Medical Device Development Process

Medical devices of increasing complexity are central to mankind's continuously expanding ability to save lives and improve the quality of life. Within our business, we often reflect on how fortunate we are to have the opportunity to work on a variety of these remarkable devices. We believe that such rewarding experiences are made possible through the application of a rigorous system engineering process, ensuring that the resulting devices are safe, effective, and successful.

This article describes a deployed System Engineering process tailored for Medical Device Development within Battelle Medical Device Solutions (MDS). This process (based on ISO 15288:2002, the INCOSE System Engineering Handbook and a Legacy Process), integrates compliance to international regulations, embeds a Safety Risk Management process as defined in ISO 14971:2007, and assures adherence to ISO 13485:2003 Quality Management Systems. Based on the classification and complexity of the device, the process is scalable, may be tailored, and is iterative.


Medical devices range from very low risk devices (tongue depressor) to moderate risk devices (drug delivery infusion pump) to high risk devices (implanted pacemaker). In a similar fashion, the complexity in terms of functionality of medical devices range from low complexity (tongue depressor) to moderate complexity (hand-held blood glucose meter) to high complexity (an in-vitro diagnostic clinical laboratory instrument). The development of medical devices requires a wide diversity of stakeholders and disciplines as indicated in Table 1, Medical Device Development Stakeholders.

Table 1 - Medical Device Development Stakeholders

Medical Device Stakeholders

The consequences of not being inclusive of all of the stakeholders vary from developing a medical device that no one wants to purchase, to placing a device in the market that can harm a patient. The development and manufacture of medical devices under a controlled environment is essential to assure that the device will be safe and effective in accordance with its intended use.

This article presents the results of the development and deployment of a medical device development process which meets this diverse set of conditions.


A systems engineering process was used to develop the Medical Device Development Process (MDDP). The process started with elicitation of the process stakeholder needs and wants, translating the needs and wants into verifiable requirements, developing the process, verifying its implementation (did we implement what we designed) and validating (did we implement the right process). The MDDP has been in full deployment since July 2008.

The most significant stakeholder need was to have an integrated process, i.e. one process that is inclusive of the Quality Management System requirements, business policies/practices and the product development process. Previously project teams would need to understand three separate processes that were loosely coupled. The MDDP merged all three into a single process that is tightly coupled.

Figure 1, Consideration Elements for the MDDP, graphically indicates the elements that influenced the development of the MDDP.

MDDP Elements

Figure 1 - Consideration Elements for the MDDP

The Medical Device Development Process

The process needed to:

  • Be a repeatable process that can be applied consistently across varying scopes of projects and devices
  • Be inclusive of the entire life-cycle of a medical device
  • Provide clear and concise direction; only tailoring allowed will be based on the scope of the project
  • Allow for Project Manager/Customer flexibility versus a rigid process
  • Be a vehicle for conveyance and reinforcement of lessons learned
  • Identify well-defined milestones throughout the process
  • Be a functional tool for Marketing such that they can convey the process to customers
  • Provide a tiered and structured approach such that different views are readily accessible, e.g. Marketing, Senior Management, Customers, Project Teams
  • Provide documented direction for project teams in the form of templates, checklists, training materials, etc.
  • Be harmonized with the MDS Quality System
  • Be compliant with applicable regulations and standards
  • Incorporate a common glossary of terms, abbreviations and acronyms
  • Support an iterative process for design and development
  • Recognize all stakeholders and integrate at appropriate points in the process
  • Identify activities, tasks, and deliverables for each phase and the stages within a phase, clearly articulating gates with entry and exit criteria
  • Clearly delineate where in the process Design Reviews need to occur
  • Deploy a unified change control process with clearly articulated roles and responsibilities
  • Recognize the need for defect tracking and integrate into the process
  • Define a tool validation (medical device regulatory requirement) process that can be uniformly applied across projects

The design output of the MDDP resulted in an integrated process that merged the Quality Management System with the product development process. Figure 2, MDDP Design Output, illustrates the integrated process.

The MDDP has six defined phases. These phases and their transitions are shown in Figure 3, MDDP Life Cycle Phases. At the end of each Phase is a review. It is possible that all activities will not be complete at the time of this Review. The MDDP enables the project to move into the next phase based on a conditional acceptance recognizing that not all elements may be completed. Both the customer and the MDS management team need to accept the risks and align to move forward. This process will ensure that all major stakeholders are cognizant of where the project stands and are in alignment that the project should move forward or should stop until certain elements have come to closure.

