“…Some of the initial CLA design features parallel those described in previous systems in the literature; for example, the CALA system (Glass et al, 1991) includes flexible layout design (drawing/moving/ resizing/deleting/name elements); a time‐event list can be produced by the link analyzer system (Thorstensson et al, 2005); and the fast‐event‐recording method is a feature of the FIT system (Held et al, 1999). For example, the link diagram output is not available in either the CALA and link analyzer systems.…”

“…The traditional LA method continues to be a very popular task analysis method; however, the manual data recording and result‐generating processes are extremely labor intensive and time consuming (“the manual process of keeping a tally and counting links becomes prohibitively time‐consuming”; Glass, Zaloom, & Gates, 1991). The two outputs give limited data for 1) how many times the link occurs in link table and 2) graphical information in link diagram, which are not easily quantifiable.…”

“…To address these limitations, some researchers have developed computerized systems, such as the computer‐aided link analysis (CALA) system (Glass et al, 1991), link analyzer system (Thorstensson, Axelsson, Morin, & Jenvald, 2005), and flexible interface technique (FIT) system (Held, 1999; Held, Bruesch, Krueger, & Pasch, 1999; Held & Manser, 2005). These all have limitations in either data capture and/or analysis.…”

Link analysis (LA) is a popular ergonomic tool for studying and improving the layout of workspaces. It uses a data (event) recording method to input interactions of human behavior with their environment. The traditional “pen and paper'' method of LA is cumbersome, time consuming, and gives limited outputs. To address these limitations, the computerized link analysis (CLA) system was developed and tested in laboratory and real‐world environments. CLA offers an integrated task analysis tool, including traditional LA functions (layout, event recording) with more detail for operator activities, time‐motion functions, and multioperator data recording. As well as the conventional LA results (link diagrams and link tables), there are additional outputs for time‐event lists (start/end time, duration, chronology, additional notes, importance, and operator ID), and processed link diagrams with the link direction and frequency. © 2012 Wiley Periodicals, Inc.

“…Haygood et al (1964) mentioned that it is possible to analyse tasks which consist of only several hundred steps with pen and paper, however it would be almost impossible when dealing with a task with thousands or more steps. 'The manual process of keeping a tally and counting links becomes prohibitively time-consuming' (Glass, Zaloom & Gates, 1991). This also leads to the difficulty of drawing an immense schematic link diagram for large system.…”

Motivation-Link Analysis (LA) is a method to study relationships of elements within a system, and it is also used as a data recording method of Naturalistic Decision Making (NDM), e.g. capturing staff movements. However LA has limitations, such as time-consuming data recording and results generating processes. Research approach-Computerised Link Analysis (CLA) system is being developed and tested by computerising template generating, real-time event recording and data analysing processes. Design-The first version of system has been accomplished and its description is included to demonstrate its versatility. Research limitations-This system is still at an early prototype stage and improvements and tests need to be conducted. Value-CLA is the first system which is designed specially for healthcare domain and has proven to save plenty of time compared to manual method. Take away message-CLA system is able to offer analysts an efficient and effective tool to perform LA.

“…As techniques develop many achievements of simplifying the method of LA have been documented, such as Computer-Aided Link Analysis system (Glass, Zaloom & Gates, 1991), Link Analyzer system (Thorstensson, Axelsson, Morin & Jenvald, 2005), etc. However, none are able to either capture and analyse real-time data effectively and efficiently, or were designed especially for use in the healthcare industry.…”
