Business process professionals are starting to see more choices in how they and their organizations can investigate and buy enterprise resource planning (ERP) apps, add-ons, and complementary software. Dedicated websites, dubbed "app stores" or "app marketplaces," are emerging as an additional ERP app showcase and/or purchase channel option. Business-focused app stores are also set to serve as new kinds of internal and external engagement hubs between end user and vendor communities. Business process pros should use ERP vendor app stores as a model for internal app distribution as they look to better administer their employees' consumption of apps.
