Onboard new teammates with a 90-day plan


My new boss had written up a 90-day plan for me the week before I started. This was perfect timing. I was already starting to put a bow on my current work and my focus was wandering. Now my brain could start working on ideas for the next gig. Plus, I had a much better idea of what I’d start working on and how to make an impact than I did coming out of my interviews. It was one of the better emails I’ve ever received.

It seems totally obvious that hiring managers should have a plan for new hires. Yet, in more than a decade of work and several jobs, I’d never had a 90-day plan for a new position. In the parlance of our times, a 90-day plan for new team members is one weird trick that is pretty dang easy to pull off.

For all my hires since then, I’ve written up a 90-day plan. I’m convinced that this is one of the best things a hiring manager can do to bring new people onto their team. And it’s relatively easy!

A 90-day plan for onboarding starts off with very specific tasks for the first day and week. Do the paperwork, meet the people, get your digital and/or physical workspace set up. Learn about the team’s process, the rhythm of building and delivering. Meet with a team buddy who will introduce you to folks on the team and explain all the quirks and features of how the team works.

The first 3-4 weeks of a 90-day plan, for hands-on engineers, is about working with a buddy to spin up the flywheel. The goal is to come up to speed on learning the systems and contributing to them. Get the system running on your laptop or development sandbox so you can make quick iterations and one-off experiments. Land your first code change, your first review, and your first change to production.

(My angle here is for folks building SaaS web applications, but it’s the same for any kind of developer: get a few early wins and build from there.)

The second 30 days are when new team members start to come into their own. This is when I want to help my new teammates plant the seeds to realize the potential I saw when they interviewed. Important projects start spinning up. Strategy comes into play. Now is when I re-emphasize to them the potential I saw and brainstorm how to put that special skill, innate talent, or superpower to work improving our team or outcomes.

The final 30 days should start showing evidence that my new teammate is creating good outcomes. The seed of what makes them special (and what compelled me to hire them) is planted and starting to take root. I should be able to talk to teammates and co-workers and hear about how this new person is making an impact on our work and the company’s trajectory.

After 90 days, my new teammate should feel like a productive part of the team. At every point in those first 90 days, they should see little hints that they belong with this group of individuals making a thing together. After 90 days, they should feel confident that they do in fact belong with these folks and made a great choice when they accepted our offer.

Writing a 90-day plan for new hires forces you to think through how to get them started. You won’t just throw them in the pool and say “good luck!” And, it tells your new hire that you’re a smart person who is invested in their success. Every leader should do this.

Use a tag line that means something

I like that Ember’s tagline is about ambition.

It’s easy to write an empty, temporary tagline. “Simple and good”. “Only 4 kilobytes.” It’s harder to write a tagline that generates principles which stand the test of time. “Simple and fast” are in opposition. “Only 4 kilobytes” is unlikely to last if the software evolves.

“Ambitious” as a tagline speaks to a number of qualities, but none of them are in conflict. An ambitious project could choose the boring tactics in favor of rapid delivery. Another ambitious project could aim for longevity. Yet another ambitious project might aim to have a large impact in the world or aim to do something previously considered implausible.

For a framework the size of Ember, that’s an appropriate diversity of goals. But they’re all covered by ambition. The tagline unifies and clarifies as much as it inspires.

Use factories to create jumbo object graphs

The entire time I’ve been using FactoryBot, several years at this point, I’ve used it one factory at a time:

company = create(:company, name: "Acme, Inc.")
alice = create(:user, name: "Alice Smith")
posts = create_list(:post, 3, user: alice)

Do you see the mistake I make all the dang time? Spoiler alert, I forgot the company relation on Alice’s user, so she is either orphaned (unfortunate) or created on an entirely unrelated company. That’s gonna make my test fail in weird ways!

Lately, I’ve been trying something different: create the whole object graph I want to test on in one fell swoop:

company = create(
  :company,
  name: "Acme, Inc",
  user: build(
    :user, 
    name: "Alice Smith",
    posts: build_list(:post, 3)
  )
)

The entire intent of the test scenario is made clear right here. And, the error I so often make is solved structurally rather than by vigilance.

Granted, that’s pretty chunky and way more lines. I feel like it’s a worthy tradeoff!

When I need to reference the models created by my jumbo object graph, I use RSpec let and ActiveRecord finders with a mind towards consistently finding the right thing:

let(:company) do
  create(...) # the whole company bit from above
end
let(:alice) { company.users.find_by(name: "Alice Smith") }
let(:posts) { alice.posts }

Failure = entropy due to adding humans

Here’s a real dinger of a sentence from Michael Lopp’s latest, The Art of Leadership: Small Things, Done Well:

Failure is created by the increasing entropy of a growing number of humans running around the building, good intentions in hand, breaking things.

Growing an organization requires rethinking trust, coordination, and collaboration. The breakpoints where things go from working pretty well to an absolute shamble come faster than we think. They don’t even occur at nice, round numbers like base–2 or base–10 orders of magnitude.

Figuring out how this works for teams, companies, social networks, and whole countries feels like one of the big unsolved problems of the knowledge/attention-era.

Writing is thinking, so write about code

Writing clarifies thinking. Therefore, writing design docs clarifies one’s thinking about code. Design Docs at Google and an example/meta design doc from the same author are great places to start!

