Healthcare

Oregon Health Sciences University - Trigeminal Neuralgia Diagnostic Tool Design and Code

Overview: The Oregon Health Sciences University Department of Neurological Surgery required a web interface to leverage a custom built Artificial Neural Network contained in a NeuroDimension construct.

Solution: Webfoot teamed with OHSU Doctors and IT specialists to determine a technology best path for this web application. Since OHSU had already built the Artificial Neural Network using NeuroDimension software it was decided that a custom VB COM+ component be built to handle transactions between the Neural Network, business logic, data and presentation layers. The final application consisted of two dll's (a NeuroDimension Neural Network developed by OHSU and a Webfoot dll). Application meta data was stored in a SQL Server database which also contained stored procedures which were called by the Webfoot dll. The entire application architecture was designed with HIPAA in mind including database schema and the use of SSL.

The application accepted input from users in questionnaire format which was submitted to the Neural Network after which a results page containing a probable diagnoses was presented.

The Administrative interface for this application allowed for adding, updating and deleting users in addition to reviewing diagnostic results.

Technology

Hewlett Packard - Management Status Update Application Design and Code

Overview: HP required it's managers to provide weekly project status report using email. Once a status email reached a top level manager it was difficult to read since there were so many sub-manager status roll-ups. In addition, many roll-ups were incomplete since members of a reporting chain would forget to contribute to an email thread or fail to forward emails up the management chain.

Solution: Webfoot suggested an application be built which would alert all responsible parties via email when a status update was required. Further, each project would maintain an update history which could be accessed by way of a simple query builder tool. Edit permissions would be provided to each manager up the project chain to all the managers under the chain which provided project governance in keeping with the HP management model. A color scheme was applied to represent projects in various status states (red/yellow/green) which was helpful to top level managers who had many status reports to review each week and could determine trouble spots at a glance.

This application is now the property of HP and operates behind a firewall which precludes Webfoot from offering the general public any links or images which may otherwise be useful to this case study.

Real Estate

John L. Scott - Quality Assurance

Overview: Webfoot was approached by Real Tech LLC to provide Quality Assurance on all of their flagship Real Estate web applications. In addition to a high level of quality required for the final product it was also important that the entire QA cycle be completed in time for a pre-packaged and paid for TV and radio advertisement campaign.

Solution: Webfoot uses a Test Plan document loosely based on IIE-829 specifications but modified for the quickly changing requirements and development practices associated with web application development. Of great benefit for testing web applications is the use of a detailed functional requirements area within the Test Plan which is then mapped to specific tests in a Test Specification document. This method allows for budget and deadline scaling on the fly in order to meet customer requirements and expectations.

Our approach was very successful for the John L. Scott QA campaign as we completed our testing on time and under budget. We were so successful in fact that Real Tech continued to use our proprietary QA resources for all of their high value projects.
