Customized Mobile Application Development


Mobilizing a Field Work Force

What the client wanted:

An environment management services company wanted to streamline the daily routine of their field technicians and make communication between the field and the central office easier and more efficient. They desired a tool that would provide real-time access to the technicians while working at a clients site, eliminate the need for multiple daily visits to the office, and allow them to access directions and street-level maps with the push of a button.

What SD3 did:

SD3 created a customized mobile application that ran on each field technician’s mobile phone and communicated real-time job data to the central office. After finalizing the requirements and workflow for the app, SD3 defined the system architecture and designed the security, communication, data-persistence and synchronization capabilities. SD3 also developed a client-side mobile application and database that interfaced with the server-side web services

The mobile application enabled the field technicians to receive daily job orders electronically and eliminated the need for daily visits to the office. The app was integrated with GPS, mapping services, turn-by-turn directions, and included customized data entry forms that captured real-time information. It also utilized Bluetooth technology for integration with a proprietary hardware device mounted in the technicians truck. Simultaneously, the operations team was provided with a robust web application that included features for scheduling, routing, and job review and approval. Additionally, a detailed geospatial map view was created for tracking the locations and viewing real-time information for the technicians in the field.

The outcome:

With applications and information at their fingertips, the clients desire to streamline the daily work process for their field technicians and use real-time information for immediate decision-making was achieved. The new tool improved their operations, increased revenue, and reduced costs. The mobile and central web applications also increased daily productivity for the technicians  a factor that ultimately allowed the company to pay for the development costs in the first year of operations.


Technologies used to develop this custom application include: Google Android, Java, RESTful web services using JSON, SQLite database, Eclipse IDE, Bluetooth, and GPS
