Resilience Engineering

Resilience Engineering

Origins

‘Resilience’ is a term that has been used for a long time and in several different ways. It was first used in to describe a property of timber, and to explain why some types of wood were able to accommodate sudden and severe loads without breaking. Almost four decades later, a report to the Admiralty referred to a measure called the modulus of resilience as a means of assessing the ability of materials to withstand severe conditions.

Rethinking the Triple Constraint: Five Project Dimensions

Karl Wiegers in The Startup Jun 14 · 11 min read

Perhaps you’ve seen a sign at an auto repair shop that asked, “What do you want: good, fast, or cheap? Pick two.” While humorous, the sign is also wise: it acknowledges the reality of trade-offs. You generally cannot optimize every desired outcome of a given situation.

The notion of such a “triple constraint” or “iron triangle” appears throughout project management. The problem is that I have seen numerous representations of the triangle with various parameters on the triangle’s vertices — size, cost, time, or scope — and various assumptions made about what is being held constant, such as quality or functionality. I’ve also seen diagrams that show four project dimensions. So, in my view, the traditional “triple constraint” is wrong, although the concept of constraints and trade-offs is certainly valid.

What is a squad health check model?

A lot of companies experiment with ways of measuring and visualizing how their teams are doing. They’re usually called “maturity models”, and involve some sort of progression through different levels.

The intent of these types of models is usually benign – for example managers or coaches in larger organizations who want to get a sense of where they should focus their improvement efforts, spot systemic problems, and help teams become more self-aware so they can focus their improvement efforts too.

Seven to Ten Years – AVC

I have worked in three venture capital firms over the last thirty-three years and am intimately familiar with the performance of the fifteen (ish) venture funds raised and invested by these three firms. Much of what I have written about fund management and investment performance here at AVC over the last sixteen years comes from my observations of these funds and firms.

Starting in the mid-00s, The Gotham Gal and I started investing in other venture capital funds, always limiting these investments to firms where we knew the partners well and had sat on boards with them.

4 Reasons Good Employees Lose Their Motivation

Paul Taylor/Getty Images

Motivation — the willingness to get the job done by starting rather than procrastinating, persisting in the face of distractions, and investing enough mental effort to succeed — accounts for 40% of the success of team projects. Yet managers are often at a loss as to how to effectively motivate uninspired employees. Our review of research on motivation indicates that the key is for managers to first accurately identify the reason for an employee’s lack of motivation and then apply a targeted strategy.

The Difference Between Open-Minded and Closed-Minded People

Why is it that some people seem to make constant progress in their professional and personal lives, while others appear to be doomed to repeat the same mistakes over and over?

While the answer isn’t cut and dry, I’ve noticed an interesting mindset difference between these two groups: they approach obstacles and challenges very differently. It comes down to mindset .

Successful people tend to approach life with an open mindset — an eagerness to learn and a willingness to be wrong. The other group digs their heels in at the first sign of disagreement and would rather die than be wrong.

“You mean he’s like an engineer-whisperer?”

Sorta.

Who is asking?

This question shows up over and over. And from all sides:

• the CEO who thinks her company is at the size that she should be “thinking” about hiring a VPE — the company is getting too big, and all of engineering still reports to her;
• the CTO who doesn’t want to manage people directly and is trying to figure out whether he needs a VPE to pair with — he feels that the best use of his time is to be the “chief architect”, “lead developer”, or “head prototyper”. The CTO often complains that he isn’t good at managing people, he isn’t scaling as a people manager as the team grows, that he finds people management is stressful, or he has no interest in doing it, and it’s a distraction;
• the first time VPE that is trying to figure out what she should be doing with her time — one-on-ones have already been scheduled, the current sprint has been planned, but what else should she be doing?; and, finally
• engineers who are concerned that the company wants to bring in “another level of management” — what does this do to their day to day? They often wonder what they’ve done wrong, or, whether they should be concerned that the company is getting “too large”.

Let’s pull this apart.

Undervalued Software Engineering Skills: Writing Well

I have been coaching several experienced software engineers to further grow professionally, since transitioning to being an engineering manager. I have noticed a few skills that people often underestimate the importance of developing. Skills that add a significant boost to the impact of any developer. One of these is writing.

Most software engineers primarily focus on becoming great at writing code. And this makes perfect sense. This is an essential step to become a great engineer within a reasonably sized team.

How to Hold Your Team Accountable – The Founder Coach

There’s a famous thought experiment in economics known as the “prisoner’s dilemma.” In it, two men have been caught committing a crime. Each of them is placed in a separate interrogation room and effectively has two options: confess or lie. There are three possible outcomes (the payoffs of which are illustrated in the payoff matrix below):

Our goal with product management at Gatsby is to create an ongoing and iterative product discovery and development process that allows us to ship customer value quickly and with confidence in our product–market fit. There are a lot of ways to break down product development and management.

Working the Weekly 1:1

A better approach for the most important meeting of the week

There are a lot of work “rituals” that suck so badly you want to hunt down and interrogate who ever invented them. The dreaded weekly status email is one of them. The weekly 1:1 between a boss and a direct report can be another. What should be a chance to get on the same page with the person critical to your success is often awkward, overly chummy or even skipped.

