After Moving to Slack: Inbox Zero (at least twice per week)

TL,DR Version: Moving my entire Engineering organization to Slack and adopting a ChatOps collaboration mindset has reduced email volume over 95% and now enables us to resolve issues in 1/4th of the time.

I have always been a fan of using automation, web hooks, and chat-assisted operations to streamline work and enable collaboration across different locations. However, this traditionally required some Engineering and Operations (i.e., DevOps) investment in setting up collaboration servers, programming bots, etc. Slack has changed this, virtually eliminating all technical friction of moving to a ChatOps model. Here is our of how Slack enabled us to move to a ChatOps environment with far less email, faster response times, and greater overall productivity.

In late 2013, I joined a new company that—at the time—had no one on staff at the time with a DevOps-style background. After coming from several years of Chat-integrated operations, it felt like hitting the brakes. One night a few weeks later, I saw a Tweet by @mparca on February 9 about this new great service called Slack. I took a quick look and realized I could achieve everything that HipChat and Hubot did—with a simple push-button SaaS service. My initial set up (our organization, some channels, and hooks to Github) took less than 10 minutes. As it was free (for many features), I did not even need to process a Purchase Order (even better). I was off to setting ChatOps at a new place.

Initially, things went pretty slow. At the time, most of our tech stack and tools were hosted on-premise. Our chat tool of choice as a Skype (not a hook-friendly app). I got a few people to move to Slack, but not many.

Over time, as we implemented a full continuous integration and deployment chain, we added more and more hooks into Slack. First came a move to Atlassian (Cloud). Next Jenkins. Next Sentry. Then Ansible. Then Icinga. Then came custom RTM scripts for more complex things, such as letting our Data Scientists know they have left an idle PySpark context running for more than eight hours. What made this so easy was that everything but the custom RTM scripts could be done in less than five mouse-clicks (it is very helpful that so many collaboration and monitoring tools have enabled web hooks).

As we added more hooks, and started to bring more people onboard, I noticed an interesting shift. People joining our team began to just use Slack to communicate. One developer would come across an interesting new open source repo or article and share it with the rest in #general. Developers with DevOps privileges would jump on issues as soon as they saw a Sentry alert in #prod (saving the need to even text or phone the on-call engineer). Some people even answering questions in code review while they were doing things like waiting at the airport to depart on vacation.

Today our Engineering Teams (Product, Hardware, Software, Data, and Ops) all now primarily use Slack for communications. Most even use it in favor of texting. We Slack each other tickets that are ready for work, UAT, or release). We use group chats to have conversations to answer questions about stories, designs, bugs, and more. We use Slack channels integrated with Github for better code reviews. We use Slack to facilitate pair programming (and pair testing). Slack is now our default tool  for issue diagnosis, as sharing log messages, code snippets, and JSON is much clearer thanks to native markdown.

We achieve this with the following channel model:

  • One channel for each environment (so we can let people know if we are about to add nodes, run a load test, etc.). We have our respective Jenkins, Ansible, Icinga and Sentry hooks tied into each environment channel as well.
  • One channel for each code repository (to see PRs and conduct code reviews). We have aligned our JIRA projects with these to integrate tickets as well.
  • We have some basic team channels for more focused group conversations
  • We also have a #rm channel for simple-to-read log of what was released, when

As our organization moved to this model, life and work got easier in some rather visceral ways:

First, I have been able to dial down my notifications to only ping me when four things happen: I get a call, I get a text, I get a direct Slack message, or there is public Slack in a mission-critical channel. I no longer get endless interruptions, making me more productive at work (and more attentive in meetings and at home). If my phone does ping, it means there is something very important—which actually lets me react to these issues faster.

Second, my email volume is down over 95%. The bulk of the emails I now get are related to true business questions (vs. endless status messages and FYIs). As a result, I can answer email faster and now regularly hit “Inbox Zero” at least twice a week—while managing a 24x7xForever SaaS Engineering organization with follow-the-sun development and operations spanning California, Washington, Europe, and Asia.

Our full embrace of Slack did not happen overnight. It organically evolved over a period of about 18 months–a natural rate of adoption for organizational change. Because it was organic, we did have to institute policies  that forced usage. Instead we allowed our teams to naturally adopt Slack in ways that made work easier. I hope more organizations can make this transition as everyone could benefit from less email and fewer interruptions.

Natural adoption of Slack over other forms of communication would have happened if the usability was not as good as it is. One of my favorite features is how well Slack detects when I am no longer at my desk: if I walk down the hall, my phone chirps on key Slack messages; when I sit back down my phone stops and my laptop takes over.  This happens within seconds.

Oh BTW, we do all of this with the baseline free Slack account. That’s one less excuse to not give it a try.

How to Architect for IoT

Last week I had the pleasure of doing a podcast with Forbe-contributor Mike Kavis on how to architect for the Internet of Things (“IoT”). We originally connected on Twitter regarding a discussion on whether the IoT and sensors are Big Data. That discussion led a podcast on architecture challenges–from device to data to data consumer–created by the onset of millions (or billions) of connected sensors and smart things.

Here in an excerpt of what we discussed

  • Connected devices bring back some classic engineering challenges back into the forefront.  How do you transmit data securely and with low power consumption? How do you handle lossy networks and cut-off transmissions?
  • Not everything is smartphone app transmitting JSON over HTTP (that would be cost prohibitive from both a hardware and bandwidth perspective). How do you handle communication myriad protocols, each of which could be using a near-infinite variety of data encoding formats?
  • IoT data is messy. Devices get cut off in mid-transition (or repeat over and over until they get an acknowledgement). How do you detect this–and clean it up–as data arrives?
  • IoT data is of incredibly high volume. By 2020, we will have 4x more sensor and IoT data than enterprise data. We already get more data today from sensors than we do from PCs. How do we scale to consume and use this. In addition, connected devices are not always smart or fault-tolerant. How do you ensure you are always ready to catch all that data (i.e., you need a zero-downtime IoT utility)
  • IoT and sensor and of itself is not terribly useful. It is rarely in a format that a (business or consumer) analyst would even be able to read. It would be incredibly wasteful to store all this as-is in a business warehouse, DropBox repo, etc.
  • IoT and sensor data needs context. Knowing device Knowing that FE80:0000:0000:0000:0202:B3FF:FE1E:8329 is at GPS location X,Y is of no use. You need to marry it to data about the “things” to get useful insights.
  • IoT data simultaneously “lives” in two points of view: what does this mean right now and what does this imply for the big picture. The Lambda Architecture is an ideal tool to handle this.
  • Finally, while all the attention is on the consumer stories, the real money is the Industrial and Enterprise Internet of Things. It’s also where smart things are far less creepy.

I also want to take a moment to extend a big thank you to the folks at Cloud Technology Partners, SYS-CON Media, and Cloud Computing Journal for sharing this podcast.  I also want thanks to all of you on Twitter who retweeted it. I was happily overwhelmed by the sharing and interest!
