Team Charter
Before jumping into our design project, our team established a team charter which acted as an agreement between us of our commitment to the project. Our team charter identified our personnel & stakeholders, roles & responsibilities, mission & vision objectives , along with our internal checks throughout the project. Our team remained committed to this charter and we shared many of the responsibilities to make the best project we could.
Project Schedule
In order to keep our commitment to the project on a manageable and appropriate timetable, we developed a project schedule which outlines our team meetings, our task progressions, as well as all of the deadlines we needed to meet. We generally remained committed to this schedule but made adjustments as needed.

Concept Generation
To begin the process of concept generation for our design, each of us studied our patient's case and independently designed a set of two unique preliminary sketches of a proposed design that we see feasible. The photo to the left is my own first preliminary sketch.

Preliminary Materials Selection
As a team, we performed a materials selection to identify a preliminary list of materials suitable for our specific design. We performed this for each component of our implant depending on which material is justifiably suitable for certain parts. We completed this materials selection using the materials triangle worksheets from the design studio handbook. This materials triangle served as a tool to justify our materials choices based on several factors regarding them.

Preliminary Design Analysis
As a team, we were required to analyze the appropriateness of specific design parameters for our team's custom hip implant, namely the material and diameter of the implant stem. Provided some key information, we performed an exercise where we were required to calculate the fracture risk of the implant stem, calculate the fatigue life of our assigned material, and calculate the reduction magnitude of bone stresses after implant reconstruction.
