Medical technologists are developing a new type of pacemaker that, when planted inside a human’s chest, uses electrical impulses to help keep a steady heartbeat. The new design will send warning signals to a patient’s hospital sooner when it detects an upcoming heart problem. In testing so far, this new feature has only worked in about 25% of test patients. How does this product most likely need to be improved before doctors can report that the new technological design is successful? The product needs to better solve the problem for which it was designed. The product needs to become available to the public more quickly. The product needs to become more time effective when it is being built. The product needs to make better use of available building materials.
