Hierarchical Task Analysis (HTA)
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.
Hierarchical Task Analysis: Developments, Applications and Extensions Review of the Hierarchical Task Analysis technique.
HTA: The development and use of tools for Hierarchical Task Analysis in the Armed Forces and elsewhere This report covers the recent past, and current usage of the HTA technique in, and for, the UK Armed forces. It considers the reasons why an HTA should be (or may have been) conducted. It then considers current and recent practices in a selection of Governmental and other organisations – both at home and abroad.
Creating interoperability between the Hierarchical Task Analysis and the Cognitive Work Analysis Tools This document addresses the HTA (Hierarchical Task Analysis) tool and the CWA (Cognitive Work Analysis) tool to establish if a link between these two tools, allowing data to be passed between them, would be appropriate and beneficial.
Cognitive Task Analysis (CTA)
Cognitive Task Analysis: Current use and practice in the UK Armed Forces and Elsewhere This report is concerned with Cognitive Task Analysis (CTA). It covers the origins, growth, and diversity of CTA as an activity, current practice in the UK Armed Forces and civilian operations, reviews an extensive range of archive material and draws a number of conclusions as to the best practice.
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.
A Review of the Event Analysis of Systemic Teamwork Methodology This report describes a review of the Event Analysis for Systemic Teamwork (EAST) methodology that was used to analyse C4i activity in the rail, air traffic control, energy distribution, military, police, fire service and naval domains. The EAST methodology was specifically designed for the analysis of collaborative activity complex socio-technical systems.
EAST Methodology for Air Traffic Control Report The EAST methodology is used to derive results from five air traffic control scenarios observed live. The results of the individual EAST analysis methods provide multiple perspectives on key Command & Control, Communications, Computers and Intelligence (C4I) constructs.
EAST Methodology for Railway Data: Protection Scenario This report uses the EAST methodology to present results and analysis of a scenario drawn from the Railway industry. The scenario involves multiple distributed parties engaged in the task of setting up a ‘possession’ for a stretch of track in order that emergency engineering works can take place.
Report on Results of EAST Methodology for Railway Data: Possession Scenario This report uses the EAST methodology to present results and analysis of a scenario drawn from the Railway industry. The scenario involves multiple distributed parties engaged in the task of setting up an engineering possession on a stretch of track.
EAST Methodology for Railway Data: Emergency Possession Scenario This report uses the EAST methodology to present results and analysis of a scenario drawn from the Railway industry. The scenario involves multiple distributed parties engaged in the task of setting up a ‘possession’ for a stretch of track in order that emergency engineering works can take place.
Report on Results of EAST Methodology for Railway Data: Hand Back Possession Scenario This report uses the EAST methodology to present results and analysis of a scenario drawn from the Railway industry. The scenario involves multiple distributed parties engaged in the task of handing back a ‘possession’ for a stretch of track previously taken for the purposes of engineering work.
Human Factors Design Methods
Human Factors Design & Evaluation Methods Review The overall aim of this work package was to review and evaluate HF methods and techniques suitable for use in the design and evaluation process of future C4 systems. Each HF technique is described and reviewed using a set of pre-determined methods evaluation criteria and the output of the review acts as a guide for HF practitioners in the selection and use of appropriate HF techniques.
Human Factors Design Methods Review This report contains a review of human factors (HF) design methods. The overall aim of this work package was to review and evaluate HF methods and techniques that might be suitable for use in the C4I systems design lifecycle. This document is intended to act as a guide for HF practitioners in the selection and use of appropriate HF techniques.
