Lecture 9 'Cognitive Work Analysis' Flashcards
What is the difference between NORMATIVE, DESCRIPTIVE and FORMATIVE analysis?
Normative = analysis of how user and system ideally SHOULD work cog task analysis
Descriptive = analysis of how user and system actually DO work cog task analysis
Formative = analysis of how user and system potentially COULD work cognitive work analysis
Q. 42. What is the best description of the difference between cognitive work analysis and cognitive task analysis?
CWA = constraints that shape people’s cognitive activities,
CTA = focuses on describing people’s cognitive activities
(Q 43). Which of the following is NOT true about the phase of cognitive work analysis that is named?
a. Strategies analysis informs us about ways people perform control tasks
b. Social and organisational analysis informs us about the purposes, values, functions, and
physical aspects of a system.
c. Worker competencies analysis informs us about the skills, expertise, and other cognitive
descriptions of task performance.
d. Control task analysis tells us about what needs to be done for the work domain to function
NOT CORRECT = (b) Social and organisational analysis informs us about the purposes, values, functions, and
physical aspects of a system.
(Q 46) How was cognitive work analysis used for Project Wedgetail (AEW&C) tender evaluation by Naikar and Sanderson (2001)?
Work domain analysis was used to guide the assessments performed by tender evaluation working groups of different AEW&C design options
(Q 3.) What is a “formative” analysis of human interaction with a technical system?
An analysis of constraints that should be satisfied if human and system are to work in a new, desired, way.
What are the five phases of analysis?
> Work domain analysis (purpose/structure)
> Control task analysis
(what needs to be done)
> Strategies analysis
(ways that control tasks can be done)
> Social-Org analysis
(who carries out work/shared)
> Worker Competencies analysis (kinds of mental processing supported)
What is the EID NOT based on?
Task analysis or operator mental model
Work domain analysis determines what ________ and ________ to display
constraints
affordances
What are the different kinds of relationships to show between system functions and structures in work domain analysis?
Means-ends
Topographic
Part-whole
Work domain analysis in “abstraction hierarchy” forms what?
information requirements and constraints
The KAIST NPP EID displays helped participants by doing what? How did it impact performance?
Adding the higher levels of information from the Work Domain Analysis
Adding graphics showing relationships improves performance
Neleen Naibar used cognitive work analysis to work out how many people were needed in the Project Wedgetail, how many were there?
7 people who are multi-skilled
