Testing Steps
The following 11 steps were developed based upon the methodologies and ideas of Kieras and Olson-Olson and describe the proper approach to calculate the time it takes to complete a task by using a computer interface and hardware.
Step 1--Obtain a working prototype of computer interface or a step by step operational description of a task.
Step 2--Identify the goals or the desired outcome of work .
Step 3--For each of these goals, find subgoals or tasks that achieve the main goals.
Step 4--Identify methods to main goals and all subgoals.
Step 5--Convert description of methods to pseudo-code (the terminology that is described above).
Step 6--State any and all assumptions used in the making of pseudo-code and goals.
Step 7--Determine appropriate mental or keystroke operators for each step.
Step 8--Assign time values to mental or keystroke operators.
Step 9--Add up execution times for operators.
Step 10-Adjust total time of task to be sensitive by age of expected.
Age Time Adjustment Multiplier (Multiply task time by this value) Use as is 30–40 ??? 40–55 By 1.4 55–60 By 1.7 > 65 By 2.2Step 11-Verify validity of results

Famous quotes containing the words testing and/or steps:
“No testing has overtaken you that is not common to everyone. God is faithful, and he will not let you be tested beyond your strength, but with the testing he will also provide the way out so that you may be able to endure it.”
—Bible: New Testament, 1 Corinthians 10:13.
“And, beholding in many souls the traits of the divine beauty, and separating in each soul that which is divine from the taint which it has contracted in the world, the lover ascends to the highest beauty, to the love and knowledge of the Divinity, by steps on this ladder of created souls.”
—Ralph Waldo Emerson (1803–1882)
