Perform a task analysis

Performing a Task Analysis Lecturer Performing a Task Analysis A task analysis breaks down the functions that a product or a system performs into a number of tasks or subtasks with the aim of describing how the product or system works. The objective of performing task analysis of a given product is to understand how the product works by determining the required inputs, methods and outputs, as well as determining the intentions or goals of the product in a bid to clearly understand the product (Fain, 2006). Task analysis begins with task identification, which involves the analysis of all user actions of the product. One can get information about task identification by observing people using the product (or recalling how the person uses the product) or from the product’s technical documentation (especially user manual). This is followed by task classification into initial setup, product use, troubleshooting and maintenance, which is followed by task prioritization. The final part of task analysis is the development of task scenarios or task sequence, which arranges product tasks into the way they operate (Fain, 2006). This paper develops task analysis for a mobile phone.
Goals
The primary goal of using a mobile phone is to communicate with other people having mobile phones by calling them, receiving calls from them, texting or receiving text messages from them. A mobile phone also stores date and time and it helps a person to know date and time. Other functions of the mobile phone include reminding a person about important activities, such as meeting, acting as an alarm to help someone to wake up as desired or perform a desired task at a given time and listening to songs stored in the mobile phone.
Task Prioritization
Task prioritization is based on the importance of the task. For instance, communicating is considered the primary goal of the mobile phone, and it is, therefore given first priority. Second priority tasks are secondary tasks while third priority tasks are tertiary and are not necessary.

Talking
Texting
