Tools

Hierarchical Task Analysis (HTA) Tool

Traditionally, predictive forms of task analysis were performed through the onerous use of paper and pencil. The products of the analysis normally required some form of lengthy manual conversion before they could be applied to the particular system-related issues in question. Furthermore, there was no HTA tool freely available or deemed generally acceptable for UK Military use. The HTA Tool has been designed to overcome these historical limitations.

A Literature review has been conducted and a questionnaire has been developed for use in interviews to establish which types of task analysis are used, what the task analysis output is used for, how the task analysis is undertaken, what tools are used etc. View a summary of the report. This information was used in the development of the HFI DTC's HTA software tool.

Cognitive Task Analysis

A literature review of Cognitive Task Analysis (CTA) methods has been conducted, methods were reviewed in terms of applicability to the CADMID development stages. Interviews have also been carried out to establish which types of CTA are used, how the output is used etc. These revealed that no software CTA tools, or the term CTA are currently in use, in the military domain and it is clear that the three services take differing views on CTA. Because it doesn't appear to be extensively used in the military domain, contacts external to the armed forces were also approached. View a summary of the report

Cognitive Work Analysis (CWA) Tool

Cognitive Work Analysis (CWA) is a structured framework for considering the analysis, design and evaluation of complex sociotechnical systems. The framework is particularly suitable for the analysis and design of first-of-a-kind systems, or systems undergoing revolutionary change, such as digitisation. The framework leads the analyst to consider the environment the task takes place within, and the effect of the imposed constraints on the system’s ability to perform its purpose. The framework guides the analyst through the process of answering the question of why the system exists; what activities are conducted within the domain as well as how this activity is achieved and who is performing it. The framework has been applied to a number of military and non-military domains.

Event Analysis of Systemic Teamwork (EAST)

The EAST methodology was developed specifically for the analysis of collaborative activity in complex socio-technical systems. EAST provides practitioners with a framework of integrated human factors methods that permits an exhaustive analysis of teamwork during command and control activity, including the tasks performed, the level of collaboration between team members, the communications between team members and the technology used to mediate them, the situation awareness and workload of the team and its members, and the structure of the network of agents involved. The EAST output allows conclusions to be drawn on the efficiency and effectiveness of the command and control system analysed.

Workload Error, Situation awareness, Teamwork and Time (WESTT)

WESTT is a novel software tool that supports field observation and analysis of command and control or network-enabled scenarios. WESTT also provides a means by which data collected in the field can be represented in an appropriate manner and supports the application of objective measures of human performance to those data.

Rapid Assessment of Tasks and Context (RATaC)

Rapid Assessment of Tasks and Context (RATaC): Methodological Development The Rapid Assessment of Tasks and Context (RATaC; Stone, 2004) methodology is a Technology-Based Training (TBT) system needs analysis approach that supports the quick and early capture of salient human factors aspects of tasks and contexts in order to inform the development of TBT systems. RATaC was developed primarily to provide training system designers with a quick, simple and low cost approach to identifying training system needs in terms of the tasks, contexts, environments and fidelity level required.

HFI Federate and HF tool Evaluation

The Human Factors Integration (HFI) Federate and HF Administrator Tool were originally developed from HFI DTC research into the use of synthetic environments to support HFI.  The purpose of the HFI Federate and HF Administrator Tool was to support the measurement and collection of human factors performance data of tasks carried out in a synthetic environment.

Prototype Technology Appropriateness Guidelines (TAG) Tool

The goal of this research project is to set up and maintain an Internet hosted repository of HF “Technology Appropriateness” guidance material for current and emerging technologies for use by military contractors and IPTs.

Technology Appropriateness Guidelines (TAG) Tool The goal of this research theme was to set up and maintain an Internet hosted repository of Human Factors (HF) “Technology Appropriateness” guidance material for current and emerging technologies. An Internet hosted Technology Appropriateness Guidelines (TAG) Tool with a database of technologies was created to provide HF practitioners and Integrated Project Teams (IPTs) with information on current and emerging technologies. The TAG Tool was designed to be a repository for new and current technology information along with associated HF guidance and reference material.

Trials

Mission Planning System (MPS) Analysis

The Human Factors Integration Defence Technology Centre (HFI DTC) conducted a range of human factors analyses on the process of electronic mission planning in order to inform the development of future electronic mission planning systems.
