Most of us have experienced a critical path situation during the senior design capstone project. We were designing a product that monitors blood glucose, heart rate and activity that securely transfers data to a remote server. All the data is posted on an UI, which is accessible to family members and doctors. We talked to few professors within the CS department at NJIT and it was thought that getting access to NJIT free server was an easy task. However, as the project continued, we realized that server used an HTTPS (secure protocol). On the other hand, our hardware (Arduino) was only compatible with HTTP protocol. The devil’s in the details was important and something so simple became our critical path for the project. We did not check the compatibility of two pieces of equipment and as a result ended up reevaluating our options of hardware.
