## 7 Feasibility, Scalability, and Performance Evaluation
### The mPOC Technical Feasibility Study  
The mPOC technical feasibility study evaluates various factors to determine if the system is feasible from technical, economical, operational, social, legal, ethnical, scalability, sustainability, and risk perspectives. In this article, we will only cover the technical feasibility aspect of the mPOC system. The feasibility of other factors can be considered in future studies.  
The technical feasibility of the mPOC system focuses on evaluating the practicality and viability of its technology components. This assessment considers various technicalaspects to determine if the system can be successfully developed, deployed, and operated. Here are the key factors involved in the technical feasibility of the mPOC system:  
System Availability: This includes assessing the availability of hardware components, such as smartphones and wearable devices (e.g., Bio-Watch). It also considers the availability of software components, including the mPOC application and algorithms necessary for data processing and analysis.  
Sensor Integration: The mPOC system relies on the integration of sensors to capture clinical and physiological data. This assesses the availability and functionality of sensors that can accurately and reliably measure vital signs, symptoms, and other relevant health data. This includes evaluating the compatibility of sensors with the smartphone and wearable device, ensuring seamless data collection and transmission.  
Connectivity: The mPOC system requires connectivity options to transmit data between the smartphone, wearable device, and other public domain stakeholders, such as the OTC. This feasibility study examines the availability of wireless communication technologies, such as Bluetooth, Wi-Fi, or cellular networks (4G/5G), to establish reliable and secure connections. It ensures that the chosen connectivity options are capable of handling the required timely (real-time) information exchange.  
Data Processing and Analysis: This required the computational evaluation of the capabilities of the smartphone to handle the processing and analysis of data collected by the mPOC system. This includes assessing the processing power, memory, and storage capacity of the smartphone to perform complex algorithms and classification tasks. Additionally, it considers the availability of fog/edge computing techniques to offload some computational tasks and improve efficiency.  
Data Security and Privacy: This technical feasibility encompasses the assurance of robust (personal/public) data security and privacy measures within the mPOC system. This involves assessing encryption mechanisms, secure data transmission protocols, and access to control measures to protect sensitive health information. The system may require compliance with relevant data protection regulations and standards (e.g., NIST).  
System Scalability: This examines the scalability of the mPOC system to accommodate a potentially large number of users. It assesses whether the system can handle increased data volume, simultaneous connections, and user interactions without compromising performance or data accuracy. Scalability considerations may involve evaluating the network infrastructure, server capabilities, and data storage capacity.  
Integration with Existing Infrastructure: In many cases, the mPOC system needs to integrate with existing healthcare infrastructure and information systems. This feasibility study evaluates the compatibility and interoperability of the mPOC system with Electronic Health Record (EHR) systems, laboratory information systems, or public health databases. It ensures seamless integration and data exchange between the mPOC system and other healthcare systems.  
By conducting a thorough Technical Feasibility assessment, the end-users can determine if the mPOC system's technology components are readily available, compatible, and capable of meeting the system's requirements. This evaluation provides valuable insights into its development.