I found that writing prose until I run out of clarity and then switching to proof-of-concept code is even better. The constraint of making an ambitious design work with a minimal change-set is a nice way to work for a day or so.

Lots of features or fixes don’t require in-depth thinking to get started. But when they do, sorting out the ideas and tradeoffs in writing helps a lot.

Write until I run out of ideas, flesh those ideas out, write about the nuances I found. It’s a nice feedback loop!

Bradford Fults on feedback and human bias

A Better Approach to 360° Feedback: Bradford Fults shares ways to route around fallible human memory and gather useful information when it comes to review season.

Humans also have a recency bias and suffer from long-term memory distortions that change to fit their current opinions of other people. This means that “observations” from months ago often aren’t so much observations as they are current opinions and emotions repackaged as fixed stories about the past. Most people don’t even intend to distort the truth like this: it’s just the way the human brain works.

Instead, ask questions in the context of how the reviewer works with the reviewed, particularly in the last 90 days or so. Paraphrasing Janet Jackson: “What Have You Done For Me Lately?”

Towards smaller JavaScript

The JavaScript ecosystem’s gone to a strange place where dense frameworks and complex tooling are the status quo. But, there are data-points suggesting the pendulum could swing back sooner than later:

  • Snowpack 2.0 – download all your deps, import them as modules. Snappy development experience ensues.
  • lit-html – generate DOM without going through React/Vue/etc. intricacies
  • Alpine.js – attach dynamic interactions to elements with data elements describing DOM manipulations
  • htmx – attach dynamic networking to elements with data elements describing AJAX/Websocket/SSE events

Caveat: I haven’t tried any of these. But, the trend-line is promising. JavaScript the language, while not perfect, is Pretty Good now. Perhaps the next few years will see the great ideas of the frameworks squeezed into more accessible, less sprawling expressions of those ideas.

The possibility of software through the ages

The gestalt of what’s new in software and how it’s changing our world has evolved over the decades.

In the ‘90s, it was “don’t make me think!”. User interfaces went from text-based systems that required memorization and expertise to graphical systems that afforded more casual use of computers. Unix users and their terminals are a notable holdout to this day.

In the ‘00s, it was “don’t make me remember!”. The internet let us to stop worrying about access to common knowledge. Search engines, news feeds, e-commerce, and listing sites made it pretty easy to answer many questions without a resident expert. Nascent social platforms made it possible for our “friends” to feed this information back to us. Notable holdouts: it was impossible for me to search for punchlines from SNL skits, and largely still is.

In the ‘10s, it was “don’t make me describe the content I want to see!”. The now-giant tech companies figured out that their products were more “engaging” if they pushed content to people instead of people clicking around and typing queries to describe what they want. Thus was born machine learning, recommendation systems, and infinite/algorithmic feed scrolling. Notable holdout: none, the blast radius of ad-tech is wide and far-reaching.

From this particular moment, it seems like the ‘20s are going to be “don’t make me leave my enclave”. Even if there’s a breakthrough in medicine and this pandemic is a temporary blip, the writing seems like it’s on the wall. Many kinds of service and retail commerce we used to go out into the world to interact with, along with offices, are going to fade away as climate changes and viruses come and go. Notable holdout: the not-so-middle class folks who do the machine’s bidding and keep the wheels of commerce rolling.


Over three decades, things are at once noticeably better and yet there’s vast room for improvement. If you’re wondering where impactful work can be done in technology, it’s in making the benefits of the technology we’re building for the middle/upper classes today available to the less fortunate tomorrow. If we can make fantastic televisions available to everyone, surely we can improve the outcomes that matter most in everyone’s lives.

If we could bend this curve, the ’20s could be the decade of “no pithy quote, just people helping their neighbors.”

The Revenge of the Intuitive and developer tools in 2020

The Revenge of the Intuitive – Brian Eno lamented the downsides of a modern, computer-based recording console. Twenty years ago! The trade-offs for “freedom” at the expense of human affordances were too much for Eno at the time.

Feels like we’re in a similar spot with developer tooling. It works for the most accomplished and persistent of us. For many people who would like to build software, it’s too much. It’s too easy for our castles of complexity to thwart the novices.

The trouble begins with a design philosophy that equates “more options” with “greater freedom.” Designers struggle endlessly with a problem that is almost nonexistent for users: “How do we pack the maximum number of options into the minimum space and price?” In my experience, the instruments and tools that endure (because they are loved by their users) have limited options

You could just as easily write this today about software development libraries and tools. Too many of them discard pretty good ideas about how to build applications. Too much fascination with meta-tooling. Not enough thought put into how to put applications in people’s hands.

With tools, we crave intimacy. This appetite for emotional resonance explains why users – when given a choice – prefer deep rapport over endless options. You can’t have a relationship with a device whose limits are unknown to you, because without limits it keeps becoming something else.

We need standalone tools and libraries to build upon. However, well-curated, opinionated developers tools are where the magic happens. Frameworks like Rails, Tailwind, Next.js are where the leverage is.

A determined expert can build an application from building blocks. Novices can at least get started with a well-crafted framework. A good community and forgiving documentation can get them through the valleys of confusion to the peaks of accomplishment.

Perhaps low/no-code tools will bring the benefit of the “golden, narrow path” to more people. Maybe the trade-winds of developer tooling will blow away from showmanship back to accessibility. Either way, we should tidy up our house and make software development more welcoming to those who aren’t already monks in the monastery.
