Facts about task inventories
-Typically involve surveys of job experts
-May be more than 100 tasks
-Often listed alphabetically under "duty" so that it's easier to search for specific task
Survey Design Steps
1. Background information
2. Structure of tasks
3. Determining the appropriate level of specificity
4. Selecting response options
5. Demographic data
Background information
(step 1 of Survey Design)
-Questions on survey typically written by analysts (using many sources of information):
--background materials (job description, training materials)
Structure of a task
(step 2 of Survey Design)
-Similar to FJA
-Action verb+ direct object+ additional qualifying statements
-i.e. "Call patient about scrip not picked up after 7 days"
-Statements put into survey and given to people to respond to statement in various ways
-Must be easily understandable to respondents (take vocab into account, allowed to use jargon if understood)
Determining the appropriate level of specificity
(step 3 of Survey Design)
-Rule of thumb: consider whether the task can be broken down into meaningful bits without referring to specific sequences of movement
-Depends on purpose of JA
--For performance appraisal, broad is okay
-- For training, more specific is better
Selecting response options
(step 4 of Survey Design)
-May measure the degree of involvement of incumbent on task, time spent on task, or importance of task on job
-Also can ask about consequences of error, difficulty to learn task, ability of others to cover for incumbent, and even satisfaction
-Way in which question is worded is very important
-Purpose of JA determines choice of scale
Demographic Data
(step 5 of Survey Design)
-Common to ask for background info about respondents as part of survey
-i.e. experience on job, location of job, age, sex, etc.
-Large, representative samples of informants should be used to make ratings of tasks
Data Analysis
-CODAP and WPSS were designed for computerized data analysis
-See pg. 55 for examples
