Some of the most common challenges that STEM students face when working on their capstone projects include difficulty defining the scope of the project, lack of domain expertise, insufficient research and planning, ineffective time management and organization skills, issues with team dynamics and collaboration, incomplete understanding of the engineering design process, lack of adequate resources and funding, regulatory and compliance difficulties, difficulties with manufacturing and prototyping, and stresses related to the open-ended nature of capstone projects. Let’s explore some of these challenges in more depth:

Defining the project scope is often one of the biggest hurdles that capstone teams struggle with initially. Coming up with an innovative yet feasible idea that can be completed within the constraints of a semester-long course is no easy task. Students have to pin down the objectives of the project and determine what can realistically be achieved given their skills and the timeline. This involves considering technical, budgetary and other limitations. Figuring out the scope early on sets the stage for successful planning and execution, so difficulties here can cause major issues down the road.

Another major challenge is the lack of domain expertise. Capstone projects are intended to push the boundaries of students’ knowledge and abilities. Delving into an unfamiliar application area without sufficient background knowledge makes the tasks of problem formulation, research, design and prototyping that much harder. Students may struggle to differentiate between relevant and irrelevant information, ask informed questions to experts, and generally navigate uncharted disciplinary territory. Acquiring the necessary expertise on short notice requires strong self-learning skills and a willingness to admit knowledge gaps.

Even with a well-defined scope, research and planning challenges can derail capstone efforts. Students have to survey the existing literature, technologies and approaches to solve similar problems. This research forms the foundation for evaluating alternatives and selecting the most viable design solutions. Many students don’t allocate enough time for planning or conduct research in a superficial way. Insufficient evidence gathering and analysis during project planning leads to rushed, incomplete or infeasible designs further down the line.

While time management is a problem for many academic projects, capstone projects magnify poor organization skills. With no strict milestones or deliverables beyond the final presentation date, it’s easy for tasks to slip through the cracks without accountability. Leaders must effectively delegate responsibilities and track progress, while all team members commit to individual workloads. Unexpected setbacks or distractions can jeopardize deadlines if slack isn’t built into schedules. Capstone work also intensifies towards the end, so inefficient time usage early on compounds stress later on.

Team dynamics present unique people challenges due to the high-stakes nature of capstone work. Personalities, work ethic and communication styles vary widely across groups. Division of labor issues, social loafing behaviors, conflicts over design decisions and lack of cohesion/trust undermine productivity and morale. Leadership struggles, free-riding problems and interpersonal tensions are also amplified without a supervisor. Developing collaboration skills to get through inevitable conflicts constructively takes effort for most students.

The open-ended engineering design process itself can mystify inexperienced student designers. While the general iterative approach of defining problems, researching alternatives, selecting solutions, building prototypes, testing and refining is understood, the subtleties of each stage are harder to master without real-world project experience. Establishing clear specifications, evaluating design trade-offs quantitatively, and executing multiple design-build-test cycles demanding. Milestones like preliminary and critical design reviews also require a professional quality of work not common for undergrads.

Acquiring necessary resources and funding is challenging particularly for physical hardware projects like robots and biomedical devices. Sourcing specialized components, materials, equipment for fabrication, testing and certification stretches limited departmental budgets and requires grant-writing skills. Adhering to regulatory standards like safety protocols for testing on humans or animals requires extra expertise. Manufacturability and producibility are also difficult subjects for students without industrial contacts.

While capstone projects aim to provide an authentic engineering experience, the range of challenges that arise are substantial for most undergraduates to navigate independently. Achieving success requires overcoming difficulties in problem definition, research planning, time management, team collaboration, following an unfamiliar design process, securing resources, and gaining domain expertise – all within a single academic term. Support from faculty advisors helps guide students through these challenges to produce impactful work.
