  1. TASK ANALYSIS The process of learning to identify user tasks

  2. Task analysis is the process of learning about users by

    identifying the route they take using the product and understanding in detail how they perform their tasks to achieve their intended goals PREPARED BY // GHIS
  3. How a task is accomplished, including a detailed description of

    both manual and mental activities involved in or required to perform a task – Task allocation – Element durations – Task frequency – Task complexity – Environmental conditions PREPARED BY // GHIS
  4. The purpose of Task Analysis ▪ What your user’s goals

    are? ▪ What user’s do to achieve their goals? ▪ What experiences user brings to the task ▪ How users are influenced by their environment ▪ How previous knowledge and experience effect how they think about their task PREPARED BY // GHIS
  5. When to use Task Analysis? ▪ Requirements gathers (Scoping) ▪

    Developing content strategy and site structure ▪ Wireframing and prototyping ▪ Performing usability testing PREPARED BY // GHIS
  6. Before you start Task Analysis ▪ Trigger ▪ Desired Outcome

    ▪ Base Knowledge ▪ Required Knowledge ▪ Artefacts PREPARED BY // GHIS
  7. Task Analysis techniques ▪ Hierarchical Task Analysis: Focused on decomposing

    a high-level task subtasks ▪ Cognitive Task Analysis: Focused on understanding tasks that requires decision- making, problem-solving, memory, attention and judgement PREPARED BY // GHIS

  11. Cognitive Task Analysis ▪ User Group – Actions performed by

    user – What does user do? ▪ System group – Actions carried out by the system – What does user see? PREPARED BY // GHIS
  12. ▪ Question group Unresolved questions associated with the task ▪

    Object | Information group Requirements of the user to carry out an action PREPARED BY // GHIS
  13. User System Question

  14. None
  15. Task Optimisation ▪ Eliminate unnecessary steps ▪ Automate repeated steps

    ▪ Optimise the process to help users achieve their goal at much higher speed PREPARED BY // GHIS
  16. Case Study PREPARED BY // GHIS

  17. User Story ▪ As a user, I want to send

    a text message to hospital’s system PREPARED BY // GHIS
  18. Task Flow 1. Open the messaging application on mobile phone.

    2. Enter the hospital system’s special number. 3. Move to the text input field. 4. Type the words “next patient”. 5. Check the spelling (because it needs to be precise for the system to accept it). 6. Hit the “send” button. 7. Exit the messaging application. PREPARED BY // GHIS
  19. None
  20. None
  21. None
  22. None

  24. None
  25. None
  26. User Story As a user I want to order Japanese

    Ramen with a side boiled egg to my current address in less than 30mins PREPARED BY // GHIS
  27. ▪ Trigger: ▪ Desired outcome: ▪ Base knowledge: ▪ Required

    knowledge: ▪ Artefacts: PREPARED BY // GHIS
  28. ▪ What prompts users to start their task? ▪ How

    users will know when the task is complete? ▪ What will the users be expected to know when starting the task? ▪ What the users actually need to know in order to complete the task? ▪ What tools or information do the users utilize during the course of the task? PREPARED BY // GHIS
  29. ▪ Trigger: Order Japanese ramen ▪ Desired outcome: Receive Ramen

    within 30mins ▪ Base knowledge: Japanese dishes ▪ Required knowledge: GrabFood app on the phone ▪ Artefacts: Smartphone, Internet connection PREPARED BY // GHIS
  30. Summary ▪ Task analysis must be backed by solid user

    research and domain knowledge while focusing on what user’s actual needs are ▪ Task analysis is not a one-off process. You can repeat it since Design Thinking is an iterative process that will eventually lead you back to the “define” stage at some point PREPARED BY // GHIS