MDDP Design Output

Figure 2 - MDDP Design Output

MDDP Level Cycle Phases

Figure 3 - MDDP Level Cycle Phases

Feasibility Phase: where the suitability of technology for a clinical need is identified and evaluated, device concepts are generated, and technical risks begin to be identified and reduced.

Design and Development Phase: where the device requirements are established and translated into a verified and validated device design.

Design Transfer Phase: where the device design is translated into production specifications.

Production Phase: where the decision has been made to proceed forward to manufacture the device for commercialization and sale, including steps to plan, promote, market, sell and also for the servicing and support of the device.

Sustaining Engineering Phase: where the marketed device is supported in its operational environment.

Device Retirement Phase: where the device is removed, dismantled, destroyed or recycled as per the manufacturer's device retirement plan.

Context diagrams were created for each phase as defined in the life cycle model, for each stage within a phase and each activity within a stage. Figure 4, Design and Development Context Diagram, illustrates a phase context diagram.

Design and Development Context Diagram

Figure 4 - Design and Development Context Diagram


The MDDP has been in full deployment since July 2008. Efficiencies are being seen in that the staff and product development teams only have one process to understand and deploy. This has reduced training burden, alleviated staff frustrations, and reduced maintenance (less processes/systems). That does not mean that the work ends here. It is critical to continually review the process and update it based on the user's experiences, updated requirements coming from regulatory and the standards we adhere to, and the latest advancements and best practices in the various tasks and activities. A team must be dedicated to ensure the process is state of the art to guide medical device development in the best, most efficient manner and most importantly create medical devices that are both safe and effective. The failure to do so can be measured both in terms of human life and financial losses to individuals and companies.

As medical devices become more integrated with other systems, combined with drugs and/or biologics, are intended for use in the home rather than in a clinic or hospital, and enter new frontiers in technology such as micro and nanotechnology, the significance of the MDDP as the backbone to medical device development becomes more apparent. A medical device designed to an intelligent, thoughtful process will yield a device that has a higher likelihood of getting to the market and making a tangible, positive difference in society.

SysML Request for Information (RFI) Issued as On-Line Survey to Support SysML Roadmap Development

June 29, 2009 - A SysML Request for Information (RFI) was issued at the June '09 OMG meeting. Response to the RFI is requested via the SysML RFI on-line survey. This information will be used as an input to develop the SysML Roadmap in support of Model-based Systems Engineering (MBSE). In addition, the response can help you assess how SysML and MBSE are being practiced within your organization. The RFI is intended to be distributed to SysML users, tool vendors, and academia to help identify how SysML is used, issues, proposed resolutions, and new features to support the roadmap. The roadmap could include a combination of incremental updates through the SysML Revision Task Force as well as a new Request For Proposal (RFP) for a significant revision to SysML. The RFI includes a survey with specific questions relative to SysML, and more general questions related to the application of SysML to model-based systems engineering (MBSE). Response are due by November 9, 2009, with the results and selected responses to be presented at the OMG SE DSIG meeting the week of December 7-11, 2009. Dr Rob Cloutier from Stevens Institute (USA) prepared the on-line survey format and will be compiling the survey results, to be made available to OMG, INCOSE, and other members of the systems engineering community.

Unleashing the Next Wave of Engineering Innovation

By Cameron Burns, June 11, 2009,

..."Engineering schools don't specifically teach bad engineering design," notes RMI's Alok Pradhan, "It's just that current engineering practice is very siloed and there's a lack of integration and whole-system consideration. Designs are typically optimized for the wrong parameters. That is, they will optimize the component individually, and the pieces -- when they fit together - don't work that great as a system."...

...Pradhan is the project manager for 10xE, which is short for Factor Ten Engineering. Several years ago, RMI kicked off this modest project to address these problems in engineering. This RMI initiative is fairly straightforward: The goal is to create a series of teaching tools that will help engineers design the things they design using radically less energy and resources than they otherwise would have, without compromising performance. These teaching materials - revolving around a casebook of extremely efficient projects and systems -- will be used to teach efficiency concepts and design to both engineering students and practitioners...

