Simplified app creation
PowerApps is a platform by Microsoft within the Office 365 suite, which gives you the power to create your own applications, which can be accessed internally by your company. You might use this to create a mobile form for data entry on-the-go, or a simple app to handle aspects of your business, such as time sheets.
PowerApps makes app creation simpler, but still requires some know-how and training. The language written is similar to Excel functions..
PowerApps can connect into almost any data that is in your Office 365, including Outlook emails and calendar appointments, SharePoint lists, and Dynamics CRM records. From that foundation, you can build a wide range of applications for just about any business purpose.
Simplifying a role's responsibilities into a single PowerApp can be a great way to help make work simpler and more clear for that person.
