Opportunistic Agile

I recently came across Martin Fowler’s article on “Opportunistic Refactoring”:

If you don't spend time on taking your opportunities to refactor, then the code base gradually degrades and you're faced with slower progress and difficult conversations with sponsors about refactoring iterations.

From the beginning I've always seen refactoring as something you do continuously, as regular and indivisible a part of programming as typing if statements.

This made me think back on all the times I’ve blogged about this spirit of doing things opportunistically in the process of developing software.

From Opportunistic Programming, to the Boy Scout Rule, and If You Can Lean You Can Clean, I see a common thread.

The “just-in-time” spirit of Agile is opportunistic. Doing things when they’re needed, not before, not after. And capitalizing on the bits of value that are in front of you right now.


Some Thoughts on QA

A recent comment on Hacker News got me thinking about the role of QA people in software projects…

To quote Dodge (via Deming), "You cannot inspect quality into a product."

It doesn't matter how great your QA team is, if the quality isn't in the system the QA team can't put it there.

I’ve seen time and time again where managers become concerned about the low quality of the software their organization is producing, and deduce that the answer to their problem is to assign more QA people to the project, as if the lack of QA people is the reason for the low quality.

There seem to be some misconceptions about QA that I wanted to write a few notes about:

  1. Testing of software should be at least 90% automated. The manual part is “exploratory” testing.
  2. A corollary to #1 is that people who want to do QA as a full-time career need to be able to code.
  3. The best QA people I’ve worked with in my career became more akin to business analysts (BAs) on the team, who were suggesting improvements to the user experience based on their knowledge of the business processes.
  4. A corollary to #1, #2, and #3 is that QA can add value by:
    • Being better at test automation than the developers.
    • Knowing the business better than the developers.
  5. Jobs that involve a large portion of repetitive, mechanistic work are begging to be automated away. Even slow-moving companies catch on eventually. Be the automator.

Conway’s Law & Remote Teams

Conway’s Law states:

organizations which design systems...are constrained to produce designs which are copies of the communication structures of these organizations.

In my last post, I wrote about how remote work tends to shine a light on areas where a software organization has been taking shortcuts and avoiding good design practices—things that are easier to workaround when everyone is within shouting distance.

If you subscribe to Conway’s Law, then it makes sense that the modularity of software designs would reflect the physical distribution of a software organization. It’s especially important that the work of remote developers can fit together across well-defined interfaces.

How much more important is self-documenting code when ad-hoc explanations are more laborious or time-shifted?

It’s fascinating to think of all the parallels that Conway’s Law implies between software design and a distributed workforce.

The Harsh Light of Remote Work

I came across the Remote Only manifesto recently, and while reading the points was struck by a common theme.

One of the major hurdles to remote work adoption is that it involves doing hard work in areas that people find tedious and hugely prefer to skip if they can get away with it.

Documenting things, standardizing things, careful and thorough written communication, having to examine carefully the work someone has produced to judge their performance, etc.

There are all sorts of ways to fudge these things when you all commute to the same building every day. You can see when someone is physically present in the building or not. You can get around poorly documented processes by tapping someone on the shoulder. The problem is, these things are all ephemeral and poor substitutes for actual value added.

harsh light

Effective remote work arrangements kind of force you to get your shit together as a working group and do the stuff you really should have been doing all along.

It's like when organizations get excited about open-sourcing a cool piece of their internally developed software. Suddenly when you're about to expose it to the light for general consumption, you realize all the design flaws that have left it tightly coupled to what should be isolated systems and how you don't have a reliable build process but have relied on Jerry who "sets you up" when you join the company so you can compile the damn thing. In short, it exposes all the places where you took shortcuts instead of sticking to good software design practices.

Remote work can shine a harsh light on the flaws of an organization. Walk into the light.

The private office is dead, long live the private office!

As someone who has been a vocal critic of open plan offices over the last several years, while also gleefully taking in the rise of remote work, I'm starting to wonder if it's time to give up the fight.

I find the sister phenomenon of the coworking space illuminating. An intentional open plan community for those fortunate souls privileged enough to look the quiet and privacy of a home office dead in the eye, turn their back, and instead pay a monthly fee for its near opposite.

coworking space

It's almost like the open plan and the home office represent the yin-yang of working environments.

Companies with large distributed workforces often have hot-desking arrangements in their facilities with a pleasing symmetry of a progressive work-from-home policy.

I may be giving up on the idea of employers going back to the days of private offices, and calling the whole discussion moot. Really, what are we more likely to see in the future: more companies building out private offices for their employees, or more companies unleashing their employees upon their own home offices? The answer is so obvious, that I'm not sure it's worth typing.

The private office is dead. Long live the private (home) office!

Humane Offices: The HN List (April 2018)

An Ask HN post hit the front page of Hacker News this month asking people to submit information about companies that specifically do not use open plan offices. I decided to comb through the comments and produce a clean listing of just the company names, with links to their websites, and, where applicable, the specific office location mentioned.

The Know-not-all Developer

In the Hacker News discussion of a recent post by a programmer who had publicly quit Google, I ran across a comment that I wished I could have sent back in time to the younger, angrier version of myself who was constantly frustrated with the goings-on at his early developer jobs.

People were debating how to win the “political game” that seems to determine one’s success in a larger organization. In discussions like this, I’ve noticed (and participated in) a common cynicism about “politics” amongst developers—that one’s technical merit is chronically underappreciated and that you must scheme your way to the top.

Hacker News comment

It took me years to come to the difficult realization that maybe the people who were placed in positions of authority were there because they had a better grasp of the needs of the business by which we were employed. Maybe they had strived to understand a broader context for their work and how it impacts the profitability of the company.

Are there boneheads in management? Of course! Just like there are at any level of an organization. But I personally found it better for my mental health and career satisfaction to develop some humility about my relationship to the broader organization.

My advice for a younger me would be this: Listen to the folks in your management chain that you have regular exposure to and try to develop a sense for the kinds of problems they tend to think are important, and then focus yourself on those areas. Also, you don’t know everything.
