Team Vision for Problem Definition Phase

The main goal of Phase 1 was to fully comprehend the scope of our project. In order to do so, minor set points had to be reached like interfacing with our customer, establishing team roles, planning a strict schedule to follow, and other similar tasks.

Required Tasks:

Other Accomplishments:

Stakeholders

Stakeholder Primary Contact Communication
Customer Dr. Rui Liu rleme@rit.edu
RIT Machine Shop Jan Manetti jameme@rit.edu
Grad Students TBD
Future MSD Teams TBD

Customer Requirements (Needs)

Purpose: The customer requirements help visually portray the various aspects of the problem statement that must be considered when entering the design phase. They also help ensure the scope of the project is kept within a practical range. Using feedback from meetings with our customer, we compiled this table of customer requirements.

Key Takeaways

Engineering Requirements (Metrics & Specifications)

Purpose: The engineering requirements visually detail the specifications that the project will need to conform to. They also help quantify the customer requirements.

House of Quality

Purpose: The house of quality allows the design team to determine if their customer requirements are being fulfilled by the engineering requirements and if their engineering requirements are actually contributing towards a customer requirement.

Design Review Feedback

This section documents the feedback and resulting action items from our first Design Review.

Dr. Liu

Feedback Action Items
Ensure all risks are documented in the preliminary and design risk assessments. Update preliminary risk assessment and pay special attention to design risk assessment.
Stiffness of device needs to be considered. Documented as an Engineering Requirement and will be fully quantified later in the class.
Durability of circuitry must be addressed. Added using PCBs as a constraint.

Gary

Feedback Action Items
Ensure that how the weight of the device affects the machining process is considered. Added as a constraint.
Sampling rate needs to be addressed. Added as an Engineering Requirement which will be quantified later in the class.
Put more thought into how the repeatability numbers are chosen. Left blank until a detailed study can be made.
Risk assessment items need owners. Individual team members assigned to risk items.
Rework WBS and Gantt chart. Attended an info-session on project-planning and updated WBS and Gantt chart.
