Jeff Teper, company vice chairman for Microsoft 365, has a imaginative and prescient for the corporate’s Workplace 365 chat-based collaboration device that competes with Slack, Fb’s Office, and Google Chat. When it comes to attain, Teper needs Microsoft Groups to eclipse Home windows. (Home windows 10 runs on over 1 billion month-to-month lively gadgets.)

Our interview came about a day after Microsoft concluded its online-only Construct 2020 developer convention, the place the corporate gave enterprise builders new instruments to construct Groups apps. Microsoft launched a Visible Studio and Visible Studio Code extension for Groups in preview, launched new integrations between its Energy Platform and Groups, and introduced a customized app submission course of to assist IT admins. Teper was joyful to cowl a spread of Groups matters, together with metrics, progress, opponents, shopper positioning, machine studying, and naturally coping with the elevated demand in the course of the coronavirus pandemic.

Groups is Microsoft’s fastest-growing enterprise app ever. That was true in 2018, lengthy earlier than lockdowns began juicing up numbers for distant work and studying. As of April 29, Microsoft Groups had 75 million day by day lively customers, up 70% simply six weeks prior. That month, Microsoft noticed greater than 200 million assembly contributors in a single day, producing greater than four.1 billion assembly minutes.

Metrics: DAUs and MAUs

That 75 million quantity encompasses individuals who use the Groups app day-after-day — hundreds of thousands extra doubtless use the app solely throughout weekdays, weekly, and even much less ceaselessly. In Microsoft’s most up-to-date quarterly earnings, CEO Satya Nadella mentioned the corporate had 258 million paid seats of Workplace 365, which incorporates entry to Groups. Meaning lower than 30% of Workplace 365 enterprise customers are utilizing Groups day-after-day (how a lot much less will depend on the variety of free Groups customers).

Microsoft has attributed this yr’s spikes in Groups utilization to the pandemic, that means a drop is inevitable. Nonetheless, given Workplace 365’s measurement, Groups has loads of room to develop, although Teper doesn’t fairly see it that method.

“I’m very bullish on us getting extra Workplace 365 customers to make use of Groups. But additionally, first line employees adopting Groups in well being care, in retail, airways, and so forth,” Teper mentioned. “It truly offers us a a lot larger addressable market than, say, the individuals who creator Phrase, Excel, and PowerPoint paperwork all day. So I feel we’ll see sturdy progress, tons of of hundreds of thousands of individuals utilizing Groups. In some unspecified time in the future, the proportion of time individuals are spending in on-line conferences has acquired to return down. So, the four billion day by day minutes, that can proceed to develop. However sooner or later, that quantity goes to degree off as a result of individuals don’t wish to spend eight hours a day in on-line conferences if they’ll meet in particular person. However so far as the customers, I’m very bullish on that’s going to proceed to develop.”

When Microsoft shares an Workplace 365 seats quantity together with a DAUs determine for Groups, it offers ammo to opponents like Slack. Why not escape what number of day by day lively customers Workplace 365 has to make an apples-to-apples comparability doable?

“Within the matrix of all of the issues we may disclose we’ve determined to maintain it comparatively easy. The rationale we determined to make the change for Groups is as a result of it’s a communication app,” Teper defined. “Individuals mentioned, ‘Hey, for communications apps, these issues are day by day habits. To ensure that us to know how properly you’re doing for Groups, it’s best to give the day by day lively quantity.’ We’ve truly had a cohort of people that need us to reveal the month-to-month lively quantity for Groups. That’s a much bigger quantity than the day by day lively consumer. However there’s monetary laws about materials disclosure and so forth, so I gained’t throw out any new numbers as a result of the SEC and Microsoft gained’t let me.”

Microsoft at the moment has no plans to share DAUs for Workplace 365 or MAUs for Groups.


Groups has dwarfed the competitors, based mostly on numbers shared up to now. Slack has 12 million DAUs as of October, Fb’s Office has three million paid customers as of October, and Google has but to share a quantity for Chat. We requested Teper which device he views as Microsoft Groups’ primary competitor. At first, he dodged the query.

