iOS App for Field Service Engineers


GE Energy management customers were unable to quickly access machine parts information and identify spare parts resulting in 6+ months cycle times, dissatisfied customers and lost opportunities.


To create a mobile app that will enable field engineers, sales engineer and external customers to identify the part by capturing images using smart phone camera. Captured images will be matched to the database of parts and the customer will be presented with parts information & availability and ability to submit their order.

My Role

Project Leadership, Competitive Analysis, Wireframing and Prototyping in Axure, Usability testing along with Researcher, Presenting the finding and recommendations to stakeholders.


Our approach was to first conduct workshop with the stakeholders to understand the business needs and identify who our target users were. From our sessions, we got insights into the business flow of parts ordering and understood the priorities.


Our next step was to conduct 1:1 interviews with target users to gain understanding of their needs and painpoints. We used that information to create the personas below.

Task Flow

We identified the key capabilities that the user would need such as Dashboard, Search, Camera, ability to mark as favorites, add to a list and submit for request. We created a high level task flow and this informed the information architecture and screens required.


Initial sketches helped explore how the information on the screen could be presented and what functionalities should be emphasized.

Usability testing

We conducted usability testing with a mix of sales engineers, parts engineers and field engineers. Here is an outline of the test objectives.
