Modeling to Learn

About The Client

WaferWire developed a project for one of its renowned client that was dealing in Veteran’s affairs. The client was working closely with a Posttraumatic Stress Disorder (PTSD) Center. The client was keen on offering effective treatment to its patients and improving patient care and social welfare through research, education and training in the diagnosis and treatment of stress-related disorders including PTSD.

The Client Requirement

The client intended to

  • Build ‘Modeling to Learn’, a Participatory System Dynamics Platform to Increase Timely Access to Evidence-based Outpatient Mental Health Care.
  • Program a user-centered interface by working with Veteran patients, providers and policymakers. This interface was aimed to display real de-identified aggregate data and can model what-if scenarios to determine likely trade-offs from common clinic redesign decisions.

For developing the solution, the client planned to use Forio – web-based simulation platform.


The WaferWire team built the entire solution from scratch on top of the ‘Forio – web-based simulation’ platform using the Iterative Delivery Model. The solution is 508 compliant as mandated by the federal law which states that all electronic and information technology developed, procured, maintained or used by the federal government should be accessible to people with disabilities. The solution was developed and deployed in a timeline of 1 year and 6 months and is primarily used for taking inputs from Veteran patients for Vensim System Dynamics Model using custom made web-based simulations.

Following design web interfaces of Vensim System Dynamics Model were customized for the client –

Making a clickable and responsive design of Model was a challenging task in HTML5 which can support from 320 to 3200-pixel resolution. WaferWire team had not worked with Forio before this project. Also, certain requirements needed solutions that posed challenges due to the limitations in the Forio platform. However, the team not only studied the new technology within 2 weeks but also overcame the software limitations by offering an out-of-the-box approach to build the non-supported features. To mention a few, the team used Forio data API services to store objects with custom coding to manipulate them as Forio doesn’t support the Relational Database Management System. Forio uses ‘gravatar’ third party services for user profile picture which were restricted in the client’s environment due to the strict internet policy. To overcome this challenge, the team used Forio file upload API with custom code.

With the technical niche and innovative solution strategy, the team could deliver the project within schedule and received accolades from the client.


  • Business Value & Customer Satisfaction – The required functionality was delivered within time with outside the box thinking and Iterative Delivery Method.