“I used to be going to say pen and paper,” Teper mentioned. “I feel there’s nonetheless individuals doing issues that must be automated and digitized. I feel if we have a look at focusing on 1 billion, 2 billion individuals, a lot of them are doing issues in particular person, that’s costly. You’ve acquired to journey. They’re doing issues manually with pencil and paper. We actually see that in hospitals. So our largest competitor is remodeling how individuals work. That’s how we go huge.”

Google Meet has 100 million day by day assembly contributors and Zoom has 300 million day by day assembly contributors, which places Microsoft Groups proper within the center with its 200 million assembly contributors. (Not like day by day lively customers, “assembly contributors” can depend the identical consumer greater than as soon as.)

Addressable market

However Google Meet and Zoom are just for video conferencing. How does Microsoft view the aggressive house right here?

“First, we begin from a buyer standpoint,” Teper mentioned. “There are a billion individuals utilizing Home windows and Workplace, so clearly there’s a billion individuals who needs to be utilizing our cloud providers, cellular functions, and desktop functions. After which a part of the rationale we’re enthusiastic about Groups is that it may be utilized by people who find themselves concerned in enterprise processes who might by no means have been conventional Workplace prospects.”

Microsoft presents digital affected person consults in Groups. Medical doctors and nurses typically use Workplace, after all, however most of their day is spent speaking to sufferers. Microsoft hopes they’ll use Groups to collaborate with different well being care practitioners of their organizations in addition to carry digital discussions with their sufferers. Teper additionally envisions airways utilizing Groups to collaborate with upkeep crews and retail shops attempting to automate workflows.

“We take into consideration how many individuals on the earth we are able to empower with our instruments,” Teper mentioned. “We’re serious about tons of of hundreds of thousands and billions of individuals. Satya, when he got here in as CEO, mentioned ‘each particular person and group on the planet’ as a result of he needed us all to consider our mission and alternative and impression. We begin from there. After which we do this by constructing a collection of instruments, built-in in Groups for chat, for calling, for conferences, for recordsdata, and so on.”

“In order that’s the second half,” Teper continued. “And for positive, in these classes, there are huge opponents who’ve good merchandise, and we’re completely striving to be your best option in every class. So sure, individuals are very a lot selecting Groups over Slack. Our success is within the zone of Zoom, however if you happen to have a look at the commercial-business-and-education-only quantity which we produced — they’ve a variety of shopper numbers — I feel we’re doing very properly. So we begin from a buyer standpoint, we convey collectively a collection of instruments that no person else does. And every of these instruments must be better of breed and be chosen and liked by prospects in that class. After which the third factor, which is absolutely what Construct was about for us, which I feel is exclusive, is making all this a platform.”

Groups as a platform

Teper is referencing the instruments the corporate launched final week to assist enterprise builders construct apps for Groups. That’s the place he argues Microsoft’s built-in providing is in a “clear management place.” In different areas that Groups competes in, “it’s a little bit of a dogfight,” he concedes, however when it comes to a platform for builders, Microsoft is forward.

“Groups is a shell, a platform for constructing collaborative functions and integrating them in,” Teper mentioned. “And creating monumental alternative for companions to construct options for patrons and albeit earn a living investing in constructing their functions on Groups. We’ve had a 750% progress of apps inside Groups [over the last year]. Seeing options for well being care, training, manufacturing being constructed on Groups is that factor that I feel possibly not all people appreciates that we’re attempting to give attention to now. All the things from the Energy Apps assist to Visible Studio assist, how individuals deploy functions. That’s the massive factor that’s the recreation changer versus the alternate options within the business on the market. So we’re going to assist organizations clear up their particular issues, not simply give them basic goal instruments.”

From there, Jeff begins to dream huge. “That platform then turns into an ecosystem; very similar to Home windows grew to become an ecosystem, individuals construct on it. You get the community results and flywheel of that.”

Is that how Teper sees Groups? The following Home windows, if you’ll, for communication?

