1.2 User Description
List the types of users who might be using the workplace. Provide a short description of the characteristics for types of the users on your list (e.g., a
child is someone with small hands; an engineer is someone with technical knowledge)
The user is an office staff worker. She is female and approximately 152 cm in height. She is proficient in the use of Microsoft Word, Excel and Oracle
Peoplesoft Enterprise. The user spends the majority of her time on work, behind a computer.
1.3 Tasks Analysis
Identify the primary tasks through which users interact with the workplace/product/system. Observe/interview the users and define the relevant % of
working time allocated to them during 1 week/1 month.
1.3.1. Tasks with or without use of computer
Tasks Working time [%]

1.3.3. Tasks with use of computer
Tasks Software name, version Working time [%]
1. Shared workspace of all the HR staff. Staff claims
for salaries and applications for vacation occurs
there. It is directly linked to the bursary.
Competency Core 7
2. Advertise vacancies (in-house) Google Chrome v48.0.2564
(Caribbean Jobs Online)
10
3. Prepare Word documents via Microsoft word. The
worker types memos, meeting minutes and job
letters.
Microsoft Office 2013 8
4. Shared workspace of the HR division. Persons that
respond to vacancy ads and apply for jobs are short
listed in the program as well as staff personal
information are stored here.
Oracle Peoplesoft Enterprise
v9.2

Identify the primary tasks through which users interact with the workstation. Choose two computer tasks for an in-depth description. For each task,
describe how a user would complete the task using the existing workstation. Descriptions with sufficient detail are those in which the reader can clearly
identify the following types of activities:
physical (e.g., press the button),
perceptual (e.g., read the signs/labels, hear the warning signs), and
Cognitive (e.g., decide which button to push, determine what is causing the problem).
Manipulation of HR documents – Utilizing Oracle Peoplesoft Enterprise 9.2, the user must physically press keyboard keys frequently, interpret
different fields within the software, and then determine what the field should be filled with. This is done with respect to human resource data, for the
University of the West Indies.
Advertising of in-house vacancies – Utilizing Google Chrome to access Caribbean Jobs Online, the user must physically press keyboard keys in
order to enter data onto the website. Profiles of the required candidates must be read from requested documents, and the layout as well as overall
format would be determined and posted by the user.
5. Dimension: Work space/ work surface/ layout/ work posture/ seating
6. Dimension: Environment (illumination, temperature, air flow, noise)
7. Dimension: Software
8. Dimension: Health/hazards
9. Dimension: Common
Use the example checklist given on project website (http://www2.sta.uwi.edu/~anikov/optm3041/projects/word-form-2-checklist.docx)
2.2 Workplace study
2.2.1. Collect data using the checklist from the workplace
2.2.2. Collect data using a lightmeter
3 Ergonomic analysis of workplace
3.1 Calculation of workplace hazard risks
Calculate using EXCEL sheet the workplace hazard risks for different dimensions using data gathered from assignment 2. Determine the average
values for each dimension in % [0,100] transforming the scale x∈[1,5] to y∈[0,100] by formulae y=(x-1)*25. The total health risk is the average risk
of all dimensions (1-8). Calculate the dissatisfaction dimension by the formulae dissatisfaction = 100-satisfaction. Present the results in a bar chart
(see below example bar chart). Use integer digits and colors as follows: dark green: 0-25%; light green: 26-50%; yellow: 51-75%; red: 76-100%
