 SISO-REF-061-2015Final Report for the Human Performance Markup Language Study Group
The findings established (1) a direct need for a standard that represents diagnostic human performance within simulations that is not addressed through current standards; (2) the Human Performance Markup Language offers a standardized diagnostic representation of human performance within simulations; and (3) there is broad support within the industry and across the Services within the DoD for HPML as a standard.

SISO-REF-060-2016: Final Report for the Parallel and Distributed Modeling and Simulation Standing Study Group
This group engaged in parallel and distributed modeling and simulation community outreach and education efforts at SIWs through tutorials, presenting papers, and technical discussions.

SISO-REF-058-2015:  Final Report for the Architecture Neutral Data Exchange Model Study Group
The primary result produced by this study group is the recognition that there is an unsatisfied need for an architecture independent representation of data exchange models that are both easy for people to read and understand and yet still rigorous enough to support the generation of architecture specific data exchange models for the individual architectures plus the gateways or translators that link them together. Unfortunately, there is currently no obviously best representational technology available to implement an ANDEM that is easier to understand than the currently available architecture specific representations.  The study group does not recommend any further action by SISO at this time. While there is a need for a more understandable and efficient way to express the information that needs to be exchanged by federates in a distributed simulation, research needs to be performed before any particular approach can be considered for standardization.

SISO-REF-057-2015: Layered Simulation Architecture Study Group Final Report
This is the final report of the Layered Simulation Architecture (LSA) Study Group (SG).  The SG began its operations in 2012 with the purpose to apply current thinking on network centric interoperability and open systems architecture to modeling and simulation. Technical findings included: 1) Data Distribution Service (DDS) can run over internet; 2) LSA architecture can be built in a real project; 3) DDS Interoperability Wire Protocol (DDSI) allow a simulation to interoperate with different DDS vendors; 4) Protocol Application Programming Interfaces should be abstracted as proposed by FACE 2.0 C137 from The Open Group; and 5) System interoperability involves strong interface management. The SG recommended the creation of a Product Development Group to develop a SISO Standard based on the concepts proposed in the report.

SISO-REF-051-2014:  WebLVC Study Group Final Report
This is the final report of the WebLVC Study Group (SG).  The SG's identified several good technical approaches including:  1) Representing simulation semantics in JSON messages; 2) Auto-generating WebLVC messags from an HLA FOM; and 3) Sending WebLVC messages over WebSockets.  Additionally, the SG found that performance of WebLVC is sufficient for the needs of many M&S applications, it is possible to use WebLVC in native (non-browser-based) applications, and the WebLVC concept lends itself to client-specific interest-management techniques.

SISO-REF-043-2012Reuse and Interoperation of Environmental Data and Processes (RIEDP) SG Final Report
The 29 month study group effort focused on three sub-areas: LVC Environment Needs, the Fall 2009 SIW Special Workshop, and the Harmonization Objective. The SG recommends continuing with Product Nominations for two products - an Environmental Data Model Foundations product which would be a Guidance document (to include a Reference Process Model(RPM), and a Referenca Abstract Data Model (RADM, both of which were addressed by the RIEDP SG), and an Environmental Detailed Features Description product which would be a SISO Standard product. 

SISO-REF-042-2013UCATT Study Group Final Report
The Urban Combat Advanced Training Technologies (UCATT) Study Group (SG) Final Report provides an overview of activities spanning 2009 - 2012.  The Technical Co-operation Agreement between the NATO Modelling and Simulation Group (NMSG) and SISO, formalized the individual participation by NMSG members in the SG. This document would not have been possible without the work produced by former NATO Modeling and Simulation Task Groups MSG-032 and MSG-063, and the current support of MSG-099. Membership includes representatives from Finland, France, Germany, Netherlands, New Zealand, Spain, Sweden, Switzerland, Turkey, United Kingdom, and the United States. The SG decided that based on the numbers and complexity of potential products to be standardized in support of live instrumentation interoperability to follow a multi-staged process to implement the multiple interface standards.

SISO-REF-028-2011: Distributed Debrief Control Protocol (DDCP) Study Group Final Report
The results of the 2008 DDCP Study Group survey reflected a positive reaction towards developing a DDCP standard. The opinion was shared across a large cross section of distributed simulation practitioners including U.S. and international responses. The original recommendation of the report was to stand up a Product Development Group (PDG) for the purposes of creating a distributed debrief interoperability standard. Subsequent diminishing Study Group meeting attendance resulted in a delay. Renewed interest in 2011 has resulted in the creation of the Distributed Debrief Control Architecture (DDCA) PDG. A multi-revision approach is recommended for developing the standard so that benefits can be quickly realized. Ideally the initial standard would focus on the record and playback capabilities, which provide the backbone for the distributed debrief capability. Additional standard revisions would roll out with enhancements organized through the PDG. The experiences and lessons learned from other SISO product standardization groups would be leveraged in order to maximize benefit and minimize side effects caused by a multi-revision process.
