Study Notes

Biomedical Devices Overview

Modified devices can include personalized braces, tracking devices for patients and pets, hand exercisers, and adjustable trays for spinal cord-injured individuals.
Innovations like improved safety systems in ICUs and patient monitoring for premature infants are vital.

Medical Device Development Challenges

Less than one-third of medical device projects reach the marketing stage.
Engineering methods can significantly lower failure risks in medical design.

Design Process and Methodologies

Product Development Life Cycle follows a sequential waterfall model: from planning and requirements analysis to design and implementation.
Testing involves validating requirements and confirming functions, often requiring clinical trials for certification.
System decomposition is essential for managing complexity, allowing parallel activities among project teams.

System-Subsystem Decomposition

Dividing systems into subsystems helps in managing complexity and lowers risks, costs, and development time.
The decomposition involves defining actors, interfaces, and systems at various levels, iteratively increasing detail until clarity is achieved.

Business Context and Design Failures

Reasons for product design failures include misalignment with market needs and delays in development that miss critical opportunities.

Project Management in Product Design

In risk management, continuous monitoring of identified risks is crucial, along with assessing their probability and economic impact.
Budgeting for risk management should account for potential additional costs due to identified risks.

Performance and Team Dynamics

There is typically a time lag needed for teams to accumulate necessary knowledge and skills, which diminishes as experience with tasks increases.
