Exactly 12 years ago, the executives at a brand-new startup called Andela made a business-altering decision. Andela’s working model was built around recruiting and training promising African engineers and then place them in Western technology companies. However, since its employees and clients were spread across multiple time zones, the company needed an easy way for its distributed workforce to collaborate and make decisions asynchronously. So Andela turned to Slack. And it worked big time. As Andela expanded, Slack evolved from a simple communication tool into its central nervous system. It was the place where work happened and decisions were made. It shaped the company’s culture.

Before it became the connective tissue of entire organisations, Slack was already doing a lot of heavy lifting across everyday work. Companies used it well beyond simple messaging. Here's how that looked across five key areas.
Slack replaced lengthy email chains with real-time communication. Teams connected instantly and shared updates across dedicated channels without cluttering inboxes or working in silos. They created channels for projects or departments. They also used @mentions to reach specific people and kept side conversations organised with Threads.
Slack kept project teams aligned in one place. Teams discussed projects, planned schedules, shared files and updates, and tracked progress without switching between tools. They used Huddles for quick live discussions and Clips for fast feedback. Slack Lists also helped teams organise and prioritise important tasks.
Slack helped remote teams stay connected beyond work. Teams created channels around shared interests, from football to movies. They used polls, GIFs, weekly conversation prompts, or virtual coffee chats to encourage casual interaction. These small moments helped build stronger relationships and a sense of community across distances.
Slack made customer support faster and more collaborative. Companies organised support channels into sections such as Ticket Management or Billing Support for easy access.
Integrations with tools like Zendesk and Freshdesk brought customer tickets into Slack.
Teams organised files, links, updates, FAQs, and resources in dedicated channels. They used search to quickly find information from past conversations or shared documents. They also pinned important messages and resources so that everyone in a channel could easily access them when needed.
Slack has since outgrown its original role as a messaging tool. The companies getting the most out of it today are actually rethinking how work itself gets structured. Here's how five organisations have redesigned their operations around it.
Slack ran this experiment internally before recommending it to customers. Teams piloted no-meeting Focus Fridays and Maker Weeks, canceling all internal recurring meetings, with some teams swapping them for asynchronous status check-ins on active projects and others skipping the check-in entirely that week.
Consulting firm Booz Allen Hamilton uses Slack to streamline incident management, automate cross-team communications, and cut the noise so that engineers can focus on solving urgent problems instead of relaying updates. This isn't unique to tech firms. Slack has hosted panels where specialists from telecom company T-Mobile and an emergency medical services agency based at Rensselaer Polytechnic Institute both described using Slack to coordinate the people and tools needed to resolve incidents.
Australian delivery company Sendle rebuilt its collaboration model entirely around asynchronous Slack use. Chief people officer Nicole Olver has described how Slack is used "wall-to-wall" across the company. It eliminates the need for meetings scheduled at inconvenient hours across time zones. The shift changed how the team thinks about deep work versus real-time collaboration. Materials get shared for review in Slack first and meetings are reserved for resolving open questions rather than presenting information.
Rather than mandating a 9-to-5, Slack's own people team restructured the workday around a shared window of real-time availability. The company adopted the concept of "core hours," a roughly four-hour block in the middle of the day when colleagues are expected to be available for meetings, while outside that window people are free to work and collaborate whenever suits them. It paired this with a hard rule for video calls, a "one dials in, all dial in" policy, driven by the belief that meetings should be fully distributed rather than half-remote, half-in-room.
Delivery platform Shipt (owned by Target) redesigned how it works with external retail partners. The company runs 149 dedicated Slack Connect channels to communicate and collaborate directly with retail partners including Target, Sephora, Walgreens, Meijer, and H-E-B. Engineers on both sides use these shared channels for real-time technical troubleshooting instead of routing issues through email or ticketing systems. This shortens the path from "something's wrong" to "it's fixed."
Redesigning how work happens is only half the picture. None of it holds up without discipline at the channel level. The high-performing organisations above pair their bigger structural changes with a consistent set of ground rules that keep Slack usable as it scales. Here's what that looks like in practice.
Ask employees to use real profile photos and keep work discussions in public channels only. Tell them to use private channels only for sensitive topics. For example, if your team member posts “The launch is delayed” in #project-alpha, all replies should stay in a thread rather than filling the channel. The rules for feedback are simple. Praise someone in #team-marketing. Take criticism to @someone.
One channel. One purpose. For example, use #announcements for company updates and #team-sales for sales discussions. You may also have channels such as #social-books or #social-football for casual conversations. For customer-facing teams, keep internal discussions in a separate channel. Do not mix them with customer messages.
#team- can help identify departments, #proj- can help with ongoing projects, #cust- for customer channels, #help- for support requests. And so on. A channel description should also make its purpose clear. For example - “For website redesign updates only. Post new topics in the channel and replies in threads.”
Set aside a little time each month to clean up Slack. Archive channels such as #proj-product-launch once the project is over. Merge duplicate channels and update outdated descriptions. Assign an owner to each channel so that someone is always there for keeping it useful. For larger teams, include a quick request before creating a new channel so that you can avoid channel sprawl.
Reserve @channel and @here for genuinely important updates, such as a production outage or urgent company announcement. Employees can mute low-priority channels such as #social-books and check them when convenient. Set different response expectations too: a support channel may require a response within an hour, while #general can wait.
Redesigning work around Slack is about wiring it into the systems you already rely on, like Salesforce. This makes sure that channels reflect live deals, cases, and approvals instead of static conversations. This is where a Salesforce consulting partner like Brysa comes in.
We work with growing teams to connect Slack and Salesforce properly from day one: mapping channel structure to real workflows, setting up record notifications, and training teams so that adoption actually sticks. Our Salesforce Slack Quick Start package is built exactly for this. If your team is ready to move beyond ad-hoc channels and turn Slack into a real operating layer for sales, service, and operations, get started with this package and see how fast the shift can happen.
