The Azzier iOS Mobile App: Full-Featured; Easy to Use Interacting seamlessly with other plant floor software, it allows workers to add and update Work Orders, review the tasks to be completed, add time and materials, take pictures, and finally close the work order and add completion remarks. Elapsed time to complete the work order can also be tracked via the app’s timer, which records and timestamps it with the date each was performed. The barcodes feature makes it easy to identification of Assets. In essence, all app functionality is designed to streamline workflow management, timekeeping and other requisites of efficient plant floor operations. Workers can perform tasks on the go without returning to a stationary workstation throughout the day to input data. In addition, the app’s built-in integration with other CMMS components creates a unified experience for users. With today’s workforce already accustomed to mobility in their personal lives, adoption becomes effortless. By using a solution like the Azzier iOS Mobile App, firms gain the benefits of a highly functional CMMS mobile application. Outcomes management can anticipate include: · Increase Overall Productivity · Promote Cost Reduction with Increased Efficiency · Gain Faster Access to Critical Information · Boost Maintenance ROI · Foster a Competitive Edge Plant Floor Mobility: The Clock Is Ticking There has never been a better time for plant management to implement a software-driven mobile productivity app. A Cap Gemini survey found that 40% of the workers who say tasks could be done using mobile are currently not using mobile devices for these tasks. Furthermore, this lack of access to mobile devices is incenting workers to take matters into their own hands. In 2019, research firm Deloitte determined that in many locations, nearly half of workers have begun using their own devices for company work, operating outside the corporate environment. That makes it impossible for companies to ensure consistency of information recording and capture across the plant floor. It also makes it cumbersome — if even practical —to aggregate the data for corporate-level reporting, one of the most significant benefits of plant floor mobility. All of those concerns evaporate with the Azzier iOS app. When manufacturers provide a feature-rich software application to run on devices, whether corporate-issued or worker-owned, they eliminate issues of hardware functionality and compatibility. All workers experience a ubiquitous interface that allows them to retrieve and input information. In short, moving to facility-wide mobile adoption, and taking it all the way to mobile productivity, doesn’t have to be as complicated as it might appear. In our development of our CMMS mobile app, we identified numerous ways to simplify the process.
