If nothing at all related to the work your product is currently automating is currently being done, there is a good chance you are building a product that nobody needs. Good products are always driven by real user needs. (Deborah J. Mayhew)
Task analysis is the analysis of how a task is accomplished, including a detailed description of both manual and mental activities, task and element durations, task frequency, task allocation, task complexity, environmental conditions, necessary clothing and equipment, and any other unique factors involved in or required for one or more people to perform a given task.
Two types of Task Analysis:
Hierarchical task analysis (manual activities)
Cognitive task analysis (mental activities)
Why Task Analysis?
Wherever automation exists, there is need for a methodological description of the task so that it is user friendly.
Helps you discover how your product is being used and were it breaks down
Do no conduct too many task analysis without stoping and taking a step back to digest the information.
Do not be a perfectionist, focus on the general process.
Reasons Why Task Analysis is important:
Minimizing the risk of injury
Assisting with pre-employment health checks
Have a better understanding of safety training
Helps to ifentify alternate duties for employees
Ensure that employees have a clear understanding of requirements and productivity