Gatsby Core Philosophy

Gatsby’s core philosophy can be divided into three parts.

First, our vision. Our vision is to construct higher-level web building blocks, and create a cohesive content mesh system, in order to make building websites fun and build a better web.

Second, our tooling philosophy. In order to make website building fun, Gatsby’s tooling must embody certain qualities. These include:

• bundling the modern JavaScript ecosystem
• progressive disclosure of complexity

Third, our community philosophy. We can’t do this alone, so we’re striving to build the most inclusive community on the web. For that reason, we work in the open. At all times, we believe, and strive to communicate, that you belong here.

Why a good boss likes it when people complain

I know some managers say “don’t bring me problems, bring me solutions,” but personally I don’t subscribe to it.

I love when people complain to me. Of course, complaining is a national past time for the British, and we don’t just limit ourselves to complaining about the weather, or the poor availability of good tea when traveling. Brexit has provided some strong fodder for complaining (where do we begin?) but really your average British can complain about anything.

‘Nothing Kept Me Up At Night the Way the Gorgon Stare Did.’

Arthur Holland Michel | Longreads | June 2019 | 15 minutes (3,946 words)

Drones have come to define the United States’ forever war, the so-called war on terror. The expansion of drone systems developed by the military into new territories — including the continental United States — embodies this era’s hyper-paranoid ethos: new threats are ever imminent, conflict is always without resolution. At the same time, non-militarized drones have entered civilian life in a number of ways, from breathtaking cinematography to flight control at Heathrow airport. There are many avid documenters of this new technology, but no one seems to understand its many facets quite like Arthur Holland Michel, founder and co-director of the Bard Center for the Study of the Drone, which catalogs the growing use of drones around the world. Now, Holland Michel has written Eyes in the Sky: The Secret Rise of Gorgon Stare and How It Will Watch Us All , a book of startling revelations about drone surveillance in the United States.

When people ask me what a VP of Engineering does, I like to reference the analogy Mark Suster used in a blog post clarifying the difference between a CTO and VPE :

Rugged Software

The Rugged Manifesto

I am rugged and, more importantly, my code is rugged.

I recognize that software has become a foundation of our modern world.

I recognize the awesome responsibility that comes with this foundational role.

I recognize that my code will be used in ways I cannot anticipate, in ways it was not designed, and for longer than it was ever intended.

I recognize that my code will be attacked by talented and persistent adversaries who threaten our physical, economic, and national security.

I recognize these things – and I choose to be rugged.

I am rugged because I refuse to be a source of vulnerability or weakness.

I am rugged because I assure my code will support its mission.

I am rugged because my code can face these challenges and persist in spite of them.

I am rugged, not because it is easy, but because it is necessary and I am up for the challenge.

Conscious Leadership

January 29, 2019

Conscious Leadership

Conscious Leadership is about being more interested in learning than being right. When our egos make us afraid to be wrong, that fear leads us to defend our ideas at all costs, and to work too hard to convince others that we are right—often with anger.

Conscious Leadership is about recognizing when these emotions (fear, anger, sadness) have gripped our thought processes, releasing these emotions, and shifting back to a state of curiosity where we are receptive to all ideas and creativity, even if they seem to contradict our own.

Into the Personal-Website-Verse · Matthias Ott – User Experience Designer

What started out as the most promising development in the history of the Web – the participation of users in the creation of content and online dialogue at scale – has turned into a swamp of sensation, lies, hate speech, harassment, and noise.

Your Unfriendly Neighborhood

Craving for attention and engagement, our timelines have changed. Algorithms now prioritize content from people with a huge following and everything that is loud and outrageous. It’s all about what the masses and the bots “want”, what they will like, share, and click. This strategy might be driving sales of ads because traditional online marketers are obsessed with quantity and it is – besides selling user data – the only answer they found for venture capital constantly demanding a bang for the buck. Yet it leads to an experience that is so often just more of the same and at the same time much less predictable, less organic, and less adjustable to your own preferences. As Craig Mod writes , “social networks seem more and more to say: You don’t know what you want, but we do.”

Friday wins and a case study in ritual design

Culture is what you celebrate. Rituals are the tools you use to shape culture.

Yet very few of us think much about ritual design.

A standard piece of software development practice that many teams let lapse, or merely let lapse into being sub-optimal is “Friday wins”, sometimes called sprint demos or sprint reviews. But you can take what can be a flaccid and repetitive meeting and make it a valuable ritual by grounding it in values.

Four Magic Numbers for Measuring Software Delivery

David Lush Mar 26

If you’ve read my previous post around ONZO’s engineering manifesto you will get a sense that we are proud of both our team culture and the way we deliver software. Late last year we started having conversations around “how do we elevate what we do to the next level as the team grows?”. Namely increasing our speed to market with new products while keeping a good grip on quality. We were using velocity as a planning tool, tracking quality through escaped bugs, had a handle on platform SLOs and working around a well formed roadmap. It felt like we were at risk of stagnating though.

