priority focus areas?

The Armys interoperability PFAs comprise the following functional areas: communication and information systems (CIS)/information management (IM); intelligence, surveillance and reconnaissance (ISR) and intelligence fusion; digital fires; and sustainment. (paragraph 1-9)

How many levels of interoperability with unified action partners does the Army recognize?

To standardize interoperability planning, the Army recognizes four levels of interoperability with UAP: Level 0 (Not Interoperable), Level 1 (Deconflicted), Level 2 (Compatible), and Level 3 (Integrated). (paragraph 1-9)

What does Level 1 deconflicted interoperability require?

Requires alignment of capabilities and procedures to establish operational norms, enabling UAPs and the U.S. Army to complement each others operations. (paragraph 1-9)
