When things go wrong in organizations, one thing is almost always found in the post-mortem: ‘human error’. No situation is too complex to be reduced to this simple, pernicious notion. ‘Human error’ has become a shapeshifting persona that can morph into an explanation of almost any unwanted event. With its various guises – ‘misjudgment’, ‘lapse of concentration’, ‘carelessness’ – it seeps into headlines and news reports. Twitter outage or train crash, the human is the culprit, error the cause.

But one only needs to look a little more deeply at the nature of system failures to see that things are not so straightforward. What seems to make sense as a causal catch-all for our everyday slips and blunders in life snaps when stretched; it fails to capture the context and complexity of our work and systems, and fails to help improve how things work. If the ‘human error’ explanation does not serve safety and business continuity, what does it serve? Perhaps it serves society’s need for simple explanations and someone to blame, while absolving it for its demands.

There is a better way, but it means that we have to refuse to oversimplify. Life after ‘human error’ means taking a road to recovery that takes a more nuanced and considered view of the person, system conditions, system behaviour and system outcomes. The good news is that the road is paved with concepts that help explain success as well as failure. A blend of humanistic thinking and systems thinking can improve both performance and wellbeing. This keynote will take a journey through the steps of recovery, from explaining away events to understanding how your system really works.

We need better visualizations of performance data to allow access to the wider teams we work with. Get your whole organization more involved and excited about performance work by making it more visible, attractive and adding the power of design to engage everybody.

Tell “data stories” rather than presenting a wall of numbers or graphs. Focus in on the one moment that captures the core problem or opportunity and don’t be afraid to keep the visuals very simple but then walk your team through the story of why it matters. Can you demonstrate how one second saved in loadtime might bring your organization significant additional revenue?

There’s only so much you can do to post-optimize the performance of an already designed website. To really move the performance numbers we need to establish shared design and performance principles before any design work begins. We need cross disciplinary team from day one that can iterate through prototypes in the browser to bring the design and performance choices to the fore.

I’ll present several case studies were performance principles have radically altered the course of the design process and is the direct result of having cross disciplinary teams and visualizing performance within the design process itself.

About Mark Zeman (SpeedCurve):
Mark Zeman is the founder of SpeedCurve a front-end performance monitoring service that gives you continuous feedback on how your front-end code is affecting the performance of your website.

Mark has spent 20 years designing for the web in a variety of roles from Creative Director to University Lecturer, Creative Technologist and Lead developer.

We live in the Impatience Economy where we want what we want, right here, and right now. Like most people, my dollar goes to the business that shows up, delivers and delights, while those who snooze loose. Big Data is often defined in terms of Variety, Volume and Velocity. How is Big Data re-defining Velocity? A new generation of startups are building a new class of big data driven applications that participate in Real-Time Bidding (RTB) to listen, learn, deliver and delight with personalized pages, product recommendations, pricing discounts and deals on devices, mobile apps and web portals across the Internet. The entire process from click to view completes in 150ms and each participant has just a few milliseconds in which to show up, decide whether to bid and how much to bid, to make the bid and if they win the auction, decide what to deliver in order to delight. Is there a common architecture emerging? How are these startups going from 0 to revenue in months, using high Velocity to create big Value?

Web development is becoming componentised. Whether via frameworks like React, native techniques like web components, or something else, components are rapidly becoming an essential part of web development. With them come tools and services designed to support teams using components, and cultural change too. This talk will make you think about the principles of your development process, with innovative approaches to style guides, component registries and other services to support new, more scalable web development practices. Using these new approaches requires modern browser features, so I’ll also be talking about a new public project sponsored by the FT and Fastly to build a community polyfill service. It’s time to upgrade the web.

Let’s face it. Alerting is broken. We are all still alerting the same way is we did in the early days of software based on metrics violations. We have all started to accept that we get too many alerts and the hard work of making sense is still left to us. This talk will introduce you to the concept of contextual alerting and show the difference hands on using a real world example.

As the complexity of the internet has grown, so too has the difficulty of monitoring your site. Between DNS, network complexity, infrastructure like home servers and CDNs, and bandwidth capacity, there is so much to keep track of – and much of it is outside of your own control.

So what can DevOps do to ensure that their sites are running as fast and reliably as possible?

Mehdi Daoudi, CEO and Co-founder of Catchpoint Systems, will draw upon his years of experience in the monitoring industry to highlight the many different factors that can cause a site to fail, and the best practices for avoiding them. He’ll highlight how success is about more than just preparation, it’s learning from the inevitable failures that you encounter along the way.

You may not be able to tame the beast completely, but you can certainly learn to avoid some of its more dangerous movements, and recover as quickly as possible from those that you can’t.

This keynote is sponsored by Catchpoint Systems.