Introducing Example Mapping

Before you pull a user story into development, it’s crucial to have a conversation to clarify and confirm the acceptance criteria.

Some people do this during their backlog refinement or planning poker sessions. Other teams have a specific three amigos meeting, specification workshop or discovery workshop .

Whatever you call this conversation, many teams find it hard; it’s unstructured, it takes too long and gets boring. The result is they don’t do it regularly or consistently, or maybe they just give up on it entirely.

“Time management” is not a solution — it’s actually part of the problem.

His boss had told him he needed to be more productive, so he had spent a few hours analyzing how he spent his time. He had already cut his nonessential meetings. He couldn’t find any tasks to drop from his calendar. He didn’t see an obvious way to do them more efficiently.

As a VC at Shasta Ventures , I look into technologies related to the “future of work” — automation/machine intelligence, collaboration/productivity, and much more. In this post, I’ll share thoughts on remote and distributed working.

I’ve always loved working in coffee shops. Maybe it’s the allure of being surrounded by people without having to talk to them. Maybe it’s the opportunity to strike up conversations with like-minded strangers. Maybe it’s just growing up in the Bay Area where people are on their laptops in public locations. More recently, I’ve been using time at coffee shops as a serendipitous way to learn more about remote work.

“Both/And” Leadership

The Problem

We look to leaders to make consistent decisions, keep a steady course, and align an organization’s culture. But leaders typically face multiple demands that conflict with one another, and it’s a mistake to assume there are cut-and-dried choices.

Why It Happens

Strategic paradoxes are essentially dilemmas that cannot be resolved. Tensions continually arise between today’s needs and tomorrow’s (innovation paradoxes), between global integration and local interests (globalization paradoxes), and between social missions and financial pressures (obligation paradoxes).

Book Review: Accelerate – slashdeploy – Medium

I didn’t know what expect from Accelerate, but I hoped the authors would delight me again. This review includes my thoughts, highlights, and lastly a recommendation on who it’s best for. Skip to the end if you’re just interested in the recommendation.

Finding the point of human leverage

One of the paradoxes of today’s internet platforms is they are vastly automated, and have no human control or interaction over what any given person sees, and yet they are also totally dependent on human behavior, because what they’re really doing is observing, extracting and inferring things from what hundreds of millions or billions of people do.

The genesis of this was PageRank. Instead of relying on hand-crafted rules to understand what each page might be about, or indexing the raw text, PageRank looks at what people have done or have said about that page. Who linked to it, what text did they use, and who linked to the people who linked to it? And at the other end of the pipe, Google gets every user to curate every set of search results by hand: it gives you 10 blue links and you tell Google which one was right. The same thing for Facebook: Facebook doesn’t know really know who you are, or what you’re interested in, or what that piece of content is. It knows who you follow, what you press ‘like’ on, who else liked that and what else they liked and followed. Facebook is PageRank for people. The same applies, by extension, to YouTube: it never knew what the video was, only what people typed next to it and what else they watched and liked.

Carta 101: How We Work

Note: Since this was published in 2015, some of our ideas have evolved, our revenue and burn rate have both increased, and our orientation has changed. But, as you’ll read later in the post, we still hope that people stay at Carta for a decade or more.

All Carta employees (new and old) take a full-day course called Carta 101. It is an introduction to our company, our values, and our execution strategy. The class size is kept small (8–10 people) so everyone can participate in the group discussions. I give this class on Fridays once a month.

The platform play: How to operate like a tech company

“The question is not how fast tech companies will become car companies, but how fast we will become a tech company.” This is how the board member of a global car company recently articulated the central issue facing most incumbents today: how to operate and innovate like a tech company.

The tech giants of today have been some of the most innovative companies in the past generation. A handful of industry leaders, such as Ping An and BMW, are fast joining their ranks by reinventing their core business around data and digital. What distinguishes these tech companies is that their technology allows them to move faster, more flexibly, and at greater scale than their competitors. IT is not a cumbersome estate “that gets in the way,” but an enabler and driver of continuous innovation and adaptation.

Coach Bill Campbell

I never met Bill Campbell. To be honest, I had never even heard about him until I heard Eric Schmidt speak his praises on the the Tim Ferris Podcast .

I picked up a copy of Trillion Dollar Coach and I’m so very glad I did. This book is easily in the top 5 books I’ve ever read. It’s right up there with Creativity Inc .

I don’t share book reports very often. Probably only 1 out of every 100-150 books I read. But this is one book that I felt compelled to share.

Does your team need to rebrand?

Some leaders are fantastic at “team branding”—communicating about their group in ways that give the rest of the organization a good understanding of what the team is all about. Others are squarely focused on “team public relations”—telling a great story about a team that, if we looked more closely, we might find is not delivering or functioning very well (it always comes out in the end).

Negative Splits

“Pain is inevitable. Suffering is optional. Say you’re running and you think, ‘Man, this hurts, I can’t take it anymore. The ‘hurt’ part is an unavoidable reality, but whether or not you can stand anymore is up to the runner himself.”
