A new partnership with SAP sees that company building a series of bots to provide conversational interfaces with various products. The first three are for the Concur travel and expense management system, SuccessFactors (human resources), and the HANA Cloud platform (integrating the SAP Web IDE with Slack channels).
"Whether physical or digital, our teams expect workspaces that empower them to communicate efficiently, connect and ideate easily, and build new products quickly - wherever they are - and Slack is a great example of how they want to work," said Capital One vice-president of workforce technology, Jennifer Manry.
"With Enterprise Grid, Slack has preserved the sense of community, interactivity, and humanity of the workspace that our teams love, with the administrative capabilities we need as a larger enterprise."
Slack has previewed a number of forthcoming Enterprise Grid features including universal search, faceted search (to quickly filter and refine searches), prioritised reading, channel highlights, and daily briefings (to provide a single, streamlined view of your most important and relevant messages).