Systems Thinking Blog Series

This series of blogs focus on basic systems thinking as it is applies to our energy structure. It will also integrate some of the learning that lean practices provide, as well as the scientific principles of The Natural Step. The learning will only touch the surface with the hope that you will take the learning and/or ideas further and, as importantly, applying the learning in the job you are in now. The intent is to focus on leverage points of complex systems, so we can move our complex energy system more toward results we desire. Unfortunately, the behavior of complex systems involves collapses and oscillations, not linear behavior lines. A challenge for us is that to change complex system behavior is often counter-intuitive. Also, complex systems will surprise us because we can't understand and anticipate all interactions within a series of complex subsystems comprising an overall system.

How Do We Become a Systems Thinking Organization?

Monday, June 22, 2009 by Tripp Babbitt

"A natural question for the curious is "how to do something." What are the steps to becoming a systems thinking organization? The answer I will leave you in this blog will be somewhat of a paradox consistent with the discipline itself. First of all, you can't copy another organization, each organization is unique and part of systems thinking is understanding that copying can lead to more problems. And it was Dr. W. Edwards Deming that said that it is difficult for an organization to see itself. So combining theory and knowledge the Vanguard Method takes organizations through a learning model that requires an unlearning and relearning method to change thinking. We believe that this is best done with the work so one can see the waste and inefficiency in your organization."

Early Verification and Validation Using Model-based Design

By Brett Murphy and Amory Wakefield, The MathWorks -- EDN, 7/9/2009

...The rapid growth in processor speed and memory that enabled the development of modeling, simulation, and code-generation tools on the desktop also enabled embedded-software developers to increase the functions and complexity of embedded controllers. This step in turn drove the need to move beyond traditional code-development techniques using text editors and debuggers to center design on models. This model-centric development approach is known as model-based design…. ... The primary way model-based design achieves verification and validation is through testing in simulation. Although many organizations do some form of modeling, too many apply simulation in an ad-hoc manner that does not maximize the potential verification benefits. Simulation alone cannot find all errors; however, it is a huge step forward, and you can do it almost as soon as you design a model. Iterating in a modeling environment is fast and easy...

...In software there were few physical rules to be automated. For those writing device drivers the design of the hardware gave good guidance. Likewise for those writing control programs for microprocessors. But when it came to 'applications' the rules were much less clear...

...We became convinced that success in computer-aids for software engineering would not lie in physics-based models but in models of how designers think (or not) and how to facilitate higher order thinking (Janusian, Hegelian, etc.)...

...Models are essential. I think we all have demonstrated that specifications or other written descriptions ABOUT things, the interaction among things and the interactions among the interactions simply do not communicate...

...For second order or higher implicit systems a key factor is that any modeling language and tool must allow a model of the system to be one of the 'things' in the system and allow the model to affect the system's gradients, pattern of relationships and even content of 'things.' I have yet to see how SysML allows that...

Standards and Guides

Recommended Practice for Architectural Description of Software-Intensive Systems ANSI/IEEE Std 1471 : ISO/IEC 42010

In July 2007, ISO published ISO/IEC 42010:2007, Systems and software engineering - Recommended practice for architectural description of software-intensive systems. The text of this ISO standard is identical to IEEE 1471:2000, and was intended to serve as basis for a joint ISO and IEEE revision.

That revision has been proceeding, and is of Working Draft 4 (WD4) status. The revision includes an expansion of scope to directly align to ISO/IEC 15288 (systems) as well as ISO/IEC 12207 (software).

Some Definitions to Close On - Performance, Performance Requirement


The degree to which a system or component accomplishes its designated functions within given constraints, such as speed, accuracy, or memory usage
(ISO/IEC 24765:2008, Systems and software engineering vocabulary)

Note from Robert Halligan: despite the ISO/IEC 24765:2008 definition, memory usage is not a measure of performance, since it is not a measure of the degree to which the system accomplishes/is to accomplish a designated function.

Performance Requirement

  1. the measurable criterion that identifies a quality attribute of a function or how well a functional requirement must be accomplished
    (IEEE 1220-2005, IEEE Standard for the Application and Management of the Systems Engineering Process , 3.1.26)
  2. a system or software requirement specifying a performance characteristic that a system/software system or system/software component must possess (ISO/IEC 24765:2008, Systems and software engineering vocabulary)
  3. a requirement that imposes conditions on a functional requirement (ISO/IEC 24765:2008, Systems and software engineering vocabulary)
