If you find yourself thinking about what work lies ahead in 2018 consider the following. Doesn’t matter if you’re only thinking of the first month, quarter or the entire year. How many changes can your team handle before it culminates to where they’re no longer capable of performing their normal operations? How about for yourself?
While you’re considering your answer frame change as anything from work related to existing or new projects, ongoing work supporting existing products, incidents, pivots in priorities or business models, new regulations, reorgs, to just plain interruptions.
Every individual and team has a point where their capabilities become ineffective. We have different tools and methodologies that track time spent on tasks. We track complexity (story points) delivered in a given timeframe (sprints). Burn up charts show tasks added across time, but this is a very narrow view of change. A holistic view of the impact of change on a team is missing. One that can show how change wears down on the people we’re responsible for and ourselves.
Reduction of Capability
Before we started needing data for most decisions we placed trust in individuals to do their job. When people were being pushed too far too fast they might push back. This still happens, but the early signs of it are often drowned out by data or a mantra of stick with the process. It’s developed into a narrow focus that has eroded trust in experience to drive us towards our goals. This has damaged some of the basic leadership skills needed and it has focused our industry on efficiency over effectiveness. I’m also starting to think this is creating a tendency where people are second guessing their own abilities due to the inabilities of others.
This reinforces a culture where leaders stop trusting the opinions of people doing the work or those who are close to it. When people push back the leaders have a choice to either listen and take into account the feedback or to double down on the data and methods used. This contributed in creating the environments where the labels “10x”, “Rock Stars” and “Ninjas” started being applied to engineers, designers, and developers.
heroics — “behavior or talk that is bold or dramatic, especially excessively or unexpectedly so: the makeshift team performed heroics.” — New Oxford American Dictionary
Ever think about why we apply the label heroics or hero when teams or people are able to pull through in the end? If the output of work and the frequency of changes were plotted I’d bet you’ll find the point where sustaining normal operations was impracticable or improbable was passed before these labels are used.
Last month’s fatal Amtrak derailment that killed three people was traveling more than twice the speed limit (80 mph in a 30 mph zone). The automated system (positive train control) designed to prevent these types of conditions from happening while installed was not activated. Was this fatal accident on the inaugural run of a new Amtrak route an example of where normal operations were no longer possible? Is this any different than the fatal collisions involving US Navy ships last year due to over-burdened personnel and equipment?
For the derailment it looks like a combination of failing to use available safety systems and following safety guidelines contributed to the accident. There’s also the question was the crew given training to build awareness of the new route. The Navy collisions looks to be the result of the strain of trying to do too much with too few people and resources. This includes individuals working too many hours, a reduction in training, failure to verify readiness, and a backlog of maintenance on the equipment, aircraft and ships.
The cadence of change was greater than what these organizations were capable of supporting.
For most of us working as engineers, designers, developers, product managers, or as online support we wouldn’t consider ourselves to be in a high-risk occupation. But the work we do impacts peoples lives in small to massive ways. These examples are something that we should be learning from. We should also acknowledge that we’re not good at being aware of the negative impacts of the tempo of change on our people.
There’s a phrase and image that can illustrate the dependencies between people, processes, and systems. It’s called the “Swiss Cheese Model” and it highlights when shortcomings between them line up it can allow a problem to happen. It also shows how the strengths from each is able to support the weaknesses of others.

We have runbooks, playbooks, incident management processes, and things to help us understand what is happening in our products and systems. Remember that these things are not absolute and they’re fallible. The systems and processes we put into place are never final, they’re ideas maintained as long as they stay relevant and then removed when they are no longer necessary. This requires awareness and diligence.
In any postmortem I’ve participated in or read through there were early signs that conditions were unusual. Often people fail to recognize a difference between what is happening and what is expected to happen. This is the point where a difference can start to develop into a problem if we ignore it. If you think you see something that doesn’t seem right you need to speak up.
After the Apollo 1 fire Gene Kranz gave a speech to his team at NASA that is knows as the Kranz Dictum. He begins by stating they work in a field that cannot tolerate incompetence. He then immediately holds himself and every part of the Apollo program accountable for their failures to prevent the deaths of Gus Grissom, Ed White, and Roger Chaffee.
From this day forward, Flight Control will be known by two words: “Tough” and “Competent.” Tough means we are forever accountable for what we do or what we fail to do. We will never again compromise our responsibilities. Every time we walk into Mission Control we will know what we stand for. Competent means we will never take anything for granted. We will never be found short in our knowledge and in our skills. — Gene Kranz
I take this as doing the work to protect the people involved. For us this should include ourselves, the people in our organizations, and our customers. Protection is gained when we’re thorough and accountable; sufficient training and resources are given; communication is concise and assertive; and we have an awareness of what is happening.
When I compare the derailment and collisions, what Kranz was speaking too, any emergency I responded to as a fire fighter, or any incident I worked as an engineer there are similarities. They’re the results from the attrition of little things that continued unabated.
Andon Cord for People
Alerting, availability, continuous integration/deployment, error rates, logging, metrics, monitoring, MTBF, MTTF, MVP, observability, reliability, resiliency, SLA, SLI, SLO, telemetry, throughput and uptime.
We build tools and we have all kinds of words and acronyms to help us frame our thoughts around the planning, building, maintaining and supporting of products. We even allow machines to bug us to fix them, including waking us up in the middle of the night. Why don’t we have the same level of response when people break?
One of the many things that came out of the Toyota Production System is Andon. It gives individuals the ability to stop the production line when a problem is found and call for help.
We talk about rapid feedback loops and iterative workflows, but we don’t talk about feedback from the people close to the work as a way of continuous improvement. We should be giving people the ability to pull the cord when there is an issue that impacts the ability for them or someone else on the team to perform. And that doesn’t mean only technical issues.
What would happen if your on-call staff had horrible time that they’re spent after their first night? Imagine if we gave our people the same level of support that we give our machines? Give them an andon cord to pull (i.e. page) that would get them the help they need.
As you’re planning don’t forget about your people. Could you track the frequency of changes happening to your team? Then plot the impact of that against the work completed? Think about providing an andon cord for them. How could you build a culture where people feel responsible to speak up when they see something that doesn’t line up with what we expect?
“People, ideas and technology. In that order!” — John Boyd.
Too many times we think a solution or problem is technical. More often than not it’s about a breakdown of communication and then sometimes not having the right people or protecting them.
The ideas from Boyd are a good example of how our industry fails to fully understand a concept before using it. If you’ve heard the phrase OODA Loop you’ve probably seen a circular image with points for Observe, Orient, Decide and Act. The thing is he never drew just a single loop. He gave a way to frame an environment and a process to help guide us through the unknowns. And it puts the people first by using their experience so when they recognize something for what it is they can act on it immediately. It was always more than a loop. It was a focus on the people and organizations.