“I wouldn’t use these phrases precisely that method as a result of Home windows goes to be the subsequent Home windows,” Teper mentioned. “However it’s a platform that transcends working methods that might be even larger than Home windows. Sure. We would like individuals to construct Groups-based functions that run on iOS, Android, the online, the Mac, in addition to Home windows. So by that definition Groups might be finally, much more ubiquitous platform over time. It gained’t obviate the necessity for Home windows however …”

Groups for customers

The opposite piece of the puzzle in making Groups a large platform is increasing past companies. In March, Microsoft introduced that Groups for customers options have been coming to the Android and iOS app within the subsequent few months.

There may be priority for customers utilizing enterprise instruments. The most recent high-profile instance is Zoom — an enterprise product that buyers have embraced. Everybody understands why individuals wish to use video conferencing instruments, particularly throughout lockdowns. However what’s the attraction of a chat and collaboration device over, say, social networks, messaging apps, or simply plain texting that buyers use at this time?

“Virtually each Microsoft product that we’ve achieved — Workplace, Outlook, OneDrive, and so on. — as a result of we’ve supplied it to individuals throughout work, faculty, and their private use, they’ve been actually profitable,” Teper mentioned. “Not all people of their private life is constructing big Excel spreadsheets, however tons of of hundreds of thousands of individuals are, to handle soccer groups, dwelling enchancment, maintain observe of their funds, athletic coaching, and so on. So, we’ve been very profitable in constructing merchandise for work and life. We do suppose that there are groups in your private life. There are sports activities groups. There are households. There are spiritual teams. There may be working a charity public sale, and so on., and so on. And we don’t suppose these team-based actions in your private life are properly served by doing them on public social networks, or simply in chat. We expect, as soon as issues get a little bit extra structured, you need a structured device to assist on it. And so we’re introducing Groups for that.”

Constructing a product for each enterprises and customers on the similar time brings its personal set of challenges. There are additionally benefits although, as Teper identified.

“We’re additionally recognizing, as we’ve achieved with Home windows and OneDrive, that whereas the core product needs to be the identical, we actually ought to streamline it for these shopper eventualities,” Teper continued. “And by doing that, we’ll make it higher for everyone. A part of the work we’re doing within the subsequent few months as we prepare to begin with Groups for customers, first on cell phones, is to streamline the expertise. However I feel if you happen to’re doing any type of structured exercise that’s not an advert hoc dialog, Groups goes to be a better option than an current chat product or social community. We’re not attempting to displace all that. We’re simply saying there’s an unmet shopper want in these extra sophisticated actions in your private life the place getting organized is helpful, identical to it’s with OneDrive or Excel.”

Microsoft Groups for customers will naturally intersect with Skype. We go over Teper’s ideas on that overlap right here: Microsoft guarantees new Skype options regardless of Groups for customers launch.


When enterprise customers began more and more working from dwelling, Groups utilization spiked. There have been even reliability points. We requested Teper what it took to deal with that demand past merely spinning up extra cloud cases.

“Groups already, earlier than COVID-19, was our quickest rising enterprise,” Teper mentioned. “So we have been used to nonlinear progress. However then post-COVID-19 it went off the pattern line. The Groups structure and the issues behind it, like SharePoint and the Microsoft Graph, are elastic. So, as we noticed a brand new demand, we wanted to simply spin up extra Azure capability all over the world. And there was undoubtedly a variety of pleasure, again within the first couple weeks in March, as a result of we have been doing that. We discovered a number of bottlenecks. When you’ve a large-scale system, we had a number of issues to tune, which we did. Via this it’s been fairly clean crusing. The one stat I share is the variety of day by day assembly minutes is about 20 instances what it was after we began. I’m fairly pleased with the workforce that constructed the software program that might scale 20X. Sure, we needed to spin up a variety of Azure capability for it.”

Some code, such because the provisioning system for including new accounts to Groups, required remodeling. The corporate had merely by no means anticipated including as many customers per day because it did in the course of the lockdowns. Fortunately, Microsoft didn’t have to show any organizations or customers away. However the firm did alter the way it predicts utilization.

