Suppose you need to analyze a procedure to change a tire of a car. Inputs to the procedural analysis could look like this:

The output of procedural analysis could capture the summary and detailed steps, as follows:

A. Prepare phase B. Remove phase C. Replace phase
 * 1) Identify a safe place to park your car to change your tire
 * 2) Prevent the vehicle from moving
 * 3) Open trunk and determine your plan
 * 4) Take safety precautions
 * 5) Prepare for removal of flat tire
 * 1) jack until it is supporting (but not lifting) the car
 * 2) Loosen the nuts by turning counter clockwise
 * 3) Pump or crank the jack
 * 4) Remove the nuts
 * 5) Remove the tire
 * 1) Place the spare tire on the hub
 * 2) Tighten the nuts
 * 3) Lower the car until the tire slightly bears the weight of the car
 * 4) Tighten the nuts again
 * 5) Lower the car to the ground fully
 * 6) Place flat tire, jack and other supplies in storage compartment

Prepare Phase

1) Identify a safe place to park your car to change your tire. (Decision)   a. You need a solid, level surface that will keep the car from rolling.     b. If you are in moving traffic, park as far from traffic as possible and turn on your emergency flashers (hazard lights).     c. Avoid soft ground and hills. 2) Prevent the vehicle from moving. a. Turn off the vehicle. b. Apply the parking brake and put car into "Park" position. c. If you have a standard (manual) transmission, put your vehicle in first or reverse. 3) Open trunk and determine your plan. (Decision)   a. What safety items are in the trunk (flashlights, caution signs, tire inflator, WD-40)?    b. Are you in moving traffic?    c. What side of the car is the flat on?      d. Is it day, dusk, or night time?    e. Are there other passengers in the car?    f. What type of jack is it?    g. Where does the jack get placed? 4) Take safety precautions. a. Prevent the car from moving by placing a heavy object (such as a rock, concrete, or a spare wheel) in front of the front and back tires. b. Use caution signs or flashlights if available. 5) Prepare for removal of flat tire.   a. Remove the spare tire, jack, and lug wrench from their storage compartment.    b. Determine placement of jack. (Decision)        i. Ensure that the jack is in contact with the metal portion of your car's frame.        ii. If you're not sure about the right place to put the jack, check your owner's manual.        iii.For most old cars that have a frame, you place the jack on one of the beams of the frame just behind the front tire or in front of the rear tire.     c. Place the jack under the frame near the tire that you are going to change.    d. As a precaution, place the spare tire under the body of the car near the jack and at a safe enough distance as to not interfere or potentially hit the jack when it is being placed or retrieved.
