Basic Definitions Definition of terms: Usability, Efficiency

Computer-Human Interaction: A Model A model of computer-human interaction A useful framework for thinking about designing for efficiency

Strengths and Weaknesses: Human vs. Computer A model of the relative strengths and weaknesses of users vs. computer systems Another useful framework for thinking about designing for efficiency

Possible vs. Actual Efficiency An important distinction between the efficiency made possible by a user interface design, and the actual efficiency of users when using it A discussion of the factors other than user interface design that may impact actual efficiency

When Efficiency is Key Learn when efficiency is a key usability goal and when its a secondary goal.

Why Efficiency is Important A cost benefit analysis demonstrating how designing for efficiency will result in a significant, bottom line return on investment A useful reference for learning more about cost justifying usability in general

Measuring Efficiency: An Overview I high level overview of the three efficiency evaluation techniques to be covered A discussion of where in the development lifecycle these techniques can be applied

Modeling: Intro A high level introduction to the keystroke level modeling technique Useful references to the modeling literature A sample level of effort for the modeling technique

Modeling: Human Operators Definition of the basic human operators used in the keystroke level modeling technique

Modeling: System Operators Definition of some sample system operators that can be used in the keystroke level modeling technique

Modeling: Other Operators Description of some additional human operators that may be included in the keystroke level modeling technique

Modeling: Task Breakdown Structuring a model by breaking a task down into a hierarchy of steps, substeps and interactions

Modeling: Assigning Operators Building a model by assigning operators to interactions and capturing each instance of each operator as a tally

Modeling: Calculations Calculating the total task time in a model by adding up operator tallies, computing total times for each operator, and then summing across all operators for the total predicted task time

Modeling: Comparisons Calculations for comparing models of the same task on two different user interface designs

Modeling: Analyses Analyzing the sources of productivity losses predicted by models of two different user interfaces for the same task

Modeling: Project Summary Summarizing modeling data across tasks for a single development project

Modeling: Example 1 A demonstration of modeling a simple step in an ecommerce shopping task: traditional checkout

Modeling: Example 2 A demonstration of modeling a simple step in an ecommerce shopping task: checkout shortcut
