Background 

A. Datum Corporation manufactures electronic measuring equipment that is sold worldwide. The equipment requires periodic inspection and calibration by a team of inspectors. The equipment supports near field communication (NFC). 

Inspectors currently receive daily email messages that list the locations they must visit that day and the equipment they must inspect calibrate, or update. To request schedule changes, inspectors must call, fax, or email a support center. 

A. Datum plans to develop a Windows Store app that connects to a scheduling application hosted in Microsoft Azure. The app will allow inspectors to view client information, equipment information, and other documentation. Inspectors will use the app to report inspection results back to the company's Microsoft Azure application. 

Business Requirements 

Inspectors must be able to use the app to perform the following equipment-related tasks: 

.... 

Gather information about each piece of equipment during inspections. 

Update equipment software and firmware during inspections, 

Identify missing and outdated equipment. 

Submit orders for replacement equipment to the customer support team. 

The app must support the following scheduling requirements: 

.

When an inspector signs in to the app, daily schedule and task information must 

automatically download to the inspector's Windows device. The information must include client locations, equipment inventory at each location, and equipment settings. The files contain sensitive and proprietary information. 

. Inspectors must be able to request a list of other clients within a Specified search distance who might requirelocation, and equipment settings. The files contain sensitive and proprietary information. 

. Inspectors must be able to request a list of other clients within a specified search distance who might require equipment inspection. . Inspectors must be able to refuse a task and remove it from their schedule. 

Technical Requirements 

File Download, Storage, and Security .

Inspectors must be able to search for equipment software and firmware updates stored in their OneDrive folders. . Downloaded files must be enrolled in selective wipe and made unavailable eight hours after download. . The app must use background tasks to download files to the users' devices. . All content files downloaded for the inspectors use must be available for searching in the app. . All data transferred by the app between the Windows devices and the Microsoft Azure application must be secured and encrypted. 

Equipment Interface and Connections . While the app is connected to a piece of equipment, inspectors must be able to simultaneously display the app and the content of their OneDrive folders. . The user interface must include a slide control that allows the inspector to specify a search range for nearby clients. . Inspectors must connect the app to any piece of equipment by using a tap connection.
