iOS splash screen
OnForce

We began our process with a lengthy internal brainstorming session that yielded hundreds of ideas and directions, which were scoped down to a minimum marketable product. Moving quickly into wireframing followed by hi-fidelity prototyping, we hosted a dozen informal usability sessions with our service technician users over the course of several weeks, using RealizrApp, before beginning development

For the sake of speed, we elected to use Appcelerator's Titanium development platform, which allows for simultaneous iOS and Android development using compiled JavaScript instead of native Objective C or Java. As development progressed, we entered a closed beta which yielded immensely important user feedback which we incorporated into the app. We initially released to the iTunes store in December 2011, where we currently have a 4.5/5 rating.

As the sole designer, I led the team's efforts in interaction and visual design, creating screen mockups, wireframes, and workflows, as well as ensuring that the look, feel, and interaction methods of the app were in line with iOS standards. During the course of development, I worked closely with our technology team to implement the design work, re-working screens and design elements as needed to collaboratively solve technical challenges.

The summary view of an in-progress, or "accepted," OnForce work order in the iPhone app. This view provides an OnForce field technician with the critical information they need to perform the work, while providing acces to several key actions.
The summary view of an incoming, or "new," OnForce work order. This view provides different information and actions, being optimized for quick review of the information that will help the technician decide if they wish to accept the work. The tab view indicates that the user is viewing a "new" work order.
A dialog for checking in to a work site for accepted work orders. "Chaining" logical actions together, like a call to the service contact during the check-in process, is one of the ways that we optimized the app for true efficiency in the field.
The general list view of accepted work orders. The filter button allows for the user to view only work orders on the docket for the current date, or all currently open work orders they have accepted.
