Design reviews are typically used for three types of design activities: 1) identifying errors, 2) assessing the impact of the errors, and 3) suggesting solutions for the errors. This experimental study focuses on understanding the second issue as it relates to the number of errors considered, the existence of controls, and the level of domain familiarity of the assessor. A set of design failures and associated controls developed for a completed industry sponsored project is used as the experimental design problem. Non-domain individuals (psychology students), domain generalists (first year engineering students), and domain-specialists (graduate mechanical engineering students) are provided a set of failure modes and asked to estimate the likelihood that the system would still successfully achieve the stated objectives. Primary results from the study include the following: the confidence level for all domain population decreased significantly as the number of design errors increased (largest p-value=0.0793) and this decrease in confidence is more significant as the design errors increase. The impact on confidence is less when solutions (controls) are provided to prevent the errors (largest p-value=0.0334), the confidence decreased faster for domain general engineers as compared to domain specialists (p=<0.0001). The domain specialists showed higher confidence in making decisions than domain generals and non-domain generalists as the design errors increase.

[edit] Engineering Experience

Graduate Research Assistant, Clemson University
Testing and Performance Analysis of Tent Ballast-IFAI, 2011
In this project, test equipment and a testing protocol were developed to collect data on the movement resistance (friction) of different ballast types (concrete barrels, water barrels, cement blocks), different surface conditions (dry pavement, wet-smooth concrete, grass, gravel), with different modifying interfaces (neoprene, plywood, steel plates). These resistance coefficients are used in an industry tool to help large tent manufacturers, installers, and renters to determine the appropriate configuration of ballast needed.

Industry sponsored project, Bosch Rexroth, Bangalore INDIA
Project title: Electronically Controlled Infinitely Variable Pressure Control for CNC Lathe, 2010
This project, supported by Bosch Rexroth, dealt with the design and fabrication of a hydraulic power pack. The system can be connected to the headstock or tailstock of a CNC Lathe and the pressure can be varied electrically to achieve the required clamping force of a hydraulic chuck. The variation of clamping force for shafts of different materials can be achieved through this.