“In the beginning of this we had a gathering — each three days, that went to twice every week, after which as soon as every week (now it’s form of each couple weeks) the place we might have a look at all of the indicators,” Teper mentioned. “We’d have a look at the utilization depth of our current prospects. We had tons of people that had licensed the product who have been utilizing it extra. We regarded on the signup price of recent prospects.”

In a single case, a faculty system instructed Microsoft that 800,000 college students could be exhibiting up on Groups the next week. The workforce had to have a look at its datacenters close to these customers to ensure there was capability. At first, the Groups workforce was speaking to the Azure workforce day-after-day about the place capability would doubtless be advantageous and the place it wanted assist.

Amassing information

That was then. Now, the corporate has sufficient information to make smarter selections.

“After which as we acquired most likely a pair weeks into this, our information scientists acquired sufficient information to begin to mannequin a forecast,” Teper mentioned. “The primary week you’re form of going off anecdotes. Inform us about all the faculties and massive prospects. We’d stroll by them. And it was a little bit little bit of conjecture about ‘Will each pupil present up? Or simply most of them? Or a few of them?’ And so after a few weeks we had sufficient information the place the brand new fashions grew to become very dependable once more. So we didn’t need to over-provision. At the start after we have been stunned by the demand, we swung the pendulum so as to add a variety of capability for the acute case eventualities. That was largely what performed out. You don’t wish to function that method eternally as a result of you’ll be able to over-provision.”

That’s not a simple stability to strike.

“We spend billions of a yr constructing out our information facilities and including capability,” Teper continued. “If we under-build for the peaks, our prospects wouldn’t have an incredible expertise. If we over-build, our shareholders wouldn’t have an incredible expertise. Sure, we forecast this very fastidiously and have conferences. There’s form of a gathering each month that I’m going to with my friends to ensure that we’re very safely within the zone of demand that we predict we’d forecast. However once more you form of design your methods for black swan occasions. We had not modeled 20X progress in assembly minutes in 1 / 4. We wrote the software program that was prepared for that. We acquired a variety of nice assist from our Azure associates. We talked a few black swan state of affairs, but it surely wasn’t in our mannequin.”

In the present day, Teper is snug with the workforce’s capacity to foretell demand, despite the fact that “new customers are nonetheless coming to the service at a sooner price day-after-day. We’re again to, for lack of a greater time period, ‘regular mode’ the place we’re not assembly each couple of days to have a look at the information. It’s not altering as a lot because it was in the beginning.”

AI for guidelines and options

Early on, the corporate would measure the variety of PCs and other people as “nations have been hit at completely different charges with COVID-19.” Amassing all that information let Microsoft construct ML fashions to foretell how organizations may enhance their depth of Groups and when work-from-home guidelines could be set.

“Extra customers present up, there’s extra conferences, individuals do extra duties per day, and we construct fashions on that,” Teper mentioned. “We make a set of predictions after which we study and there’s a suggestions loop. Then there’s a second mannequin of when do organizations come up below the service. As a result of there you’ve a gross sales pipeline that you simply speak to salespeople on, however you actually wish to validate that. So we constructed this separate set of fashions there.”

Microsoft makes use of these algorithms to assist it forecast each the expansion of Groups and monitor for points.

“We used to jot down guidelines to watch our software program,” Teper mentioned. “We now use ML to do this. As a result of for instance, if we’ve a spike in assist incidents, we’ll use machine studying to correlate that with telemetry we see in our servers all over the world. And the machine studying will then write guidelines of patterns for us to detect. Because of this our service reliability has gotten fairly nice by all this. I really feel very pleased with our machine studying based mostly monitoring.”

AI use doesn’t finish there. “The most important give attention to AI is definitely within the product,” Teper mentioned. VentureBeat has lined Groups’ varied AI-powered options — most lately, we went deep on how Microsoft Groups will use AI to filter out noise from video calls. However Groups additionally makes use of AI to floor related dialog notifications and produce dwell captions of conferences. And there’s extra within the pipeline.

“We even have an effort referred to as moonshots, that are form of huge, loopy, bolder issues we’d love to do in Groups,” Teper mentioned. “If even one out of 5 of these repay, we’ll have some fairly superb issues within the subsequent couple of years.”
