__Project 7.1.2- Test Criteria and Method__ Problem Statement Justified: Athletes need to wear different pairs of shoes while walking on any other surface other than a playing field; otherwise their spikes/cleats become dull or damaged. Our solution to this problem is to provide athletes with a shoe cover that fits on their cleats to protect their spikes from wearing out. This solution reduces the issue of having to frequently purchase cleats. The solution also helps the athlete because they do not need to bring an extra pair of shoes. The material the covers will be made out of is plastic which ensures a clean snap on to the cleats to makes the process a lot of quicker and easier for our customers. Economically this product ensures a longer last. Our solution can be sold separately or with a specific type of cleat shoe. Advertisement for both the cleat shoe and cover will increase if sold together since the two products work hand in hand. Our group has reached the final steps to perfecting our prototype. In order to make sure our problem has been corrected, we will need to create a test with multiple parts to evaluate our list of criterion. Some of the data that we can assess in our test include: making sure we have made a solution to the problem, verify that our design matches each of our critera and the overall performance of our prototype.

In order to measure the effectiveness of our design solution, the method of testing that we will use is both qualitative and quantitative. The criterion that our group will test our design off of include: appearance, effectiveness of design, durability, minimum effort/higher impact, material cost, features (appealing to customer), weight, safety, and ease of use (practicality), weight capacity. To complete the test on our designed cleat covers a team member will be used in making appropriate use of our prototype.

Team Member Names: Joey Maiorana, Joe Schneider, Nilu Faiz

Testing Date: April 7, 2009 (Subject to change)

Testing Location: Tile floor, asphalt

Purpose: To assess the quality and performance of our cleat cover, we will need to have a team member or any other individual slip on the covers over their cleats and walk on different surfaces.

Initial Conditions: Prototype (cleat covers) must be completed and dimensioned according to the cleat shoe.

Materials: shoe, cleat covers, data assessment sheets, pencil, calculator (if needed)

Pass or Fail Criteria: The cleat covers must be able to quickly and easily slip on over the shoe. Also, the covers must securely fit over the shoe and the spikes must be protected from external surfaces and not be hazardous in any way.

Procedure: A team member will wear the cleats. Then, he/she will need to place the designed cleat covers under their cleats. This process should be done with ease and the covers should be able to stay connected to the bottom of the shoe while walking. Then, the individual will be allowed to walk around on the asphalt without any trouble. After this procedure is complete, the team members will evaluate the prototype, checking off each of the criteria previously listed in a data chart.

Safety Considerations: Safety is the most important part of our testing procedure. We would like to prevent creating any additional problems that do not already exist prior to the development of our prototype. The individual will be given complete responsibility in handling the designed product. The prototype’s safety (one of the criteria) will prevent the team members from injury or hazards. Also, the prototype’s material should not damage the track field. The highest concerns of safety is the cover breaking under the pressure or the covers slipping while walking.

Data: The size and weight of the cleat covers will be recorded using ounces and centimeters (quantitative). Each of the criteria will then be categorized as either pass or fail (qualitative).

Data Collection Graph or Sheet: A pass or fail check list of each of the criteria will be listed in a table. [See attached]

Instructor Comments & Signature:

Result: The prototype will be checked off as either pass or fail in each of the categories and be graded overall on appearance and performance.

Project 7.2.1 Writing the Test Procedure__** Aspects being tested: Safety: Is it slippery? Is the cleat still balanced? Weight Capacity How much weight can the spike cover hold? Fit Does the spike cover fall off? Do the spikes fit within the holes? Do the covers fit the portion of the shoe? Does the spike cover protect the spikes? Do spikes become damaged when wearing the spike cover? Does it eliminate the need to change shoes? Is it faster to use the spike cover than to bring an extra pair of shoes? Physical Appeal Does it look good?

Testing Aspects Safety: Wear spike covers. Walk on different surfaces. If the cleats slip, it fails the safety test. If the spikes do not slip, it passes the safety test. Weight Capacity Wear spike covers Add weights to the person to test the durability of the spike covers Record weight. Goal Capacity: 200 lbs. Fit Place spike covers on sole Does the covers fall off or become loose while walking? Examine if the spikes fit into the given holes Finally, examine if the spike covers fit the sole of the cleats correctly. (not too big and not too small) Does the spike cover protect the spikes? Wear the spike cover and walk Do the spikes of the cleats become damaged in any way? If they do, test is failed. If they do not become damaged, the test is passed. Does it eliminate the need to bring two different pairs of shoes? Is it faster to use spike covers than to change from shoe to shoe: Time someone using the spike cover. Time starts when he/she begins to put on the spike cover. Time finishes when he/she takes of the spike cover. Then, have the same person start a new time trial with spikes already on. Start the time when he/she starts to remove the shoe. Stop the time when the other shoe is completely on. Compare the times. If the spike cover time was faster than the shoe-to-shoe time, the test is passed. Physical Appeal Test by giving the appearance of the product a score on a scale of 1-10. (7 and above is a pass)
