GTA: Groupware task analysis Modeling complexity

The task analysis methods discussed in this presentation stem from Human-Computer Interaction (HCI) and Ethnography (as applied for the design of Computer Supported Cooperative Work CSCW), different disciplines that often are considered conflicting approaches when applied to the same design problems. Both approaches have their strength and weakness, and an integration of them does add value to the early stages of design of cooperation technology. In order to develop an integrated method for groupware task analysis (GTA) a conceptual framework is presented that allows a systematic perspective on complex work phenomena. The framework features a triple focus, considering (a) people, (b) work, and (c) the situation. Integrating various task-modeling approaches requires vehicles for making design information explicit, for which an object oriented formalism will be suggested. GTA consists of a method and framework that have been developed during practical design exercises. Examples from some of these cases will illustrate our approach

Applying hierarchical task analysis to medication administration errors

Medication use in hospitals is a complex process and is dependent on the successful interaction of health professionals functioning within different disciplines. Errors can occur at any one of the five main stages of prescribing, documenting, dispensing or preparation, administering and monitoring. The responsibility for the error is often placed on the nurse, as she or he is the last person in the drug administration chain whilst more pressing underlying causal factors remain unresolved. This paper demonstrates how hierarchical task analysis can be used to model drug administration and then uses the systematic human error reduction and prediction approach to predict which errors are likely to occur. The paper also puts forward design solutions to mitigate these errors

Task analysis for error identification: Theory, method and validation

This paper presents the underlying theory of Task Analysis for Error Identification. The aim is to illustrate the development of a method that has been proposed for the evaluation of prototypical designs from the perspective of predicting human error. The paper presents the method applied to representative examples. The methodology is considered in terms of the various validation studies that have been conducted, and is discussed in the light of a specific case study

Cognitive Task Analysis

Boyle, E., Van Rosmalen, P., & Manea, M. (2013). Cognitive Task Analysis. CHERMUG Deliverable D14.Research methods and statistics are core competences across various disciplines but pose significant challenges for many students. The CHERMUG project aims to develop a digital game to support students in acquiring methodological and statistical expertise. A key issue that has to be addressed in developing a game is to identify the desired learning outcomes for students. This deliverable describes a cognitive task analysis which was carried out to identify the component cognitive skills, knowledge and competences that are required in developing a comprehensive and usable understanding of research methods and statistics.The present work was carried out as part of the CHERMUG project. This project is partially supported by the European Community under the Lifelong Learning Programme project nr. 519023-LLP-1-2011-1-UK-KA3-KA3MP.

Group Warfighting Task Analysis

Report analyzes the lowest level warfighting tasks from the Army publication Blueprint of the Battlefield, to determine how the successful performance of a specific task might be affected by terrain and features of a simulated battlefield

Development of a task analysis tool to facilitate user interface design

A good user interface is one that facilitates the user in carrying out his task. Such interfaces are difficult and costly to produce. The most important aspect in producing a good interface is the ability to communicate to the software designers what the user's task is. The Task Analysis Tool is a system for cooperative task analysis and specification of the user interface requirements. This tool is intended to serve as a guide to development of initial prototypes for user feedback
