  1. Lecture 11 Today’s class is a discussion in task analysis (modified in class)

  2. What is Task Analysis? • 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. Task analysis emerged from research in applied behavior analysis and still has considerable research in that area.

  3. Using your groups: • Let’s say you were asked to develop an improved interface at the Pegasus, what are the tasks to consider in approaching this problem? • Formulate the tasks required from start to finish • Analyse (justify) these tasks to determine if they are truly suitable

  4. Pegasus Task 1: • Analyze the current system • Interview and observe users • Observe the cognitive process of the current system • Document the information gathered • Design through the iterative process • Implementation • documentation

  5. Pegasus Task 2: Outline task – develop an improved interface • Define problem: improved interface at the pegasus reception (check in/out counter) • Defining the scope (data gathering) • Examine the existing system, and documentation if any • Gather data on the existing system • Interview users of the system • Questionnaire for customers to determine efficiency (e.g. time (length) for check-in or check-out) • Analysis • Generate reports with findings • Design • Proposed solution based on objectives • Develop prototype • Test • Implement • Go Live

  6. Pegasus Task 3: • Study current system: • Current documentation • Interview • Observation of current users • Survey conducted – clients • Determine the type of users: • Frequency of use • Response time • Determine requirements • Structure requirement – hardware • Types of user interface • Generate alternatives (e.g. touch screen) • Recommend best alternative • Design (prototyping – involve users in design) • Implementation: • Hardware and software installation • User training • Run parallel or Direct Conversion (“Cold Turkey”) – has highest risk of failure • Maintenance ALWAYS REMEMBER DOCUMENTATION

  7. Evaluation done after design is complete: • Survey among users on post implementation (stakeholders) • Determine if the system met the user requirements • Compare features of existing and proposed (inclusive of benchmarking proposed system) • Determine if system is efficient and reliable (response time, ergonomic concerns, interface) • Are there any new issues/concerns post implementation? • Technical & Operation (HRM) Feasibility
