5. Verification and Validation
6. Clinical Evaluation
7. Usability engineering
8. Cyber security

The FDA guidance outlines several key elements that need to be addressed in premarket submissions for device software functions. This section will delve into each element in detail:

1. Device Description: Manufacturers must provide a comprehensive description of the device, including hardware, software, and any associated accessories. It is important to tailor the device description to meet the specific requirements of the medical device and clearly state the purpose of the software and describe its intended use in the context of the medical device. Explain how the software contributes to the overall functionality of the device and its intended medical application. Example: Is it a software-only device, software that controls the device hardware, software application that accompanies the device for data processing?
2. Risk Analysis/assessment/PSRT: A thorough risk analysis should be conducted to identify potential hazards, assess risks, and outline risk mitigation strategies. According to the new guidance Manufacturer should conduct a comprehensive risk assessment targeting Individual risk acceptability criteria including the need for risk reduction, to identify and evaluate potential hazards associated with the software. This involves identifying potential risks, estimating their severity, and determining the likelihood of their occurrence. In Risk assessment, both inherent risks associated with the software itself and those arising from its interactions with the medical device should be considered. They have to develop method to evaluate the acceptability of the overall residual risk, for all residual risks after all risk control measures have been implemented and verified.
3. Hazard Analysis: Hazard analysis in software for medical devices is one of the critical components of the overall risk management process. This section will cover the importance of identifying and evaluating potential hazards associated with the software's intended use and evaluating their severity, probability of occurrence, and the level of risk they pose to patients, users, and others associated user or device; and explaining how these risks are mitigated.
4. Software Development Process: The software development process involves a series of activities and stages aimed at creating high-quality software. While there are various methodologies and approaches to achieve the goal, FDA expects manufacturers to follow a robust software development lifecycle, including documentation of planning, Software requirements, Software architecture, software design, development, testing, deployment, operations, maintenance, verification, and validation activities, to ensure a safe and effective software.
5. Verification and Validation: Verification and validation are essential in software development to ensure that the software meets requirements, functions correctly, delivers high quality, mitigates risks, satisfies users, complies with regulations, saves time and cost, and builds trust and confidence among stakeholders. Therefore, Manufacturers must provide evidence that the software has been tested and validated to ensure its safety, effectiveness, and reliability.
6. Clinical Evaluation: This element discusses the importance of conducting clinical evaluations to validate the performance and safety of the device software. It involves the systematic and ongoing assessment of clinical data and relevant scientific literature to establish the safety and performance of a medical device software while assessing the device's intended use, indications, benefits, risks, and any adverse effects associated with its use.
7. Usability Engineering: Manufacturers need to demonstrate that the device software has been designed with human factors principles to ensure ease of use and minimize the risk of user error. Usability engineering follows a user-centred design approach, where the needs, characteristics, and abilities of the intended users are central to the software development process. User research and usability testing are conducted to understand user requirements, workflows, and preferences of targeted users.
8. Cybersecurity: Inadequate encryption and data protection mechanisms can expose sensitive data during transmission, storage, or processing. Without proper encryption, data can be intercepted or compromised, leading to privacy breaches or unauthorized access. Given the increasing concern of cybersecurity threats, manufacturers must address cybersecurity risks associated with the device software and outline mitigation strategies.
